Answer:
Step-by-step explanation:
We are given;
- A point where the line is passing through as (3, -4)
- The slope of the line -1/2
We are required to determine the equation of the line;
- Note that, one way we can get the equation of a straight line is when we are given a point where the line is passing through and its slope.
- Thus, in this case, we can determine the equation;
Taking another point (x, y)
Then; (x, y) , ( 3, -4) and slope -1/2 can give us the equation;
That is;
Cross multiplication;
Combining the like terms;
Thus, the equation of the line is;
Answer:
1) 37.7 ft 2)75.4
Step-by-step explanation:
the formula for circumference= 2 x radius x pi
so i halved the first one as its the diameter but for the second one they already gave the radius
hope this helps!
Answer:
3
Step-by-step explanation:
The solutions are
- it is going to take 15.9 months to raise 10000 dollars
- You will have $37.31 after you have bought the car
- The money deficit would be $37.31
<h3>How to solve the question</h3>
a. 10000 = 9359.08e(0.05)
e⁰⁰⁵ = 10000/9359.08
= 0.05 = ln(10000/9359.08)
= 1.325 years
convert to months = 15.9 months
Hence it is going to take 15.9 months to raise 10000 dollars
b. 9359.08 x e^(0.05 x1.25)
= 9962.69
10000 - 9962.69
= $37.31
You will have $37.31 after you have bought the car
c. The money loss and the deficit would be same as above $37.31
d. ln(e^a) = a
We can clearly see that the money cannot be raised in the 15 months from $ 9359.08. there is a deficit amount of $37.31

Answer:
25%
Step-by-step explanation:
Her profit is $20,000 on her cost of $80,000, so is ...
20,000/80,000 × 100% = 25%
