8 is a cube: 2³
27 is a cube: 3³
The expression can be identified as "the sum of two cubes": (2z)³ + 3³.
Answer:
Step-by-step explanation:
<h3>Part A</h3>
<u>Solve the equation:</u>
- 6x² + 48x + 120 = 0
- x² + 8x + 20 = 0
- x² + 8x + 16 + 4 = 0
- (x + 4)² + 4 = 0
- (x + 4)² = - 4
The left side is positive and right side is negative so no solution
<h3>Part B</h3>
There is no intercession with the x-axis, the graph of the function is entirely above the x-axis.
It means the diver won't reach the bottom of the lake
Okayuyyyyyyyyyyyyyyyyyyyyyyyyy
Answer:
the amount that should be worth in 25 years is $2,155,770
Step-by-step explanation:
The computation of the amount that should be worth in 25 years is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= $250,000 × (1 + 0.09)^25
= $250,000 × 1.09^25
= $2,155,770
Hence, the amount that should be worth in 25 years is $2,155,770
