Answer:
6
Step-by-step explanation:
your profile says you're 22 but I find that painfully challenging to believe. She knits 5 scarves in 2 hours. Divide 10 by 2, you get 5. 5x5 is 25. It's C. You shouldn't need help. This is sad.
Answer:
f(1) = 2
Step-by-step explanation:
To find f(1), substitute x = 1 into f(x), that is
f(1) = 1² + 3(1) - 2 = 1 + 3 - 2 = 2
Answer:
x = 7.33
Step-by-step explanation:
3x - 15 = 7
3x = 7 + 15
3x = 22
x = 7.33
Answer: Area of the shaded region is 6.867 square cm
Step-by-step explanation:
The shaded area corresponds to the difference of the area of the rectangle and the area of the semicircle.
Area of the rectangle = 4 times 8 = 32 cm^2
Area of the semicircle = 0.5 * pi * r^2 (where r is the radius, i.e., half of the diameters, i.e., 4 cm). So Area = 0.5*pi*4^2 = 25.133 cm^2
The difference: 32 - 25.133 = 6.867 cm^2 (area of the shaded region)
