Answer:
"To the nearest year, it would be about 9 years"
Step-by-step explanation:
11c)
This is compound growth problem. It goes by the formula:
Where
F is the future amount
P is the present (initial) amount
r is the rate of growth, in decimal
t is the time in years
Given,
P = 20,000
r = 8% = 8/100 = 0.08
F = double of initial amount = 2 * 20,000 = 40,000
We need to find t:
To solve exponentials, we can take Natural Log (Ln) of both sides:
Using the rule shown below we can simplify and solve:
We can write:
To the nearest year, that would be about 9 years
Answer:
1. One solution
2. Infinite solution
3. No solution
Step-by-step explanation:
1. y = -4x - 5.........eq 1
+ (y = -4x + 1)..........eq 2
---------------------
2y = -4
divide by 2
2y/2 = -4/2
y = -2
solve for x
put y in any equation
from equation 1
y = -4x - 5
-2 = -4x -5
combine the like terms
-2+5 = -4x
3 = -4x
divide by -4
3/-4 = -4x/-4
x = -0.75
One solution
2. -3x + y = 7
2x - 4y = -8
Infinite solution
3. 3x - y = 4
6x - 2y =8
No solution
We want to write an expression for "the product of the square of h and eight".
The square of h = h².
The product of "the square of h" and eight = (h²)*8 = 8h².
Answer: 8h²
