There is a hole at x=4 because the top factors to (x-4)(x+3)
in the end we get
f(x)=(x-4)(x+3)/(x-4)
the (x-4) cancels out and we get
f(x)=x+3
so baiscally f(x) is y=x+3 but with a hole at (4,7)
one way is to make a piecewise function defined as(x^2-x-12)/(x-4) for all x≠4 and defined as 7 for x=4
or, to just do f(x)=x+3
The answer is 7/1, when you want to know a reciprocal, all you do to the fraction is flip it around. Hope this Helps!
P = 2l + 2w
p-2w = 2l
p-2w/2 = l
Substitute the perimeter and you should be able to work it out
Answer:
The tent is 1.0233 m tall.
Step-by-step explanation:
The rope, the ground and the tent form a right triangle, where the rope is the hypothenuse and the height of the tent is the opposite side to the angle of 17 degrees. We can apply the sine relation on a right triangle to determine the height of the tent, as shown below:
sin(angle) = opposite side / hypothenuse
sin(17) = h / 3.5
h = 3.5*sin(17)
h = 3.5*0.2923 = 1.0233 m
The tent is 1.0233 m tall.
