Answer:
Option C.The decrease in the value of the motorcycle, which is 9%
Step-by-step explanation:
we have a exponential function of the form
where
a is the initial value
b represents growth or decay factor
If b >1 then it is an exponential growth
if 0<b<1 then it is an exponential decay
In this problem
a=$19,000
b=0.91 -----> it is exponential decay factor
Find the rate of decrease r
b=(1-r)
substitute
0.91=1-r
r=1-0.91=0.09
Convert to percentage
0.09*100=9%
therefore
0.91 represent the decrease in the value of the motorcycle, which is 9%
-17/15
Find a common denominator, and multiply the numerator by the same factor. Don't forget that adding a negative is really subtracting.
I think it is 81 but I'm not sure
Area of rectangle = 24/54 square miles
length(L) = 5/9 miles
width (W)= ?
area = L * W
25/54 = 5/9 * W
W = (25/54) / (5/9) = (25 * 9) / (54 * 5)
W = 5/6 miles
Hey there Hopire :)
To solve this, we'll use the slope given two points formula. Here it is:
y2-y1/x2-x1
Plug in the values.
6-2/9-7 =
4/2 =
2
Therefore, the slope is two, meaning 2/1 because slope is rise/run. That means that for every two you go up, you go one to the right because it's a positive slope- left for negatives.
Hope this helped!
