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.

Which function is not a translation of f(x)=x2+17? f(x)=−x2−17 f(x)=(x−4)2 f(x)=(x+12)2 f(x)=(x−4)2+17
ruslelena [56]
F(x) = -x²-17 is not a translation.

A translation of this graph would either have something added to/subtracted from the end of the function (the c value) or something added or subtracted to x before it is squared.  f(x) = -x²-17 is a reflection, as the coefficient of x² is negative.

Every other choice has something either added to or subtracted from either x before it is squared or from the end.

If a tightrope walker falls, he will land on a safety net. His height h in feet after a fall can be modeled by h(t) = 60 - 16t2,
hjlf
As we know that
<span>h = 60 - 16t^2 </span>
<span>t = sqrt((60 - h)/16) </span>
<span>= sqrt((60 - 11)/16) </span>
<span>= 1.75
hope it helps</span>

Hi guys.I just need to know to fix my story.My story was “Before ally started to run her speed was 0mph but then as she ran fast
oksano4ka [1.4K]

Answer:

instead of just pointing out the highest speed or one speed, list all the different speeds or increasing/decreasing and the different intervals

ie for minutes 2 to 3, her speed was 30 mph . . . from minutes 6 to 8, her speed was decreasing at a constant rate of -2 mph/min
