Answer:
1. 
2. 
Step-by-step explanation:
1. Solution for 1st part.
Given:
Ben shared his post with 2 friends
Each of those friends shares with 3 more every day.
the number of shares triples every day.
From the data given above, we can make the following:
An exponential function is represented by:
where a is the initial value and b is the growth rate.
The exponential function for this case would be:
2. Solution for part 2.
Given:
Carter shared his post with 10 friends.
each share with only 2 people each day.
From the data given above, we can make the following:
An exponential function is represented by:
where a is the initial value and b is the growth rate.
The exponential function for this case would be:

<h2>The answer is
.</h2>
Step-by-step explanation:
Let the building contractor bought 1000 cement in total.
70% of 1000 = 700 cements were from A and (1000 - 700) = 300 cements were from B.
The number of undamaged bag from A was 95% of 700 = 
and the number of undamaged bags from B was 70% of 300 = 
.
Total undamaged bags were (665 + 210) = 870.
The probability that an undamaged bag is from A is 
.
Answer:
3x^2-4x+20/x^2-5x .
Step-by-step explanation:
The given rational expression is:
3x/x-5 - 4/x
Hence to find the difference of the rational numbers we have to take the L.C.M of the denominators:
Thus the L.C.M of x-5 and x is (x-5)(x) and then solve for the numerator:
x(3x) - 4(x-5)/(x-5)(x)
Now solve the numerator and denominator:
3x^2-4x+20/x^2-5x
Thus the answer is 3x^2-4x+20/x^2-5x ....
Answer:
6 is the ans
Step-by-step explanation:
Write a Pythagorean triplet whose one member is.
2m, m 2 − 1 , m 2 + 1 \mathrm{m}^{2}-1,
mathrm{m}^{2}+1 m2−1,m2+1 is a Pythagorean triplet.
∴ (6, 8, 10) is a Pythagorean triplet.
