Need Help On Question 13!! Urgent!!

Answers

Answer 1

Answer:

∠MNQ = 31

Step-by-step explanation:

Set ∠MNQ and ∠NQP equal to each other.

∠MNQ = ∠NQP

5c + 6 = 7c - 4

10 = 2c

c = 5

Then substitute back into ∠MNQ.

∠MNQ = 5c + 6

∠MNQ = 5(5) + 6

∠MNQ = 25 + 6

∠MNQ = 31

LMNP is rotated 180° clockwise around the origin.

Answers

Answer:

The correct answer is B

Step-by-step explanation:

-3,-4

Coordinates of M are (-3, -4) as LMNP rotates 180° clockwise.

What is clockwise rotation?

" Clockwise rotation means when any object is moving in the direction of hands of clock."

According to the question,

As per the diagram ,

Coordinates of M are ( 3, 4)

Rotation of a point through 180° about the origin when a point M( x, y) is rotated about the origin through 180° in anticlockwise or clockwise direction, it takes the new coordinates ( -x ,-y).

Therefore , coordinates of M are ( -3, -4).

Hence, coordinates of M are (-3, -4) as LMNP rotates 180° clockwise.

A car dealership buys a car for $12,500. They sell the car for $15,750. What is the percent markup?

Answers

Answer: 26%

Step-by-step explanation:

The formula to calculate the percentage markup is given as:

= Selling price - Cost / Cost price × 100

where selling price = $15750

Cost price = $12500

Percentage markup = ($15750 - $12500) / $12500 × 100

= $3250/$12500 × 100

= 26%

Answer: 26

Step-by-step explanation:

12,500 - 15,750= 3250

5. The table below represents a quadratic function: draw a graph plot points

What would be the axis of symmetry for the equation?
What is the vertex?
What are the roots?
What is the y-intercept?

Answers

Answer:

The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function.

Step-by-step explanation:

The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
