Answer:
the slope is 2
the y intercept is (-4,0)
Step-by-step explanation:
slope is calcuated by rise over run
Answer:
r^8
Step-by-step explanation:
r 2 • r • r 5
Assuming that r 2 means r^2
r ^2 • r • r^ 5
When the bases are the same and we are multiplying, we add the exponents
r ^2 • r^1 • r^ 5
r^(2+1+5)
r^(8)
The base of the right triangle is 6 cm long.
The formula to find the area of a right triangle is height times base divided by 2. Therefore the formula to find the base of the right triangle using area and height is area divided by height times 2
b = (A/b) * 2
b = (33/11) * 2
b = 3 * 2
b = 6
Answer:
6 knots
Step-by-step explanation:
Let the speed be v knots
then time taken to cover 500 M = 500 / v hrs
fuel consumption /hr = 216 + 0.5v^3
let F be the fuel consumption for trip
= [500/v][216 + 0.5v^3]
= 500[216/v + 0.5v^2]
dF/dv = 500[ - 216/v^2 + v]
d^2F/d^2v = 500[432/v^3 + 1] , i.e. +ve
so setting dF/dv will give a minima
500[ -216/v^2 + v] = 0
or v = 216/v^2
or v^3 = 216
solving, we get v = [216]^(1/3) = 6 knots
|7-10| = 3 (absolute value), then multiply to the negative sign. answer:-3
