Answer:

1). Option C

2). Option A

Step-by-step explanation:

The given vertices of polygon ABCDE are A(2, 8), B(4, 12), C(10, 12), D(8, 8) and E(6, 6)

After reflection new polygon formed MNOPQ has the vertices M(-2, 8), N(-4, 12), O(-10, 12), P(-8, 8) and Q(-6, 6).

By comparing the vertices we find the x-coordinates of polygon ABCDE have been changed to MNOPQ by negative notation only.Y- coordinates are same.

Therefore, polygon ABCDE has been reflected across the y-axis.

Option C. is the answer.

If polygon MNOPQ is translated 3 units right and 5 units down then the new vertices of congruent polygon VWXYZ will be

M(-2, 8) = [(-2 - 3), (8 + 5)] = (-5, 13)

N(-4, 12) = [(-4 - 3), (12 + 5)] = (-7, 17)

O(-10, 12) = [(-10 - 3),(12 + 5)] = (-13, 17)

P(-8, 8) = [(-8 - 3), (8 + 5)] = (-11, 13)

Q(-6, 6) = [(-6 -3),(6 + 5)] = (-9, 11)

Therefore, Option A. is the correct option.

One more rectangular-shaped piece of metal siding needs to be cut to cover the exterior of a pole barn. The area of the piece is

xenn [34]

Answer:

Option A is correct

3.33 ft wide should the metal piece be.

Step-by-step explanation:

Area of rectangle(A) is given by:

$A =lw$ .....[1]

l is the length and w is the width of the rectangle respectively.

As per the statement:

One more rectangular-shaped piece of metal siding needs to be cut to cover the exterior of a pole barn. The area of the piece is 30 ft²

⇒A = 30 ft²

It is also given that the length is 1 less than 3 times the width

⇒ $l = 3w -1$ ft

Substitute the given values in [1] we have;

$30 = (3w-1) \cdot w$

Using distributive property: $a \cdot (b+c) = a\cdot b+ a\cdot c$

then;

$30 = 3w^2-w$

We can write this as:

$3w^2-w-30 = 0$

Factorize this equation:

Split the middle term we have;

$3w^2-10w+9w-30 = 0$

⇒ $w(3w-10)+3(3w-10=0)$

⇒ $(3w-10)(w+3)=0$

By zero product property we have;

$3w-10 = 0$ and w+3 = 0

Since, w cannot be negative;

so,

$w = \frac{10}{3} = 3.3333..$ ft

Therefore, to the nearest hundredth of a foot, 3.33 ft wide should the metal piece be.

Mila [183]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Sarah, Jose and you live in the same street:

Distance between you and Jose = 5 blocks

Distance between Jose and Sarah = 2 blocks

Distance (b) between you and Sarah:

Since it isn't stated whether Sarah lives closer to you than Jose or vice versa ;

Then;

Distance b between you and Sarah will be :

(Distance between you and Jose ± distance between Jose and Sarah)

b = (5 ± 2)

b = (5 + 2) or (5 - 2)

b = 7 blocks or 3 blocks
