Answer:

20 degrees

Step-by-step explanation:

F=9/5C+32 (c=Celsius) There are a few ways to do this but im going to do it my way.

68=9/5C+32 (plug in)

36=9/5C (subtract 32 from both sides)

180=9C (multiply by 5)

20=C (divide by 9)

Write an exponential function y = abx for a graph that includes (–3, 16) and (–1, 4) f(x) = 2(0.5)x f(x) = 0.5(2)x f(x) = 4(0.3)
Arisa [49]

Answer: f(x)=2(0.5)^x

Step-by-step explanation:

Given, the exponential function y = ab^x for a graph that includes (–3, 16) and (–1, 4).

On putting these points, we will have

f(-3)=16=ab^{-3}\\\\ f(-1)=4=ab^{-1}

Now,

\dfrac{f(-3)}{f(-1)}=\dfrac{16}{4}=\dfrac{ab^{-3}}{ab^{-1}}\\\\\Rightarrow\ \dfrac{4}{1}=\dfrac{b^{-3}}{b^{-1}}\\\\\Rightarrow\ \dfrac{4}{1}=\dfrac{b}{b^3}=\dfrac{1}{b^2}\\\\\Rightarrow\ b^2=\dfrac{1}{4}\\\\\Rightarrow\ b=\pm\dfrac{1}{2}=\pm0.5

since the multiplicative factor cannot be negative, so b= 0.5.

At b= 0.5

4=a(0.5)^{-1}\\\\\Rightarrow\ 4=a(\dfrac{1}{2})^{-1}\\\\\Rightarrow\ 4=a(2)\\\\\Rightarrow \ a=2

So, the required function is f(x)=2(0.5)^x.
