-2 times -2 will give you 4 or (-2 x -2=4)
-8 times -2 will give you 16 or (-8 x -2=16)
16 times -2 will give you -32 or (16 x -2=-32)
Answer:
<em>B. 74.89</em>
Step-by-step explanation:
sin(27) = 34/x
sin(27) → 0.45399049974 ≈ 0.45399
x = 34/0.45399
x = 74.89

1. The solution for the equation is -16t² + 64t > 0
2. The interval notation for the equation is (0, 4)
Given,
The height of the building = 400 feet
A ball is thrown straight up from the top of the building.
The initial velocity of the ball = 64 feet/second
The height of the object is modeled by, s(t) = -16t² + 64t + 400
1. Solution for the equation:
s(t) > 400
So,
-16t² + 64t + 400 > 400
Add -400 to both sides
ie, -16t² + 64t + 400 - 400 > 400 - 400
We get,
-16t² + 64t > 0
2. Now find the interval notation for the equation:
-16t² + 64t > 0
Here, 64/16 = 4
So,
-16t (t - 4) > 0
Now,
t = 0 and t - 4 = 0
The interval notation for the equation is (0, 4)

Answer:
Extrapolation
Step-by-step explanation:
Given the regression equation :
pushups = 0.72 + 7.62 miles
Determining the Number of miles a person who does 24 push-ups should be able to run is an example of extrapolation, this is because we are making a prediction into the the future or outside our data based on the available information. Regression equations are used for extrapolation (making future predictions). Interpolation on the other hand makes estimation within the limit of the data usually between two known values.
