A piece of wire is 8/9 meter long broke into two pieces. One piece is 2/3 meter long. How long is the other?

Genrish500 [490]

Answer:

<h2>2/9 is the answer.</h2>

Step-by-step explanation:

1. First, make an equation.

Given:

8/9 = length of wire

2/3 = length of a part of the wire

E = 8/9-2/3

Unknown:

Second part of wire

2. Make the numbers have equal denominators

2/3 * 3/3

= 6/9

3. Solve

8/9 - 6/9

= 2/9

Hope this helped,

Find a polar equation for the curve represented by the given Cartesian equation. (Use t in lieu of θ in your answer.) x2+y2=8cx

pochemuha

Answer:

The polar equation of the curve is:

$r=8c*cos(\theta)$

Step-by-step explanation:

In polar form x and y could be written as:

$x=rcos(\theta)$

$y=rsin(\theta)$

Taking the square of each value we have:

Let's recall that $cos^{2}(\theta)+sin^{2}(\theta)=1$

$x^{2}+y^{2}=r^{2}(cos^{2}(\theta)+sin^{2}(\theta))$

$x^{2}+y^{2}=r^{2}$

Then, the cartesian equation is rewritten as:

$x^{2}+y^{2}=8cx$

$r^{2}=8c*rcos(\theta)$

Therefore, the polar equation of the curve is:

$r=8c*cos(\theta)$

I hope it helps you!

Find the length of the hypotenuse using pythagorean theorem

Delvig [45]

A2 + b2 = c2

7^2 + 5^2 = c2

49 + 25 = c2

74 = c2

square root of 74 = c2

8.602325267 = c

The length of the hypotenuse is around 8.6 cm.
