Identify the figure shown and find its surface area. Explain how you found your answer.

photoshop1234 [79]

This is a triangle prism, the base is a square and the four sides are equal triangles.

To find the surface area you need to first find the areas of the triangles, then the square, in the end you have to add them together.

Since we know the area of a triangle is 1/2bh we know that one if the triangle in the figure is
9*16/2=72(in^2)
there are four of these so we multiply it by 4
4*72=288(in^2 aka squared inches)

Then we need to find the area of the square. side * side=9*9=81 (in^2)

Add them together we get the surface area.
288+81=369 (in^2)

In the year 2008, a company made $4.9 million in profit. For each consecutive year after that, their profit increased by 12%. Ho

laila [671]

Answer:

The profit of the company in 2011 is $ 6.89 million

Step-by-step explanation:

Given data

In 2008 profit made by the company (P) = $ 4.9 million

Increase in profit of the company R = 12 % yearly

Now the profit of the company in 2011 is given by

$P_{1} = P (1 + \frac{R}{100}) ^{T}$

Here P = $ 4.9 million

R = 12 % = 0.12

T = 3 years

Thus the profit of the company in 2011 is

$P_{1} = 4.9 (1 + \frac{12}{100}) ^{3}$

$P_{1}$ = 6.89 million dollars

Therefore the profit of the company in 2011 is $ 6.89 million

Select the conic section that represents the equation. y2 = 10x circle ellipse parabola hyperbola

Makovka662 [10]

The conic that represents the equation y² = 10x is a parabola

Step-by-step explanation:

The general equation for any conic section is

Ax² + Bxy + Cy² + Dx + Ey + F = 0, where A, B, C, D, E and F are

constants

1. If B² - 4AC < 0, if a conic exists, it will be either a circle or an ellipse,

if A and C are equal then it is a circle, if not then it is an ellipse

2. If B² - 4AC = 0, if a conic exists, it will be a parabola

3. If B² - 4AC > 0, if a conic exists, it will be a hyperbola

∵ The equation is y² = 10x

- Subtract 10x from both sides

∴ y² - 10x = 0

∴ A = 0 , B = 0 , C = 1 , D = -10 , E = 0 and F = 0

∵ B² - 4AC = (0)² - 4(0)(1) = 0

∴ B² - 4AC = 0

∴ The conic is parabola

The conic that represents the equation y² = 10x is a parabola
