Answer:
g(f(x)) = 8x-18
Step-by-step explanation:
Given that,
f(x) = 5 - 2x
g(x) = -4x + 2
We need to find g(f(x))
.
g(f(x)) = g(5-2x)
= -4(5-2x)+2
= (-4) (5) +(-4)(-2x) +2
= -20 +8x +2
= 8x-18
Hence, the value of g(f(x)) is 8x-18
Answer:
Option A
Step-by-step explanation:
Since at. 0.05 level of significance, the p value was great than 0.05 but less than 0.1, we will fail to reject the null and conclude that the sample data does not provide enough evidence that the average life of the batteries is greater than 75 weeks.
Answer:(-1,2)
Step-by-step explanation:
Answer:
238.65
Step-by-step explanation:
To find the simple interest we use the formula:
A = P(1 + rt)
Let's break down all the variables that we have.
P = 3,700
r = 2.15% or 0.0215
t = 3
So let's put all our variables into the formula.
A = P(1 + rt)
A = 3,700(1 + (0.0215)(3))
A = 3,700(1 + 0.0645)
A = 3,700(1.0645)
A = 3938.65
Gary will have a total of 3938.65 in his account after 3 years. Now to find how much he made in interest, we simply subtract the total after 3 years to his initial amount.
Interest = 3938.65 - 3700
Interest = 238.65
