The answer is 10, because 35 divided by 7 is five, five times 2 is ten.
No because he didn't explain it.
Answer:
A:(4,2) B:(1,2) C:(1,3)
Step-by-step explanation:
During a rotation 90 degrees ccw the points go from (x,y) to (-y,x)
The answer to this problem is 'B'.
This is because to find the area of a circle your formula is
A = 3.14•r²
So your first step is
1. Find the radius by dividing the diameter (6) by 2
6/2 = 3 Radius= 3
Now that you have found the radius (3) plug the number in the formula
2. A = 3.14•3²
OR
A = 3.14•3•3
Finally, solve the last step - Find the area
3.14 • 3 • 3 = 28.26
A = 28.26
Answer: 81.2
Step-by-step explanation:
h(t) = -5t² + 40t + 1.2
h(4) = -5(4)² + 40(4) + 1.2 We plug 4 seconds as t, and solve h(4)
h(4) = -80 + 160 + 1.2
h(4) = 80 + 1.2
h(4) = 81.2
