This looks like a cosine function. Cosine can take on any x value and still be defined. That means all real numbers will work. When asked for domain, it really just means what x values are defined for this function. We just said, cosine can take any x value
If you didnt know this was a cosine function, you could just visually see the function goes on to -∞ and +∞. There's no reason for the function to run into a critical point

solve for X: 5/6 = 10/2x-3
x=___
Answers
Answer:
x = 7.5
Step-by-step explanation:
5/6 = 10/2x-3
Solve using cross products
5 ( 2x-3) = 6*10
Divide each side by 5
2x-3 = 6*10/5
2x-3 =12
Add 3 to each side
2x-3+3 = 12+3
2x =15
Divide each side by 2
2x/2 = 15/2
x = 7.5

Triangle DEF has the following characteristics: a right angle and two other angles that have measures of 100° and 10°.
How many different triangles can be drawn with these angle measures?
More than 2 triangles are possible.
No triangle is possible.
Exactly 2 triangles are possible.
Exactly 1 triangle is possible.
Answers
No triangle is possible. The sum of the interior angles of a triangle must be 180°. However, the sum of the given angles is 100° + 10° + 90° = 200°, which is greater than 180°. Therefore, no triangle can be drawn with these angle measures.

Pls help
Answers
The distance between the bottom of the ladder to the bottom of the building is 24 feet.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given that If you place a 28-foot ladder against the top of a 15-foot building,
We need to find how many feet will the bottom of the ladder be from the bottom of the building.
This can be found by using the pythagoras theorem.
Let the ladder be the hypotenuse and wall be the opposite sides of triangle. We need to find the adjacent side.
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides
15²+x²=28²
225+x²=784
x²=784-225
x²=559
Square root on both sides
x=23.64
x=24 feet.
Hence, 24 feet is the distance between the bottom of the ladder to the bottom of the building

What is 0.75 as a fraction?
Answers
Answer:
3/4
Step-by-step explanation:
We would like to find what 0.75 is as a fraction.
Remember that since there are two digits past the decimal point, the denominator will 100.
So, the numerator is 75 and the denominator is 100. We now have:
75/100
We would like to simplify this. Notice that the top and bottom (75 and 100) are both divisible by 25. So divide both by 25:
75 / 25 = 3
100 / 25 = 4
The answer is thus 3/4.

Write an equation of the line that passes through each pair of points.
Make sure it’s an equation with y=mx+b
(-8,-3), (-1,-2)
please provide explanations because i’m studying and point grinding WILL BE REPORTED
Answers
Answer:
\(y = \frac{1}{7} x - 1 \frac{6}{7} \)
Step-by-step explanation:
In y= mx +b, m is the slope and b is the y-intercept.
\(\boxed{slope = \frac{y1 - y2}{x1 - x2} }\)
where (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate
Slope
\( = \frac{ - 3 - ( - 2)}{ - 8 - ( - 1)} \)
\( = \frac{ - 3 + 2}{ - 8 + 1} \)
\( = \frac{ - 1 }{ - 7} \)
\( = \frac{1}{7} \)
Substitute m= ⅐ into the equation:
y= ⅐x +b
To find the value of b, substitute a pair of coordinates into the equation.
When x= -1, y= -2,
-2= ⅐(-1) +b
-2= -⅐ +b
b= ⅐ -2
\(b = - 1 \frac{6}{7} \)
Thus the equation of the line is \(y = \frac{1}{7} x - 1 \frac{6}{7} \).

Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First she found three points on the graph to be (–1, –4), (0, -3), and (2, 5). Next, she determined the rate of change between the points (–1, –4) and (0, -3) to be StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction = StartFraction 1 Over 1 EndFraction = 1. and the rate of change between the points (0, -3) and (2, 5) to be StartFraction 5 minus (negative 3) Over 2 minus 0 EndFraction = StartFraction 8 Over 2 EndFraction = 4. Finally, she concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong? The points (–1, –4), (0, –3), and (2, 5) are not all on the graph. The expressions StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction and StartFraction negative 3 minus (negative 5) Over 2 minus 0 EndFraction both equal 1. She miscalculated the rates of change. Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.

Answer: Slopes are not equal so the function is not linear
Step-by-step explanation:
Slope is change in y/ change in x = y2-y1/ x2-x1
Calculations for (-1, -4) and (0, -3)
slope = -3- -4/0- -1 = 1/1 = 1
Next Calculate the slope between (0,-3) and (2,5)
slope = 5--3/2-0 =8/2=4
Slopes are not equal so the the points are not linear

The median is the middle value in the data set. Since there are five values in the data set, the middle value is the third value, which is 35. Therefore, the median of the data set is 35.
To find the mean, we need to add up all the values in the data set and divide by the total number of values:
(3 + 31 + 35 + 36 + 38) / 5 = 28.6
Therefore, the mean of the data set is 28.6.
the median is always the middle number so the median is 35. hope this helps you to remember in the future

What is the solution set for this system of equations?
4x + y = 13
x − 3y = 0
Answers
Answer:
(3, 1)
Step-by-step explanation:
Pre-SolvingWe are given the following system:
4x + y = 13
x - 3y = 0
We want to find the solution.
We can solve this system with substitution, where we solve one of the variables for the other, then substitute that value into the other equation.
SolvingTo start, we can add 3y to both sides to solve for x.
x - 3y = 0
+3y +3y
____________________
x = 3y
Now, substitute x as 3y in 4x + y = 13
4(3y) + y = 13
12y + y = 13
13y = 13
y = 1
Now, substitute 1 as y in x=3y
x = 3(1)
x = 3
Our solution is x = 3, y = 1. As a point, that is (3,1).
