Answer:
Second graph only.
Step-by-step explanation:
The standard equation of a parabola is ax^2+bx+c where a,b and c are coefficients.
If the coefficient of (a) is positive then the parabola is concave upwards (as in picture 1)
If the coefficient of (a) is negative then the parabola is concave downwards as in picture 2.

Answer:
x = 4
Step-by-step explanation:
2(x/4 + 8) = 18
First: Distribute 2 into "x/4 + 8".
2x/4 + 16 = 18
2x/4 = 18 - 16
1x/2 = 2
x/2 • 2 = 2 • 2
x = 4
P.S "•" means to multiply.

Answer:
<h2>
17.6ft²</h2>
Step-by-step explanation:
The formula for calculating the surface area of a triangular prism is expressed as shown below:
SA= bh + pH
b= base of the triangle
h- height of the triangle
p= perimeter of the triangle
H= height of the prism
Given b = 1foot
h = 2feet
perimeter of the triangle = sum of all its sides = 1ft + 2ft + 2.2ft
p = 5.2ft
H = 3ft
Substituting the values into the formula for finding the surface area:
SA = 1(2)+5.2(3)
SA = 2+15.6
SA = 17.6ft²
The surface area of the triangular prism is 17.6ft²
