To qualify for the championship, a runner must complete the race in less than 40 miles. Use t to represent the time of a runner
1 answer:
Answer:
The inequality which represents the situation is .
Step-by-step explanation:
Given:
Number of miles to complete the race = 40 miles.
We need to write the inequality to represent the situation.
Solution:
Let 't' represent the time of a runner who qualifies for the championship.
SO now we can say that;
time of a runner who qualifies for the championship should be less than Number of miles to complete the race.
framing in equation form we get;
Hence The inequality which represents the situation is .

This will be an exponential function. To find the growth rate, we can write out the terms of the sequence that goes along with it: 10, 20, 40, ...
"Growth rate" is the same as percent of increase or decrease. We find the amount of increase and divide by the original amount: 20-10 = 10 increase; 10/10 = 1.
The exponential function is of the form
f(x) = a*(1+r)ˣ, where a is the initial value (10), r is the growth rate (1), and x is the number of time periods. Using the variables given to us in the problem along with this information, we have:
Divide both sides by 10:
We will use logarithms to solve this:

14×16
Step-by-step explanation:
The plan of the mausoleum measures 35 metres (width) by 40 metres. It is 2.5 m per square. When redecorating the grave on the grid, 14 (width) by 16 (height) squares should be counted.
