Answer:
At the time of launch height of the object was 60 meters.
Step-by-step explanation:
An object was launched from a platform and its height was modeled by the function,
h(x) = -5x² + 20x + 60
Where x = time or duration after the launch
At the time of launch, x = 0
So, by putting x = 0 in this equation,
h(0) = -5×(0) + 20×(0) + 60
h(0) = 60
Therefore, at the time of launch height of the object was 60 meters.
Answer: $25 spent
Step-by-step explanation: the boy spent $15/total.
15/total=3/8
Divide by common factor: $15/3=$5 (1/8 total money
$5x8=$40
$40-$15=$25 spent
All triangles have a measurement of 180 degrees. Therefore, we can use this information to make an equation to find the value of angle B.
Angle B = 180 - (28 + 36)
Angle B = 180 - 64
Angle B = 116
So, angle B is equal to 116 degrees.
36% is the answer to the question
Answer: b.not enough info
Step-by-step explanation:
Corresponding angles of congruent triangles are congruent, so
However, we don't have all 3 interior angles of either triangle, so we cannot conclude anything.
