The domain of the composite functions:
a). (f + g)(-2) = 23
b). (f - g) (-2) = 1
c). f(x) - g(x) = x² - 5x - 13
What is composite function?A function is composite when the co- domain of the first mapping is the domain of the second mapping
Given the functions f(x) = x² - 4x and g(x) = x + 13, we shall evaluate the domains of the functions as follows:
a). (f + g)(-2) = (-2)² - 4(-2) + (-2) + 13
(f + g)(-2) = 4 + 8 - 2 + 13
(f + g)(-2) = 23
b). (f - g) (-2) = (-2)² - 4(-2) - (-2) - 13
(f - g)(-2) = 4 + 8 + 2 - 13
(f - g) (-2) = 1
c). f(x) - g(x) = x² - 4x - x - 13
f(x) - g(x) = x² - 5x - 13
Therefore, the domain of the composite functions:
a). (f + g)(-2) = 23
b). (f - g) (-2) = 1
c). f(x) - g(x) = x² - 5x - 13

Agatha borrowed $4,500 from the bank. 4 years later, Agatha owes the bank $5,040. What was the percentage rate of simple interest in the loan?
Answer:
12%
Step-by-step explanation:
If we subtract both numbers we get 540.
\(\frac{540}{4500} = \frac{x}{100} \\\)
540 x 100 = 54,000
54,000 / 4,500 = 12%
Find the area of a trapezoid with bases of 16 feet and 10 feet and a height of 3 feet. 39 ft2 78 ft2 240 ft2 480 ft2
Answer: 39 ft2
Step-by-step explanation:
The area of the trapezoid is 39 square feet.
To find the area of a trapezoid, you can use the formula:
Area = (1/2) × (base1 + base2) × height
Given that the bases of the trapezoid are 16 feet and 10 feet, and the height is 3 feet, we can substitute these values into the formula:
Area = (1/2) × (16 + 10) × 3
Area = (1/2) × 26 × 3
Area = (1/2) × 78
Area = 39 ft^2
Therefore, the area of the trapezoid is 39 square feet.

If a giant microwave is 9 feet long, 6 feet wide, and 3 feet high, what is its volume in cubic yards?
Answer:
322
Step-by-step explanation:
The volume of the giant microwave is 6 cubic yards.
What is a cube?It is a polygon having six faces.
The volume of a cube is side³.
We have,
Length = 9 feet
Width = 6 feet
Height = 3 feet
The volume of the giant microwave.
= 9 x 6 x 3
= 162 cubic feet.
1 yard = 3 feet
Cube on both sides.
1 yard³ = 27 feet³
Multiply 162/27 on both sides.
162/27 yard³ = 162 feet³
6 yard³ = 162 feet³
Thus,
6 cubic yards is the volume of the giant microwave.

Step-by-step explanation:
In a triangle,
The midsegment is the segment which joining the midpoints of two opposite sides of itThe length of the midsegment is half the length of the third side in the triangle which opposite to itLet us use this rule to solve our question
In Δ AC
∵ DE is the midsegment of it
∵ DE is opposite to the side AC
∴ The length of DE = 1/2 the length of AC
∵ The length of AC = 18
∴ The length of DE = 1/2 × 18
∴ The length of DE = 9
∴ The length of the midsegment is 9

Using the circles:

A = πr² = π(8²) ≈ 201.06 square inches
C = 2πr = 2π(8) ≈ 50.27 inches
Rounding to the nearest hundredth:
A ≈ 201.06 square inches
C ≈ 50.27 inches
Therefore, the area is approximately 201.06 square inches and the circumference is approximately 50.27 inches.
A circle with a diameter of 20 meters has a radius of 10 meters. The area and circumference are given by:
A = πr² = π(10²) ≈ 314.16 square meters
C = 2πr = 2π(10) ≈ 62.83 meters
Rounding to the nearest hundredth:
A ≈ 314.16 square meters
C ≈ 62.83 meters
Therefore, the area is approximately 314.16 square meters and the circumference is approximately 62.83 meters.
Using these relationships, find the measures of some of the angles:
a) mJKP = mJKN (by vertical angles) and mJKP + mPKL = 90° (by complementary angles), so mJKN + mPKL = 90°.
b) mJKN = mJKP (by vertical angles) and mJKN + mKNM = 90° (by complementary angles), so mJKP + mKNM = 90°.
c) mJLK = mMPL (by alternate interior angles) and mMPL = 63°, so mJLK = 63°.
d) mKNM = 90° - mJKN (by complementary angles). We cannot determine the measure of mJKN.
e) mJLK = mMPL (by alternate interior angles) and mJLR = mJLP (by vertical angles), so:
mJLK + mKLP + mPLJ + mJLP = 360° (by the sum of angles in a quadrilateral)
63° + 90° + mPLJ + mJLP = 360°
mPLJ + mJLP = 207°
f) mJLR = mJLP (by vertical angles) and mKPL = 90°, so:
mJLR + mJLP + mKPL = 180° (by the angles in a triangle)
mJLR + mJLP + 90° = 180°

Jeff is making cookies for his school. He needs 150 cookies. One recipe makes 60 cookies and uses 1.5 cups of butter. How many tablespoons of butter will be needed to make 150 cookies? (1 cup = 16 Tbsp.) Show how to use unit fractions to solve this problem.
Answer
Since one recipe makes 60 cookies, we can write the unit fraction LaTeX: \frac{1\text{ recipe}}{60\text{ cookies}}1 recipe 60 cookies. Since one recipe uses 1.5 cups of butter, we can write the unit fraction LaTeX: \frac{1.5\text{ cups butter}}{1\text{ recipe}}1.5 cups butter 1 recipe. And since 1 cup = 16 Tbsp., we can write the unit fraction LaTeX: \frac{16\text{ Tbsp}}{1\text{ cup}}16 Tbsp 1 cup.
Multiply:
LaTeX: \frac{150\text{ cookies}}{1} \cdot \frac{1\text{ recipe}}{60\text{ cookies}} \cdot \frac{1.5\text{ cups butter}}{1\text{ recipe}} \cdot \frac{16\text{ Tbsp}}{1\text{ cup}}150 cookies 1 ⋅ 1 recipe 60 cookies ⋅ 1.5 cups butter 1 recipe ⋅ 16 Tbsp 1 cup
= LaTeX: \frac{150(1)(1.5)(16)}{1(60)(1)(1)} 150 ( 1 ) ( 1.5 ) ( 16 ) 1 ( 60 ) ( 1 ) ( 1 )
= 60 Tbsp. butter
To make 150 cookies 60 tablespoons of butter is needed.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
From the given information we can solve this problem by using the proportional method.
Assuming 'x' cups of butter is needed to make 150 cookies.
Therefore,
60 : 1.5 : : 150 : x.
60/1.5 = 150/x.
60x = 225.
x = 225/60.
x = 3.75 cups.
Also given that 1 cup is equal to 16 tablespoons.
Therefore, 3.75 cups is equal to (3.75×16) tablespoons.
= 60 tablespoons.

Answer: The manager should sell the chair for $1740.
Step-by-step explanation:
45% of 1200 Solve this to find the amount increase
0.45 * 1200 = 540 Now add this amount to find the price.
$1200 + $540 = $1740

Use a technique of integration or a substitution to find an explicit solution of the given differential equation. dy/dx = sin(root(x))/root(y)
Finding an explicit solution for the differential equation \(dy/dx = sin(\sqrt x)/\sqrt y\) is not possible using standard techniques of integration or substitution.
A separable differential equation is one in which the variables x and y can be separated, meaning that the equation can be written in the form f(x) dx = g(y) dy. This type of equation can be easily solved by integrating both sides and finding the constant of integration. However, in the equation dy/dx = sin(√x)/√y, the sin function makes it a nonlinear differential equation, meaning that it cannot be separated into a product of two functions, one of x and one of y.
This type of differential equation cannot be solved using standard methods and requires more advanced techniques, such as numerical methods or perturbation methods. Numerical methods, such as Runge-Kutta or finite differences, involve approximating the solution at discrete points and then using interpolation to find the solution over a continuous interval. Perturbation methods involve making a series expansion of the solution and finding the coefficients of the series recursively.

Step-by-step explanation:
Given
\(\sqrt{x-6}\) + 5 = 12 ( subtract 5 from both sides )
\(\sqrt{x-6}\) = 7 ( square both sides )
x - 6 = 49 ( add 6 to both sides )
x = 55
Answer:
B. Subtract 5 from both sides and then square both sides.
Step-by-step explanation:
First, subtract 5 from both sides in order to get \(\sqrt{x-6}=7^{2}\)
Second, square both sides in order to get \(x-6=49\) (p.s. squaring both sides gets rid of the square root)
Third, add 6 to both sides in order to get x=55
Last, see that the answer is B, as you had to subtract 5 from both sides and then square both sides to get your answer

What is m angle H + m angle J?
Answer:
180°
Step-by-step explanation:
The measure of an inscribed angle (inscribed inside a circle) is half the measure of its inscribed arc.
m∡H = (1/2)(m arc GJI)
m∡J = (1/2)(m arc GHI)
m∡H + m∡J = (1/2)(m arc GJI + m arc GHI)
But those two arcs added together on the right side are the whole circle, so they add to 360°.
m∡H + m∡J = (1/2)360°
m∡H + m∡J = 180°
