Triangle B is the same shape as Triangle A with a scale factor of ſ. That means each side length is the side length of Triangle

goblinko [34]

Answer:

that description is already wrong. you must have mistyped something here. please read your own problem description again and then try again. if each side length of triangle B is the side length of triangle A, then they do not only share the same shape (= angles), but they are identical, and the scale factor is simply 1.

I think what you mean is that every side length of B correlates to the side lengths of A by the factor f.

Step-by-step explanation:

what that means :

side a of A = f × side a of B

side b of A = f x side b of B

side c of A = f x side c of B

perimeter of A = f x perimeter of B

for any more details there has to be more information.

Three terms of an arithmetic sequence are shown below. Which recursive formula defines the sequence?: f(1) = 6, f(4) = 12, f(7)

Gala2k [10]

A = 6
tn = a + (n - 1)d
t4 = 6 + 3d = 12
3d = 12 - 6 = 6
d = 6/3 = 2
f(n + 1) = f(n) + 2

Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly trav

ivann1987 [24]

Answer:

<h2>The dependent variable is distance, the equation is y = 20x, and the dragonfly will travel 480 miles.</h2>

Step-by-step explanation:

According to the graph, the dependent variable is Distance in miles, because it's on the vertical axis. Additionally, the independent variable is time in hours, because it's on the horizontal axis. However, you always put time as independent, because nothing affects time.

To find the equation, we just need to find the slope, using two points (0,0) and (2,40).

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{40-0}{2-0}=20$
