Answer:
-203
Step-by-step explanation:
We know that by formula
p^3 – q^3 = (p – q) (p^2 + pq + q^2 ) -------(1)
(p-q)^2 = p^2 -2pq +q^2 --------(2)
Solving eq(1)
(-7)^2 = p^2 -2(-10) +q^2
49 = 10 +p^2 + q^2
p^2 + q^2 = 39--------(3)
Given:
p-q = -7
pq = -10
Put all given values and eq(3) in eq(1)
p^3 - q^3 = (-7) (39-10)
p^3 - q^3 = (-7) (29)
p^3 - q^3 = -203
Answer:
x = 40 * 
meters
Step-by-step explanation:
You have a 30-60-90 right triangle in this situation.
the height of this triangle is 40 meters
the opposite angle is 30 degrees.
use the tangent.
let x = distance between boat and cliff
tan 30 = 40/x
1/root (3) = 40/x
x = 40 * meters
$82.87. You just add the first three to the starting price and subtract the last one
