Answer:
B) 14%
Step-by-step explanation:
principal = 220000
First two years 10% paid.
.10 x 220000 = 22000
220000-22000 = 198000
x = percent
x =
x =
x = -.1414
Round to .14
14% is the difference in amounts.
The principal (198000) will need to be reduced 14% to equal 170000
Answer:
a
Step-by-step explanation:
9(5x)=45x
9(2)=18
4(8)=32
4(-x)=-4x
45x-4x=41x
32+18=50
41x+50
Answer:
T(0, -3)
Step-by-step explanation:
Answer:
So the radius is increasing at .
This is approximately 0.00497 cm/min that the radius is increasing.
Step-by-step explanation:
The volume and radius are both things that are changing with respect to time.
So their derivatives will definitely not be 0.
Let's differentiate:
I had to use constant multiple rule and chain rule.
We are given and .
We want to find .
Let's plug in first:
Multiply both sides by 3:
Divide both sides by :
So the radius is increasing at .
This is approximately 0.00497 cm/min that the radius is increasing.
-6 < x + 1 ≤ 1
<u>-1 -1 -1</u>
-7 < x ≤ 0
-7 < x or x ≤ 0
x > -7 or x ≤ 0
