Answer:
B
Step-by-step explanation:
The graph of x² is known as the parent function. From it, all quadratics can be transformed to make their graphs. It can undergo a series of transformations like translations up/down/left/right or stretch and compression vertically and horizontally. Usually the equation can tell you you what transformations it undergoes. Since g(x) is the same equation as x² except for 4/5 this is a vertical compression. Since it is the leading coefficient under multiplication and 4/5 < 1, this is a compression vertically. Answer B is correct.
Your answer should be
16x^20 z^4
Answer:180
Step-by-step explanation:
So, you go to the y axis and find 40 meters on the graph. Then, you go across to find out that x (time in seconds) is 20 seconds. So, in 20 seconds Tom walks 40 meters.
First we need to assume that the sum of the angles is also 180°. if one is less than 90°, the other will be more. we can do this because in a plane 4-sided polygon the sum of the inner angles will always be 360°, and we already know the two angles on the right side
so we can say that:
3x + 20 + x = 180
Since we got only one variable in this equation, we can already solve for x.
4x + 20 = 180
4x = 160
x = 40
the lower left angle is just 40°
the upper left is three times that plus 20, so it's 160°
hope this helps you to get the method
