Answer:
The option D) is correct "2 x squared minus 2; domain: all real numbers "That is [tex](f-g)(x)=2x^2-2[/tex] and domain is all real numbersStep-by-step explanation:
Given that the functions f and g are defined by
[tex]f(x)=2x^2+x-3[/tex] and [tex]g(x)=x-1[/tex]
To perform the indicated operation (f-g)(x) and then find the domain :To find (f-g)(x)
(f-g)(x)=f(x)-g(x)Substitute the values of the functions we get
[tex](f-g)(x)=f(x)-g(x)=2x^2+x-3-(x-1)[/tex]
[tex]=2x^2+x-3-1(x)-1(-1)[/tex]
[tex]=2x^2+x-3-x+1[/tex]
[tex]=2x^2-2[/tex] ( by adding the like terms )
Therefore [tex](f-g)(x)=2x^2-2[/tex] and domain is all real numbersThe option D) is correct "2 x squared minus 2; domain: all real numbers "The value of (f-g)(x) is [tex]2x^2-2[/tex]. Thus, the correct option is (D)
Two different functions are given that are as follow:
[tex]f(x)=2x^2+x-3[/tex]
[tex]g(x)=x-1[/tex]
We need to determine the value of the composite function that is (f-g)(x).
Now, by using the property of the composite function (f-g)(x) can also be written as:
[tex](f-g)(x)=f(x)-g(x)[/tex]
Substitute the values of both the functions and solve it further for (f-g)(x).
[tex]\begin{aligned}(f-g)(x)&=(2x^2+x-3)-(x-1)\\&=2x^2+x-3-x+1\\&=2x^2-2\\&=2(x^2-1)\end{aligned}[/tex]
Thus, the value of (f-g)(x) is [tex]2x^2-2[/tex]. Thus, the correct option is (D)

The cost of the car is $31824
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: Price of the car =$24,800 down payment % =18 and monthly installment of $760
Thus Total cost= $24,80×0.18+36×760
= $31824
Hence, The cost of the car is $31824

Answer:
Both [tex]x<-36\quad \mathrm{or}\quad \:x>72[/tex] are the True solutions.
Step-by-step explanation:

Please I need answers as soon
Answer: 0.00108154877
Step-by-step explanation:
The division [tex]\frac{5}{4623}[/tex] results in the simple decimal 0.001081603. This expression is already reduced to the most basic fraction form of itself.
The division is an arithmetic operation that involves splitting a quantity or number into equal parts or groups. It is the inverse operation of multiplication. In division, a number called the dividend is divided by another number called the divisor to obtain the quotient.
The dividend is the total quantity or number being divided, while the divisor is the number by which the dividend is divided. The result of the division is called the quotient, which represents the number of times the divisor can be subtracted from the dividend to achieve equal parts.
Given the expression [tex]\frac{5}{4623}[/tex] ,

Thus the given expression is factored
Final answer:
The expression x²−12x+36 is factored as (x-6)(x-6) or (x-6)².
Explanation:
The expression x²−12x+36 represents a quadratic equation. To factor this expression, we look for two numbers that both add to the middle term, -12, and multiply to the constant term, 36. The numbers that fit this requirement are -6 and -6, since (-6) + (-6) = -12 and (-6) × (-6) = 36. Therefore, the expression in factored form is (x-6)(x-6), which can also be written as (x-6)².

Answer:
87.92 in²
Step-by-step explanation:
pi × (R² - r²) = area
Where R is the radius of the outer circle and r of the inner circle.
Since C = 2pi×r
37.68 = 2×3.14×r
r = 6 in
R = 6 + 2 = 8 in
Therefore,
pi × (R² - r²) = area
Area = 3.14 (8² - 6²)

A. 22°
B. 68°
C. 90°
D. 112
In the context of geometry, vertical angles are always congruent, which means they have the same measure. If one of the vertical angles measures 68°, the measure of the other angle is also 68°. Therefore, the correct answer is B. 68°.
Explanation:The question is asking for the measure of the second angle, given that two angles are vertical angles and one of them measures 68°. In terms of geometry, vertical angles are the angles that are opposite each other when two lines intersect. An important property of vertical angles is that they are always congruent, which means they have the same measure. So, if one of the vertical angles is 68°, the other angle is also 68°.

A square has a perimeter of 32 inches what the length and width of the square
The length and width of square is 8 inches.
Step-by-step explanation:
Given,
Perimeter of square = 32 inches
We know that all sides of square are equal, therefore,
Length = width = s
Perimeter of square = 4s
[tex]32=4s\\4s=32[/tex]
Dividing both sides by 4
[tex]\frac{4s}{4}=\frac{32}{4}\\s=8[/tex]
Therefore,
The length and width of square is 8 inches.
Final answer:
The length and width of the square are each 8 inches, calculated by dividing the given perimeter of 32 inches by the number of sides of a square, which is 4.
Explanation:
To find the length and width of a square given its perimeter, we need to recall that all four sides of a square are of equal length. Since the perimeter of the square is 32 inches, we divide this number by 4 to find the length of one side. So, the length and width of the square are:
32 inches ÷ 4 = 8 inches.
Therefore, each side of the square is 8 inches long.

a. 5^7 x 5^-4

e. 5^3 - 5^0
Expressions a, b, and d are equivalent to 5^3. They all follow the laws of exponents, resulting in the same value of 5^3, or 125.
Explanation:The question is asking which expressions are equivalent to 5^3. Let's break down each option:
a. 5^7 x 5^-4: Utilizing the law of exponents, we add the exponents when multiplying the same base, hence we get 5^3. b. 5^12/5^9: According to the law of exponents, we subtract the exponent of the denominator from the exponent of the numerator, which gives us 5^3. c. 5^1 + 5^2: This equals 5 + 25, which is not equal to 5^3 (125). d. 5^0 x 5^3: Any number raised to the power 0 is 1, therefore this equals 5^3. e. 5^3 - 5^0: This equals 125 – 1, which is not equal to 5^3 (125).
So, options a, b, and d are equivalent to 5^3.
