Answer:
the answer would be 211
Step-by-step explanation:
you simply add the length and width together to find perimeter. since you have the total perimeter and the length you would instead subtract the two.
292-81= 211
Answer: Function
f(x) = -2(x-105)^2 +18,050
Step-by-step explanation:
Because only this function satisfies both conditions i.e.
Condition : 1
Profit = 0, when x(items sold) = 10
f(10) = -2(-95)^2 + 18,050 = 0
Condition :2
Profit = 1 , when x = 105
f(105)= -2(105-105)^2 + 18,050 = -2(0) +18,050
f(105) = 18,050.
An equation in point-slope form that passes through point P(a,b) is as follows:
y-b=m(x-a) where m=slope, a,b are coordinates of point P.
For a line to pass through P(4,-8)
the equation will look like:
y-(-8) = m(x-4)
simplify left side
y+8=m(x-4)
The given equation has a slope of m=-1/2, so the slope of a line perpendicular to it has a slope of -1/m = -1/(-1/2)=+2
Now go through the answer choices:
a. y+8=2(x-4) => passes through P(4,-8) and has a slope of 2. so TRUE
b. y-4=2(x+8) => has a slope of 2, but passes through (-8,4), which is not P so FALSE
c. y+8=(1/2)(x-4) => passes through P(4,-8), but has the wrong slope (a reflection, not perpendicular) so FALSE
d. y-8=(1/2)(x+4) => passes through a wrong point (-4,8) and has the reflected slope (not perpendicular) so FALSE
80/5=16
16*3=48
80-48=32
32\5=6.4
