Rectangle ABCD with coordinates A(1,1), B(4,1), C(4,2) and D(1,2) dilates with respect to the origin to give rectangle A’B’C’D’.
Delvig [45]

Answer: Option C.

Step-by-step explanation:

You need to find the distance AB with the formula for calculate the distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Then, substituting the coordinates of the points A(1,1) and B(4,1), you get:

AB=\sqrt{(4-1)^2+(1-1)^2}=3

You know that A'B'=6, then the scale factor of dilation can be calculated with:

k=\frac{A'B'}{AB}

Substituting values, you get:

k=\frac{6}{3}\\\\k=2

This matches with the option C.

Answer:

y - 3 = (1/2)(x - 4)

Step-by-step explanation:

The graph is hard to read, but we can make assumptions about the x- and y-values shown.  The y-intercept appears to be (0, 1) and the blue dot appears to be (4, 3).  Let's try finding the equation of the line using this assumed data:

The point-slope equation is y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.

We need the slope of the line.  Recall that m = rise/run.  Going from (0, 1) to (4, 3), x (the 'run') increases by 4 and y (the 'rise') increases by 2.  Thus, the slope is m = rise/run = 2/4, or 1/2.

Substituting the known values into the point-slope equation y - k = m(x - h), we get:

y - 3 = (1/2)(x - 4)

Solve the equation. 3g - 49 = 7
Alex777 [14]

Answer:

G= 56/3

Step-by-step explanation:

56/3 is an ugly number if you ask me but it was the answer I got, and here's how I got it!

So first off you want to change -49 to a positive and add it to 7! This will change the equation to 3g=56, from here just divide 56 by 3! Which if you don't turn into a fraction it'll just be a really long number. So g=56/3! If you have any more questions feel free to ask!

Tanzania [10]

Answer:

r = 8 cm

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

50.24 = 2 * (3.14) *r

50.24 = 6.28r

Divide each side by 6.28

50.24/6.28 = r

8 =r
