Can someone please help me with this?

What is the volume of this sphere?

Answer:

Step-by-step explanation:

basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.

first, you need to factor out the equation.

start with the original equation.

V=4x^3+10x^2+4x

factored form:

V= 2x(2x^2+5x+2)

next, you're going to want to plug in the values.

the answer asks for x=4, but you should do both.

v=2(3)(2(3)^2+5(3)+2)

do not forget to do the exponents before!

v=6(18+15+2)

v=6(35)

v=210 ft^2

that's the answer for if x was equal to 3.

V= 2x(2x^2+5x+2)

don't forget to write the original equation first.

V=2(4)(2(4)^2+5(4)+2)

V=8(36+20+2)

Answer:

Question 1: square root of 109

Question 2: 2, 1, 1

Question 3: True

Step-by-step explanation:

The square root of 109 is about 10.4 which is greater than 5 and 9.

In the equation a^2 + b^2 = c^2, a and b represent the legs of a triangle and c represents the hypotenuse.

The Pythagorean Theorem states that For all right triangles the square of the hypotenuse is equal to the square of both sides. (a^2 + b^2 = c^2)

Answer:

a

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

First, (3/2) is greater than 1, which therefore eliminates A and D.

Second, you must determine if the triangle gets larger or smaller. Lets suppose that X = 2 and Y = 3. If we were to multiply both of these values by (3/2), our points would change to X = 3 and Y = 4.5

Since there was an increase, this means that the triangle was larger.

This leaves B as the answer.

Remember: Any scale value greater than 1 is an enlargement, as proven by the hypothetical.

Answer: Mean Absolute Deviation Calculator

Instructions

This calculator computes the mean absolute deviation from a data set:

You do not need to specify whether the data is for an entire population or from a sample. Just type or paste all observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. Press the "Submit Data" button to perform the computation. To clear the calculator, press "Reset".

What is the mean absolute deviation

The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out.

Mean absolute deviation formula

This calculator uses the following formula for calculating the mean absolute deviation:

$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

Answer:

A) -3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

2x² + 4x - 3

x = -2

Step 2: Evaluate

Answer:

[tex]\huge\boxed{\text{A) -3}}[/tex]

Step-by-step explanation:

To find the value of this equation when [tex]x=-2[/tex], we can substitute this value inside the equation and use PEMDAS to successfully find the value.

With the expression of [tex]2x^2+4x-3[/tex], let's substitute -2 in as x.

Now let's follow PEMDAS to solve this equation.

PEMDAS states that when solving an expression/equation, the order we must follow is

We can now solve for this.

We see that exponents come before multiply and dividing. Therefore:

So the value of our first term is 8.

Our second term will be [tex]4 \cdot -2 = -8[/tex], and our last term will remain -3.

Adding these values together:

[tex]8 - 8 - 3 = -3[/tex]

Therefore, the value of this expression when x = -2 is -3.

Answer:

$8,900

Step-by-step explanation:

You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.

Here i = $8,000*0.075*1.5 (representing 18 months)

         i + $900

At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.

Step-by-step explanation:

Answer:

15 Rolls.

Step-by-step explanation:

This problem is one that can be solved simply by dividing.

Take 5, and divide that by 1/3.

However, you can't just do this. The way I did it was by turning 5 into 5/1. Then, Multiply by the reciprocal, which would be 5 x 3, which equals 15.

Answer:

last one because theres no slope just a y intercept

Answer:

No

Step-by-step explanation:

Here's what's going on: some person buying their furniture sees this sofa and it's $1200. That person sees theres a 1/3 off sale! They're happy and buy their sofa with a 20% off discount they got.

Now we have to find out  if they should use the 20% off discount before or after adding the 1/3 off sale.

The answer is, they're both the same.

Say they add the 1/3 off sale discount and then use their 20% off discount. Find the 1/3 off sale: 1200 divided by 3 (because fractions are division problems) = 400. 20% of 400: 400 x 0.2 = 80. It's not just 80, because it's not an "only pay 20%" discount. 400 - 80 = 320. They'd pay $320 with this method.

This shows that using the 20% discount after the 1/3 off sale the customer spends $320.

Now let's calculate what happens if they use the discount after the 1/3 off sale. 20% of 1200: 1200 x 0.2 = 240. 1200 - 240 = 960. Now adding the 1/3 off sale: 960 divided by 3 = 320. They'd also pay $320 with this method.

If it's a short answer, you could just write something like, "No, both methods end up with the sales associate paying $320."

Hope this helps!
