the slope of the given point is m=−3/4
Answer:
Step-by-step explanation:
Set up a proportion.
3/25 = x / 20 Notice that both times are in the denominators. Be sure you always set up a proportion that way. Like units in the denominator. Like units in the numerator.
Cross multiply
3 * 20 = 25 * x Combine
60 = 25x Divide by 25
60/25 = x
x = 2.4 miles in 20 minutes.
We are supposed to explain why the given function can be expressed in form , when .
Since the given function is an exponential function we can express it as .
Now let us substitute x=0 in the given function,
Let us substitute x=0 in our function.
Upon substituting a=1 in our function we will get,
Therefore, our function f can be represented by the formula of the form .
Answer:
250
Step-by-step explanation:
40% = 100
100 x 2 = 200 and 80%
40/2 = 20%
100/2 = 50
20% + 80% = 100%
50 + 200 = 250
