Answer:

I believe that it is C.

Step-by-step explanation:

Amanda's speed is 9 mph because 18 divided by 2 is 9.

Marcos speed is 8 mph because you can work backwards from the graph from the second point of (2, 16) to (1, 8) and find the difference of 1, and 8.

The slope is therefore 8.

Amanda's speed is 9 mph and Marco's speed is 8 mph. I think you know the answer from the previous statement.

RSB [31]

Ok so let me help you like this: We need to understand first that The basketball has a higher speed, that means that the tennis ball will never catch up. so what we need to use is the formula
Vr=Vb--Vt
=0.5-0.25=0.25
So the speed is 0.25m/s
Hope this is useful

find the balance in the account. $2,400 principal earning 2%, compounded annually, after 7 years $2,736.00 $2,756.85 $307,200.00

Alex17521 [72]

The future worth (F) of the current investment (P) that has an interest (i) that is compounded annually is calculated through,
F = P x (1 + i)^n
where n is the number of compounding period. Substituting the given values,
F = ($2,400) x ( 1+ 0.02)^7 = $2,756.85
Thus, the future worth is approximately $2,756.85. The answer is the second choice.

A rectangular sheet of metal has identical squares cut from each corner. The sheet is then bent along the dotted lines to form a

Reika [66]

The correct answer is:

3 inches.

Explanation:

We will use the Rational Roots Theorem to solve this.

First we can divide both sides of the equation by 4 in order to simplify it:

$\frac{4x^3-72x^2+320x}{4}=\frac{420}[4} \\ \\x^3-18x^2+80=105$

In order to solve this, we want the polynomial set equal to 0. To do this, subtract 105 from both sides:

$x^3-18x^2+80x-105=105-105 \\x^3-18x^2+80x-105=0$

The Rational Roots Theorem says that if p/q is a root of the polynomial, then p is a factor of the constant term and q is a factor of the leading coefficient. The constant term is -105. Drawing a factor tree, we find that the factors of this number are 1, -1, 3, -3, 5, -5, 7, -5, 15, -15, 21, -21. The leading coefficient is 1; its only factor is 1. This means p/q must be a whole number, and can be any of the factors of 105.

Using synthetic division, we try 1 in the box:

1 | 1 -18 80 -105

_______ 1__ -17___63__

1 -17 63 -42

Since there is a remainder, this is not a root. Trying -1,

-1 | 1 -18 80 -105

_______-1__ 19 _-99_

1 -19 99 -204

This is not a root; in fact, it shows us that none of the negatives will be a factor, as the absolute values increase as we complete the synthetic division.

Trying 3,

3 | 1 -18 80 -105

________3__-45___105_

1 -15 35 0

Since there is no remainder, 3 is a root, and is the answer we are looking for.
