The slope of the line that passes through (5, 4) and (-4,3) is 
<u>Solution:</u>
Given, two points are (5, 4) and (-4, 3)
We have to find the slope of a line that passes through the above given two points.
Slope of a line that pass through
is given as:



Hence, the slope the line that passes through the given points is 
3.
a.∠BED = 90°
b.CD is perpendicular to AB. CD intersects AB at the midpoint
c. AE = 1/2AB
d. If AB=18, then AE is 9
e. CD is the midpoint of AB
4.If AB = 58, then


Answer:
13.55 hours
Step-by-step explanation:
given that the lifetime of a certain type of battery is normally distributed with mean value 13 hours and standard deviation 1 hour.
Sample size=n =9
Sample mean = 
Let c be the lifetime value is such that the total lifetime of all batteries in a package exceeds that value for only 5% of all packages
Then we have 
Convert into Z score to get

z =1.645 from std normal distribution table
Hence x = 
Answer is 13.55 hours
The number of years it will take for the money to be $2900 is 40.91 years
<h3>How to find the years the money will accrue to 2900 dollars?</h3>
Using simple interest formula,
I = prt / 100
we are looking for t
where
- p = principal
- r = rate
- t = time
- I = simple interest
Therefore,
I = 2900 - 1100 = 1800
1800 = 1100 × 4 × t / 100
cross multiply
180000 = 4400t
t = 180000 / 4400
t = 40.9090909091
t = 40.91 years
