I will assume that A = 72 yd^2 is the area of the rhoumbus.

The formula of the area is diagona 1 * diagonal 2 / 2

Then d1*d2 / 2 = 72

d2 = 72*2/d1 = 72*2/16 = 9 yd

Area of the rhombus:
A =  d 1 · d 2 / 2
72 = 16 · d 2  / 2
72 = 8 · d 2
d 2 = 72 : 8
Answer: d 2 = 9 yd

Let f(x) = cx^k be a power function such that f(13) is four times the size of f(1). What is the power k?
Ivenika [448]

Answer:

0.540

Step-by-step explanation:

Hi there,

To get started in order to solve this, please recall the property of logarithms.

This question is a bit tricky, but doable. Best way to solve this is first compare the two functions:

f(x) = cx^{k} \\ f(13)=4f(1)  

Now, let's see what the function gives at 13 and 1:

f(13)=c13^{k}\\f(1)=c1^{k}

Something to recognize is that 1 to the power of <em>anything</em> is just 1, so f(1) is reduced to:

f(1)=c  We are making progress!

Next, we can set both f(13) forms equivalent to each other, watch this:

f(13)=f(13) = 4f(1) but we know what f(1) is equal to, and let's substitute our knowns:

c13^{k}=4c1^{k} = 4c the c constant on both left and right side cancel out:

13^{k}=4 Now, take the logarithm form of both side of the equation. I used natural log, but you can also use common logs:

ln(13^{k})=ln(4)  ⇒ k*ln(13)=ln(4) this was performed using <em>the power  log rule. </em>

Isolate k:

k=\frac{ln(4)}{ln(13)} =0.540 using a calculator.
