Answer:
y=x-3/15
Step-by-step explanation:
f(x)=15x+3/y=15x+3
f-1(x) is an inverse function, which means you gotta swap the x an the y:
x=15y+3
The goal is to get y alone, so you minus 3 on both sides to get
x-3=15y
And then divide both sides by 15 to get y alone
x-3/15=y
Answer:
6/7 - 1/3
Step-by-step explanation:
You know that 1/2=0,5
Then, you have to solve the two sums:
You now know what number of 0,47 and 0,52 is closer to 0,5; which is 0,52
0,47 is to 0,03 from 0,5
0,52 is to 0,02 from 0,5
Answer:
4/5
Step-by-step explanation:
Answer:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Step-by-step explanation:
Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope,

The key is to realize that the wires have some distance to the ground, that does not change.
The pole does change. But the vertical height of the pole plus the distance from the pole to the wires is the distance ground to the wires all the time. In other words, for any angle one has:
D = L * sin(alpha) + d, where D is the distance wires-ground, L is the length of the pole, alpha is the angle, and 'd' is the distance from the top of the (inclined) pole to the wires:
L*sin(40) + 8 = L*sin(60) + 2, so one can get the length of the pole:
L = (8-2)/(sin(60) - sin(40)) = 6/0.2232 = 26.88 ft (be careful to have the calculator in degrees not rad)
So the pole is 26.88 ft long!
If the wires are higher than 26.88 ft, no problem. if they are below, the concerns are justified and it won't pass!
Your statement does not mention the distance between the wires and the ground. Do you have it?
