I think it would be obtuse triangle
Answer:
1/2x^2 -3
Step-by-step explanation:
The first equation is 1/2x^2 + 1 and since this equation is the first one minus 4 1-4= -3 so you would get this new equation.
104 square yards
The formula for area of a rectangle is length times width.
A = length x width
A = 13 x 8
A = 104
Since the units on each side are yards, the area is in square yards.
The will spend $33.60 (option C) to make the figure out of construction paper, if the construction paper cost $0.10 per square inch.
Step-by-step explanation:
The given is,
Construction paper cost $0.10 per square inch
Pyramid diagram with dimensions
Step:1
Formula to calculate the area of pyramid,
..............(1)
Where,
l - Base length
w - Base width
h - Height of pyramid
From given,
l = 12 inches
w = 12 inches
For height of pyramid,
By using Pythagorean theorem,
.................(2)
For right angle triangle,
Base =
= 6 inches
Equation (2) becomes,




Height = 5.2915 inches
h - 5.2915 inches
Equation (1) becomes,




≅ 336 square inches
Where,
$0.10 per square inch ( from given)
Paper cost of total figure = 336 square inches
= 336 × 0.10
= $ 33.60
Result:
The will spend $33.60 to make the figure out of construction paper, if the construction paper cost $0.10 per square inch.
