Answer:
f(x) = 3x⁴ -
- 17x + 
Step-by-step explanation:
To find f'(x), we will follow the steps below:
We will start by integrating both-side of the equation
∫f'(x) = ∫(12x^3 - 2x^2 - 17)dx
f(x) = 3x⁴ -
- 17x + C
Then we go ahead and find C
f(1) = 8
so we will replace x by 1 in the above equation and solve for c
f(1) = 3(1)⁴ -
- 17(1) + C
8 = 3 -
- 17 + C
C =8 - 3 + 17 + 
C = 22 + 
C =
C = 
f(x) = 3x⁴ -
- 17x + 
Answer:
1. x=60
2.x=5
3.x=8
4.x=10
Step-by-step explanation:
im assuming you want to find x value for each.
Answer:
(x+6)^2 =0
Step-by-step explanation:
x^2+ 12x + 36 = 0
Subtract 36 from each side
x^2+ 12x + 36-36 = 0-36
x^2 +12x = -36
Take the coefficient of x
12
Divide by 2
12/2 =6
Square it
6^2 =36
Add this to each side
x^2+ 12x + 36 = -36+36
(x+12/2)^2 = 0
(x+6)^2 =0
The answer is b. k=64 t=52
Answer:
C. 60%
Step-by-step explanation:
<u>Consider 1st row of table</u>
Total Price = P= 22.50
Discount=D=13.50
Percent discount=(D/P) x 100
=(13.5/22.5) x 100
= 60%
<u>Consider 2nd row of table</u>
Total Price = P= 27
Discount=D=16.20
Percent discount=(D/P) x 100
=(16.2/27) x 100
= 60%
Now we know discount rate is r=60%
