Answers
Answer:
The sets of ordered pair which are functions are;
III. {(3, 0.3), (-3, 0.3)} and IV. {(-2, 2), (2, -2)}
Step-by-step explanation:
The given ordered pairs are;
I. {(2, 3), (2, 4)}, III. {(3, 0.3), (-3, 0.3)} IV. {(-2, 2), (2, -2)}
A combination of ordered pair represent a function if each input is associated with only one output
Therefore, we have;
For I, the single input value, 2 maps to two output values, 3 and 4, therefore, the set of ordered pair {(2, 3), (2, 4)} does not describe a function
For II, the input values, 3 and -3 maps to the single output value, 0.3, therefore, each input has only one output and the set of ordered pair {(3, 0.3), (-3, 0.3)} describes a function
For IV, the input values, -2 and 2 maps to the output values, 2, and -2 therefore, each input has only one output and the set of ordered pair {(-2, 2), (2, -2)} describes a function

Describe Right Angled Triangle?A right-angled triangle is a triangle that has one angle measuring 90 degrees, which is known as the right angle. The sides adjacent to the right angle are known as the legs of the triangle, while the side opposite the right angle is known as the hypotenuse.
The Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs, is one of the fundamental theorems of mathematics and is used extensively in various fields.
Let's call the width of the shelf "x". According to the given diagram, we have a right triangle where the base is x, the perpendicular is 10 inches, and the angle between the hypotenuse and the perpendicular is 45 degrees.
Using trigonometric ratios, we know that:
tan(45) = perpendicular/hypotenuse
tan(45) = 10/x
Since tan(45) is equal to 1, we can simplify the equation to:
1 = 10/x
Solving for x, we get:
x = 10
Therefore, the width of the shelf is 10 inches.

Ann is a professional photographer. She has a photo 8cm long and 6cm wide. A customer wants a print of the photo. The print is to be similar to the original, but have half the area of the original. Ann plans to reduce the length and width of the photo by the same amount. What are the dimensions of the print? (Show work)
Answers
Answer: 6 cm by 4 cm
Step-by-step explanation:
Half of 48 = 24
(8-x)(6-x) = 24
x^2 - 14x + 24 = 0
FACTOR THE PROBLEM
x(x-2) -12(x-2) = 0
Therefore, x either equals 2 or 12
We reject 12 because it is larger than both of the original dimensions
CHECK
(8-2)(6-2) = 24

PLEASE HELP ASAP Jodi borrowed money from her aunt and agreed to pay her 5% simple annual interest. At the end of 3 years, she owes $30 in interest. How much did Jodi originally borrow?
Answers
Joni pays an annual interest of 5%, which means that in three years, the interest is 15%.
Let us assume that the amount Joni borrowed is m.
After three years, the interest is $30.
15% of the amount m = $30
0.15m = 30
m = 30/0.15 = 200
Therefore, Jodi originally borrowed $200.
