Use The Laws Of Logarithms And The Values Given Below To Evaluate The Logarithmic Expression. Log7=0.8451

Answers

Answer 1

Answer:

B

Step-by-step explanation:

We can use the logarithm property shown below to evaluate this:

[tex]Log(x*y*z)=logx+logy+logz[/tex]

Now we can write Log 12 as Log (2*2*3).

Using the rule, we can write:

Log (2*2*3) = Log 2 + Log 2 + Log 3

We are given values of Log 2 and Log 3, plugging these we get:

Log (2*2*3) = Log 2 + Log 2 + Log 3

Log (2*2*3) = 0.3010 + 0.3010 + 0.4771 = 1.0791

Answer choice B is right.

Answer 2

We can factor out 12 using 2 and 3.

log(12) = log(2^2 * 3)

Rewrite it using the product rule [ log(xy) = log(x) + log(y) ]

log(2^2 * 3) = 2 log(2) + log(3)

Simplify using the given values.

2(0.3010) + 0.4771

0.602 + 0.4771

1.0791

Therefore, the answer is b. ≈ 1.0791

Best of Luck!

Final answer:

To find the cosine of the angle formed by the line y=2x and the positive x-axis, we calculate the arctangent of the slope (2), which gives us an angle of approximately 63.435 degrees. The cosine of this angle is then approximately 0.447 to the nearest thousandth.

Explanation:

The question is asking for the cosine of the angle formed between the line y = 2x and the positive x-axis. To find this, we first need to determine the angle that the line makes with the x-axis. The slope of the line, given by m, is 2, which also represents the tangent of the angle the line forms with the x-axis (tan(θ) = m). We can calculate the angle using the arctangent function (tan⁻¹).

θ = tan⁻¹(2) = Approx. 63.435 degrees

The cosine of this angle can be found using the cosine function:

cos(θ) = cos(63.435 degrees) = Approx. 0.447

To the nearest thousandth, the cosine of the angle is 0.447.

You got a job selling books at the mall. You are paid $70 per day plus $2 for each book you sell. Which recursive formula models this situation?

Answers

Answer:

f(x) = 70 + 2x

Step-by-step explanation:

In this problem, we first need to consider how much we get per day.

$70 is our constant.

$2 will be dependent on the number of books sold.

Here 'x' will represent the number of books sold.

f(x) = 70 + 2x

Now let's try it out.

Let's say we sold 0 books

f(0) = 70 + 2(0) = 70

This shows us that we only get our constant pay.

Now let's try for 1 or more books.

f(1) = 70 + 2(1) = 72

f(2) = 70 + 2(2) = 74

So the recursive formula f(x) = 70 + 2x is a good formula to model the situation.

Two particles move in the xy-plane. At time t, the position of particle A is given by x(t)=5t−5 and y(t)=2t−k, and the position of particle B is given by x(t)=4t and y(t)=t2−2t−1.(a) If k=−6, do the particles ever collide?(b) Find k so that the two particles are certain to collide.k=(c) At the time the particle collide in (b), which is moving faster?A. particle AB. particle BC. neither particle (they are moving at the same speed)

Answers

Answer:

a. No the particles will never collide.

b. The second particle is moving faster.

Step-by-step explanation:

We can tell they never collide based on the fact that they will never have the same two points. We can tell this because there is only one time in which they will have the same x value. To find this amount of time, set the two x values equal to each other and solve for t.

5t - 5 = 4t

-5 = -t

5 = t

So we know the x value will only be the same at 5 seconds. Now we can input that value and see if the y values are the same.

2t + 6 = t^2 - 2t - 1

2(5) + 6 = 5^2 - 2(5) - 1

10 + 6 = 25 - 10 - 1

16 = 14 (FALSE)

Therefore they do not collide.

For the second part of the question, we know that the second one is moving faster based on the fact that there is a squared value in the y formula. This shows that it is moving at an exponential rate, which always changes faster than a linear rate.

Particle A and particle B never collide.

The value of k where the particles collide is k = -4

The particle that is moving faster is Particle B since it has a square root in the y(t) = t² - 2t - 1.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Two particles:

Particle A:

x(t) = 5t - 5

y(t) = 2t - k

Particle B:

x(t) = 4t

y(t) = t² - 2t - 1

We see that,

The x(t) of particle A and x(t) of particle B are the same only at t = 5.

x(t) = 5t - 5 = 5 x 5 - 5 = 25 - 5 = 20

x(t) = 4t = 4 x 5 = 20

Now,

y(t) = 2t - k = 2 x 5 - k = 10 - k

y(t) = t² - 2t - 1 = 25 - 10 - 1 = 25 - 11 = 14

(a) If k = -6.

x(t) = 5t - 5 = 5 x 5 - 5 = 25 - 5 = 20

x(t) = 4t = 4 x 5 = 20

y(t) = 2t - k = 2 x 5 - k = 10 - k = 10 + 6 = 16

y(t) = t² - 2t - 1 = 25 - 10 - 1 = 25 - 11 = 14

In order to collide both the x(t) of particles A and B must be the same.

Similarly, y(t) must be the same.

So,

Particle A and particle B never collide.

(b)

The value of k where the particles collide.

k = -4

y(t) = 2t - k = 2 x 5 - k = 10 - k = 10 + 4 = 14

y(t) = t² - 2t - 1 = 25 - 10 - 1 = 25 - 11 = 14

(c)

The time at which the particles collide.

t = 5 and k = -4

x(t) = 5t - 5 = 5 x 5 - 5 = 25 - 5 = 20

x(t) = 4t = 4 x 5 = 20

y(t) = 2t - k = 2 x 5 - k = 10 - k = 10 + 4 = 14

y(t) = t² - 2t - 1 = 25 - 10 - 1 = 25 - 11 = 14

The particle that is moving faster is Particle B since it has a square root in the y(t) = t² - 2t - 1.

Thus,

Particle A and particle B never collide.

The value of k where the particles collide is k = -4

The particle that is moving faster is Particle B since it has a square root in the y(t) = t² - 2t - 1.

The length of a rectangular park is 3 feet shorter than times its width. If the length is 123 feet, what is the width of the park in feet?

Answers

Final answer:

The width of the rectangular park is 126 feet. This was found by setting up an equation based on the problem description and then solving for the width.

Explanation:

The subject of this question is Mathematics, specifically algebra. The problem states that the length of a rectangular park is 3 feet shorter than its width, with the length being given as 123 feet.

First of all, let's define the length with a variable L and the width with a variable W. From the problem, we can write the equation, L = W - 3. Since we know that L = 123 feet, we can substitute this value into the equation, getting 123 = W - 3.

To find W, all we need to do is add 3 to both sides of the equation. Hence, W = 123 + 3 = 126 feet. So, the width of the park is 126 feet.

The length of a rectangle is four times its width. If the area of the rectangle is 100 ft?, find its perimeter

Answers

The width of the rectangle is 5 feet, its length is 20 feet. Thus, the perimeter is 50 feet.

To solve this problem, let's denote:

- Width of the rectangle as  w  (in feet)

- Length of the rectangle as 4w  (since it's four times the width)

Given that the area of the rectangle is 100 square feet, we can set up the equation for the area:

[tex]\[ \text{Area} = \text{Length} \times \text{Width} \][/tex]

[tex]\[ 100 = (4w) \times w \][/tex]

[tex]\[ 100 = 4w^2 \][/tex]

Now, let's solve for ( w ):

[tex]\[ 4w^2 = 100 \][/tex]

Divide both sides by 4:

[tex]\[ w^2 = 25 \][/tex]

Taking the square root of both sides:

[tex]\[ w = \sqrt{25} \][/tex]

[ w = 5 ]

So, the width of the rectangle is ( w = 5 ) feet.

Now, we can find the length:

[tex]\[ \text{Length} = 4w = 4(5) = 20 \] feet.[/tex]

Now that we have both the width and length, we can find the perimeter of the rectangle using the formula for perimeter:

[tex]\[ \text{Perimeter} = 2(\text{Length}) + 2(\text{Width}) \][/tex]

[tex]\[ \text{Perimeter} = 2(20) + 2(5) \][/tex]

[tex]\[ \text{Perimeter} = 40 + 10 \][/tex]

[tex]\[ \text{Perimeter} = 50 \][/tex]

So, the perimeter of the rectangle is ( 50 ) feet.

Suppose f is a continuous function defined on a closed interval a,

b. (a) what theorem guarantees the existence of an absolute max- imum value and an absolute minimum value for f ? (b) what steps would you take to find those maximum and minimum values?

Answers

Answer:

Step-by-step explanation:

(a) The Extreme Value Theorem.

(b)  We would differentiate the function and equate this to zero. The zeroes of the function will give us the values of the maxima / minima and we can find find the absolute maxima/minima from the results. Note we might have  multiple relative maxima/ minima  but only one absolute maximum and one absolute minimum.

Final answer:

The Extreme Value Theorem guarantees that a continuous function on a closed interval has an absolute maximum and minimum. To find these, one calculates the derivative to find critical points, analyzes the derivative's sign around these points, and evaluates the function at the critical points and the interval's endpoints.

Explanation:

Extreme Value Theorem and Finding Maximum and Minimum Values

The theorem that guarantees the existence of both an absolute maximum and minimum value for a continuous function defined on a closed interval a, b is known as the Extreme Value Theorem. This theorem plays a crucial role in calculus and mathematical analysis and is fundamental in understanding the behavior of continuous functions on closed intervals.

To find these maximum and minimum values, one would typically follow these steps:

Calculate f'(x), the derivative of the function f(x), to find the critical points.

Analyze the sign of f'(x) around the critical points to determine if they are local minima, local maxima, or saddle points.

Evaluate the function f(x) at each critical point as well as the endpoints of the interval [a, b] to determine the absolute extrema.

Moreover, if a function satisfies the criteria of being continuous on [a, b] and differentiable on (a, b), then by a related theorem called the Mean Value Theorem, there exists at least one c in (a, b) where f'(c) = 0.

These methods form the standard procedure for finding the extremal values that a continuous function may possess on a closed interval.

When b= 0.5, the period of orange graph is _ pi

When b= 2, the period of orange graph is _ pi

Answers

Answer:

When b= 0.5, the period of orange graph is _4_ pi

When b= 2, the period of orange graph is _1_pi

Step-by-step explanation:

The period of the sinusoidal functions can be easily calculated by observing their graphs.

First, look at the orange graph when b = 0.5

Identify a point where the orange chart cuts the x-axis. For example at [tex]x = 0[/tex]. After completing the rise and fall cycle, the function cuts back to the x axis at [tex]x = 4\pi[/tex].

Then the period [tex]T = 4\pi[/tex].

Second, look at the orange graph when b = 2

Identify a point where the orange chart cuts the x-axis. For example at [tex]x = 0[/tex]. After completing the rise and fall cycle, the function cuts back to the x-axis at [tex]x = \pi[/tex].

Then the period [tex]T = \pi[/tex].

We also know that the period of a sinusoidal function is defined as [tex]T(b) = \frac{2\pi}{b}[/tex]

So:

[tex]T(0.5) = \frac{2\pi}{0.5} = 4\pi\\\\T(2) = \frac{2\pi}{2} = \pi[/tex]

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 5 to 8. If there were 3585 yes votes, what was the total number of votes?

Answers

Answer: 9321 votes

Step-by-step explanation:

1- You can express the ratio as following:

[tex]5:8[/tex] or [tex]\frac{5}{8}[/tex]

2- Let's call the number of  no votes "N"

3- Therefore, if there were 3585 yes votes, then you can write the following expression to calculate the number of  no votes:

[tex]\frac{5}{8}=\frac{3585}{N}\\\\N=\frac{3585*8}{5}\\\\N=5736[/tex]

4- Then, the total number of votes is:

[tex]t=3585votes+5736votes=9321votes[/tex]

Answer:

9321

Step-by-step explanation:

We can simply make a ratio (fraction) to solve this. Let total number of  NO votes be N. Shown below is the ratio:

[tex]\frac{YesVotes}{NoVotes}=\frac{5}{8}=\frac{3585}{N}[/tex]

Now we can cross multiply and solve for N:

[tex]\frac{5}{8}=\frac{3585}{N}\\5N=8*3585\\5N=28,680\\N=\frac{28680}{5}=5736[/tex]

Hence, number of NO votes is 5736.

To get TOTAL number of votes, we add number of yes votes (3585) to that of number of no votes (5736).

Total votes = 3585 + 5736 = 9321

Write the slope-intercept form of the equation that passes through the point (3,6) and is parallel to the line y = 5x - 5

Answers

Answer:

the slope-intercept form:

y = 5x - 9

Step-by-step explanation:

y = 5x - 5, this line has slope = 5

parallel line, slope is the same so slope of the parallel = 5

equation

y - 6 = 5(x - 3)

y - 6 = 5x - 15

y = 5x - 9   <------the slope-intercept form

Answer: [tex]y=5x-9[/tex]

Step-by-step explanation:

The slope-intercept form of a equation of the line is:

[tex]y=mx+b[/tex]

Where m is the slope and b the y-intercept-

If the lines are parallel then they have the same slope:

m=5

Find b substitutin the point and the slope into the equation and solving for b:

[tex]6=3*5+b\\b=-9[/tex]

Then the equation is:

[tex]y=5x-9[/tex]
