Hope this helps!

Answer:

A and B

Step-by-step explanation:

Answer:

B. 3/2

Step-by-step explanation:

If f(x) and [tex]f^{-1}(x)[/tex] are inverse, that means that if we switch the x and y for f(x) and solve for y, we will get the inverse function.

Knowing that f(x) = 2x + 5, let's write this as y = 2x + 5 and switch the x and y:

x = 2y + 5

Now, solve for y:

x = 2y + 5

x - 5 = 2y

y = (x - 5)/2

That's the [tex]f^{-1}(x)[/tex] function: [tex]f^{-1}(x)=\frac{x-5}{2}[/tex]

Plug in 8 for x:

[tex]f^{-1}(x)=\frac{x-5}{2}[/tex]

[tex]f^{-1}(8)=\frac{8-5}{2}=3/2[/tex]

The answer is thus B.

Answer:

B. 3/2

Step-by-step explanation:

When we have inverses, the input to one is the output of the other

f(x) = 2x+5

y = 2x+5

We want to find

f^ -1 (8)

So x becomes y and y becomes x in the inverse

That means we want y = 8 in the original function

8 = 2x+5

Subtract 5 from each side

8-5 = 2x+5-5

3 = 2x

Divide by 2

3/2 =x

This means the solution to

f^ -1 (8)  = 3/2

Irrational

Step-by-step explanation:

Irrational numbers have decimal expansions that neither terminate not repeatable

π = 3.1428.........

-4π =-12.5714..........

Answer:

D. Irrational

Step-by-step explanation:

First, let's calculate what -4π is.

-4π= -4*π= -12.5663706143....

Now, let's analyze the answer choices.

Whole numbers are the numbers 1,2,3,4,5...

Integers are like whole numbers, but negatives are also included.

Rational numbers are numbers that can be written as fractions, or have repeating/terminating decimals.

Irrational numbers cannot be written as fractions, do not repeat and do not terminate.

-12.5663706143... doesn't repeat or terminate, therefore it must be irrational.

Answer:

11.) 10w^2 + 43w + 21.

12.) -15y^2 - 2y + 8

Check the explanation for details

Step-by-step explanation:

11.) You are meant to multiply each row by both columns. For instance, multiply 5w by 2w and 7 you will get 10 w^2 and 35 w

Also, multiply 3 by both 2w and 7 you will get 6w and 21. Therefore,

Expansion of ( 5w + 3 )( 2w + 7 ) will produce 10w^2 + 37w + 6w + 21

= 10w^2 + 43w + 21.

12.) Repeat the same process by multiplying row by column.

Multiply -3y by 5y and 4 you will get -15y^2 and -12y.

Also, multiply 2 by same 5y and 4. You will get 10y and 8

Therefore, the expansion of

( -3y + 2 )( 5y + 4 ) will be

-15y^2 - 12y + 10y + 8

-15y^2 - 2y + 8

The question is a True or False question

Answer:

True

Step-by-step explanation:

Given

5 ≤ x ≤ 8

Required

Is [5,8] the interval of the given range?

The interval given shows that the range of x begins at 5 and ends 8.

Start by splitting the interval to different inequalities.

1. 5 ≤ x

This implies that 5 is less than or EQUAL TO x;

The keyword needed here is EQUAL TO;

The fact that the inequality gives room for EQUALITY (=) means that the interval begins exactly at 5

2. x ≤ 8

This implies that x is less than or EQUAL TO 8;

Similarly, the keyword needed here is EQUAL TO;

The fact that this inequality gives room for EQUALITY (=) means that the interval ends exactly at 8

So, this implies that the range of values of 5 ≤ x ≤ 8 is 5, 6, 7, 8

And can be represented with [5,8]

So, the statement is true.

Answer:

8:17

Step-by-step explanation:

With ratios, you're relating one piece of information to another. Here, it's asking you to relate the shortest leg (8 in.) to the hypotenuse (17 in.). A ratio is formed by putting a semi-colon (:) between your relations, so your answer to this question will be 8:17.

This question is not correctly written

Correct Question

A sector whose central angle measures 120° has an area of 12 square inches. What is the radius of the circle?

Answer:

Radius of the circle = 3.3851375013 inches

Approximately to one decimal place, radius of the circle = 3.4 inches

Step-by-step explanation:

The formula for the area of a sector is given as:

Area of a sector = θ × π/360 × r²

θ = Central angle in degrees = 120°

Area of a sector = 12 in²

12 = (120° × π)/360 × r²

r² = 12 ÷(120° × π)/360

r² = 12 ÷ 1.0471975512

r² = 11.459178217

r = √11.459178217

r = 3.3851375013 inches

Approximately to one decimal place, radius of the circle = 3.4 inches

Split up the interval [0, 2] into n equally spaced subintervals:

[tex]\left[0,\dfrac2n\right],\left[\dfrac2n,\dfrac4n\right],\left[\dfrac4n,\dfrac6n\right],\ldots,\left[\dfrac{2(n-1)}n,2\right][/tex]

Let's use the right endpoints as our sampling points; they are given by the arithmetic sequence,

[tex]r_i=\dfrac{2i}n[/tex]

where [tex]1\le i\le n[/tex]. Each interval has length [tex]\Delta x_i=\frac{2-0}n=\frac2n[/tex].

At these sampling points, the function takes on values of

[tex]f(r_i)=7{r_i}^3=7\left(\dfrac{2i}n\right)^3=\dfrac{56i^3}{n^3}[/tex]

We approximate the integral with the Riemann sum:

[tex]\displaystyle\sum_{i=1}^nf(r_i)\Delta x_i=\frac{112}n\sum_{i=1}^ni^3[/tex]

Recall that

[tex]\displaystyle\sum_{i=1}^ni^3=\frac{n^2(n+1)^2}4[/tex]

so that the sum reduces to

[tex]\displaystyle\sum_{i=1}^nf(r_i)\Delta x_i=\frac{28n^2(n+1)^2}{n^4}[/tex]

Take the limit as n approaches infinity, and the Riemann sum converges to the value of the integral:

[tex]\displaystyle\int_0^27x^3\,\mathrm dx=\lim_{n\to\infty}\frac{28n^2(n+1)^2}{n^4}=\boxed{28}[/tex]

Just to check:

[tex]\displaystyle\int_0^27x^3\,\mathrm dx=\frac{7x^4}4\bigg|_0^2=\frac{7\cdot2^4}4=28[/tex]

Answer: 24 different words

Step-by-step explanation:

Answer:

C. 41

Step-by-step explanation:

We want to find the number of odd integers from 10 to 51.

The first odd integer from 10 to 51 is 11; the second is 13; the third is 15; and so on until 51. So, our list looks like this:

11, 13, 15, ... , 51

We need to figure out how many numbers there are. Let's add 1 to all of them:

11 + 1, 13 + 1, 15 + 1, ... 51 + 1

12, 14, 16, ... , 52

Now, let's divide by 2:

12/2, 14/2, 16/2, ... 52/2

6, 7, 8, ... , 26

Finally, subtract 5 from them:

6 - 5, 7 - 5, 8 - 5, ... , 26 - 5

1, 2, 3, ... , 21

There are 21 odd integers, so x = 21.

The even integers from 10 to 51 start with 12, 14. They end with 50. So, we have:

12, 14, ... 50

Let's use a similar method as above. Divide by 2:

12/2, 14/2, ... , 50/2

6, 7, ... , 25

Subtract 5:

6 - 5, 7 - 5, ... , 25 - 5

1, 2, 3, ... , 20

There are 20 even integers, so y = 20.

Then, x + y = 21 + 20 = 41.

The answer is thus C.

yellow would be B

orange would be D

I hope this helps!!!!

Answer:

a) point B

b) point D

Step-by-step explanation:

a) since there are 3 yellow sweets out of a total of ten, the probability of choosing a yellow sweet is 3/10 = 0.3 Therefore point B shows that number on the probability scale.

b) Since there are no orange sweets in the bag, the chances of a selecting sweet not being orange is ten out of ten (10/10 = 1 (for sure the sweet will not be orange). Therefore, point D shows such probability.

Answer:

x = 4y+28

Step-by-step explanation:

x/4 -7 = y

Solve for x

Add 7 to each side

x/4  -7+7 = y+7

x/4 = (y+7)

Multiply each side by 4

x/4*4 = 4(y+7)

x = 4y+28

Answer: X = 4y + 28

Step-by-step explanation: Our first step will be to solve for x.

To do this, we first add 7 to both sides.

This gives us x/4 = y + 7.

Now we want to multiply each side of the equation by 4.

So we get x/4(4) = 4(y + 7).

On the right, distribute the 4 through the parenthses!

Simplifying from here, we get x = 4y + 28.

So this is our final answer.

Answer:

The cost of one large drink is $1.50.

(13.5-10) + 4 = (7.5 ÷ 5) = $1.50

Step-by-step explanation:

The first step is to minus the $10.00 from the $13.50, which gives us $3.50.

13.5 - 10

We've done this because the pizza is irrelevant to what we're trying to figure out, so we subtract the price of the food, which as we already know is $10, to isolate the price of the 5 drinks to make it easier to find the price of just one.

Once we've done that, we're going to add on the $4.00 they got discounted to the $3.50 in order to find the original price of the drinks without using the gift certificate.

(13.5 - 10) + 4

This gives us $7.50, or the price of 5 large drinks. But we're only looking for the price of one. So we're going to divide the 7.50 by the total number of drinks ordered.

(13.5-10) + 4 = (7.5 ÷ 5)

This gives us 1.5, or $1.50.

(13.5-10) + 4 = (7.5 ÷ 5) = $1.50

Answer:

d) Vessels that are any length

Step-by-step explanation:

MSDs can be defined fully as Marine

Sanitation Devices. Marine Sanitation Devices are devices in the shape of a tank that is used for storing and treating of waste materials when marine vessels e.g. boats are on sea.

It is very inappropriate, unhygienic and illegal to dump waste materials at sea because this could cause harm to the aquatic life forms at sea. This is the reason why a marine sanitation device is required.

There are three types of MSDs

a) Type I

b) Type II

c) Type III

Marine Sanitation Devices are classified into types based on

1) The length of the vessels in which that are installed on.

2. The method for treating or breaking down the waste materials in the devices.

In the question above, the TYPE III MARINE SANITATION DEVICES CAN BE INSTALLED ON VESSELS THAT ARE ANY LENGTH.

This is because the Type III Marine Sanitation Devices are devices that stops the discharge or expelling of waste materials e.g sewage (whether have been treated or untreated) into the sea.

These type III MSDs is consists mainly of a tank used for holding and storing the waste materials. In this tank as well as other types of methods used for treating the waste which the includes incineration, composting e.t.c. may be found in the tank as well. Even after treating the waste in a Type III MSD, it can't be expelled into the sea , it can only be transferred to the Water Treatment Facility when the marine vessel comes to the seaport for more treatment and appropriate disposal.

▹ Answer

The correct answer is C. x = 375 sq ft y = 6,300 sq ft

▹ Step-by-Step Explanation

The ratio is 1:15 so...

x → 5,625

(Divide 5,625 by 15 since we have to find the x value meaning we have to do the inverse operation)

5,625 ÷ 15 = 375

420 → y

(Multiply 420 by 15 since we have to find the y value meaning we have to do multiplication)

420 × 15 = 6,300
