Compound interest formula:
A = P(1 + r/n)^nt
A = Final amount
P = starting amount
r = interest rate
n = number of compounding per year
t = number of years
A = 80(1+ 0.035/1)^(1*44)
A = 80(1.035)^144
A = $11,337.06
Answer:
= cos4x
Explanation:
cosAcosB = [cos(A-B)+cos(A+B)]
Given: 2cos(2x)cos(2x)
= 2[cos(2x-2x)+cos(2x+2x)]
= 2cos4x^2
Step-by-step explanation:
Find 1 pack of pencil:
1 pack = 10 ÷ 5 = $2
9 packs = 2 x 9 = 18
Answer: $18
Answer:
Step-by-step explanation:
C. -11<x<-4
|-2x-15|<7 split into possible cases
- 2x - 15 < 7, - 2 x - 15 > 0
-(- 2x - 15 ) <7, -2x - 15 < 0 solve the inequalities
x>-11, x < -15/2
x< -4, x> -15/2 Find the intersections
[ -11, -15/2 ]
-15/2, -4] Find the union
[-11, -4 ] Simplify
-11<x<-4
Answer:
(x+8)(x+1)
Step-by-step explanation:
i am sorry but i didn't understand after the equation.
but i think i got what you trying to ask so this is
i got (x+8)(x+1)
