Short Answer<br> 1. What is the domain and range for the parent function of g(x) = x+1?

konstantin123 [22]

Answer:

Domain= {XER} Range= {YER}

Step-by-step explanation:

This is a line equation. Lines continue infinitely in both the horizontal direction and vertical direction, so that means that the domain and range are both a set of all real numbers.

Claire is designing a banner that will hang in her classroom. The length of one diagonal of the banner is 48 inches, and the sid

zimovet [89]

Answer: No the banner is not square.

Step-by-step explanation:

If it were square, the diagonal would be about 35.36 inches.

Pythagorean Theorem: a² + b² + = c²

?25² + 25² = 48² ?

625 + 625 ?=? 2304

1250 ≠ 2304

√1250 ≈ 35.3553

The coordinate point F(-8, 0) after a dilation with scale factor of 0.25, centered at the origin, becomes the point

FrozenT [24]

Answer:

$(-2,\, 0)$ .

Step-by-step explanation:

Dilate a point $(x,\, y)$ by a scale factor of $r$ with $(a,\, b)$ as the center, and the resultant point would be at $(a + r\, (x - a),\, b + r\, (y - a))$ .

In this question:

Point to dilate: $(x,\, y) = (-8,\, 0)$ .

Scale factor: $r = 0.25$ .

Center of dilation: $(a,\, b) = (0,\, 0)$ .

The resultant point would be:

$(0 + 0.25\, (-8 - 0),\, 0 + 0.25\, (0 - 0))$ , which simplifies to $(-2,\, 0)$ .

Nathan wants to use coordinate geometry to prove that the opposite sides of a rectangle are congruent. He places parallelogram A

valentina_108 [34]

<h3><u>Answer:</u></h3>

The formula determine the distance from C to D is:

$\sqrt{(0-a)^2+(-b)^2}=\sqrt{a^2}=a$

<h3><u>Step-by-step explanation:</u></h3>

The formula that can be used to determine the distance from point C to point D is:

$\sqrt{(0-a)^2+(-b)^2}=\sqrt{a^2}=a$

We know that distance between two points A(a,b) and B(c,d) is equal to the length of the line segment AB and is calculated by the help of the formula:

$\sqrt{(c-a)^2+(b-d)^2}$

So, here we have:

(a,b)=(a,b) and (c,d)=(0,b)
