Answer: The exponential function would be
Step-by-step explanation:
Since we have given that
We have points (0,15) and (2,24)
First we take when x= 0, y = 15.
So, our equation becomes,
and we take when x = 2 and y = 240
So, the exponential function would be
x y
-1 1
-2 2
-3 3
---------------
x y
1 -1
2 -2
3 -3
Answer: 140 female runners
Step-by-step explanation:
First find out the number of runners:
= 42% * 10,000
= 4,200 runners
Then find out the number of female runners:
= 4,200 * 1/3
= 1,400 female runners
Sally finished faster than 90% of the female runners which means that 10% finished faster or at the same time as her.
= 10% * 1,400
= 140 female runners
Answer:
a = 0 or a = -7
Step-by-step explanation:
We are going to solve this quadratic equation by factorizing.
a² - 7a = 0
a(a - 7) = 0
a = 0 or a - 7 = 0
a = 0 or a = -7
Using proportions, it is found that the correct amount to administer of CC would be of:
A. 0.5.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 500 mg are equivalent to one cc. How many cc are equivalent to 250 mg? Hence the <em>rule of three</em> is given by:
500 mg - 1 cc
250 mg - x cc
Applying cross multiplication:
500x = 250
c = 0.5.
Hence option A is correct.
