Answer:
x = 85
Step-by-step explanation:
x - 20 = 62
add the 20 on both sides x - 20 = 62
+20 +20
add 62+20 to get 85 x = 85
Answer:
27ft^3
Step-by-step explanation:
3^3 is 27
Answer:
Step-by-step explanation:
For a rectangular prism, a plane intersecting this prism produces a two dimensional figure as its cross section and in this case the cross section is a rectangle.
For a triangular prism, a plane intersecting this prism produces a two dimensional figure as its cross section and in this case the cross section is a triangle.
So first, we want to find how much in total did his elevation change. So we want to subtract the him starting from 6 feet below sea from the 98 feet below sea level, to get 92 feet.
Now, since he descended in four equal intervals, we can just divide 92 into four equal parts, or divide by 4, to get 23 feet.
So the diver's change in elevation in each interval was (negative?) 92 feet.
Answer:
x^2 - 4x + 29 = 0
Step-by-step explanation:
Complex roots occur as conjugate pairs.
So the other root will be 2 - 5i.
First write the equation it in factor form:-
(x - (2 + 5i)) (x - (2 - 5i) = 0
(x - 2 - 5i)(x - 2 + 5i) = 0 Now expand:-
x^2 - 2x + 5ix - 2x + 4 - 10i - 5ix + 10i - 25i^2 = 0
x^2 -2x - 2x + 4 - 25*-1 = 0
x^2 - 4x + 29 = 0 (answer)
