Find the measure of angle AEF in the figure below enter only the number
Answer:
60
Step-by-step explanation:
The middle is a straight angle, which is 180 degrees, and FEB is 120 degrees. 180 - 120 is 60
The measure of the angle AEF will be equal to 60°.
What is coordinate geometry?A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
The supplementary angles are the angles having the sum of the angles as 180 degrees.
The middle is a straight angle, which is 180 degrees, and FEB is 120 degrees.
The measure of the angle AEF is,
AEF = 180 - 120
AEF = 60°
Therefore, the measure of the angle AEF will be equal to 60°.

If f(x) = 2x - 4, find f(3)
Answer:
f(3) = 2
Step-by-step explanation:
f(x) = 2x - 4 when f(3). In other words substitute x with 3 to solve.
f(3) = 2(3) - 4
f(3) = 6 - 4
f(3) = 2

The same garden shop sells mulch according to the equation y = 20x, where y represents the cost in dollars, and x represents the number of cubic yards of mulch. Which statement is true of the cost of topsoil and mulch?
Answer:
20 = cost per mulch of cubic yards sold
Step-by-step explanation:
Given:
y = 20x
Where,
y = the total cost in dollars
x = the number of cubic yards of mulch
20 = cost per mulch of cubic yards sold
The only untrue statement is that the cost of topsoil and mulch is 20

8. The graph below represents the path of a golf ball.
The Path of a Golf Ball
Part A: The above graph is (circle one) linear/nonlinear.
Part B: Is the above graph a function? Explain.
Part C: What is the y-intercept and what does the y-intercept
representa
Part D: What is the solution to this graph and what does it represent in this
situation?
Answer:
Part A: Non linear
Part B: Yes
Part C: The y-intercept is (0, 0), represent the starting height level of the golf ball
Part C: The solution are the points (0, 0) and (100, 0) which are the points at which the golf ball touches the ground
Step-by-step explanation:
Part A: The shape of the path of the increase in the height of the the golf ball as it moves in increasing horizontal distance from the starting point is hat of a parabola
Part B: The graph is a function because each value of the independent variable, distance (ft.) maps to exactly one value of the dependent variable, elevation (ft.)
Part C: The y-intercept represents the starting or initial value of the function, where x = 0. It represents the height from which the golf ball motion path starts
Part D: The solution represents the values of the x-intercept at which the elevation is the y = 0.

what is the slope of the line that passes through the points (-7,-7) and (-7.1)
Answer:
Undefined
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1)
Plug in the two points:
(y2 - y1) / (x2 - x1)
(1 + 7) / (-7 + 7)
8/0
= undefined
So, the slope is undefined, since you cannot divide by zero.
The slope of the lines that passes through the points (-7,-7) and (-7.1) is an infinite slope.
Slope equation:The slope formula is described as follows:
m = y₂ - y₁ / x₂ - x₁Therefore,
x₁ = -7
x₂ = -7
y₁ = -7
y₂ = 1
m = 1 - (-7) / -7 - (-7)
m = 1 + 7 / -7 + 7
m = 8 / 0
m = infinity
The slope is an infinite slope. Therefore, it is a vertical line.

what is 0.98989898 with bar notation
Answer:
the answer would be .735
Step-by-step explanation:
Answer:
[tex]\frac{98}{99}[/tex]
Step-by-step explanation:
We require to create 2 equations with the repeating value (0.989898... )
placed after the decimal point.
let x = 0.989898.... → (1) ( multiply both sides by 100 )
100x = 98.9898..... → (2)
Subtract (1) from (2) thus eliminating the repeating decimal
99x = 98 ( divide both sides by 99 )
x = [tex]\frac{98}{99}[/tex]
Thus
0.989898... = [tex]\frac{98}{99}[/tex] as an exact fraction
