Answer: PN = 8√2 ≈ 11.3
<u>Step-by-step explanation:</u>
Perimeter of a square: P = 4s
Given: P = 64 → 64 = 4s
16 = s
Using the 45-45-90 rule: If the sides are 16, then the hypotenuse (diagonal) = 16√2
Since we only need half of the diagonal, (16√2)/2 = 8√2 ≈ 11.3

Answer: Choice C) 40 </h3>
==========================================================
Work Shown:
Plug in x = 0
This indicates that (0,1) is on the curve. This is the y intercept.
Do the same for x = 2
So we know that (2,81) is another point on this curve.
We need to find the slope of the line through (0,1) and (2,81) to get the slope of the secant line we want.
The slope of the line through (0,1) and (2,81) is m = 40. This value of m is exactly the slope of the secant line your teacher is asking for. This is why the answer is choice C.
Answer:
Step-by-step explanation:
<u>Trapezoid area formula:</u>
<u>Substitute values:</u>
- 7598 = 1/2(127 + 105)h
- 7598 = 116h
- h = 7598/116
- h = 65.5 cm
Answer:
the area of a triangle = 19 km²
Step-by-step explanation:
area of a triangle = 1/2 b h
where b = 5km
h = 7.6 km
plugin values into the formula:
A = 1/2 (5) 7.6
A = 19 km²
therefore,
the area of a triangle = 19 km²
