Answer:
Approximately $594.38
Step-by-step explanation:
Use the formula: y = a(1 + r)^t
a is the initial amount
r is the percent of interest in decimal form
t is the time in years
y is the money after t years
Substitute the values given in the problem into the equation:
400(1+0.02)^20
Use a calculator or solve manually
Around 594.38
Answer:
-2
Step-by-step explanation:
3-2n=7
-3 -3
-2n=4
divide both sides by -2
n=-2
Answer:
14
Step-by-step explanation:
1) To find the distance between two points you'll need to use the distance formula:
d=
2) Figure out which points you'll want to set:
(x1,y1) = (-4,2) (x2,y2) = (10,2)
3) Substitute your values into the formula:
Answer:
6x^2 - 2
Step-by-step explanation:
plug in f(x) into the g(x) formula given
g(f(x)) = (3x)^2 + 1
simplify
= 9x^2+2
plug in g(x) into the f(x) formula given
f(g(x)) = 3(x^2+1)
distribute
= 3x^2 +3
set g(f(x)) - f(g(x))
(9x^2+2) - (3x^2+3)
carry the negative
9x^2+2-3x^2-3
simplify by combining like terms
6x^2-2
