This graph is non-proportional because the line does not pass through the origin

Answer: a=126, b=134, c= 110, d=146, e=46

Step-by-step explanation:

so for a you take 180-54 and that gives you A

for b you take 33,70,and A(126) and add them together then subtratct by 360 and you get b for d you take 180-33 and get 146 for c you take 180-70 and get 110 and for e you take 180 - 134(B) and you get tha answer to e

Fill out the following chart to find the temperatures for t = 12 (noon) and t = 24 (midnight). (2 points: 1 point for each row)

sergey [27]

Part.1
Given equation:
C(t) = -0.30 (t – 12)² + 40

For t = 0
C(t) = -0.30 (0 - 12)² + 40
C(t) = -0.30 (-12)² + 40
C(t) = -3.2

For t = 12 (noon)
C(t) = -0.30 (12 - 12)² + 40
C(t) = -0.30 (0)² + 40
C(t) = 40

For t = 24 (midnight)
C(t) = -0.30 (24 - 12)² + 40
C(t) = -0.30 (12)² + 40
C(t) = -0.30 × 144 + 40
C(t) = - 43.2 + 40
C(t) = -3.2

Part.2
Graph of the equation is given in the attachment.

Part.3
C(t) = –0.30(t – 12)² + 40
F(t)=9/5C(t)+32

Substituting the values:
F(t)=9/5{–0.30 (t – 12)² + 40}+32
F(t) = -0.54 (t – 12)² + 72 + 32
F(t) = -0.54 (t – 12)² + 104
