Answer:
D)The equation is f(x)=3x^2−9x+3, and the parabola opens upward.
The surface area is 63 inches.
7x9= 63 inches
The final temperature is the sum of the initial temperature and the change in temperature. The initial temperature is 102°F. The change in temperature is -3°F.
Operation:
Tf = Ti + ΔT = 102°F + (-3°F) = (102 - 3)°F = 99°F
Answer:
68.8cm^2
Step-by-step explanation:
A trapezoid=h/2(b1+b2)
A trapezoid=6.4/2(12.9+8.6)
A trapezoid=3.2(21.5)
A trapezoid=68.8cm^2
