What is the area of the trapezoid shown? trapezoid A = ______ units²?

Answers

Answer:

74.1 units²

Step-by-step explanation:

Area of the trapezoid shown = ½×(AD + BC)×BE

Use distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex] to find AD, BC, and BE.

✍️Distance between A(-9, 4) and D(9, 1):

[tex] AD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(9 -(-9))^2 + (1 - 4)^2} [/tex]

[tex] = \sqrt{(18)^2 + (-3)^2} [/tex]

[tex] = \sqrt{(324 + 9} = \sqrt{333} [/tex]

[tex] AD = 18.2 units [/tex] (nearest tenth)

✍️Distance between B(-4, -3) and C(2, -4):

[tex] BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(2 -(-4))^2 + (-4 -(-3))^2} [/tex]

[tex] = \sqrt{(6)^2 + (-1)^2} [/tex]

[tex] = \sqrt{(36 + 1} = \sqrt{37} [/tex]

[tex] BC = 6.1 units [/tex] (nearest tenth)

✍️Distance between B(-4, -3) and E(-3, 3):

[tex] BE = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(-3 -(-4))^2 + (3 -(-3))^2} [/tex]

[tex] = \sqrt{(1)^2 + (6)^2} [/tex]

[tex] = \sqrt{(1 + 36} = \sqrt{37} [/tex]

[tex] BE = 6.1 units [/tex] (nearest tenth)

✔️Area of the trapezoid:

Area = ½×(AD + BC)×BE

Plug in the values into the formula

Area = ½×(18.2 + 6.1)×6.1

Area = ½×(24.3)×6.1

Area = 74.115 ≈ 74.1 units² (nearest tenth)

The two congruent sides will have congruent angles. One angle measurement is given. Triangle angles equal 180.

Take 180 and subtract the given angle 93.5. Then divide by 2 to get the measurements x and the other unknown.

180 - 93.5 = 86.5

Each line represents a proportional relationship. Write an equation for each line. Show your work.

Answers

Answer:

The equation of line a is y = x

The equation of line b is y =  [tex]\frac{2}{3}[/tex] x

Step-by-step explanation:

The equation of the proportional is y = m x, where

m is the slope of the line (constant of proportionality)

The rule of the slope of a line is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where

(x1, y1) and (x2, y2) are two points on the line

Line a passes through points (0, 0) and (3, 3)

x1 = 0 and y1 = 0

x2 = 3 and y2 = 3

→ Substitute them in the rule of the slope above

∵ m = [tex]\frac{3-0}{3-0}=\frac{3}{3}[/tex]

m = 1

→ Substitute in the form of the equation above

∴ y = (1)x

y = x

The equation of line a is y = x

Line b passes through points (0, 0) and (3, 2)

x1 = 0 and y1 = 0

x2 = 3 and y2 = 2

→ Substitute them in the rule of the slope above

∵ m = [tex]\frac{2-0}{3-0}=\frac{2}{3}[/tex]

m = [tex]\frac{2}{3}[/tex]

→ Substitute in the form of the equation above

∴ y = ([tex]\frac{2}{3}[/tex]) x

y =  [tex]\frac{2}{3}[/tex] x

The equation of line b is y =  [tex]\frac{2}{3}[/tex] x

Write the coordinates of the point C after dilation with scale factor of 5, centered at the orgin

Answers

Answer:

Coordinates of point C after dilation with a scale factor of 5, centered at the origin will be: C'(10, 5)

Step-by-step explanation:

Given the point C

C(2, 1)

A dilation with a scale factor of 5 means the size of the coordinates of the image of point P will be 5 times larger than than the original coordinates of point C.

Thus, the rule of dilation by a scale factor 5 is:

(x, y)  →  (5x, 5y)

C(2, 1)  →  (5x, 5y) = (5(2), 5(1)) = C'(10, 5)

Therefore, coordinates of the point C after dilation with a scale factor of 5, centered at the origin will be: C'(10, 5)

A circles circumference is approximately 76cm. Estimate the radius, diameter and area of the circle.

Answers

Answer:

The circumference of a circle is C = 2πr^2 (2nd power) Radius (r) is the distance from the center of the circle to the outside of it. To find radius divide the diameter (d) by 2. The diameter (d) of a circle is the radius (r) multiplied by 2. To find the diameter (d) you need to do C ÷ π.

For example):

Finding diameter - 76/3.14 = 24.19 (d)

Finding radius - 24.19/2 = 12.095 (r)

Answers

Answer:

She can determine that while there is an association between the variables, there is no correlation, and she cannot determine causation.

Step-by-step explanation:

Since there is an arch shape to her graph, we know that as one variable changes, the other changes in the same manner. This means there is an association between the variables.

However, since the graph is not linear, there is no correlation between the variables. Since there is no correlation, we cannot determine causation.

Mark me as brainiest

Answer:

Sample response

Step-by-step explanation:

Because the graph shows a pattern that is an arch shape, Hope can conclude that there is an association between the variables. However, because the relationship is not linear, there is no correlation. The pattern shows that as one variable changes, the other variable changes in the same way. This does not imply that a change in one variable causes the change in the other variable to happen. Hope cannot conclude that there is a causal relationship.
