Find the surface area of her notebook.
30 + 30 + 20 + 20 = 100
Now find the surface area of the square stickers.
2 + 2 + 2 + 2 = 8
So this is the surface area of one square, now multiply it by 8.
8 * 7 = 56
This is the surface area of all the stickers, now subtract it to the surface area of the notebook:
100 - 56 = 44
So 44 centimeters of the notebook cover will still be showing.
Answer: 3rd option : Angle 2 and 7
Step-by-step explanation:
Alternate exterior angles are located on the outside of the parallel line on opposite sides.
Therefore, the alternate exetrior angles are 1 and 8 and 2 and 7.
Since there is no option for angle 1 and 8, the correct answer is the 3rd option --> Angle 2 and 7.
Answer:
5.2 seconds
Step-by-step explanation:
We want to determine the value of x when h(x) = 0
:
-16x^2 +83x + 4 = 0
:
use quadratic formula to determine the value for x
:
x = ( -83 + sqrt(83^2 - 4*(-16)*4) ) / (2*(-16) = −0.047753182
:
x = ( -83 - sqrt(83^2 - 4*(-16)*4) ) / (2*(-16) = 5.235253182
:
we want the positive value for x since time runs forward
:
the ball hung in the air for approx 5.2 seconds
