Which function has the greatest maximum range value?
The function f(x) is a sine graph, and the function with the greatest maximum range value is the function f(x)
How to determine the function with the greatest maximum range value?From the complete question (see attachment), the functions are given as:
Functions f(x) and g(x)
The maximum range value of these functions is their maximum output value
Function f(x) has a maximum range value of 3, while function g(x) has a maximum range value of -2
3 is greater than -2
Hence, the function with the greatest maximum range value is the function f(x)

Find the measure of angle
Answer:
112 degrees
Step-by-step explanation:
180-68=112
Since they are supplementary they form a straight angle, or 180 degrees so the angle AED is 112
Answer:
112
Step-by-step explanation:
∠AED and 68 are Linear pair angles.
That is their sum will be equal to 180,
∠AED + 68 = 180
∠AED = 180 - 68
∠AED = 112

Step-by-step explanation:
Area of Rectangle: Area = Length * Width
Given information:
Area = 22 in^2Length = 2x - 1Width = x - 4Put that into the Formula.
Area = Length * Width
22 in^2 = (2x - 1) * (x - 4)
Solve.
22 in^2 = (2x - 1) * (x - 4)
[tex]22 = (2x^2 - 9x + 4)\\2x^2 - 9x - 18 = 0[/tex]
Factor it.
(2x^2 - 9x - 18) = 0
(2x + 3)(x-6) = 0
[tex]x=-\frac{3}{2} ,6[/tex]
Plug that into the Length and Width to find the actually Length and Width.
Length:
[tex]2x - 1\\2*-\frac{3}{2}-1\\ -3-1\\-4\\[/tex]
Width:
[tex]x - 4\\-\frac{3}{2}-4\\ -\frac{11}{2}[/tex]

The area of the smallest circle with radius 3 is 28.27 unit². The area of the yellow ring and white ring is 28.27 unit² and 56.55 unit².
What is the area of the circle?The area of the circle is the space occupied by it. It can be given as,
[tex]A=\pi r^2[/tex]
Here (r) is the radius of the circle.
In this diagram, three concentric circles' rectangle.
Point C lies in the middle have their centers at O, and OABC is a lies on the outer circle. Point A lies on the inner circle, and point B the smallest circle. 1. The area of the smallest circle-The radius of the smallest circle is 3.
[tex]r_1=3\rm\unit[/tex]
Thus, the area of it is,
[tex]A=\pi (3)^2\\A=28.27\rm\; unit^2[/tex]
2. The area of the yellow ring.Let suppose the mid-point of the rectangle is D. Here, OB is the diagonal of the rectangle in which,
[tex]OD=BD[/tex]
The radius of the yellow ring's outer face from point O is,
[tex]r_3=OD+BD\\r_3=OD+OD\\r_3=2OD\\[/tex]
OD is the radius of the small circle, which is 3 units long. Thus,

f(x)=−2x+16
g(x)=4x+10
please give me the intersection points
Answer:
(1, 14)Step-by-step explanation:
The intersection is when both functions have same coordinates
f(x) = g(x)Substitute to get
- 2x + 16 = 4x + 104x + 2x = 16 - 106x = 6x = 1The y- coordinate is
y = - 2(1) + 16 = -2 + 16 = 14So the intersection point is (1, 14)
Answer:
(1, 14)
Step-by-step explanation:
Given functions:
[tex]\begin{cases}f(x)=-2x+16\\g(x)=4x+10\end{cases}[/tex]
Substitute the function notation for y to create a system of equations:
[tex]\begin{cases}y=-2x+16\\y=4x+10\end{cases}[/tex]
To find the points of intersection of the given functions, solve the system of equations.
Multiply the first equation (function f(x)) by 2:
[tex]\implies 2y=-4x+32[/tex]
Add this to the second equation (function g(x)) to eliminate x:
[tex]\begin{array}{r l}4x+10 & = y\\+ \quad -4x+32 & = 2y\\\cline{1-2} 42 & = 3y\end{array}[/tex]
Solve for y:
[tex]\implies 3y=42[/tex]
[tex]\implies y=14[/tex]
Substitute the found value of y into one of the equations and solve for x:
[tex]\implies 4x+10=14[/tex]
[tex]\implies 4x=4[/tex]
[tex]\implies x=1[/tex]
Therefore, the point of intersection of the given functions is (1, 14).

Question 14 of 15
Len wants to learn more about red kangaroos. Which of the following is a
statistical question Len could ask?
O A. How tall is a red kangaroo?
O B. Are there red kangaroos in Asia?
• C. Are red kangaroos an endangered species?
O D. What iS the tallest red kangaroo ever recorded?
Answer:
A statistical question Len could ask is "How tall is a red kangaroo?"
Step-by-step explanation:
A statistical question is something that we can ask and test hypotheses about using collected data. There will not be a specific answer, but rather multiple answers and we can average them in a sampling distribution.
Let's examine each question:
"How tall is a red kangaroo?"
There is not a specific height for each kangaroo, so we can take the averages of many different samples and find the "true mean" in the sampling distribution. This is a good example of a statistical question because data can be collected on red kangaroos and means can be calculated."Are there red kangaroos in Asia?"
"Are red kangaroos an endangered species?"
What is the tallest red kangaroo ever recorded?"
These are all examples of non-statistical questions. They are "yes" or "no" questions, and we cannot take multiple samples to determine the answer. Rather, there is a single answer that we do not need to test hypotheses or perform any statistical calculations.(50 points + Brainliest) Create an equivalent expression that includes a set of parentheses that make the value of the expression 13.

Step-by-step explanation:
find an equation and the slope of the line that passes through (5,2) and is perpendicular to the x-axis
y=2; The slope is undefined.
x=5; The slope is 0.
y=2; The slope is 0.
x=5; The slope is undefined.
Solution: x = 5; The slope is undefined.
The slope that is perpendicular to the x-axis is undefined.
Explanation:
Given point: (5,2)
Since the line is perpendicular to the x-axis, then, the line is vertical.
Hence, x = 5
Answer:
x = 5, the slope is undefined
Step-by-step explanation:
Hello!
To be perpendicular to the x-axis, the line has to intersect at a 90° angle, causing it to be a vertical line with an undefined slope.
This removes the two middle options, as they have a slope of 0.
Consequently, looking at the two options, y=2, and x=5, y=2 would give us a parallel line to the x-axis, as we are drawing a line through all points with a y-coordinate of 2.
The correct option is x=5.

Which equation is equivalent to 7(r + 4) - 3?
7*r+7*4*3
7*r*7*4-3
7*r+7*4-3
7*r+7*4
Answer: Choice C
7*r+7*4-3
=========================================================
Reason:
We use the distributive property to go from 7(r+4) to 7*r+7*4
Multiply the outer 7 by each term inside.
Then the -3 tags along without any changes to it
So we go from 7(r+4) - 3 to 7*r+7*4 - 3
This can be simplified further to 7r+25, but your teacher has chosen not to simplify at this time.

Answer:
The equation of the line in point-slope form is y - 2 = -4(x + 5).

Use the point-slope equation: [tex]y-y_1=m(x-x_1)[/tex].
Substitute the point (-5, 2) and the slope m = -4 into the equation.
