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:
Option B. It represents a nonlinear function because its points are not on a straight line.
Step-by-step explanation:
Let
we know that
If point A,B and C are on a straight line
then
The slope of AB must be equal to the slope of AC
The formula to calculate the slope between two points is equal to
<em>Find the slope AB</em>
substitute in the formula
<em>Find the slope AC</em>
substitute in the formula
so
Points A, B and C are not on a straight line
therefore
It represents a nonlinear function because its points are not on a straight line
Slope is 2/1 , because the formula to find the slope is rise/ run
= 6/3
= 2/1
There's no solution in the set of real numbers.
twin sides stemming from a common vertex, make twin angles, since the HG = HF, then ∡G = ∡F.
