Ответ:
Yes, the equation shifts down by five.
Step-by-step explanation:
In equations, vertical shifts happen when the ENTIRE equation, or y, is added or subtracted a number.
Horizontal shifts happen when JUST the x value is added or subtracted a number, but this is a little different.
The formula for the equation you gave us is
m(x - h) + k
Since "h" is already negative, we have to flip the sign of the +2, so the horizontal shift would be LEFT two units.
As far as the vertical shift goes, we just have to look at the "+k."
Since k = -5, the equation shifts down five units.
Ответ:
Yes, there s a vertical shift to the right by 1
Step-by-step explanation:
If you distribute the 2 among the (x+2) you get:
2x+4-5
Combine like terms:
2x+1
There fore the line shifts right by one.
Ответ:
x=height of the antenna
tan(66)=x/50
x=50*tan(66)
x=1.33 ft
->the height of the antenna = 1.33 ft
hope it is the correct answer because you didn't provided me enough information.
