Step-by-step explanation:
Key : Plug in the numbers given in the parenthesis into the x values of the corresponding functions.
f(1/2) = 1/ 1/2 - 4 = 1/-7/2 = -2/7
g(1/2) = 1/1/2 - 2 = -3/2
f(-1/4) = 1/-1/4-4 = 1/-17/4 = -4/17
g(-1/4) = 1/-1/4 - 2 = 1/-9/2 = -2/9
Use 1/4 cups of rolled oats becuase 1/3*3/4 = 1/4
We know that formular for volume of pyramid=area of base ×height
the area of the base is 1/2×base×height
=1/2×15×14
=105cm²
the given volume is 270cm³
∴height=volume÷base area
=270cm³÷105cm²
=
=
You need to show the data above
Area of triangle ABC can be found using the formula ¹/₂ × b × c × sin (A)
Substitute b = 9, c = 7, and m∠A = 66° into the formula gives
Area = 9 × 7 × sin 66° = 57.55
ANSWER: D
