we know that
If line b is perpendicular to line a, and line c is perpendicular to line a,
then
line b and line c are parallel
and two lines parallel have the same slope
so
<u>Find the slope of the line b</u>
Let
The formula to calculate the slope between two points is equal to
substitute
therefore
<u>the answer is</u>
<u>the slope of the line c is</u>
Answer:
42 feet.
Step-by-step explanation:
h=-10t² + 40t +2
The vertex of the quadratic function described by the equation is located at
t = -(40)/(2(-10)) = 2
Next is to find the value of height at t=2 will be
h = -10(2²) +40(2) +2 = -40 +80 +2 = 42feet
The maximum height is 42 feet.
1. 100 * 20
2. 7 hours
3. 141 kilometers
4. 8.5 hours
5. 55.75 mi/h
5% = .05
2600 x .05 = 130
130 x 2 = 260
2600 - 260 = 2340
The population will be 2340 people.
Answer:
93
Step-by-step explanation:
Given that:
Brittany's Zscore = 1.8
Mean score (m) = 75
Standard deviation (s) = 10
Brittany's score (x) =?
Using the Zscore formula :
Zscore = (x - m) / s
1.8 = (x - 75) / 10
18 = x - 75
18 + 75 = x
93 = x
Hence, Brittany's score is 93
