Answers
Answer:
18.2 m = height of the building
Step-by-step explanation:

Do not factor by grouping. Solve 2(x-2)^1/3=x+2
Answers
Step-by-step explanation:
2(x-2)⅓=x+2
so we first cube each side,such that...
(2(x-2))⅓•³=(x+2)³
we get...
2(x-2)=(x+2)³
expanding...
2x-4=x³+6x²+12x+8
grouping....
x³+6x²+12x+8-2x+4=0
solving...
x³+6x²+10x+12=0
now you can use you calculator to solve for the possible values of x

You want to buy a new car. You can afford payments of $300 per month and can borrow the money at an interest rate of 5.2% compounded monthly for 5 years.
Answers
Answer:
$367.17
Step-by-step explanation:
we are find the cost of the car after 5 years
Using the compound interest formula;
A = P(1+r/n)^nt
Given
Principal P = $300
rate r = 5.2% = 0.052
Time t = 5years
Time of compounding n = 1/12 (monthly)
Substitute into the formula
A = 300(1+0.052(12))^5(1/12)
A = 300(1+0.624)^0.4167
A = 300(1.624)^0.4167
A = 300(1.2239)
A = 367.17
hence the amount of the car after 5years is $367.17

UF = 10 . . . AD = 6
FN = 4 . . . DY
NU = 8 . . . YA
Corresponding sides are proportional, so we have ...
DY/4 = AD/UF = 6/10
DY = 4(0.6) = 2.4
