Answer:
Andy added 70 to 5 instead of multiplying 70 by 5.
Step-by-step explanation:
We have been given that Mrs.Ruiz bought 5 bags of balloons for a party. Each bag contained 70 balloons. Andy said Mrs.Ruiz bough a total of 75. Andy is incorrect what error did Andy make when calculating the total number of balloons.
To find the total number of balloons in 5 bags, we will multiply number of balloons in each bag by 5.


Therefore, the total number of balloons in 5 bags would be 350 balloons.
Andy added 70 to 5 instead of multiplying 70 by 5.

Answer:
81 m
Step-by-step explanation:
At take off t = 0, substitute x = 0 into h(x)
h(0) = - 3(0 - 3)² + 108 = - 3(9) + 108 = - 27 + 108 = 81 m
Answer:
Step-by-step explanation:
A comlemetery angle is a angel or angles that add up to 90 degrees. They make a right angle. A supplemetry angle is a agle or agles that add up to 180 degrees and make a strate line.
F ` ( x ) = ( x² )` · e^(5x) + x² · ( e^(5x) )` =
= 2 x · e^(5x) + 5 e^(5x) · x² =
= x e^(5x) ( 2 + 5 x )
f `` ( x ) = ( 2 x e^(5x) + 5 x² e^(5x) ) ` =
= ( 2 x ) ˙e^(5x) + 2 x ( e^(5x) )` + ( 5 x² ) ` · e^(5x) + ( e^(5x)) ` · 5 x² =
= 2 · e^(5x) + 10 x · e^(5x) + 10 x · e^(5x) + 25 x² · e^(5x) =
= e^(5x) · ( 2 + 20 x + 25 x² )
