Answer:

f(x)^-1 = 1/2x +3

Step-by-step explanation:

f(x) = 2x-6

y =2x-6

Exchange x and y and solve for y

x = 2y -6

Add 6 to each side

x+6 = 2y

Divide by 2

(x+6)/2 = 2y/2

(x+6)/2 =y

1/2x +3 =y

This is the inverse of f(x)

Step-by-step explanation:

As you can see you have to find out what equals 4 AND what equals 12 and to make sure:

Do 2x2 is 4 because 4 times 1 yes but 6 times 1 is not 12 its 26 therefore C is INCORRECT

A Is Also wrong because 6 x 1 is 6 sure yes 4 x 1 is for but they both have to be equal so A is INCORRECT

And Is wrong because 8 x 4 is 32 but we are looking for what equals 4 not 32 and 6 x 8 is 48 we are looking for a 12 so D is INCORRECT

Now what leaves is B well 2 x 2 =4 and 2 x 6 = 12 Therefore B is Correct! Another way you can do this is to divide 12 ÷ 6 = 2 and 4 ÷ 2 = 2

Answer:

The short leg is 7 because half of 14 is 7 and the hypotenuse is always twice as long as the shortest one.

The required short leg is 7inches.

Given that,

Hypotenuse = 14 inches,

In triangle 30-60-90

We have to determine,

By using figure find the short leg.

According to the question,

A 30-60-90 triangle is a special right triangle whose angles are 30º, 60º, and 90º.

The triangle is special because its side lengths are always in the ratio of 1: √3:2.

The 30-60-90 triangle rule is for finding the the lengths of two sides when one side is given.

The shorter side is opposite the 30 degree angle, the longer side is opposite the 60 degree angle, and the hypotenuse is opposite the 90 degree angle.

Therefore,

The hypotenuse is always twice as long as the shortest one.

Where, Hypotenuse = 14inches

Then,

[tex]Hypotenuse = 2 \times short \ leg \\\\14 = 2 \times short \ leg\\\\short\ leg = \dfrac{14}{2}\\\\short \ leg = 7[/tex]

Hence, The required short leg is 7inches.

There are 13 shoppers aged 20 or older. Calculated by summing frequencies of age groups 20-24 through 35-39. Answer: (c) 13.

Of course, I'm happy to help! To find out how many shoppers are at least 20 years old, we need to add up the frequencies of the age groups that are 20 years old and older. Here are the steps:

1. Identify the age groups that are 20 years old and older.

2. Add up the frequencies (the number of shoppers) for those age groups.

Let's assume the histogram provides age groups in 5-year intervals, starting from 0 to 4 years old, then 5 to 9 years old, and so on.

Let's look at the age groups that are at least 20 years old:

1. 20-24 years old

2. 25-29 years old

3. 30-34 years old

4. 35-39 years old

5. 40-44 years old

We add up the frequencies for these age groups:

1. Frequency for 20-24 years old: 5

2. Frequency for 25-29 years old: 4

3. Frequency for 30-34 years old: 3

4. Frequency for 35-39 years old: 1

5. Frequency for 40-44 years old: 0 (since it's not specified in the histogram, we assume it's 0)

Adding these frequencies together:

5 + 4 + 3 + 1 + 0 = 13

So, there are 13 shoppers who are at least 20 years old.

The answer is (c) 13.

[tex]S_{\infty}=\frac{80}{3}[/tex]

Step-by-step explanation:

The sum of an infinite geometric series is given by:

[tex]S_{\infty}=\frac{a}{1-r}[/tex],

The given geometric series is

[tex]\sum_{n=1}^{\infty}32(-\frac{1}{5})^{n-1}[/tex]

The constant ratio for this series is

[tex]r=-\frac{1}{5}[/tex]

The first term of the series is [tex]a=32(-\frac{1}{5})^{1-1}=32[/tex]

Answer:

D) y = -2x -3

Step-by-step explanation:

1. Create a slope-intercept equation: y = -5, m = -2, x = 1

y = mx + d -> y = -2x + d -> -5 = -2(1) + d

Solve: -5 = -2 + d --> d = -3

So, the y-intercept is -3. Putting that into our equation gives us y = -2x -3

Answer:

Choices are:

p>30

p<30

p=30

not enough information to tell

Answer is p>30

Step-by-step explanation:

Since there are more boys than girls, there must be at least 9 boys.  Plug into equation:  (b+8) represents number of students.  If they each have at least 2 pencils we would use 2(b+8).  Plugging in  9 for the boys we have: 2(9+8)=?

2(17)=34.  So with the minimum number of boys there would be at least 34 pencils, so the answer is p>30

Final answer:

By calculating that p equals 2 times the sum of boys and girls, and that there are at least 9 boys, we find that p (the total number of pencils) must be greater than 30.

Explanation:

To compare the expressions p and 30, let us first define p as the total number of pencils. Since there must be more boys than girls and there are 8 girls, let b represent the number of boys. We can say that b > 8, since there are more boys than girls.

It's also given that each student has at least 2 pencils. Therefore, the minimum total number of pencils p can be calculated by multiplying the total number of students by 2.

This gives us p = 2(b + 8). Because b > 8, let's substitute the minimum number for boys (9), so p = 2(9 + 8) = 34.

Therefore, p > 30.

Answer:

51.3

Step-by-step explanation:

This is a right triangle (because of the 90° angle).  For any right triangle, you can use the following:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

You can remember this as SOH-CAH-TOA.

We want to find the angle y.  We know that the opposite side is 10 and the adjacent side is 8.  So we can use tangent:

tan y = 10 / 8

y ≈ 51.3°

Answer:

The slope of line parallel to 2x-y = 18 will be 2.

Step-by-step explanation:

Given  

The equation of a line : 2x – y = 18

The standard form of an equation of a line in slope-intercept form is:

y=mx+c

So, we will have to convert the given equation in the standard form.

2x-y=18

-y=-2x+18

-y= -(2x-18)

y=2x-18

The coefficient of x in this form is the slope of the line.

So,

m_1=2

We know that slopes of two parallel lines are equal so if the given line has slope 2, all the lines parallel to this line have slope 2..

For this case, we have by definition, if two lines are parallel then their slopes are equal:

[tex]m_ {1} = m_ {2}[/tex]

We have the following equation:[tex]2x-y = 18[/tex]

We rewrite the equation of the form:

[tex]y = mx + b\\2x-18 = y\\y = 2x-18[/tex]

Thus, a parallel line will have a slope [tex]m_ {2} = 2[/tex]

Answer:

[tex]m_ {2} = 2[/tex]

Answer:

Use the formula for the volume of a cylinder.

[tex]V=\pi r^2h[/tex]

Plug in the height, the radius, and 3.14 for [tex]\pi[/tex].

[tex]V=3.14(15^2)(5) \\ \\ V=3.14(225)(5) \\ \\ V=3.14*1125 \\ \\ V=3532.5[/tex]

If you round that number you'll get [tex]V=3533[/tex].

So the answer is answer choice C.

Answer:

translated left by 2 units

Step-by-step explanation:

Given y = f(x) then

y = f(x ± a) represents a horizontal translation of a units

• If + a then a shift of a units to the left

• If - a then a shift of a units to the right

Hence

g(x) is the graph of f(x) translated 2 units to the left

The function g(x) = (x+2)^2 + 1 is a transformation of the function f(x) = x^2 + 1. It represents a translation of the graph of f(x) to the left by 2 units.

The function g(x) = (x+2)^2 + 1 is a transformation of the function f(x) = x^2 + 1. Particularly, it's a horizontal shift, not a compression or stretching of the graph. By comparing coefficients, we infer that the +2 inside the parentheses on g(x) represents a shift of the graph of f(x) to the left by 2 units. This is because the rules of transformations dictate that h(x) = (x - h)^2, where h represents a shift to the right, and h(x) = (x + h)^2 represents a shift to the left. Therefore, the correct statement is that the graph of g(x) is translated left 2 units compared to the graph of f(x).
