A triangular pyramid and its net are shown. Rain uses the calculations below to conclude that the surface area of the triangular pyramid is 238.5 square inches. 3 x 10 x 13) + ( x 10 x 8.7) 3 (65) + 43.5 238.5 Is Rain correct? Use the drop-down menus to explain your reasoning.

Answers

Answer 1

Answer:

Yes, Rain is correct

238.5 square inches

Step-by-step explanation:

Surface Area of a Triangular Pyramid,A = 1/2(a × b) + 3(1/2 × b × s)

= (1/2 × 10 × 8.7) + 3(1/2 × 10 × 13)

= 43.5 + 3(65)

= 43.5 + 195

= 238.5 square inches

The surface area of the triangular pyramid = 238.5 square inches

Answer 2

The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

From the net attached:

Surface area = 3(1/2 * 10 * 12) + (1/2 * 10 * 8.7)

Surface area = 223.5 in²

The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.

Answers

Answer:

-2.5

Step-by-step explanation:

5b - b - 1 ≥ -11

4b - 1 ≥ -11

+1 +1

4b ≥ -10

4/4 -10/4

b ≥ -2.5

Answer:

b ≥ [tex]-\frac{5}{2}[/tex]

Step-by-step explanation:

The expression:

5b - b - 1 ≥ -11

Now to solve this problem, we must be aware of some rules of inequality.

When dividing or multiplying with a negative value, the sign of the inequality must change;

5b - b - 1 ≥ -11

4b - 1 ≥ -11

Add + 1 to both sides;

4b -1 + 1 ≥ -11 + 1

4b ≥ -10

Now divided both sides by 4;

[tex]\frac{4b}{4}[/tex] ≥ [tex]\frac{-10}{4}[/tex]

b ≥ [tex]-\frac{5}{2}[/tex]

Given that x = 3 + i is a solution of the equatio
f(x) = 0, solve f(x) = 0 completely.

Answers

Answer:

x = 0, 2, 5/2 ± 1/2i

Step-by-step explanation:

I'm not really sure what the question is asking but I'm going to assume you want to find the zeroes of the function.

0 = 2x^4 - 14x^3 + 33x^2 - 26x

~Factor

0 = x(x - 2)(2x² - 10x + 13)

~Set factors to equal 0 and solve

x - 2 = 0

x = 2

2x² - 10x + 13 = 0

~Use quadratic formula

x = 0, 5/2 ± 1/2i

The volume of the figure is 126 cubic cm

Step-by-step explanation:

The figure consists of two rectangular prisms of dimensions 6 x 7 x 1 and 3 x7 x 4 respectively.

Calculate the first volume:

[tex]V_1=6~cm\cdot 7~cm\cdot 1~cm= 42~cm^3[/tex]

[tex]V_1= 42~cm^3[/tex]

Calculate the second volume:

[tex]V_2=3~cm\cdot 7~cm\cdot 4~cm= 84~cm^3[/tex]

[tex]V_2= 84~cm^3[/tex]

The total volume of the figure is the sum of both volumes:

[tex]V_t=V_1+V_2=42~cm^3+84~cm^3=126~cm^3[/tex]

The volume of the figure is 126 cubic cm

Write equations for the horizontal and vertical lines passing through the point (4, -5).
horizontal line: 0
OO
Х
vertical line:

Answers

Answer:

Horizontal line: y=-5

Vertical line: x = 4

Step-by-step explanation:

As we have to determine the equations for the horizontal and vertical lines passing through the point (4, -5).

To determine the equation for the horizontal line passing through the point (4, -5), we must observe that the horizontal line will always have the same y-value regardless of the x-value.

Therefore, the equation of the horizontal line passing through the point (4, -5) will be: y=-5

To determine the equation for the vertical line passing through the point (4, -5), we must observe that the vertical line will always have the same x-value regardless of the y-value.

Therefore, the equation of the vertical line passing through the point (4, -5) will be: x=4

Hence:

Horizontal line: y=-5

Vertical line: x = 4

CD and EF are parrellel to AB.They divide the area of triangle PAB into three equal parts. If PE=1, what is AC?

Answers

Answer:

AC is approximately 0.3178

Step-by-step explanation:

The given parameters are;

In ΔPAB

CD ║ EF ║ AB

The area of triangle ΔPEF = 1/3 × area of triangle ΔPAB

Therefore, PE = 1/√3·PA

PA = √3

We have area of ΔPCD = 2/3 × area of triangle ΔPAB

∴ PC = √(2/3) × PA = √(2/3) × √3

PC = √2

Therefore, AC = PA - PC = √3 - √2

AC = √3 - √2 ≈ 0.3178

Answer:

A Δ DOC = 6 in²

Step-by-step explanation:

Look at the attached graph

∵ ABCD is a trapezoid with legs AB and CD

∴ AD // BC

In Δs ABC and DCB

∵ BC is a common base

→ The heights of the Δs drawn from the points A and D to the base

BC are equal because the line joining A and D, AD is parallel to

the base BC

∴ Their heights are equal

→ Triangles of the same base and equal heights are equal in areas

∴ A Δ ABC = A Δ DCB

∵ A Δ ABC = A Δ ABO + A Δ BOC

∵ A Δ DCB = A Δ DOC + A Δ COB

→ Equate their right sides

∴ A Δ ABO + A Δ BOC = A Δ DOC + A Δ COB

∵ A Δ BOC = A Δ COB ⇒ common triangle

∴ A Δ ABO = A Δ DOC

∵ A Δ ABO = 6 in²

∴ A Δ DOC = 6 in²
