Answer:
The amount after 4 years = $ 16198.87
Step-by-step explanation:
Points to remember
Compound interest
A = P[1 + R/n]^nt
Were A - Amount
P - Principle
R - Rate of interest
t - Number of years
n - Number of times compounded
<u>To find the amount</u>
Here P = $11,800, R = 8% = 0.08, t = 4 years and n = 4 times
A = P[1 + R/n]^nt
= 11800[1 + 0.08/4]^(4 * 4)
= 16198.87
Therefore amount after 4 years = $ 16198.87
Answer:
Step-by-step explanation:
The slope is the difference in y-coordinates of the 2 points divided by the corresponding difference in x-coordinates.
For example:
Find the slope of the line joining the points (3, 5) and (-2, 1)
The slope = (5 - 1) / (3 - (-2))
= 4/(3+2)
= 4/5.
NOTE:
You would get the same result if you reversed the values
- that is (1 - 5)/(-2 - 3
= -4/-5
= 4/5.
The important thing to remember is to use <em>corresponding </em>values in the calculation.
Answer:
(7, - 7 )
Step-by-step explanation:
- 4x + y = - 35 → (1)
- 2x - y = - 7 → (2)
adding the 2 equations term by term will eliminate the y- term
(- 4x - 2x) + (y - y) = - 35 - 7
- 6x + 0 = - 42
- 6x = - 42 ( divide both sides by - 6 )
x = 7
substitute x = 7 into either of the 2 equations and solve for y
substituting into (1)
- 4(7) + y = - 35
- 28 + y = - 35 ( add 28 to both sides )
y = - 7
solution is (7, - 7 )
131.88 or jus do radius times 2 so 21+ 21 = 42.
42 x pi(3.14) = 131.88
Answer:
Step-by-step explanation:
use the formula y=mx+b. the first number in the parenthesis is -3 so that is x. 3 is y and the slope is m
so it is 3=4(-3)+b
