What are the zeros of A(x) = x(x-7)?
O A. x = 0 only
O B. X = 7 only
O c. x = 0 and x = -7
O D. x = 0 and x = 7

Answers

Answer 1

Answer:

x=0   x=7

Step-by-step explanation:

A(x) = x(x-7)

Set equal to zero

x(x-7) =0

Using the zero product property

x=0     x-7 =0

x=0   x=7

The distance between the elementary school and the middle school is 4 miles. On the map, the two locations are One-half inch apart. What is the scale of the map?
1 inch = 8 miles
1 inch = StartFraction 1 over 8 EndFraction mile
One-half inch = 1 mile
4 inches = 1 mile

Answers

1 inch = 8 miles

1/2in + 1/2in = 1in

4 + 4 = 8

1 Inch = 8 miles

I know this because half of 8 is 4 and that is the distance between the locations

In a set of 1,000 integers from 1 to 1,000, an integer chosen at random on a single trial should be an integer from 1 to 25 about 25 out of every 1,000 trials, or one out of every 40 integers selected. A sample of 5 integers selected is shown. Does this sample represent the general rule for picking an integer from 1 to 25 in the population of integers from 1 to 1,000?


A. Yes - the sample is representative of the expected number of integers from 1 to 25 in a sample of 5 integers, which would be none or zero.

B. No - the sample is not representative of the expected number of integers from 1 to 25 in a sample of 5 integers, which would be at least 10.

How can I find the cube root of 64?

Answers

Answer:

4

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

Write an equation of the line that passes through each pair of points.
(0, 7), (0, −8)

Answers

Answer:

x = 0

Step-by-step explanation:

linear equation y = mx + b, where m is the slope and b is the y intercept when x is 0.

m = change in y/change in x = -8-7/0 = undefine

so line is vertical at x = 0

The slope of m is undefined, A line with zero slope is perfectly flat in the horizontal direction.

We have the value of two points:

(0, 7), (0, −8)

Let's find the slope of this line. The formula for slope is:

\(\frac{y_2-y_1}{x_2-x_1}\)

Plug all the values in above formula:

=> \(\frac{-8-7}{0-0}\)

m = undefined

A line with zero slope is perfectly flat in the horizontal direction. No matter what value of x you have, you get the same y-value. It does not increase or decrease.

Step-by-step explanation:

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).

Answers

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Combine like terms to simplify the expression.

3y-10x+5x-6y-7+8

Answers

Answer: -5x - 3y + 1

Step-by-step explanation:

When you get a question that asks you to combine like terms, arrange the x terms together, the y terms together, and the numbers together. Be sure to keep the + and - signs in front of each term.

-10x + 5x + 3y - 6y - 7 + 8

Once the like terms are together, you can add and subtract.

-10x + 5x = -5x

+3y - 6y = - 3y

-7 + 8 = +1

Put all the terms together to form the simplified expression.

-5x - 3y + 1

3y-10x+5x-6y-7+8
3y-5x-6y+1
-3y-5x+1
