Answer:
Rate of Change : 8 / π
Step-by-step explanation:
To determine this rate of change, we have to first consider the points at x = 0 and x = π / 2.
When x = 0, f( x ) = - 4,
When x = π / 2, f( x ) = 0
Remember that rate of change is represented by a change in y / change in x. Therefore,
( 0 - ( - 4 ) ) / ( π / 2 - 0 ),
( 0 + 4 ) / ( π / 2 ),
4 / π / 2 = 8 / π
Therefore the rate of change from x = 0 ➡ x = π / 2 will be 8 / π.
Answer:
the answer of it is 35.75
Step-by-step explanation:
Answer:
twice
Step-by-step explanation:
to find expected value multiply probablility and number of events
0.40 times 5 = 2.0
Since both rectangles are similar, the following ratio must be fulfilled:
By multiplying both sides by 14, we get
and by subtracting 9 to both sides, we have
Therefore, the answer is 12.
Answer:
The answer is B
Step-by-step explanation:
75 + x = 90
First, Virginia had to write an equation to solve for x.
75 - 75 + x = 90 - 75
Second, Virginia used the subtraction property of equality to isolate x.
x = 15
Third, "x = 15" was the answer Virginia got after subtracting 90 and 75.
75 + 15 = 90
Finally, she had to verify her answer
