Answer:

The answer is 20.27

Step-by-step explanation:

Assuming you are talking about the pythagorean theorem, the equation is

a^2 + b^2 = c^2

Plug the values of a and b into the problem and solve.

(20)^2+ (√11 )^2=c^2

That can be further simplified to

400+11

as 20 * 20 is 400 and √11 *√11 is 11.

Then you add those answers together which equals

411

Remember that 411 is equal to c^2.

To solve for c you have to take the square root of the equation.

√411=√(c^2)

When simplified √(c^2) is

20.27313493

Now rounding to the nearest hundredth means the second decimal place is what you round to.

The second decimal place is where the 0.07 is at. 3 is closer to .07 than to 0.08 so you round down.

The answer is thus 20.27

What is the equation of this graphed line?

maksim [4K]

Answer:

$y=-\frac{9}{8} x+7$

Step-by-step explanation:

The slope is found by doing the equation $\frac{rise}{run}$ . When looking at the first two points, it's shown that the rise (difference between the two y values) is -9 (since it decreased by 9) and the run (difference between the two x values) is 8 (since it increased by 8). This makes the slope equal $-\frac{9}{8}$ .
