Answer:

To find the area of the rectangular sides, use the formula A = lw

To find the area of the triangular faces, use the formula A = 1/2bh,

Step-by-step explanation:

1st formula where A = area, l = length, and h = height.

2nd formula where A = area, b = base, and h = height.

To find the surface area of the triangular prisms, you need to use the following formula: A=2AB(a+b+c)h.

To find AB you use this formula:AB= square root of (s(s﹣a)(s﹣b)(s﹣c))

Substitute your values and you will be able to find your surface area.

Write an equation of a circle with a center at (2, - 4) and a radius of 4.

Answer:

(x -2)^2 +(y +4)^2 = 16

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is ...

(x -h)^2 +(y -k)^2 = r^2

You have (h, k) = (2, -4) and r = 4, so your equation is ...

(x -2)^2 +(y -(-4))^2 = 4^2

(x -2)^2 +(y +4)^2 = 16

What is the value of this expression when n approaches infinity?

topjm [15]

ANSWER

C. 35

EXPLANATION

The given expression is:

$15 - 35 - \frac{85}{n} + 55 + \frac{75}{2n} + \frac{15}{2 {n}^{2} }$

$n \to \: \infty$

$\frac{k}{n} \to0$

where k is a constant.

This implies that,

$15 - 35 - \frac{85}{n} + 55 + \frac{75}{2n} + \frac{15}{2 {n}^{2} } = 15 - 35 - 0 + 55 + 0+ 0 =35$

The correct answer is C

In a photograph, a house is 4 inches wide and 6 inches tall. The photograph is enlarged while keeping proportional dimensions, a

AlekseyPX

Since you keep proportional dimensions, the proportion between the old and new dimensions must be the same. So, if we call the new height $h$ , the preservation of the width/height ratio is written as

$4 \div 6 = 9 \div h$

Solving the proportion for $h$ yields

$h = \frac{6\cdot 9}{4} =\frac{3\cdot 9}{2} = \frac{27}{2} = 13.5$
