Answer:

10.9

Step-by-step explanation:

You can solve this using the Pythagorean theorem, a^2+b^2=c^2, since it will form a right triangle.

You aren't missing the hypotenuse (c), but one of the side lengths (b). But you still solve like a normal algebraic equation.

Plugging in your values, you should start with 5^2+b^2=12^2

Then square everything.

25+b^2=144

Take away 25 from both sides.

b^2= 119

Then square root both sides.

b= 10.9

Complete these ordered pairs for this equation.<br> (0, ), (-1,), (1, ) y=2x+1<br> Help
N76 [4]

Answer:

(0, 1)

(-1, -1)

(1,3)

Step-by-step explanation:

Given the function;

y = 2x + 1

when x = 0

y = 2(0)+1

y = 1

Hence the required pair is (0, 1)

when x = -1

y = 2(-1) + 1

y = -2 + 1

y = -1

Hence the coordinate is (-1, -1)

when x = 1

y = 2(1) + 1

y = 2 + 1

y =3

Hence the coordinate is (1, 3)

Two ships leave from the same port. One travels west 84 miles and the other travels 62 miles north. Determine the distance betwe
Lerok [7]
The distance the ships traveled are like the legs of a triangle and the question wants to know the hypotenuse. To find the hypotenuse, use the pythagorean theorem. this is a^2 + b^2 = c^2, with a and b being the legs and c being the <span>hypotenuse.
</span>Plug in known values:
84^2 + 62^2 = c^2
Solve:
84^2 = 7056
62^2 = 3844
7056 + 3844 = c^2
7056 + 3844 = 10900
10900 = c^2
Now you just need to isolate c by finding the square root of both sides.
√10900 = 104.403
√c^2 = c

So c = 104.403, or just 104.40 when rounded to the nearest tenth.
And if c is 104.40, then that means the hypotenuse is 104.40.
And all of that basically means that the distance between the ships is 104.40 miles.

May someone please help me out on this question
NISA [10]

Answer:

A

Step-by-step explanation:

It's hard to see but when x is 6, y is 4.5. Just plug that into each equation and see which one is correct.

x^{2} =8y\\x=6;y=4.5\\6^{2} =8(4.5)\\36=36
