Answer: second option.

Step-by-step explanation:

In order to solve this exercise, it is necessary to remember the following properties of logarithms:

[tex]1)\ ln(p)^m=m*ln(p)\\\\2)\ ln(e)=1[/tex]

In this case you have the following inequality:

[tex]e^x>14[/tex]

So you need to solve for the variable "x".

The steps to do it are below:

1. You need to apply [tex]ln[/tex] to both sides of the inequality:

[tex]ln(e)^x>ln(14)[/tex]

2. Now you must apply the properties shown before:

[tex](x)ln(e)>ln(14)\\\\(x)(1)>2.63906\\\\x>2.63906[/tex]

3. Then, rounding to the nearest ten-thousandth, you get:

[tex]x>2.6391[/tex]

Answer:

he rank from least to great based on their axis of symmetry:

0, 1, -3 ⇒ g(x), h(x), f(x)

So, option C is correct.

Step-by-step explanation:

A quadratic equation is given by:

[tex]ax^2+bx+c =0[/tex]

Here, a, b and c are termed as coefficients and x being the variable.

Axis of symmetry can be obtained using the formula

[tex]x = \frac{-b}{2a}[/tex]

Identification of a, b and c in f(x), g(x) and h(x) can be obtained as follows:

[tex]f(x) = x^2 + 6x - 1[/tex]

⇒ a = 1, b = 6 and c = -1

[tex]g(x) = -x^2 + 2[/tex]

⇒ a = -1, b = 0 and c = 2

[tex]h(x) = 2^2 - 4x + 3[/tex]

⇒ a = 2, b = -4 and c = 3

So, axis of symmetry in [tex]f(x) = x^2 + 6x - 1[/tex] will be:

[tex]x = \frac{-b}{2a}[/tex]

x = -6/2(1) = -3

and axis of symmetry in [tex]g(x) = -x^2 + 2[/tex] will be:

[tex]x = \frac{-b}{2a}[/tex]

x = -(0)/2(-1) = 0

and axis of symmetry in [tex]h(x) = 2^2 - 4x + 3[/tex] will be:

[tex]x = \frac{-b}{2a}[/tex]

x = -(-4)/2(2) = 1

So, the rank from least to great based on their axis of symmetry:

0, 1, -3 ⇒ g(x), h(x), f(x)

So, option C is correct.

Answer:the greatest number of pieces that can be cut is 2

Step-by-step explanation:

The total length of ribbon available is 3/4 meter. Sunday needs pieces measuring 1/3 meter for their project. This means that each length needed would be exactly 1/3 meter.

The number of pieces measuring 1/3 meter that can be cut from the ribbon would be

(3/4)/(1/3) = 3/4×3/1 = 9/4 = 2.25

Since the length needed is exactly 1/3 meter, the greatest number of pieces that can be cut will be 2

Answer:

Base of triangle is 9 inches and altitude of triangle is 14 inches.

Step-by-step explanation:

Given:

Area of Triangle = 63 sq. in.

Let base of the triangle be 'b'.

Let altitude of triangle be 'a'.

Now according to question;

altitude is 5 inches longer than the base.

hence equation can be framed as;

[tex]a=b+5[/tex]

Now we know that Area of triangle is half times base and altitude.

Hence we get;

[tex]\frac{1}{2} \times b \times a =\textrm{Area of Triangle}[/tex]

Substituting the values we get;

[tex]\frac{1}{2} \times b \times (b+5) =63\\\\b(b+5)=63\times2\\\\b^2+5b=126\\\\b^2+5b-126=0[/tex]

Now finding the roots for given equation we get;

[tex]b^2+14b-9b-126=0\\\\b(b+14)-9(b+14)=0\\\\(b+14)(b-9)=0[/tex]

Hence there are 2 values of b[tex]b-9 = 0\\b=9\\\\b+14=0\\b=-14[/tex]

Since base of triangle cannot be negative hence we can say [tex]b=9\ inches[/tex]

So Base of triangle = 9 inches.

Altitude = 5 + base  = 5 + 9 = 14 in.

Hence Base of triangle is 9 inches and altitude of triangle is 14 inches.

Answer:

After 4 miles driven by cab the amount would be same in both cities.

Step-by-step explanation:

Let the number of miles be 'x'.

Given:

In NYC

Flat fee of cab = $4

Per mile charge = $1.25

Total cab charges is equal to sum of Flat fee of cab and per mile charge multiplied by number of miles.

Framing in equation form we get;

Total cab charges in NYC = [tex]4+1.25x[/tex]

In Chicago

Flat fee of cab = $6

Per mile charge = $0.75

Total cab charges is equal to sum of Flat fee of cab and per mile charge multiplied by number of miles.

Framing in equation form we get;

Total cab charges in Chicago = [tex]6+0.75x[/tex]

Now we need to find number of miles driven so that the amount could same in both cities.

Total cab charges in NYC = Total cab charges in Chicago

[tex]4+1.25x=6+0.75x[/tex]

Combining like terms we get;

[tex]1.25x-0.75x=6-4\\\\0.5x=2[/tex]

using Division Property we will divide both side by 0.5 we get;

[tex]\frac{0.5x}{0.5} =\frac{2}{0.5} \\\\x=4[/tex]

Hence After 4 miles driven by cab the amount would be same in both cities.

Option A

Interest rate paid by Samantha to bank is 8.6 %

Solution:

Given that George has a credit score of 650

Samantha has a credit score of 520

The bank approved George’s loan application at 5.6% interest

To find: Interest rate paid by samantha to the bank

From given information in question,

Interest charged on Samantha’s loan is 3 percentage points higher than the interest rate on George’s loan

Thus we get,

Interest charged on Samantha’s loan = 3 percentage points higher than the interest rate on George’s loan

Interest charged on Samantha’s loan = 3 % higher than the interest rate on George’s loan

Interest charged on Samantha’s loan = 3 % + interest rate on George’s loan

Thus substituting the given George’s loan application at 5.6% interest,

Interest charged on Samantha’s loan = 3 % + 5.6 % = 8.6 %

Thus interest rate paid by samantha to bank is 8.6 %

Final answer:

Option A: 8.6%

Samantha will pay an interest rate of 8.6% on her loan from Westside Bank, which is 3 percentage points higher than George's rate of 5.6% due to her lower credit score.

Explanation:

The question involves calculating the interest rate Samantha will pay to the bank for a personal loan.

Given that George has a credit score of 650 and was approved for a loan at 5.6% interest, and Samantha has a lower credit score of 520, her interest rate will be 3 percentage points higher than George's.

To find Samantha's interest rate, we simply add 3 percentage points to George's rate of 5.6%.

Samantha's interest rate = George's interest rate + 3%
Samantha's interest rate = 5.6% + 3%
Samantha's interest rate = 8.6%

Answer:

The number of child tickets sold was 36

Step-by-step explanation:

The complete question is

At the city museum, child admission is $5.80 and adult admission is $9.30. On Monday, four times as many adult tickets as child tickets were sold, for a total sales of $1548.00. How many child tickets were sold that day?

Let

y ----> the number of adult tickets sold

we know that

[tex]5.80x+9.30y=1,548.00[/tex] ---> equation A

[tex]y=4x[/tex] ----> equation B

Solve by substitution

Substitute equation B in equation A    

[tex]5.80x+9.30(4x)=1,548.00[/tex]

solve for x

[tex]5.80x+37.2x=1,548.00[/tex]

[tex]43x=1,548.00[/tex]

[tex]x=36[/tex]

Answer:16 days

Step-by-step explanation:

Given

John schedule is 4 Workdays and 5 th day off i.e. John take holiday at the 5 th day

Ling Work for 7 day and then took off on 8 th and 9 th day

i.e. after every 8 th and 9 th day he take off

So to find out common day off we nee take LCM of

i)5 and 8

ii)5 and 9

LCM(5,8)=40 i.e. after every 40 th day they had same day off

and there are 8 such days in 365 days

LCM(5,9)=45 i.e. after every 45 day they had same day off

and there are total of 8 days in 365 days

therefore there are total of 16 days in total out of 365 days

By computing the LCM of their work schedules, John and Ling will have the same day off 8 times during their first year of work.

This problem can be approached using the concept of Least Common Multiple (LCM) which is widely used in mathematics to solve similar problems. Here we need to calculate the frequency of John and Ling's common days off.

John's schedule repeats every 5 days (4 workdays followed by 1 day off) and Ling's schedule repeats every 9 days (7 workdays followed by 2 days off). To know how often they both have a day off on the same day, we need to find the LCM of 5 and 9. Interestingly, since 5 and 9 are prime to each other, their LCM will be their product, which is 45. Therefore, John and Ling will have a day off together every 45 days.

To know how many such days will be there in a year, divide 365 by 45 which equals 8.111. Since the number of days cannot be fractional, we take only the whole number part which is 8. So, during the first year of their work (365 days), John and Ling will have the same day off on 8 days.

Answer:

Step-by-step explanation:

k = 6

To find the value of k, rationalize the denominator of 2/√3, and compare it with 2k/3 to find k = √3.

To rationalize the denominator of the fraction 2/√3, we need to make the denominator a rational number. We can do this by multiplying both the numerator and the denominator by √3.

So, after rationalizing, the fraction becomes 2√3/3. According to the problem statement, this is equivalent to 2k/3.

Therefore, we can equate 2k to 2√3:

2k = 2√3

k = √3

So, the value of k is √3.

The complete question is

When the denominator of 2/√3 is rationalized ,it becomes 2k/3​. Find k

a) The recurrence relation for the number of ternary strings of length n that do not contain two consecutive 0s is [tex]\(a_n = 2a_{n-1} + a_{n-2}\).[/tex]

b) The initial conditions for the recurrence relation are [tex]\(a_1 = 3\) and \(a_2 = 9\).[/tex]

c) There are 21 ternary strings of length six that do not contain two consecutive 0s.

a) To derive the recurrence relation, consider the possibilities for the last digit in the string. If the last digit is 1 or 2, it doesn't affect the constraint of avoiding consecutive 0s. Hence, for strings of length n that end in 1 or 2, there are[tex]\(a_{n-1}\)[/tex]possibilities. However, if the last digit is 0, the previous digit cannot be 0 to satisfy the constraint. Therefore, for strings of length n that end in 0, there are \(a_{n-2}\) possibilities. This results in the recurrence relation[tex]\(a_n = 2a_{n-1} + a_{n-2}\).[/tex]

b) The initial conditions are established by considering strings of length 1 and 2. For strings of length 1, there are three possibilities (0, 1, or 2). For strings of length 2, there are nine possibilities (00, 01, 02, 10, 11, 12, 20, 21, 22), but among these, 00 is excluded to avoid consecutive 0s, leaving a total of nine valid strings. Therefore, the initial conditions are[tex]\(a_1 = 3\) and \(a_2 = 9\).[/tex]

c) To find the number of ternary strings of length six that do not contain two consecutive 0s, utilize the recurrence relation. Starting from the initial conditions, compute[tex]\(a_6 = 2a_5 + a_4\)[/tex] using the relation, which results in [tex]\(a_6 = 21\).[/tex]

Thus, there are 21 ternary strings of length six that satisfy the condition of not having two consecutive 0s.

"In summary, the recurrence relation [tex]\(a_n = 2a_{n-1} + a_{n-2}\)[/tex]governs the number of ternary strings of length n without consecutive 0s, with initial conditions[tex]\(a_1 = 3\) and \(a_2 = 9\)[/tex]. Computing[tex]\(a_6\)[/tex]using the relation yields 21 valid ternary strings of length six that do not contain two consecutive 0s."

The recurrence relation for the number of ternary strings of length n that do not contain two consecutive 0s is a_n = 2a_n-1 + 2a_n-2. The initial conditions are a_1 = 3 and a_2 = 8. Using these, we calculate that there are 448 such ternary strings of length six.

Ternary Strings without Consecutive 0s

Let's define a ternary string as a string composed of the digits 0, 1, and 2. We need to find a recurrence relation for the number of such strings of length n that do not contain two consecutive 0s.

Part (a)

Let a_n represent the number of ternary strings of length n that do not contain consecutive 0s. Consider the possibilities for the first digit of the string:

Thus, we have the recurrence relation: a_n = 2a_{n-1} + 2a_{n-2}

Part (b)

The initial conditions can be determined as follows:

Part (c)

Using the recurrence relation and initial conditions:

Therefore, the number of ternary strings of length six that do not contain two consecutive 0s is 448.

Here in this question,

[tex]\left(x_{1}, y_{1}\right)=(10,14) \text { and }\left(x_{2}, y_{2}\right)=(4,-2)[/tex]

Denzel took 1/40 of his earnings to the park but did not spend it on rides or popcorn.

Let's break down the information provided step by step to find the fraction of Denzel's earnings that he took to the park but did not spend on rides or popcorn.

Denzel put 1/2 of his earnings into savings. This means he kept 1/2 as his spending money for the amusement park.

Denzel spent 1/5 of the remaining amount on popcorn. This means he spent 1/5 * 1/2 = 1/10 of his earnings on popcorn.

Denzel also spent 3/4 of the remaining amount on rides. This means he spent 3/4 * 1/2 = 3/8 of his earnings on rides.

To find the fraction of his earnings that he took to the park but did not spend on rides or popcorn, we need to subtract the fractions spent on rides and popcorn from the fraction he took to the park.

Fraction taken to the park but not spent on rides or popcorn = 1/2 - (1/10 + 3/8)

To subtract fractions, we need a common denominator. The least common multiple of 10 and 8 is 40.

Converting the fractions to have a common denominator:

1/2 - (1/10 + 3/8) = 20/40 - (4/40 + 15/40) = 20/40 - 19/40 = 1/40

Therefore, Denzel took 1/40 of his earnings to the park but did not spend it on rides or popcorn.

Question: Denzel earned money after school. He put 1/2 of this month's earnings into savings. He took the rest to spend at the amusement park. He spent 1/5 of this amount on popcorn and 3/4 of it on rides. What fraction of his earnings did he take to the park but not spend on rides or popcorn?

This question is pretty much asking if you know how to use your trig identities if i understand it correctly.

Final answer:

To rewrite cos 3x using only sin x and cos x, we can use the trigonometric identity: cos 3x = 4(cos x)^3 - 3(cos x). This identity allows us to express cos 3x in terms of cos x. However, if we want to rewrite it using only sin x and cos x, we can use the Pythagorean identity: (cos x)^2 = 1 - (sin x)^2.

Explanation:

To rewrite cos 3x using only sin x and cos x, we can use the trigonometric identity: cos 3x = 4(cos x)^3 - 3(cos x). This identity allows us to express cos 3x in terms of cos x. However, if we want to rewrite it using only sin x and cos x, we can use the Pythagorean identity: (cos x)^2 = 1 - (sin x)^2. So, we can substitute this identity into the previous equation to get: cos 3x = 4(1 - (sin x)^2)^3 - 3(1 - (sin x)^2).

Answer:

  36 square feet

Step-by-step explanation:

The area of one barrier is the product of the given dimensions:

  (9 ft)(2 ft) = 18 ft²

Two such barriers will have twice the area: 36 ft².

The combined area of the two barriers is calculated by multiplying the length by the height for each barrier to get an area for each one, and then those two areas are added together. Each barrier has an area of 18 square feet, so the total combined area is 36 square feet.

The question is asking for the combined area of two barriers, each being 9 feet long and 2 feet high. In order to find this, we must multiply the length by the height for each barrier, and then add these two areas together. The calculation would look like this:

Area of each barrier = Length x Height = 9 ft x 2 ft = 18 square feet

Now, since there are two barriers:

Combined Area = 2 x Area of each barrier = 2 x 18 square feet = 36 square feet

Therefore, the combined area of the two barriers is 36 square feet.

The equation of parabola is expressed as: y² = -20x

What is the equation of the parabola?

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line.

The fixed point is called the focus of the parabola, and the fixed line is called the directrix of the parabola.

Given, vertex = (0, 0)

Focus = (-5, 0)

We have to find the equation of the parabola.

The equation is of the form y = -ax²

Directrix x = 5.

As every point on parabola is equidistant from focus and directrix, the equation will be

y² + (x + 5)² = (x - 5)²

y² + x² + 10x + 25 = x² - 10x + 25

y² = - 10x - 10x

y² = -20x

Therefore, the equation of parabola is y² = -20x

Number of cups required = 6 cups

Measuring cup capacity = [tex]\frac{1}{4}=0.25[/tex] of a cup.

Now, each time the measuring cup fills 0.25 of a cup.

So, we use unitary method to find the number of times the measuring cup has to be used to get a total of 6 cups.

∵ 0.25 cups = 1 time the measuring cup being used.

∴ 1 cup = [tex]\frac{1}{0.25}=4[/tex] times the measuring cup being used.

So, 6 cups = [tex]4\times 6=24[/tex] times the measuring cup being used.

Hence, the number of times the measuring cup has to be used to get 6 cups of flour is 24 times.

God is with you!!!

Answer: False

Step-by-step explanation: When we are asked to determine whether two ratios form a proportion, what we are really being asked to do is to determine whether the ratios are equal because if the ratios are equal, then we know they form a proportion.

So in this problem, we need to determine whether 3/2 = 18/8. The easiest way to determine whether 3/2 = 18/8 is to use cross products. If the cross products are equal, then the ratios are equal.

The cross products for these two ratios are 3 x 8 and 2 x 18.

Since 3 x 8 is 24 and 2 x 18 is 36, we can easily see that 24 ≠ 36 so the cross products are not equal which means that the ratios are not equal and since the ratios are not equal, we know that they do not form a proportion.

So the answer is false. 3/2 and 18/8 do not form a proportion.

Answer:the number of miles that Henry traveled is 15

Step-by-step explanation:

The equation representing Henry's cab ride would be

3 + 0.50m = 10.50

Subtracting 3 from both sides of the equation, it becomes

3 - 3 + 0.50m = 10.50 - 3

0.5m = 7.5

m = 7.5/0.5 = 15 miles
