Answer:
ok from looking at this we can see that it goes up one hour for every 25 miles so
25mph
Hope This Helps!!!
Answer:
the photo is black..i cant see the question...
Step-by-step explanation:
3(5^x) is an exponential function.and which rise very fast
y = 127 - 2x is a line Which decrease wçith a 2 slope f(0) = 127
3.5^2 = 75 and 3.5^3 = 375
I guess the intersection will be between 2and 3
lets put both the functions in a graph calculator
window:
x between 2 and 3
y between 75 and 127
I have an intersection between 2 and 3
use the "table" of the calculator
we can see that the intersection is between 2.3 and 2.4
try again
range:
start:2.3
end 2.4
intersection is in [2.3;2.31]
lets say it's 2.305
15% = 0.15
Multiply:
0.15 × 60 = 9
Answer = 9
Hope this helped☺☺
Answer:
Day 21: 810 m
Day 60: 1,200 m
Step-by-step explanation:
The amount of meters she walk everyday can be modeled as a linear function, as the rate of variation is a constant (10 m/day):

This constant (10 m/day) is the slope of the linear function.
We know one point of the linear function (D(20)=800) and the slope, so we can calculate the y-intercept:

Now, we can calculate the distance she walks by day 21 and day 60:
