Answer:
D
Step-by-step explanation:
Firstly,you must divide (6,2) to (x¹y¹).After that,you must divide (10,3) to (x²y²).Then you must substract (y²-y¹,x²-x¹).It will be like this (3-2,10-6).So the correct answer is 1,4 (D).Hope you will understand!
10. The compass length (3 inches) represents the radius of the circle that is about to be drawn.
We know an equation for the area of a circle is pi x r^2
So lets use that equation
A (circle) = pi x 3^2 = pi x 9 = 28.3 square inches
and 11 is one fourth
Answer:
The found the slope incorrectly
The found x over y instead of y over x
Step-by-step explanation:
We first need to find the slope
m = (y2-y1)/(x2-x1)
= (6-3)/(4 --2)
= 3/6
=1/2
The found the slope incorrectly
The found x over y instead of y over x
Answer:
75 km/hr
Step-by-step explanation:
So, if a car travels 150 km in 2hours.
Then;
f(t=0) = 0
f(t = 2 hours) = 150 km
Therefore;
f'(c) (speedometer reading) = f(t=2)-f(t=0)/(2-0)
f'(c) (speedometer reading) = 150/2 km/hr
f'(c) (speedometer reading) = 75 km/hr
C
work:
75 is equal to 2x+15
75-15 = 60
60/2 = 30
x=30
