F ( 6 ) = -16·6²+32·6+90= -576 + 192 + 90 = -294
f ( 4 ) = -16· 4³+32·4+90=-256+128+90= -38
The average rate of change: [f(t2)-f(t1)]/ t2-t1=
[-294-(-38)] / (6-4) = -256 : 2 = -128 feet/s
500/7 = 71.43 gallons per hour
950-500 = 450
450/71.43 = 6.3 more hours.
Answer: n=-5/3
Step-by-step explanation:
18n=-27-3
18n=-30
N=-30/18
N=-5/3
Hope this helps! :)
7 is the answer because de is parallel to xy.
The slope of the line passing through the points (-4 , 0) and (7 , 0) is 0 ⇒ 3rd answer
Step-by-step explanation:
The formula of the slope of a line is
where and are two points on the line
To find the slope
- Let one of the two points to be
- Let the other point
- Substitute them in the formula of the slope
- Calculate the value of m
∵ The line passes through points (-4 , 0) and (7 , 0)
∴ = -4 and = 7
∴ = 0 and = 0
- Substitute these values in the formula above
∴
∴ m = 0
The slope of the line passing through the points (-4 , 0) and (7 , 0) is 0
