Your answer is C
Step-by-step explanation:
Multiply -33 x 11
Step-by-step explanation:
(a○b)(x) is the same as a(b(x)).
it is really that simple.
first you calculate the result of the inner function, and then that result is the input for the outer function.
that's it.
so,
(w○u)(2) = w(u(2))
u(2) = -2 -1 = -3
w(-3) = 2×(-3)² + 1 = 2×9 + 1 = 19
so, 19 is the first answer.
(u○w)(2) = u(w(2))
w(2) = 2×2² + 1 = 2×4 + 1 = 9
u(9) = -9 - 1 = -10
so, -10 is the second answer.
A cylinder of radius r cm and height h cm has a curved surface area A cm². Where –
a) We are asked to find formula for h.


First, overturn the equation


Divide both sides by 2πr






b) Again, we are given –
- Curved surface area, A = 93 cm²
- Radius, r = 2.5 cm
- π = 3.1

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━










- Henceforth, height of the cylinder is 6 cm.
Answer:
$45
Step-by-step explanation:
300/100 = $3 = 1%
$3 x 5 = $15 = 5%
$15 x 3 years = $45
