The point D(2, -5) is rotated 90° counterclockwise around the origin. What are the coordinates of the resulting point, D′?

Answers

Answer 1

Answer:

D' = (5, 2)

Step-by-step explanation:

Try to join D and the origin using a line. Counterclockwise means in an opposite direction of rotation of the clock hands. So draw another line towards the right which is perpendicular to the previous line to fine the answer. Remember the length of the lines should be equal.

Answer:

D. right; scalene

Step-by-step explanation:

As you can see in the diagram you have a 90, 50, and 40 degrees angles. Because one of the angles is equal to 90 degrees (a right angle) this triangle can be classified as a right triangle.

No congruent sides are shown.... That means it's a scalene.

which point is 8 units away from ( 7, 5 ) ?

Answers

Answer:

C ( 7, -3 )

Step-by-step explanation:

Question:

which point is 8 units away from ( 7, 5 ) ?

Choices:

A : (0,-3 )B (15,13) C ( 7, -3 ) D ( 1, 5 )

Solution:

(7, 5) and (7, 3) have the same x-coordinate, 7.

They are both on a vertical line that passes through point (7, 0).

(7, 5) is 5 units above the x-axis.

(7, -3) is 3 units below the x-axis.

5 + 3 = 8

(7, 5) and (7, 3) are 8 units apart.

Answer: C ( 7, -3 )

Find the area of a triangle ABC when m is less than C = 14 degrees, a = 5.7 miles, and b = 9.3 miles.

Answers

Answer:

[tex]Area =6.41mi^2[/tex]

Step-by-step explanation:

Given

[tex]a = 5.7[/tex]

[tex]b = 9.3[/tex]

[tex]c = 14^\circ[/tex]

Required

The area of the triangle

This is calculated as:

[tex]Area =\frac{1}{2}* a * b * sin(c)[/tex]

So:

[tex]Area =\frac{1}{2}* 5.7 * 9.3 * sin(14)[/tex]

[tex]Area =\frac{1}{2}* 5.7 * 9.3 * 0.2419[/tex]

She calculated the equation of the trend line to be y = −3.5x + 20. Use this information to predict the number of times in one month Yolanda would visit a friend who is 4 miles from her home.

Answers

Answer:

y = −3.5x + 20 ; x = 4

y = -3.5(4) + 20

y = -14 + 20

In two or more complete senteces compare the number of x-intercepts in the graph of f(x)=x^2 to the number of x-intercepts in the graph of g(x)=x^2-7. Be sure to include the transformation that occured between the parent function f(x) and its image g(x)

Answers

Answer:

Step-by-step explanation:

f(x) = x² is an up-opening parabola with vertex (0,0). There is one x-intercept, and that is the vertex.

g(x) = x²-7 is the equivalent to f(x) shifted down 7 units. Since the vertex is below the x-axis and the parabola opens upwards, it intercepts the x-axis at two points.
