Answer:
D) 1980 to 2000
Step-by-step explanation:
Finding the average rate of change in each interval to determine the greatest one.
Production per interval
1950-1960 = = 10 million
1960-1970 = = 20 million
1970-1980 = = 30 million
1980-2000 = million
Rate of change (1950-1960)=
Rate of change (1960-1970) =
Rate of change (1970-1980)=
Rate of change (1980-2000)=
∴ rate of change between 1980 to 2000 is 126.78%
Answer:
4.
Step-by-step explanation:
(sec α - tan α)(sec α + tan α) = sec^2 α - tan^2α
But sec^2 α = 1 + tan^2 α so
sec^2 α - tan^2α = 1 + tan^2 α - tan^2α
= 1
so 1 = (sec α - tan α)(sec α + tan α) = 1/4 * x where x is sec α + tan α
1/4 * x = 1
x = 4.
Answer:
Step-by-step explanation:
The bases of a triangular prism are equilateral triangles, since they have equal sides: 5, 5, and 5
yes, since if all lateral faces are rectangles, rectangles are formed from 4 perpendicular segments, thus, if all edges of the lateral faces are perpendicular, then they are rectangles
Answer:
x < 8
Step-by-step explanation:
Given
x + 4 < 12
Isolate x on the left side by subtracting 4 from both sides
x < 8 ← is the solution
(x+20)-(x+1)=18
x+20-x-1=18
19=18
It has no solution
