Answer:
h = 20 in
Step-by-step explanation:
V = pi * r^ * h
628 = pi x 10 x h
628/(pi x 10) = h
h = 20
1) m=-2
2) C) y=-3/4x -6
3) D) y=2/5x-2
I don't understand 4 nor 5. My apologies.
6) Parallel
C(x) = 4x³+7x²-14x-6
Step-by-step explanation:
Given that the amount of water used in normal days is given by the equation;
W(x) = 5x³ +9x²-14x +9 -----(i)
The amount of decrease in water used is modeled by the equation;
D(x)= x³+2x² +15--------(ii)
To get the function C(x) that models the water used by the car wash on shorter day you subtract equation (ii) from equation(i)
5x³ +9x²-14x +9
- x³+2x² +15
-------------------------
4x³+7x²-14x-6

Answer:
you have to use pythogarus theorem ,if you have to find the answer analytically without drawing the triangle.the theorem states that in a right angled triangle sum of squares of 2 legs of the right angle is equal to the square of hypotenuse.here hypotenuse is 13 whose square is 169.one leg is 5 whose square is 25.so the square of other leg is 169-25 =144.its square root is 12 .so the second leg is 12.
Step-by-step explanation:
4 embroidered uniforms= $5 fee for each 4 embroidered uniform and $25 for each uniform. 5 x 4 = 20. 25 x 4 = 100. 100 + 20= 125. He paid $120 for the embroidered uniform.
