Answer:

You are drawing a right triangle. So draw the two lines off of the right angle. Then write 5 along one line. That line is now BC, so you can start naming points and putting in lengths. Then, draw the hypotenuse (AB) going from the end of the line you were writing next to, to the other line. Make sure it is at least twice as long, because it is 13 long. Then, to find the length of the last line, square 13, and subtract 25 from it. Take that number and find it's square root. You should get 12, which is your answer.

Determine if (-1,9) and (-2,6) are solutions to the system of equations: x + y = 8 x2 + y = 10 A) Both are solutions B) Neither

Dahasolnce [82]

Answer:

D) Only (-1,9) is a solution.

Step-by-step explanation:

x+y =8

x^2 + y = 10

Lets check the first point (-1,9)

Put in x =-1 y =9

x+y =8

-1+9 = 8

8 =8

This works

x^2 + y = 10

(-1)^2 +9 =10

1+9 = 10

10 = 10

This works

Lets check the second point (-2,6)

Put in x =-2 y =6

x+y =8

-2+6 = 8

4=8

This does not work

We can stop now. (-2,6) cannot be a solution

Find the area and the circumference of the circle with the radius 6yd.

fgiga [73]

Answer:

Step-by-step explanation:

The formula of an area of a circle:

$A=\pi r^2$

The formula of a circumference of a circle:

$C=2\pi r$

<em>r</em><em> - radius</em>

<em />

We have <em>r = 6yd</em>.

Substitute:

$A=\pi(6^2)=36\pi\ yd^2$

$C=2\pi(6)=12\pi\ yd$

If you want round the answers, then use <em>π ≈ 3.14</em>

$A\approx(36)(3.14)=113.04\ yd^2$

$C\approx(12)(3.14)=37.68\ yd$

The Surface Area of this cylinder rounded to the nearest square

kipiarov [429]

Answer:

1728

Step-by-step explanation:

2 $\pi$ r h

2 $\pi$ (11) × 14

968

B= $\pi r^{2}$

B= $\pi$ 11^2 =121 $\pi$

S=2 $\pi$ rh + 2 $\pi r^{2}$

S=968 +2 x 121

S=968 +242 $\pi$ = 1728
