Answer:
3
Step-by-step explanation:
(x+4) ^ 1/3 = 7
We need to cube each side of the equation
(x+4) ^ 1/3 ^3= 7^3
x+4 = 343
Subtract 4 from each side
x+4-4 = 343-4
x = 339
The power raised on each side is 3
First, turn it into a multiplication problem by multiplying by the reciprocal of the divisor. Then, you can cancel common factors in the numerator and denominator to make things easier to work with. Finally, multiply<span> to get your final answer!</span>
H = –16t2 + 156t + 105, when t = t', the time where the rocket hit the ground after it is launched, so 105= –16t'2 + 156t' + 105, so -16t'2 + 156t' = 0 implies t' =0 or -16t'+ 156= 0, equivalent to t'=9.75, so the answer is
b) <span>9.8 s</span>
To solve for the total price:
1.075(50) = 53.75
She will have to pay $53.75 in total.
