Answer:

A =28.26

Step-by-step explanation:

Using the area formula

A = pi r^2

We use pi = 3.14 and the radius is 3

A = 3.14 * (3)^2

A = 3.14 *9

A =28.26

Find a solution to the following system of equations. –5x + y = –5 –4x + 2y = 2

Arte-miy333 [17]

-5x + y = -5.....multiply by -2
-4x + 2y = 2
---------------
10x - 2y = 10 (result of multiplying by -2)
-4x + 2y = 2
-----------------add
6x = 12
x = 12/6
x = 2

-5x + y = -5
-5(2) + y = -5
-10 + y = -5
y = -5 + 10
y = 5

solution is (2,5)

A contemporary building has a window in the shape of a parallelogram with a base of 90 in and an adjacent side of 40 in. How man

BaLLatris [955]

260 inches of trim are needed to surround the window.

<h3 /><h3>What is the surface area?</h3>

The total land area of all the faces of a three-dimensional object is its surface area. When we wish to wrap something in real life, we employ the notion of surface areas of distinct things.

Actually, all we need is a trim that is the same size as our window and equal to the parallelogram's circumference, which is

The sum of the side is;

⇒Length of lower side + Length of the upper side

⇒ 90+90

⇒180 inches

The sum of adjacent sides;

Sum of adjacent sides = 40+40

Sum of adjacent sides = 80 inches

The length you should trim is needed to surround the window is found as;

⇒ 180 inches + 80 inches

⇒260 inches

Hence,260 inches of trim are needed to surround the window.

Answer:

zeros: x = 5, or (5, 0)

domain: x ≥ -4

Step-by-step explanation:

The zeros are the values of x where the graph crosses the x-axis. The graph crosses at x=5, so that is the zero.

___

The domain is the set of x-values for which the function is defined. There is no graph for x < -4, so the graph is only defined for x ≥ -4. The domain is x ≥ -4.

_____

The graph has the appearance of the graph of ...

$y=\sqrt{x+4}-3$
