Answer:
D) Quadratic
Step-by-step explanation:
A function is graphed on a coordinate grid.
- As the domain values approach infinity, the range values approach infinity.
Domain: If 
then
Range: 
- As the domain values negative infinity, the range values approach infinity.
Domain: If 
then
Range:
We need to choose correct option which follows given domain and range.
Only quadratic function will follow the rule because it has even degree polynomial.
Quadratic function: 
Degree = 2 and leading coefficient is positive.
Domain: 
Range: 
Hence, D is correct option.
Answer:
x=12, y=30
Step-by-step explanation:
to find x:
in a equilateral triangle, all three sides are congruent, so:
4x-4=3x+8
x-4=8
x=12
to find y:
in an equilateral triangle, all the angles are 60°, so:
2y=60
y=30°
<h2>135 cubic feet of concrete are required to create the platform.</h2>
Step-by-step explanation:
The dimension of lower step is 6 ft× 3 ft× 1.5 ft
and the dimension of upper step is 6 ft ×(9-3)ft × (1.5+1.5)ft = 6 ft × 6 ft ×3 ft
Therefore concrete are required to make lower step = (6×3×1.5) cubic feet
= 27 cubic feet
and concrete are required to make upper step = (6×6×3) cubic feet
=108 cubic feet
<h3>∴(108+27) cubic feet =
135 cubic feet of concrete are required.</h3>
