Let f(x) = 3x +5 and g(x) = -4x +7. Find (fog)(-4)

Answers

Answer 1

Answer: (fog)(x)=f(g(x))

f(g(x))=3(-4x+7)+5
f(g(-4))=3(-4(4)+7)+5=3(-16+7)+5=3(-9)+5=-27+5=-22

(fog)(-4)=-22

If y= x^3 + 1, find y when x= 2

Answers

y = x³ + 1

subtitute x = 2 to the equation

y = 2³ + 1 = 8 + 1 = 9

$y = x^3 + 1$

$y = 2^3 + 1$

$8 + 1 = 9$

you invest 4,400 in an account that pays an interest rate of 6.5 % compounded continuously ,calculate the balance of your account after 3 years .round your answer to the nearest hundreth

Answers

This is a problem that deals with exponential growth and the formula for exponential rate problems is: $y = a(b)^t$ , where a= principal amount, b = rate, and t = time.

Let's substitute the corresponding values into its appropriate places: the starting amount is $4,400, the rate is 0.065 but we need to add an 1 because it's an exponential growth problem so it would be 1.065, and the time is 3 years.

Now solve:
[tex]y = $4,400(1.065)^3[tex]
