Which exponential function goes through the points (1, 32) and (4, 2048)?

worty [1.4K]

Answer: f(x) = 4*(4)ˣ Option C

Explanation:

We know the standard function of exponential function :

f(x) = a*bˣ

where is initial value

b is growth factor

x is time

Now given that two coordinates (1,32) & (4,2048)

Now put x = 1, f(x) = 32

32 = a*b¹

a*b = 32 ----------------------- (1)

now use second point

2048 = a * b⁴

a*b⁴ = 2048 ----------------------(2)

Now divide (2) / (1)

b³ = 64

b = 4

Put b = 4 in equation (1)

a (4) = 32

a = 8

So, final function is :

f(x) = 8*(4)ˣ

An English instructor asserted that students' test grades are directly proportional to the amount of time spent studying. Lisa

hodyreva [135]

Answer:

Lisa has to study for 7.55 hours.

Step-by-step explanation:

Since an English instructor has asserted that the relation between studies and test grades is proportional then we can find the time by unitary method.

∵ To score 77 Lisa has to study for 6 hours.

∴ To score 1 Lisa has to study for = $\frac{6}{77}$

∴ For a score of 97 Lisa has to study = $\frac{6}{77}(97)$

= 7.55 hours

So Lisa has to study 7.55 hours to score 97 in the test.
