Answer:

Step-by-step explanation:

This is modeled after an exponential function which, at its simplest, is

$y=a(b)^x$ where, for us and in this particular situation, y is the final height, a is the initial height, b is the rate of growth or decline, and x is the number of bounces. We know the initial height is 20, but we need to find the rate of decline. Rewriting the formula to model a rate of decay or decline is

$y=a(1-r)^x$ , or more closely related to our circumstances:

$H=20(1-.8)^n$ and simplifying that a bit:

$H=20(.2)^n$ , choice D.

Coefficient of 24x+32+4x+3

coldgirl [10]

Firstly, you can combine like terms, or terms that have the same variable and exponents.

24x and 4x both have the variable "x" so it can be combined to make 28x

A coefficient is basically just the number that's used to multiply the variable

In this case, the variable is "x" and the number that will be multiplied to x is 28.

<em>The coefficient is 28.</em>

Solving Exponential and Logarithmic Equations In Exercise, solve for x.<br> 500(1.075)120x = 100.000

Volgvan

Answer:

The solution is:

$x = 0.61$

Step-by-step explanation:

The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So

$500(1.075)^{120x} = 100000$

$(1.075)^{120x} = \frac{100000}{500}$

$(1.075)^{120x} = 200$

To find x, we have to apply log to both sides of the equality.

We also have that:

$\log{a^{x}} = x\log{a}$

$\log{(1.075)^{120x}} = \log{200}$

$120x\log{1.075} = 2.30$

$120x*0.03 = 2.30$

$3.77x = 2.30$

$x = \frac{2.30}{3.77}$

$x = 0.61$

Mina tossed two number cubes labeled 1 to 6.What is the probability that the sum is equal to 5

julsineya [31]

You can get a 5 this many ways.
2 + 3
3 + 2
1 + 4
4 + 1

That number is 4
the total number of ways you can throw two cubes is 6 * 6 ways.
Of those ways 4 are successful
4/36 = 1/9 <<<< Answer.
