Because the parabola opens down and the vertex is at (0, 5), we conclude that the correct option is:
y = -(1/8)*x² + 5.
<h3>
Which is the equation of the parabola?</h3>
The relevant information is that we have the vertex at (0, 5), and that the parabola opens downwards.
Remember that the parabola only opens downwards if the leading coefficient is negative. Then we can discard the two middle options.
Now, because the parabola has the point (0, 5), we know that when we evaluate the parabola in x = 0, we should get y = 5.
Then the constant term must be 5.
So the correct option is the first one:
y = -(1/8)*x² + 5.

Answer:
A. P = 72 feet, A = 300 square feet
Step-by-step explanation:
✔️Perimeter = sum of all sides of the polygon = 15 + 16 + 17 + 8 + 16 = 72 ft
✔️Area of the polygon = area of a trapezoid = ½(a + b)h
Where,
a = 16 ft
b = 16 + 8 = 24 ft
h = 15 ft
Substitute
Area = ½(16 + 24)15
Area = ½(40)15
Area = 300 ft²
Answer:
A=1/2bh
Step-by-step explanation:
The area A of a triangle is given by the formula A=1/2bh where b is the base and h is the height of the triangle.
So for example if you got that the base of the triangle is 12 and the height is 14 you would plug it in like this:
A=1/2(12)(14)
A=6(14)
A=84
Answer:
x = 30
Step-by-step explanation:
6(x-2)=8(x-9)
6x-12=8x-72
6x-6x-12+72=8x-6x-72+72
60=2x
x = 30
check:
6(30-2)=8(30-9)
6(28)=8(21)
168=168 ✅
