Answer:
48
Step-by-step explanation:
-2(1)^2(3(1)^2 – 7(1) + 10)
-2^2(3^2 – 7 + 10)
4(9 - 7 + 10)
4(12)

Answer:
13 miles
Step-by-step explanation:
27.50- 1.50(fee)=26.00 26/2(2$per mile)=13 miles
A) Height -7 = base
B) .5 * height * base = 60
Substituting A into B
B) .5 * height * (height -7) = 60
B) .5*height^2 -3.5*height = 60
B) .5*height^2 -3.5*height -60 = 0
Using the quadratic formula:
Height = 15
Subtracting 7 gives us the base length
Base = 8
**************************************************************
Double-Check
.5 * 15 * 8 = 60
Answer:
<u>y = 320,000 ( 1.048 ) ^x</u>
x = number of years
(the ^ before the x symbolizes "to the power of," but I can't do that on my keyboard)
Step-by-step explanation:
formula i used:
A = <em>amount that you start with</em>
t = amount of years / time
%increase: you must convert your percent (4.8%) to a decimal (0.048)
A ( 1 + %increase ) ^t
