Help pleaseeee ??????!!!!! I choosed the Death Valley one

1.) C(t) = -0.30(t - 12)^2 + 40
for t = 12: C(12) = -0.30(12 - 12)^2 + 40 = -0.30(0)^2 + 40 = 40°C
For t = 24: C(24) = -0.30(24 - 12)^2 + 40 = -0.30(24 - 12)^2 + 40 = -0.30(12)^2 + 40 = -0.30(144) + 40 = -43.2 + 40 = -3.2°C

4.) F(t) = 9/5 C(t) + 32
for C(t) = 40°C: 9/5 (40) + 32 = 72 + 32 = 104°F
for C(t) = -3.2°C: 9/5(-3.2) + 32 = -5.76 + 32 = 26.24°F

5.) F(t) = 9/5 C(t) + 32 = 9/5 (-0.30(t - 12)^2 + 40) + 32 = -0.54(t - 12)^2 + 72 + 32 = -0.54(t - 12)^2 + 104

Answer:

  multiply by 3 and divide by 2 to get 6x -y = 12.

Step-by-step explanation:

A standard form equation has mutually prime integers for coefficients, and the leading one is positive. We can get that here by multiplying by 3 (to eliminate the denominator) and dividing by 2 (to remove that common factor). The result is ...

  4(3/2)x -(2/3)(3/2)y = 8(3/2)

  6x -y = 12

Anddd Similar traingles for one more time.

Here,
RQ/RP = RS/RT = QS/PT = 1/2


Using the values of QS and PT will give,

\frac{y}{y + 46}  =  \frac{1}{2} \\  \\  2y =y + 46 \\  \\  y = 46


Therefore y= 46 units.
