What angle measure is complimentary to a 37 degree angle
Answer:
53 degree angle
Step-by-step explanation:
Two angles are said to be complementary if they add up to 90 degrees. Let the complementary angle of 37 degrees is x. These two angles must add up to 90 degrees. So we can set up the equation as:
37 + x = 90
Subtracting 37 from both sides, we get:
x = 90 - 37
x = 53 degree angle
From the above solution we can see that if we want to find the complementary angle of any angle, we can subtract the given measure from 90 degrees to get our answer.
Answer:53
Step-by-step explanation:
90-37=53
What is the pattern in the values as the exponents increase?
Answer:
"multiply the previous value by 3"
Step-by-step explanation:
We can easily see the pattern if we look at the 2nd, 3rd, 4th terms.
What makes 1 into 3? Of course, multiplying 1 by 3 gives us 3.What makes 3 into 9? Same, multiplying 3 by 3 gives us 9.Now, we can see 1st and 2nd terms (which wasn't that apparent for some). Does multiplying 1/3 by 3 give us 1? INDEED, it does!
So the rule is "multiplying the previous term by 3".

The amount Lin's sister earns at her part-time job is proportional to the number of hours she works. She earns $9.60 per hour. Is y a function of X. Write an equation describing x as a function of y
Using proportional relationships, it is found that:
y is a function of x, given by [tex]y = 9.6x[/tex].x as a function of y is given by [tex]x = \frac{9.6}{x}[/tex]What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
[tex]y = kx[/tex]
k is the constant of proportionality.
In this problem, considering:
x as the number of hours she works. y as her earnings.Lin's sister earns $9.60 per hour.Hence, y is a function of x, given by:
[tex]y = 9.6x[/tex]
Also, we can write x as a function of y, as follows:
[tex]x = \frac{y}{9.6}[/tex]
You can learn more about proportional relationships at https://brainly.com/question/25067191
Yes, y is a function of x as earnings are proportional to hours worked. The equation describing x as a function of y is x = y/9.60, since Lin's sister earns $9.60 per hour.
The problem states that the amount Lin's sister earns at her part-time job is proportional to the number of hours she works, and she earns $9.60 per hour. To answer the question whether y is a function of x, yes, y is indeed a function of x because for each value of x (number of hours worked), there is exactly one value of y (the earnings).
To write the equation describing x as a function of y, we start with the standard form of the equation for a direct proportion: y = kx, where k is the constant of proportionality. In this case, k is $9.60 per hour. So, the equation would normally be written as y = 9.60x. However, the question asks for x as a function of y. Therefore, we need to rearrange the equation to solve for x: x = y/9.60.

What is the perimeter of kite OBDE?
12 units
22 units
38 units
58 units
Answer:
38 units
Step-by-step explanation:
Triangle ABC is a right triangle. To find the missing side, AB (which is the hypotenuse), we use the Pythagorean theorem:
a²+b² = c²
10²+24² = c²
100+576 = c²
676 = c²
Take the square root of both sides:
√(676) = √(c²)
26 = c
AB is a diameter; this means the radius is 26/2 = 13. This means that OB = 13 and OE = 13.
BD and DE are congruent; this means that BD = 6.
This makes the perimeter
13+13+6+6 = 38 units.
The perimeter of kite OBDE is 38 units.
What is Pythagoras theorem?Pythagoras theorem states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
What is perimeter?Perimeter is the distance around the edge of a shape.
What is kite?A kite is a quadrilateral that has 2 pairs of equal-length sides and these sides are adjacent to each other.
According to the given question.
We have a circle with center o and diameter AB.
Triangle ABC is a right triangle.
To find the missing side, AB (which is the hypotenuse), we use the Pythagoras theorem.
So,
[tex](AB)^{2} = (10)^{2} +(24)^{2}[/tex]
[tex]\implies (AB)^{2} = 100+ 576\\\implies (AB)^{2} = 676\\\implies AB = \sqrt{676} \\\implies AB = 26[/tex]
Since, AB is the diameter of the circle. Therefore,
[tex]OB = \frac{AB}{2} \\\implies OB = \frac{26}{2} = 13[/tex]
Also, OBDE is a kite and we know that the adjacent sides of a kite are congruent.
[tex]\implies OB = BD = 13 \\\And,\ OE = ED = 6[/tex]
Therefore,
the perimeter of kite OBDE
= Length of sides (OB + BD + DE + EO )
= 13 + 13 + 6 + 6
= 26 + 12
= 38 units.
Hence, the perimeter of kite OBDE is 38 units.

Answer:
Hence choice A is correct
Step-by-step explanation:
Given equations are [tex]f(x)=\sqrt{x^2-1}[/tex] and [tex]g(x)=\sqrt{x-1}[/tex]
Now we need to find the value of [tex]\left(\frac{f}{g}\right)\left(x\right)[/tex]. Then select correct matching choice from the given choices.
Now let's find [tex](fof)(3)[/tex]
[tex]\left(\frac{f}{g}\right)\left(x\right)[/tex]
[tex]\left(\frac{f}{g}\right)\left(x\right)=\frac{f\left(x\right)}{g\left(x\right)}[/tex]
[tex]\left(\frac{f}{g}\right)\left(x\right)=\frac{\sqrt{x^2-1}}{\sqrt{x-1}}[/tex]
[tex]\left(\frac{f}{g}\right)\left(x\right)=\frac{\sqrt{\left(x+1\right)\left(x-1\right)}}{\sqrt{x-1}}[/tex]
[tex]\left(\frac{f}{g}\right)\left(x\right)=\sqrt{x+1}[/tex]
Hence choice A is correct
Answer:
a. (f/g)(x) = √x+1
Step-by-step explanation:
We have given two function.
f(x) = √x²-1
g(x) = √x-1
We have to find the quotient of f(x) and g(x).
(f/g)(x) = ?
The formula to find (f/g)(x) is :
(f/g)(x) = f(x) / g(x)
simplifying f(x) , we have
f(x) = √(x-1)(x+1)
f(x) = (√x-1)(√x+1)
Putting values in above formula, we have
(f/g)(x) = (√x-1)(√x+1) / √x-1
(f/g)(x) = √x+1 which is the answer.
the morgan famili and the alexander family each ised their sprinkles last summer. the water output was 20. l per hour. The water output rate for the Alexander family ‘s sprinkler was 40 L per hour. The families used their sprinklers for a combined total of 50 hours, resulting in total water output of 1400 L. How long was each sprinkler used?
Answer:
number of hours Alexander family ‘s sprinkler work = 20
number of hours Morgan family ‘s sprinkler work = 30
Step-by-step explanation:
Given in the question,
water output rate for the Alexander family ‘s sprinkler = 40 L
water output rate for the Morgan family ‘s sprinkler = 20 L
Suppose, number of hours Alexander family ‘s sprinkler work = x
Suppose, number of hours Morgan family ‘s sprinkler work = y
Equation1
x + y = 50
Equation 2
40x + 20y = 1400
x = 50 - y
Put this value of x in equation 2
40(50-y) + 20y = 1400
2000 - 40y + 20y = 1400
-20y = 1400 - 2000
-20y = -600
y = 30
Put this value of y in equation 1 to get the value of x
x + 30 = 50
x = 50 - 30
x = 20

Tracy needs to find the length and width of the equipment storage room where she works. The room is 2 meters longer than it is wide. Its perimeter is 16 meters.
What is the width in meters?
Answer:
3 meters
Step-by-step explanation:
We assume the storage room is a rectangle, like most rooms, no indication it is otherwise.
We know it's a rectangle and not a square because it is longer than wide.
We have the perimeter measurement (16 meters).
So, we can make the following equation:
2x + 2y = 16
x being the width of the room, y being it's length. A perimeter is the sum of all sides.
We also know the room is 2 meters longer than wide... so:
y = x + 2
If we replace y in the first equation by its value relative to x, we get:
2x + 2(x + 2) = 16 which becomes
2x + 2x + 4 = 16
4x =12
thus x = 3
Width: 3 meters
Length: 5 meters.
Confirms the 16 meters perimeter.
Answer:
Width = 3 meters
Step-by-step explanation:
We are given that for an equipment storage room, it is 2 meters longer than its width and the perimeter of this room is 16 meters.
Given the above information, we are to find the width of the room.
Perimeter = [tex]2l+2w[/tex]
Supposing [tex]x[/tex] to be the width and [tex]x+2[/tex] to the length, we can write it as:
[tex]16=2(x)+2(x+2)[/tex]
[tex]16=2x+2x+4[/tex]
[tex]12=4x[/tex]
[tex]x=\frac{12}{4}[/tex]
x = 3
Therefore, the width = 3 meters.
The graphs below have the same shape. What is the equation of the blue graph

- [tex]f(x-a)[/tex] shifts the function, [tex]f(x)[/tex], [tex]a[/tex] units to the right
We can infer from the picture that the blue graph is shifted 2 units to the right of the red graph, so we should apply the second rule:
[tex]f(x)=x^2[/tex]
[tex]g(x-2)=(x-2)^2[/tex]
[tex]g(x)=(x-2)^2[/tex]
We can conclude that the correct answer is C. [tex]g(x)=(x-2)^2[/tex]

Write 5 √ 4 using rational exponents.
To express 5 √ 4 using rational exponents, you write it as 5¹ × 4¹⁄₂, as the square root of a number is that number raised to the power of ½.
Explanation:To write 5 √ 4 using rational exponents, we must express the square root of 4 as a power. From our mathematical rules, we know that a square root can be written as an exponent of ½. Therefore, √4 is equivalent to 4 to the ½ power (4¹⁄₂).
Considering the expression 5 √ 4, we apply the same concept. The 5 is actually 5 to the power of 1 (5¹), and the square root of 4 is 4 to the ½ power. When these are multiplied together, we combine the base of 5 with the exponent expressions, remembering that the 4¹⁄₂ needs to be multiplied by 5¹. Consequently, 5 √ 4 becomes 5¹ × 4¹⁄₂.
The expression 5√4 can be written using rational exponents as 5 * [tex]4^{1/2}[/tex].
To express the given expression 5√4 using rational exponents, we start by understanding what the square root represents in exponential form. The square root of a number x can be written as [tex]x^{1/2}[/tex]. For our given expression, we need to follow these steps:
Rewrite the square root in exponential form. Since √4 is the same as [tex]4^{1/2}[/tex], we can replace √4 with [tex]4^{1/2}[/tex].Combine this with the provided factor of 5, giving us 5 *[tex]4^{1/2}[/tex].Therefore, the expression 5√4 can be written as 5 * [tex]4^{1/2}[/tex] using rational exponents.

What is the slope of a line with points at (-5,2) (4,-7)?
Answer:
-1
Step-by-step explanation:
To find the slope of a line, you would need to use the slope formula, and that is [tex]slope=\frac{y2-y1 }{x2-x1}[/tex]
This equation should be used every time you need to find a slope with two given points. If you remember this, you would find questions like this more easy.
First, you would need to plug in your coordinate points into the formula.
You would plug -7 in y2, 2 in y1. And then you will plug in 4 in x2, and -5 in x1.
Your equation should look like this:
[tex]\frac{-7-2}{4-(-5)}[/tex]
Then you solve.
For the top portion of your equation you would get -9. The -5 turns into a positive 5 because when you carry the negative over (distribute it), the negative cancels out and turns into a positive. When you add the 5 and the 4 together, it will get you 9. The bottom portion of the equation will be 9.
Your equation should now look like this:
[tex]\frac{-9}{9}[/tex]
Now, you divide.
When you divide, the two 9's end up as a whole, and you keep the negative since the negative doesn't cancel out in this situation. When you finish dividing, you would get -1.
Your FINAL answer would be -1.
Answer:
-1
Step-by-step explanation:
Slope formula:
↓
[tex]{\huge\frac{Y_2-Y_1}{X_2-X_1}[/tex]
[tex]\frac{(-7)-2}{4-(-5)}=\frac{-9}{9}=-1[/tex]
Therefore the slope is -1.
-1 is the correct answer.

a movie complex is showing the same movie in three theaters. In theater A, 112 of the 160 seats are filled. In theater B, 84 seats are filled and 56 seats are empty. In theater C, 63 of the 180 seats are empty. Which theater has the greater percent of its seats filled.
Answer: Theater A has the greatest percent of seats filled, at 70%
Step-by-step explanation:
To find out which theater has the greatest percent of its seats filled, we need to calculate the percentage of seats filled in each theater. We can use the following formula to calculate percentage:
Percentage = (Part / Whole) x 100
For theater A, we have 112 seats filled out of 160 total seats: Percentage for theater A = (112 / 160) x 100 = 70%
For theater B, we have 84 seats filled out of 140 total seats: Percentage for theater B = (84 / 140) x 100 = 60%
For theater C, we have 117 seats filled out of 180 total seats: Percentage for theater C = (63 / 180) x 100 = 35% (Note that we need to subtract 63 empty seats from the total seats to get the total filled seats in theater C)
Therefore, theater A has the greatest percent of its seats filled, at 70%.

To find the solutions of the quadratic equation given in the problem, you can apply the proccedure shown below:
- Subtract 40 from both sides of the equation.
- Multiply both sides of the equation by -1
- Apply square root to both sides of the equation.
Therefore, by applyin the steps above, you obtain:
[tex]40-x^2-40=0-40\\-x^2=-40\\(-1)(-x^2)=(-40)(-1)\\\\x^2=40\\\\\sqrt{x^2}=\±\sqrt{40}\\\\x=\±2\sqrt{10}[/tex]
Answer:
= ±2√10
Step-by-step explanation:
40 − x2 = 0
We could solve this by;
subtracting x² from both sides
we get;
40 = x²
Then we get the square root on both sides;
√x² = √40 ; but the square root of a positive number "a" is +√a or -√a
Therefore;
√x² = ± √40
x = ±√40
√40 = √4√10
= 2√10
Thus;
x = ±2√10
