Answer:

$\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right]$

Step-by-step explanation:

Rotation 180° (in either direction) about the origin causes each coordinate to have its sign changed. Effectively, the coordinate matrix is multiplied by -1.

<em>Additional comment</em>

This is equivalent to reflection across the origin.

Answer:

The length of the long side is 147 ft

The length of the short side is 30 ft

Step-by-step explanation:

L=5s-3

s= 324-2L

324=2(5s-3)+s

distribute

324=10s-6+s

simplify

324=11s-6

add 6 to both sides

330=11s

divide by 11

30=s

Plug in the s value to determine the length of the long side

The length of a rectangle is x. The width of the rectangle is (x + 10). Write an expression for the area of the rectangle.

Fed [463]

Answer:

$A=x^2+10x$

Step-by-step explanation:

<u>Area of a Rectangle</u>

Given a rectangle of width W and length L, its area can be calculated with the formula:

A = WL

We are given the length of a rectangle is L=x and the width is W=x+10, thus the area is:

$A=x(x+10)$

Multiplying:

$\mathbf{A=x^2+10x}$

Drag each tile to the correct box. Not all tiles will be used.

Zina [86]

Answer:

$1,100 at 3.2% for 3 years -> $105.60

$990 at 3.15% for 4 years -> $124.74

$1,025 at 2.8% for 5 years -> $143.5

Step-by-step explanation:

Simple interest formula is:

A = P*(1 + r*t)

where A if final account, P is principal, r is annual interest rate (as decimal) and t is time in years

Interest earned is A - P, then:

I = P*(1 + r*t) - P = P(1 + r*t - 1) = P*r*t

If P = $1100, r = 0.032 and t = 3, then:

I = 1100*0.032*3 = $105.6

If P = $990, r = 0.0315 and t = 4, then:

I = 990*0.0315*4 = $124.74

If P = $1025, r = 0.028 and t = 5, then:

I = 1025*0.028*5 = $143.5
