Which of the following are solutions to the equation below? 6x 2 - 2x + 36 = 5x 2 + 10x

Answer:

a=3

Step-by-step explanation:

This should be very simple, just substitute xy and y for 5 and 7 respectively, so 5a-2*7=1, or 5a-14=1, or 5a=15, if we divide both sides by 5, we get a=3

Answer:

A=3 5a-14=1

Step-by-step explanation:

Add 14 to both sides then divide 5 and 15 to get 3

if the given point satisfies this equation then it would be its solution

(-1)=2(5)-11

-1=10-1

-1=-1

lHS=RHS

Hence (/,-1) is the solution of y=2x-11

In an acute triangle ABC Inscribed angles in a circle with another triangle MNP formed by the intersections of tangents to the circle at points A, B, and C, the angles of triangle MNP are the sum of the opposite angles of triangle ABC. Therefore, ∠M = α + γ, ∠N = β + α, and ∠P = γ + β.

The question is about an acute triangle ABC inscribed in a circle and another triangle MNP formed by the intersections of tangents to the circle at points A, B, and C.

From the properties of circle and geometry, in such a scenario, the angles of triangle MNP correspond to sum of the opposite angles of triangle ABC.

The measures of angles in △MNP are as follows:

∠M = α + γ

∠N = β + α

∠P = γ + β

This relation comes from the fact that the exterior angle of a triangle is equal to the sum of the opposite interior angles.

Answer:

This may be misleading because it leaves room for doubt.

Step-by-step explanation:

If they're only saying that 80% use the toothpaste, that is saying that there is 20% who don't like it.

Final answer:

A commercial claiming "80% of dentists use this toothpaste" may be misleading due to lack of context, potential selection bias, and vagueness surrounding the term 'use.' Historical instances, like deceptive advertising by Colgate-Palmolive in the 1950s, alert consumers to be cautious of such claims.

Explanation:

A commercial claiming that "80% of dentists use this toothpaste" might be misleading because it does not provide a full context. Without additional information, such a statement can create false impressions. For instance, the sample size could be too small or not representative of the general population of dentists. The selection criteria for the dentists might be biased towards those who prefer the product or are somehow affiliated with the toothpaste's manufacturer. Furthermore, the term "use" is vague and could simply mean the dentists have tried the product rather than regularly using it. It is also important to question whether dentists recommend the toothpaste to their patients or if their usage is based on personal preference only.

As history has shown with the deceptive advertising practices of the 1950s, like those of Colgate-Palmolive with their Rapid Shave product, companies have sometimes engaged in advertising that misrepresented the effectiveness of their products. Therefore, it's essential for consumers to be wary of such claims and seek more information before making a purchase decision based on such endorsements.

To find the probability of not rolling factors of 6 on both six-sided dice, multiply the individual probabilities of rolling a 4 or 5 on each die. The probability is 1/9.

The factors of 6 are 1, 2, 3, and 6. Therefore, the outcomes that are not factors of 6 are 4 and 5.

Since each die has six faces, the total number of possible outcomes when rolling two dice is 6 x 6 = 36.

Of these 36 possible outcomes, we need to count how many do not involve factors of 6. For each die rolled independently, we have 2 outcomes that are not factors of 6: {4, 5}.

So, we need to calculate the product of these individual probabilities to find the probability of both dice showing a non-factor of 6.

For a single die, the probability of rolling a non-factor of 6 (either a 4 or a 5) is 2/6 or 1/3, since we have 2 favorable outcomes out of 6 possible ones.

To find the probability for both dice, we multiply these individual probabilities:

Probability of not rolling a factor of 6 on both dice = (1/3) x (1/3) = 1/9.

This is the product rule in probability, which tells us that the probability of two independent events both happening is the product of their individual probabilities.

Therefore, the probability of not rolling a factor of 6 on both dice is 1/9.

Answer:   There are two points of intersection (2, 4) and (-4, -2)

Step-by-step explanation:

x - y + 2 = 0     →       x = y - 2

Use Substitution Method:

x² + y² = 20

(y - 2)² + y² = 20              replaced x with (y - 2)

y² - 4y + 4 + y² = 20        expanded (y - 2)²

2y² - 4y + 4 = 20             added like terms

2y² - 4y - 16 = 0               subtracted 20 from both sides

y² - 2y - 8 = 0                  divided both sides by 2

(y - 4)(y + 2) = 0               factored

y - 4 = 0    and      y + 2 = 0       applied Zero Product Property

y = 4        and       y = -2

Input the y-values into x = y - 2 to solve for x.

y = 4;   x = 4 - 2                      y = -2;    x = -2 - 2

           x = 2                                         x = -4

      (2, 4)                                         (-4, -2)

The area of the L-shaped figure formed is 225 square inches.

To find the area of the L-shaped figure formed after cutting corners, start by calculating the area of the square from which the corners were removed.

The larger square has sides of length 15 inches, so its area is 15 x 15 = 225

When you cut corners of 9 inches by 9 inches from each corner of the larger square, you effectively create a smaller square. Since each side of the smaller square is 9 inches shorter than the larger square, its side length is -

15 - 2 x 9

= - 3

However, a negative side length is not possible, so we adjust it to zero. This implies that there's no square left after cutting off such large corners.

The area of the L-shaped figure is the difference between the area of the larger square and the area of the smaller square:

Area of L-shaped figure=Area of larger square−Area of smaller square

= 225 - 0

= 225

Thus, the area of the L-shaped figure formed is 225 square inches.

Answer:

C. 45 degrees.

Step-by-step explanation:

The degree of the entire circle is 360 degrees, and the circle is divided into 8 equal sections, therefore x = 360/8 = 45 degrees.

The central angle of a regular octagon is computed by dividing the total degrees in the circle (360 degrees) by the number of sides in the octagon (8). Hence, the value of 'x' is 45 degrees.

The question is asking for the measure of 'x', which represents the angle in the center of the octagonal umbrella. To solve this, we need to remember that the total degrees in a circle (or in this case, an octagon) is 360 degrees. As a regular octagon consists of 8 equal angles, we simply divide 360 by 8 to find the measure of each angle. Therefore, 'x' equals to 45 degrees. This corresponds to option C.

The volume of a hemisphere with a radius of 5 inches is calculated by first determining the volume of a full sphere using the formula V = (4/3)πr³, and then dividing that by 2. The final volume of the hemisphere is 261.7994 cubic inches.

Volume of a Hemisphere

The question involves finding the volume of a hemisphere, which is half of a sphere, with a given radius of 5 inches. First, we would calculate the volume of a full sphere using the formula V = (4/3)πr³, and then divide that by 2 to get the hemisphere volume. Therefore, for a sphere with a radius of 5 inches:

Volume of the sphere, V = (4/3)π × 5³.

Volume of the hemisphere = V/2.

After performing the calculations:

Volume of the sphere, V = (4/3)π × 125 = 523.5988 cubic inches.

Volume of the hemisphere = 261.7994 cubic inches.

Answer:

2.24

Step-by-step explanation:

5 is not a perfect square and therefore its square root is not an integer.

it is a decimal which can partly be presented as 2.236068. the digits after the decimal point occupy the following decimal spaces

2-tenths

3-hundredths

6-thousandths.

If the digit in the thousandths position is 5 or greater then we add one to the digit in the hundredths position to get the nearest hundredth while if it is less than 5 we truncate at the hundredth position and retain the digit at this position as the nearest hundredth.

in this question, the digit in the thousandth position is 6 thus we add 1 to the digit in the hundredth position that is,3 to get 4

therefore the square root of 5 to the nearest hundredth is 2.24

[tex]d>3[/tex] or [tex]d<-3[/tex]

Step-by-step explanation:

The absolute value is a function that transforms any value x into a positive number.

Therefore, for the function [tex]f(x) = |x|[/tex]  x> 0 for all real numbers.

Then the inequation:

[tex]|d|> 3[/tex] has two cases

[tex](d)[/tex]    if [tex]d>0[/tex]  (i)

[tex]-(d)[/tex]    if [tex]d< 0[/tex] (ii)

We solve the case (i)

[tex]d> 3[/tex]

We solve the case (ii)

[tex]-d>3\\d < -3[/tex]

Then the solution is:

[tex]d>3[/tex] or [tex]d<-3[/tex]

Answer:

Last choice is the correct graph.

Step-by-step explanation:

We have been given inequality [tex]|d|>3[/tex]. Now we need to find out which of the given number lines shows the correct solution set for [tex]|d|>3[/tex].

We know that [tex]|x|>a[/tex] can be broken into :

[tex]x>+a[/tex] or [tex]x<-a[/tex]

Same way we can break [tex]|d|>3[/tex] into two parts as:

[tex]d>+3[/tex] or [tex]d<-3[/tex]

Since it has only < symbol but not equal so we make an open circle at both +3 and -3.

Hence last choice is the correct graph.

Answer:

g(f(0)) = 6

Step-by-step explanation:

Evaluate f(0 ) and substitute this value into g(x)

f(0) = 0² = 0 and

g(0) = 0 + 6 = 6

⇒ g(f(0)) = 6

The value of g(f(0)) is 6.

If two functions f(x), g(x) are present , then (f o g) of x is also known as a composite function and it is mathematically denoted as f(g(x)) or (f ∘ g)(x). It means that x = g(x) should be substituted in f(x). It is an operation that combines two functions to form another new function.

Given , f(x) = [tex]x^{2}[/tex]  and  g(x) = x + 6

We have to find g(f(0)).

To get the value of this composite function g(f(x)), we first have to find the value of f(x) at the given value x = 0 and then substitute the value of f(x) into g(x).

⇒ f(0) = 0.

∴ g(f(0)) = g(0) = 0 + 6 = 6.

Therefore we have the value of g(f(0)) as 6.

To find the median of a distribution, we first need to arrange the data in ascending order. Then, if the number of data points is odd, the median is the middle value. If the number of data points is even, the median is the average of the two middle values.

Given the distribution: 24, 26, 26, 28, 29, 31, 33, 35, 37, 38, 40, 42, 43, 46, 48

Arranging the data in ascending order: 24, 26, 26, 28, 29, 31, 33, 35, 37, 38, 40, 42, 43, 46, 48

There are 15 data points, which is an odd number. The middle value is the 8th value, which is 35.

Therefore, the median of the given distribution is:

OE. 35

The median of the given distribution is the ninth number in the ordered set, which is 37.

To find the median of the given distribution, you will first need to order the data from smallest to largest, which has been done. The data set consists of 17 values, so the median will be the value in the middle position, which is the 9th value when the data is ordered. Since the data set is already in ascending order, you count nine values from the start, and the 9th value is the median.

The sequence of numbers is: 24, 26, 26, 28, 29, 31, 33, 35, 37, 38, 40, 42, 43, 46, 48, 55, 56.

Answer:

right

Step-by-step explanation:

You would move it towards the right because that adds a place value while moving it to the left takes away a place value.

When you multiply a number by powers of 10, the decimal point moves to the right as many places as there are zeros in the multiplier. For example, multiplying 1.2 by 10 gives 12, because the decimal point moves one place to the right.

In mathematics, when you multiply a number by 10, 100, 1,000, and so forth (powers of 10), you move the decimal point to the right as many places as there are zeros in the multiplier. This is because you are increasing the value of the number by a factor of 10 for each move to the right.

For instance, if you multiply 1.2 by 10, the result is 12. The decimal point has moved one place to the right because there is one zero in 10. If you multiply 1.2 by 1,000, the result is 1,200. The decimal point has moved three places to the right because there are three zeros in 1,000.

This understanding makes it easier to handle multiplication of numbers by powers of 10. But remember, this only applies when multiplying. When dividing, the decimal point moves to the left.

Answer:  y = x

Step-by-step explanation:

First, find the point where 5x - 2y + 3 and 4x - 3y + 1 intersect using the Elimination Method.

5x - 2y + 3 = 0  →  3(5x - 2y + 3 = 0)  →  15x - 6y + 9 = 0

4x - 3y + 1 = 0   → -2(4x - 3y + 1 = 0)  →   -8x + 6y - 2 = 0

                                                                 7x         + 7 = 0

                                                                 7x               = -7

                                                                   x               = -1

5x - 2y + 3 = 0

5(-1) - 2y + 3 = 0

-5 - 2y + 3 = 0

    -2y  - 2 = 0

    -2y        = 2

        y        = -1

(-1, -1)

Next, find the point where x = y and x = 3y + 4 intersect using the Substitution Method.

x = y

x = 3y + 4    →    y = 3y + 4

                      -2y = 4

                         y = -2

x = y

x = -2

(-2, -2)

Now, find the line that passes through (-1, -1) and (-2, -2) using the Point-Slope formula.  (x₁, y₁) = (-1, -1)  and m = 1

y - y₁ = m(x - x₁)

y + 1 = 1(x + 1)
