Q = p(r + s)
Use the distributive property
Q = pr + ps
Q = p x r + p x s
Q = p x p + r x s
Q = p^2 + rs
Subtract rs from both sides
Q - rs = p^2
Square root both sides
sqrt Q - rs = p
Answer:
3520 ft/min
Step-by-step explanation:
40 mi/h = (40 mi/h)×(5280 ft/mi)×(1 h)/(60 min) = 3520 ft/min
_____
Each conversion factor has a value of 1 (numerator = denominator), so changes the units without changing the speed.
let's recall that an equilateral triangle has all interior angles of 60°.
Check the picture below.
so as you can see, 2√3 = x = r, namely the radius of the circle.
Substitute 2 into x in the equation so f(x)= 5x2 -12 = -2 so it’s C = -2
Answer:
12
Step-by-step explanation:
its just 12
