Let the height of the first tower be x, then the second tower is (160 - x) m taller than the first tower. Then
tan 30 = (160 - x)/80
160 - x = 80 tan 30
x = 160 - 80 tan 30 = 160 - 46.19 = 113.8 m
Therefore, the height of the first tower is 113.8 m.
The range are all the possible solutions for y. Since the domain is given, these are all the possible x values. To find the range, we can simply substitute each of these x values to the given function <span>f(x) = 3.2x.
</span>
<span>Given the domain, we use this to find the range values,
Domain: {-4, -2, 0, 2, 4}
</span>Range: {-12.8, -6.4, 0, 6.4, 12.8}
Hey there!
To start, the slope intercept equation format is y=mx+b where m=the slope and b=the y-intercept.
Because you appear to have a coordinate set to plug in for x and y as well as a slope of 4, you can plug your known values into the slope intercept equation:
y=mx+b
coordinate: (1,6)
y=6 (the y value of the coordinate point)
x=1 (the x value of the coordinate point)
m=4 (the slope of the equation, given)
6=4(1)+b
Because b, your y-intercept is your only missing value, you can simplify your equation and solve for b:
6=4(1)+b
6=4+b
b=2
Now that you have your two needed values, your slope and your y-intercept, your final equation should be y=4x+2, or the third choice.
Hope this helps and I hope you have a wonderful rest of your day! :)
