Hello There!
The first thing we want to do is find the proportional relationship between to two triangles
The smaller triangles longest side is 18
Given the longest side of the similar triangle we can divide the longest side of the preimage by the longest side of the similar triangle
So the proportional relationship would be
36/18 or 2
Our next step is to find the the sides of the similar triangle
To do so we multiply the sides of the preimage by 2 (because 2 is the proportional relationship between the two triangles)
12x2=24
8x2=16
and we already know that the longest side measures 36
Now we can find the perimeter by adding all of the side lengths
36+24+16 = 76
So we can conclude that the perimeter of the dilated image is 76
Answer:
y = -0.85 + 0.09x; $49.82
Step-by-step explanation:
1. Calculate Σx, Σy, Σxy, and Σx²
The calculation is tedious but not difficult.
2. Calculate the coefficients in the regression equation
To two decimal places, the regression equation is
y = -0.85 + 0.09x
3. Prediction
If x = 563,
y = -0.85 + 0.09x = -0.85 + 0.09 × 563 = -0.85 + 50.67 = $49.82
(If we don't round the regression equation to two decimal places, the predicted value is $50.56.)
