Answer:
6%
Step-by-step explanation:
Simple Interest formula:
S.I=P×R×T/100
where
S.I is simple interest
P is principle amount
R is Annual interest rate
T is time period
[usually represented as (number of months)/12]
so
$18=$400×R/100×9/12
simplify
$18=$3600R/1200
$18=$3R
so R=$18/$3
=6
Therefore,
The Annual Interest Rate is 6%

Step-by-step explanation:
Pick two points on the line and determine their coordinates.
Determine the difference in y-coordinates of these two points (rise).
Determine the difference in x-coordinates for these two points (run).
Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
64*3= 192 I multiplied that because the car traveled for 3 hours at the speed of 64 miles.
64-15= 49 I subtracted 15 out of 64 because the car only traveled 45 minutes after the three hours.

Answer:
d
Step-by-step explanation:
cosA^2 = 1 - sinA^2
subtitute 1/4 below
= 1 - (1/4)^2
= 1 - 1/16
after calculation
= - 0.9682
Answer:
-7x^3+8x^2+x-5
Step-by-step explanation:
We are simply adding the two functions:
f(x) + g(x) = (2x^2-5x^3+x-7) + (6x^2-2x^3+2) = 8x^2-7x^3+x-5 = -7x^3+8x^2+x-5
