The quadratic function that models the graph on the image is given as follows:
y = (x - 1)² - 1.
What is the quadratic function?The features of the quadratic equation given from the graph are given as follows:
The vertex.The y-intercept.The equation of a quadratic function with vertex (h,k) is defined as follows:
y = a(x - h)² + k.
In which a is the leading coefficient of the function.
From the graph, the coordinates of the vertex are given as follows:
(1,1).
As the vertex is the turning point of the function.
Hence the parameters h and k have values of:
h = 1, k = 1.
Hence:
y = a(x - 1)² + 1.
The y-intercept of the function is of:
y = 2.
This means that when x = 0, y = 2, hence the leading coefficient a is obtained as follows:
2 = a(0 - 1)² + 1
a = 1.
Hence the equation is of:
y = (x - 1)² - 1.

A spinner with 10 equally sized slices has 4 yellow slices, 4 red slices, and 2 blue slice. Yolanda spun the dial 1000 times and got the following results. Answer the following. Round your answer to the nearest thousandth
Answers
Probability of landing on red 0.9%, when Yolanda spun the dial 1000 times.
What is probability?
The probability of an event can be calculated using the probability formula by simply dividing the favorable number of possibilities by the total number of outcomes. The likelihood of an event occurring can be anywhere between 0 and 1, as the favorable number of outcomes can never exceed the total number of outcomes.
A spinner with 10 equally sized slices has 4 yellow slices, 4 red slices, and 2 blue slices.
Yolanda spun the dial 1000 times.
P( getting red) = 19/1000
From the chart, there are 19 red out of 1000
Experimental probability of landing on red
= Number of red outcomes / Total number of spins
= 9/1000
Experimental probability of landing on red 0.009.

You have a carryover balance of $600 on a credit card that has a 18.99% annual percentage rate (APR). You have a recurring monthly purchase of $70 for your water bill and you make a payment of 7% of the ending balance is made each month. Complete the table below. Round each value to the nearest cent.
Answers
The completion of the credit card table is as follows:
Month Carryover Finance New Ending

1 $600 $10.60 $70 $680.60 $47.64
2 $632.96 $11.12 $70 $714.08 $49.99
How are credit card finance charges computed?Credit card attracts finance charges.
The finance charges are the interest for using some credit to finance purchases.
Most finance charges are based on the annual percentage rate (APR), which may also be used to obtain the monthly percentage rate (MPR) by dividing the APR by 12.
The finance charge is applied to the unpaid balance at the end of the period, which may be daily, weekly, or monthly.
Carryover balance = $600
Annual percentage rate (APR) = 18.99%
Monthly percentage rate (MPR) = 1.5825% (18.99% ÷ 12)
Recurring monthly purchase = $70
Monthly payment = 7% of the ending balance
The finance charge for month 1 = $10.60 ($600 + $70 x 1.5825%)
Payment for month 1 = $47.64 ($680.60 x 7%)
Carryover balance for month 1 = $632.96 ($680.60 - $47.64)
The finance charge for month 2 = $11.12 ($632.96 + $70 x 1.5825%)
Payment for month 2 = $47.64 ($714.08 x 7%)

If the point D (-6, 9) is reflected over the x-axis, the coordinates of D’ would be?
Answers
Answer:
D'(-6, -9)
Step-by-step explanation:
When a point is reflected over the x-axis, the x-coordinate remains the same. The reflected point is the same distance from the x-axis as the original point, but it's on the other side of the x-axis, so the y-coordinate changes sign.
In general, point (x, y) reflected over the x-axis becomes point (x, -y).
Here, point D(-6, 9) becomes point D'(-6, -9).

Answers
Answer:
1. The problem involves finding the length of a slide about a ladder. The slide and the ladder form a right triangle, with the ground and the slide as the hypotenuse.
2. The top of the ladder is 10 feet above the ground, and the bottom of the ladder is 12 feet from the bottom of the slide.
3. In order to solve this problem, a diagram can be used to represent the scenario.
4. Label the bottom of the slide as point A, the bottom of the ladder as point B, and the top of the ladder as point C.
5. Draw a straight line from point A to point B and label it 12 feet.
6. Draw a straight line from point B to point C and label it 10 feet.
7. Draw a straight line from point A to point C, which is the hypotenuse of the triangle.
8. Use the Pythagorean Theorem to find the length of the hypotenuse.
9. The Pythagorean Theorem states that a2 + b2 = c2, where a and b are the sides of the triangle and c is the hypotenuse.
10. In this problem, a is 12 feet, and b is 10 feet. Plugging these values into the equation, we get 122 + 102 = c2. Solving for c, we get that the length of the slide is 14.04 feet to the nearest tenth of a foot.

Answers
The converse, inverse, contrapositive and biconditional for the given sentences has been written down for a better understanding.
What are inverse statements?Two assertions that are logically opposed to one another are referred to be inverse statements. An inverted statement would be "It is raining" and "It is not raining."Biconditional statements can be both true and untrue depending on the veracity or falsity of each of its component elements. For instance, "If it is raining, then the ground is wet" is a biconditional statement because if it is raining, the ground will be wet, and if it is not raining, the ground won't be wet. In other words, the truth or falsehood of the first part (it is raining) determines the truth or falsehood of the second part.
How to solve?
Converse: If studying hurts your grade, then studying also helps your grade.
Inverse: If studying does not help your grade, then studying does not hurt your grade.
Contrapositive: If studying does not hurt your grade, then studying does not help your grade.
Bi-conditional: Studying helps your grade if and only if studying also hurts your grade.

The equation of the line in slope-intercept form that passes through (3, 4) and (4, 9) is: y = 5x - 11.
How to Find the Equation of a Line?The equation of a line can be written in point-slope form as y - b = m(x - a), if we know the slope (m) and a point (a, b) on the line. It can be rewritten to the slope-intercept form as y = mx + b.
Given the points on a line:
(3, 4) and (4, 9)
Slope of the line (m) = change in y / change in x = (9 - 4)/(4 - 3)
Slope of the line (m) = 5/1
m = 5
To write the equation of the line, substitute m = 5 and (a, b) = (3, 4) into y - b = m(x - a):
y - 4 = 5(x - 3)

A conditional statement is of the form "if..., then..."
For example, "If it rains, then the grass gets wet" is a conditional statement.
We can have a basic template of "If P, then Q" to represent any conditional. The P and Q are placeholders for logical statements.
The converse of that conditional is "If Q, then P". We swap P and Q.
