Step-wise-StepExplanation:
Complementary angles are angles that add upto 90°. They need not to be adjacent Always
According to question, Angle P = 2(Angle M) + 3°. And they add upto 90°.
⇒ Angle P + Angle M = 90°
⇒ 2(Angle M) + 3° + Angle M = 90°
⇒ 3 Angle M + 3° = 90°
⇒ 3 Angle M = 87°
⇒ Angle M = 29°
Then, Angle P = 2(29°) + 3° = 61°. Hence, the two complementary angles are 29° and 61°.

Step-by-step explanation:
Line segments with the same length are said to be __________.
41/3
(B) f(t) = 4(t − 1)2 + 3; the minimum height of the roller coaster is 1 meter from the ground
(C) f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 2 meters from the ground
(D) f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 1 meter from the ground
The function is a parabola, and the problem asks to transform the equation into f(t)=a(x-h)2 + k
Given f(t) = 4t2 -8t +7
= (4t2 - 8t + 4) + 7 - 4
=4 (t2 - 2t + 1) + 3
= 4 (t-1) 2 +3
This removes C and D from the viable choices.
Differentiating the f(t),
f’(t) = 8t – 8, the maximum/minimum value occurs at f’(t) = 0
0 = 8t – 8
t = 1
determining if maximum or minimum, f”(t) > 0 if minimum, f”(t) < 0 maximum
f”(t) = 8 > 0, therefore minimum
f(1) =4(1)^2 – 8(1) +7
= 3
Therefore, minimum height is 3.
