A triangular bandana has an area of 78 square inches. The height of the triangle is 9 3 4 inches. Enter and solve an equation to find the length of the base of the triangle. Use b to represent the length of the base. An equation to find the length of the base of the triangle is 78= The length of the base of the triangle is inches.
Area of triangle = 1/2 x base x height:
78 = 1/2 x base x 9 3/4
Multiply both sides by 2:
156 = base x 9 3/4
Divide both sides by 9 3/4:
Base = 16 inches

The functions (f.g)(x) and (g.s)(x) are illustrations of composite function
The values of the composite functions are:
(fg)(x) = -6x^2 + 31x - 40 and (gs)(x) = -8x^3 + 38x^2 -49x+ 10
How to determine the equation of the composite functionThe equation of the functions are given as:
f(x) = 3x - 8
g(x) = -2x + 5
s(x) = 4x^2 - 9x + 2
.
The composite functions are calculated using:
(fg)(x) = f(x) * g(x)
So, we have:
(f g)(x) = (3x - 8) * (-2x + 5)
Evaluate the product
(fg)(x) = -6x^2 + 15x + 16x - 40
Evaluate the like terms
(fg)(x) = -6x^2 + 31x - 40
Also, we have:
(gs)(x) = g(x) * s(x)
So, we have:
(gs)(x) = (-2x + 5) * (4x^2 - 9x + 2)
Expand
(gs)(x) = -8x^3 + 18x^2 -4x + 20x^2 - 45x + 10
Collect like terms
(gs)(x) = -8x^3 + 18x^2 + 20x^2-4x - 45x + 10
Evaluate the like terms
(gs)(x) = -8x^3 + 38x^2 -49x+ 10
Hence, the values of the composite functions are:
(fg)(x) = -6x^2 + 31x - 40 and (gs)(x) = -8x^3 + 38x^2 -49x+ 10

I need to buy enough white boards for 172 students and there are 25 in a pack when the pack arrives 12 whiteboards are damaged. How many whiteboards are undamaged?
Answer:
There are 163 whiteboards undamaged.
Step-by-step explanation:
So first we know that 12 are damaged and there are 172 students. So first we need to find out how many whiteboards did you buy without knowing there will be 12 damaged. The answer is 7 because there are 25 per pack. And 7 * 25 = 175. You can't buy less because you rather buy extra rather then not enough. Now knowing that, what is 175 - 12 because 12 was damaged.
175 - 12 = 163.
There are 163 whiteboards undamaged.

To Find;
How many whiteboards are undamaged?
Solution;
we need 172 whiteboard but one pack consist of 25 whiteboards
⇒ 172/25 = 6.88
≈ 7 pack
Total whiteboard we buy
⇒ 7 × 25 = 175
Out of which 12 whiteboard are damaged
↓ Undamaged whiteboard ↓
→ 175 - 12 = 163 ←

Write the equation of the line that passes through the points (-5,1) and (5,8). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (8 - 1) / (5 - (-5))
m = 7/10
y-intercept using slope above and anyone of given point. Let's use (-5, 1):
y = mx + b
1 = 7/10(-5) + b
1 = -35/10 + b
b = 45/10
b = 9/2
Equation of line:
y = mx + b
y = 7/10x + 9/2
Point slope form:
y - y₁ = m(x - x₁)
y - 1 = 7/10(x - (-5))
y - 1 = 7/10(x + 5)

Answer:
x = 52
Step-by-step explanation:
This is a picture of a right angle, which is 90 degrees. We should first make an equation to represent this problem.
(x - 12) + 50 = 90
1. Subtract 50 from both sides of the equation.
(x - 12) = 40
2. Add 12 from both sides of the equation
x = 52

A. Write a rule to describe it the translation.
B. What were the coordinates of the drummer's final position?
Answer:
a) The answer is: (x + a, y + b)
b) The answer is: (-1, -2)
The initial coordinates are:
(x, y) = (-2, -5)
Let's find a and b.
a is a distance in x direction: a = 1
b is a distance in y direction: b = 3
The final position is:
(x + a, y + b) = (-2 + 1, -5 + 3) = (-1, -2)
