Answer:
X= 1984
Step-by-step explanation:
f(x) = 2000(X – 1980) + 10,000
Where,
f(x)= per capita income
x= year
Find x when f(x)= $18,000
f(x) = 2000(X – 1980) + 10,000
18,000 = 2000(X - 1980) + 10,000
18,000 = 2000X - 3,960,000 + 10,000
18,000 = 2000X - 3,950,000
Add 3,950,000 to both sides
18,000 + 3,950,000 = 2000X
3,968,000 = 2000X
Divide both sides by 2000
X= 3,968,000 / 2000
= 1984
X= 1984
Therefore, the per capita income was $18,000 in the year 1984

Step-by-step explanation:
The diagonal of a square is 10m long. What is the length of the side of the square?(Give your answer to the nearest cm)
Answer: 7 cm
Step-by-step explanation: The formula for this type of question is; √2×d÷2 where d stands for the diagonal so, √2×10÷2 = 7.071067812, to the nearest cm is 7cm.
Answer:
7 cm
Step-by-step explanation:
The diagonal divides the square into 2 right triangles.
Using Pythagoras' identity with the diagonal as the hypotenuse.
let x be the side of the square, then
x² + x² = 10²
2x² = 100 ( divide both sides by 2 )
x² = 50 ( take the square root of both sides )
x = [tex]\sqrt{50}[/tex] ≈ 7 cm ( to the nearest cm )

What are rational numbers?A number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer.
What are irrational numbers?Irrational number, any real number that cannot be expressed as the quotient of two integers.
How to find which expressions given equal a rational number?Firstly, we know that π is an irrational number .
So π x √4 = 2π
2π is an irrational number and so option A cannot represent a rational number.

PLEASE HELP ME!!. The local store where Tim shops charges 7% sales tax for clothing. Complete the table by figuring the cost of jeans after sales tax is applied. The first row has been done for you
Step-by-step explanation:
for 1 jeans
7% tax=7/100×25.68
=1.7976
So 1.7976$ is charged on one jeans.
7% tax for 2 jeans =2×1.7976
=3.5952$
Total price=3.5952+25.68
=29.2752
7% tax for 3 jeans=3×1.7976
=5.3928
Total price=5.3928+25.68
=31.0728
Hope this answer will help you
Answer:
$51.36
$77.04
Step-by-step explanation:
Multiply the cost of the number of pairs of jeans by the sales tax amount, 7%.
cost of 2 pairs: 48 + 7/100 x 48 = $51.36
cost of 3 pairs: 72 + 7/100 x 72 = $77.04

The solution to the inequality is x < 5/2.
What is an inequality?In Mathematics and Geometry, an inequality is a relation that compares two (2) or more numerical data, number, and variables in an algebraic equation based on any of the inequality symbols;
Greater than (>).Less than or equal to (≤).Less than (<).Greater than or equal to (≥).In this scenario and exercise, we would determine the solution set to the given inequality for x in parts as follows;
4x - 3 < 7
By adding 3 to both sides of the inequality, we have:
4x - 3 + 3 < 7 + 3
4x < 10
x < 10/4
x < 5/2.

Point O is on line segment NP. Given NP = 3x, NO = 2x, and OP = 8,
determine the numerical length of NO.
Answer:
[tex]NO = 16\ units[/tex]
Step-by-step explanation:
Given
[tex]NP = 3x[/tex]
[tex]NO = 2x[/tex]
[tex]OP = 8[/tex]
Required
Determine NO
Since O is a segment on NP, we have that
[tex]NP = NO + OP[/tex]
Substitute values for these parameters
[tex]3x = 2x + 8[/tex]
Collect Like Terms
[tex]3x - 2x = 8[/tex]
[tex]x = 8[/tex]
Substitute 8 for x in [tex]NO = 2x[/tex]
[tex]NO = 2 * 8[/tex]
[tex]NO = 16\ units[/tex]

Step-by-step explanation:
Consider the function f(x) = x2 – 331. Chivonne claims a domain restriction x ≥ 0 produces the inverse function f–1(x) = StartRoot x minus 331 EndRoot . Which statement describes whether Chivonne is correct? The expression for f–1(x) is correct, but the domain restriction is not. The domain restriction is correct, but the expression for f–1(x) is not. Both the expression for f–1(x) and the domain restriction are correct. Neither the domain restriction nor the expression for f–1(x) is correct.
Answer:
The correct option is;
The domain restriction is correct but the expression for f⁻¹(x) is not
Step-by-step explanation:
The expression for the function is given as follows;
f(x) = x² - 331
The inverse function suggested = f⁻¹(x) = √(x-331)
The domain restriction is x ≥ 0
The inverse function if given as follows;
y = x² - 331 (Interchange x and y to get)
x = y² - 331
x + 331 = y²
y = ±√(x + 331)
Given that the domain restriction has been put as x ≥ 0, we select the + case to give;
f⁻¹(x) = √(x + 331)
Therefore, the domain restriction is correct but the expression for f⁻¹(x) is not.
Answer: B
The domain restriction is correct, but the expression for f–1(x) is not.

Seventy-five (75) customers at Crummy Burger today were entered in a drawing. Three names will be drawn, and each will win a prize. Determine the number of ways that the prizes can be distributed if all 3 prizes are a $10 gift card.
Answer:
the number of ways in which the prizes are allocated is 67,525
Step-by-step explanation:
Given that
Number of customers = 75
Number of prizes = 3
And, the value of gift card = $10
Based on the above information,
The number of ways in which the prizes are allocated is shown below:
[tex]=^{75} C_3[/tex]
= [tex]\frac{75!}{(3!\times(75-3)!}[/tex]
After solving this the number of ways that came is 67,525
hence, the number of ways in which the prizes are allocated is 67,525
