Answer:
Step-by-step explanation:
Bottom triangle
Area = b * height
b = 4 + 4 = 8 cm
h = 5.75
Area = 1/2 * 5.75 * 8
Area = 23 cm^2
Trapezoid
b1 = 8
b2 = 4
h = 2
Area = (b1 + b2)*h/ 2
Area = (8 + 4)*2 /2
Area = 12
Total area = 23 + 12
Total area = 35
Step-by-step explanation:
Substituting into vertex form, the equation is:
y = a(x-3)^2 + 5
The y-intercept is when x=0, so substituting this in,
1=a(0-3)^2 + 5
-4 = 9a
a=-4/9
