Answer:

A point (a, b) rotated around a point (x, y) 180 degrees will transform to point (-(a - x) + x, -(b - y) + y). A point (a, b) rotated around the origin 270 degrees will transform to point (b - y + x, -(a - x) + y).

In Japan. traditionally it was believed that if you folded 1,000 origami cranes, your wish would come true. For a party, Emika i
vfiekz [6]

Answer:

Step-by-step explanation:

Remark

Interesting detail.

Origami Paper is square -- perfectly.

So the properties listed will be related to a square.

Givens

Area = 35 in^2

Formulas

Area = s^2  where s is the length of 1 side.

Perimeter = 4s

Solution

<u>Area = s^2 = 35</u>

s^2 = 35                     Take the square root of both sides.

√s^2 = √35

s = 5.91

<u>Perimeter = 4s</u>

s = 5.91

Perimeter = 4*5.91

Perimeter = 23.66

The way the question is worded, the answer you should submit is

Perimeter = 4 * √35

Compute the lower Riemann sum for the given function f(x)=x2 over the interval x∈[−1,1] with respect to the partition P=[−1,− 1
Nata [24]

Answer:

21/64

Step-by-step explanation:

First, we need to note that the function f(x) = x² is increasing on (0, +∞), and it is decreasing on (-∞,0)

The first interval generated by the partition is [-1, -1/2], since f is decreasing for negative values, we have that f takes its minimum values at the right extreme of the interval, hence -1/2.

The second interval is [-1/2, 1/2]. Here f takes its minimum value at 0, because f(0) = 0, and f is positive otherwise.

Since f is increasing for positive values of x, then, on the remaining 2 intervals, f takes its minimum value at their respective left extremes, in other words, 1/2 and 3/4 respectively.

We obtain the lower Riemman sum by multiplying this values evaluated in f by the lenght of their respective intervals and summing the results, thus

LP(f) = f(-1/2) * ((-1/2) - (-1)) + f(0) * (1/2 - (-1/2)) + f(1/2)* (3/4 - 1/2) + f(3/4) * (1- 3/4)

= 1/4 * 1/2 + 0 * 1 + 1/4 * 1/4 + 9/16 * 1/4 = 1/8 + 0 + 1/16 + 9/64 = 21/64

As a result, the lower Riemann sum on the partition P is 21/64
