Divide 900/150 to find the amount of money paid, since 1.00 is paid for every 150 pieces.
900/150=6
The answer is 6.00.
Answer:
cos = adjacent of angle A / hypotenuse
Step-by-step explanation:
cos = adjacent of angle A / hypotenuse . . . . . . . . . . . .
Let's say the Height of the triangle is 4 cm., the Base is 3 cm, and the Hypotenuse is 5 cm. If the top angle was angle A then the value would be 4/5. Because the Height is adjacent to angle A and the Hypotenuse is 5 cm.
Formula of the parabola: (x - h)²<span> = 4p(y - k)
(h,k) is a vertex, </span>(1,-9) is a vertex.
<span>h=1, k= - 9
Substitute h and k into formula </span>(x - h)² = 4p(y - k)
(x - 1)² = 4p(y + 9)
Substitute x and y of the y-intercept
(x - 1)² = 4p(y + 9), x=0,y=-6.
(0 - 1)² = 4p(-6 + 9)
1 = 4p*3
1/3 = 4p, substitute value of 4p into (x - 1)² = 4p(y + 9).
(x - 1)² = 1/3(y + 9)
x²-2x+1=(1/3)y + 3
(1/3)y = x²-2x-2
y = 3x² - 6x -6
x-intercepts, is values of x when y=0.
3x² - 6x -6 = 0
x²-2x-2=0
We will find values of x using formula.
