Answer:

12.56

Step-by-step explanation:

The shape is 1/4 of a circle.

The arc length is 1/4 of the whole circle’s circumference.

$C=3.14 \times d$

$r=8$

$d=2r\\d=2(8)\\d=16$

$1/4 \times 3.14 \times 16$

$=12.56$

Answer:

12.56

Step-by-step explanation:

1. Circumference equation: 2πr

2. Substitute radius in equation: 2•8π

3. Simplify: 16π, or 50.24

4. Divide by 4, since you only need to find 1/4 of the circumference: 12.56

Answer:

Line segment AD

$AD = \sqrt{(c-0)^{2}+(d-0)^{2}}$

$AD = \sqrt{c^{2}+d^{2}}$

Line segment BC

$BC = \sqrt{[(b+c)-b]^{2}+(d-0)^{2}}$

$BC = \sqrt{c^{2}+d^{2}}$

Line segment AB

$AB = \sqrt{(b-0)^{2}+(0-0)^{2}}$

$AB = \sqrt{b^{2}+0^{2}}$

$AB = b$

Line segment CD

$CD = \sqrt{[c-(b+c)]^{2}+(d-d)^{2}}$

$CD = \sqrt{b^{2}+0^{2}}$

$CD = b$

Step-by-step explanation:

We defined the length of each side by the Equation of the Line Segment, which is a particular case of the Pythagorean Theorem. Let $A(x,y) = (0,0)$ , $B(x,y) = (b,0)$ , $C(x,y) = (b+c, d)$ and $D(x,y) = (c,d)$ , we construct the equations below:

Line segment AD

$AD = \sqrt{(c-0)^{2}+(d-0)^{2}}$

$AD = \sqrt{c^{2}+d^{2}}$

Line segment BC

$BC = \sqrt{[(b+c)-b]^{2}+(d-0)^{2}}$

$BC = \sqrt{c^{2}+d^{2}}$

Line segment AB

$AB = \sqrt{(b-0)^{2}+(0-0)^{2}}$

$AB = \sqrt{b^{2}+0^{2}}$

$AB = b$

Line segment CD

$CD = \sqrt{[c-(b+c)]^{2}+(d-d)^{2}}$

$CD = \sqrt{b^{2}+0^{2}}$

$CD = b$

Select the correct answer from each drop-down menu. f(x) = x2 − 8x + 15 g(x) = x − 3 h(x) = f(x) ÷g(x)

Serggg [28]

The answer is x - 5

To solve (x^2 - 8x + 15) /(x - 3) you factor the numerator and denominator and cancel the common factors.

Pythagorean theorem. A^2+B^2=C^2.

So 12^2+16^2=c^2

144+256=c^2

400=c^2

square root of 400=c

So C=20

Crank

Answer:

It began after the stock market crash of October 1929, which sent Wall Street into a panic and wiped out millions of investors. Over the next several years, consumer spending and investment dropped, causing steep declines in industrial output and employment as failing companies laid off workers.
