Answer:
Only J and I
Step-by-step explanation:
Transversal Lines are only transversal to sets of parallel lines in which they pass through and P is not parallel to any.
Answer:
-1
Step-by-step explanation:
The formula to find the slope of a line is:

where (x1, y1) and (x2, y2) are points on the line. We can substitute the points (-10, 0) and (-13, 3) into the formula and simplify:

This means the slope of the line is -1.
The parametric equations for x and y describe a circle of radius 10 m, so the length of the base of the fence is the length of the circumference of a circle of radius 10 m. The formula for that circumference (C) is ...
... C = 2πr
... C = 2π·(10 m) = 20π m
The height as a function of angle (t) is found by substituting for x and y.
... h(t) = h(x(t), y(t)) = 4 + 0.01·((10cos(t))²-)10sin(t))²) = 4+cos(2t)
The average value of this over the range 0 ≤ t ≤ 2π is 4, since the cosine function has two full cycles in that range, and its average value over a cycle is zero.
Thus, the area of one side of the fence is that of a rectangle 20π m long and 4 m wide. That will be
... (20π m)·(4 m) = 80π m²
The amount of paint required to cover both sides of the fence is
... 2×(80π m²)×(1 L)/(10 m²) = 16π L ≈ 50.3 L
_____
You can work out the integral for area as a function of t. When you do, you will find it gives this same result.
Answer:
46 degrees
Step-by-step explanation:
180 - 102 - 32 equals to 46
Hi!
If the perimeter of the triangle is 41, then x is:
5x + 2 + 6x - 3 + 3x = 41
5x + 6x + 3x = 41 + 3 - 2
14x = 42
x = 42/14
x = 3
The x is 3.
