A=h(b+c)
A/h=b+c
b=(A/h)-c
Answer: b=(A/h)-c
Answer:
144
Step-by-step explanation:
Because when you find the area of a square, the sides of a square is the same, you just multiply 12 and 12, because area is just 2 sides of the shape! Your welcome :D
0.1[x+250]=5000
10(0.1[x+250]=5000
1[x+250]=50,000
x+250=50,000
-250 -250
x = 49,750
Answer:
= 6, 9
Step-by-step explanation:
To find the midpoint , we use the formula
midpoint = (x1+x1)/2, (y1+y2)/2
= (2+10)/2, (6+12)/2
= 12/2, 18/2
= 6, 9
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.
