1. The graph is of exponential decay and the equation should be in the form:
f(x) = a (k^-x)
where a is the initial value and k is the multiplicative rate of change. Among the choices, there is no exact correct answer. Most probably, the answer is:
<span>D. ​ f(x)=20(53)x ​

2. The exact answer is:
</span><span>C. f(x)=40(2.25)x
Since the initial value is 40 and the multiplicative rate of change is 2.25

3. The answer is
</span><span>D. f(t)=35,400(1.02)t
Since the initial value is 35400 and the increase is 2%

4. Given this:
</span><span>{(1,80),(2,240),(3,720),(4,2160)}

The function in sequence form is:
p(t) = 80(3)^(t-1)  </span>

Mike is working on solving the exponential equation 37^x = 12; however, he is not quite sure where to start.
Rainbow [258]

The solution of the given exponential equation is 0.688.

Given that Mike is working on solving the exponential equation 37ˣ = 12.

An exponential equation is an exponential equation where the power (or)  part of the exponent is a variable.

firstly, we have to slve this equation is by converting it to logarithmic form. Any exponential equation can be transformed into an equivalent logarithmic equation as follows:

aˣ = y

logₐy = x

Now, we will apply this transformation to our equation and we get

log₃₇12=x

Further, we will apply the change of base formula so that solution is written in terms of base 10 logs:

x=log12/log37

So, this is an exact answer to given equation, but we can simplify it further by using decimal approximation of it using a calculator. Remember that these logs are base 10:

x≈1.079/1.568

x=0.688

Hence, the solution of the given exponential equation 37ˣ=12 is 0.688.

3. Planet Fitness Club charges $30 per month for a membership. 24-Hour Fitness Club charges $22 per month plus an $80 initial fe
umka2103 [35]

Answer:

The number of months after which amount paid to two fitness clubs be the same is 10

Step-by-step explanation:

Given as :

The charge of Mikes fitness center = $30 per month fro membership

The charge of All-Day fitness center= $22 per month fro membership + $80            

                                                              initiation charge

Let The number of months after which amount paid to each club be same = x

So, According to question :

30 x = 22 x + 80

Or, 30 x - 22 x = 80

Or, 8 x = 80

So     x =

∴       x = 10

Hence The number of months after which amount paid to two fitness clubs be the same is 10    Answer

Find the missing side of the triangle. leave your answer in simplest radical form
KIM [24]

missing side is x} = 10.15 mi .

<u>Step-by-step explanation:</u>

Here we have the following info from the figure: A right angled triangle with following dimensions

Perpendicular = x

base = \sqrt{122}

Hypotenuse = 15

By Pythagoras Theorem :

Hypotenuse^2 = Perpendicular^2 + base^2

⇒ Hypotenuse^2 = Perpendicular^2 + base^2

⇒ 15^2 = x^2 + (\sqrt{122})^2

⇒ 225 = x^2 + 122

⇒ x^2 = 225-122

⇒ x^2 = 103

⇒ (x^2)^\frac{1}{2} = (103)^\frac{1}{2}

⇒ x} = (103)^\frac{1}{2}

⇒ x} = 10.15

Therefore, missing side is x} = 10.15 mi .
