Answer:
616cm³
Step-by-step explanation:
you just need to multiply those numbers
7 x 8 x 11= 616
The answer is 20.25 since 2/9 is .2 repeating and that to the power of -2 is 20.25
To answer this item, all that needs to be done is dividing the mathematical expression of x⁵ - 10⁵, our dividend, by x - 10, which is our divisor.
The mathematical expression that can be used in order to properly express the given scenario is,
x⁵ - 10⁵ = (x - 10)(a)
The value of a, as stated above, can be calculated by the equation,
a = (x⁵ -10⁵) / (x - 10)
There are two ways to solve the problem: synthetic division and the long way. Each of which will yield the same answer. Simplifying the value of a will give us a final answer of,
<em> a = x⁴ + 10x³ + 100x² + 1000x</em>
No, They will need 131.94 more dollars.
The exponential growth formula can help us find how much is to be deposited each month and then adding them together for the 5 months after the initial deposit will give us the amount saved.

a is the initial value (120)
r is the rate of growth (0.25)
x is time [0,1,2,3,4,5)
