I will only do the first-three. You can repost number 4.

Question 1

f(x) = -x^2 + 10x + 4

dy/dx = -2x + 10

Question 2

f(x) = 20 - x + 2

dy/dx = -1

Question 3

f(x) = ex^4 - 2x^2

dy/dx = e•4x^3 + x^4 - 4x

dy/dx = 4ex^3 + x^4 - 4x

Clint needs to decrease his budget for groceries by 5% each month. He currently allots for $500 a month on groceries. What will
Radda [10]

Answer:

$386.9

Step-by-step explanation:

Given that current grocery costs are $500 and he want to reduce 5% every month

We can create a geometric progression with a = 500 and common ratio(r) = 0.95

because every time we reduce 5% we actually make the actual cost as 95%

T(n)=ar^{n-1}

Now we should find n=6

T(6)=500\times(0.95)^{6-1}

t(6)=386.9

The allotment is $386.9
