Step-by-step explanation:
Answer: f(4) = 21
Step-by-step explanation:
2(4)^2-11
4^2 = 16
2(16)-11
Multiply 2 and 16
32 - 11
Subtract
21
Using the Law of Sines (sina/A=sinb/B=sincC for any triangle)
sinc/28=sin90/53 (sin90=1) multiply both sides by 28
sinc=28/53 take the inverse of sin (arcsin) of both sides
c=arcsin(28/53)°
c≈31.89° (to nearest hundredth of a degree)
So it is obvious that they rounded to nearest tenth of a degree
c≈31.9°
Answer:
2.25 cups
Step-by-step explanation:
There are 5 eights in 40.
1.25 × 5 = 6.25
1.5 × 5 = 7.5
1 × 5 = 5
1 quart = 4 cups
6.25 cups - 4 cups = 2.25 cups
