Pythagorean theorem: find the perimeter

Mathematics
1 answer:
denis-greek [22]3 years ago
3 0
The answer is 5
Explanation:
We need to use the Pythagorean,
a^2 + b^2 = c^2
Where c is the hypotenuse
We can fill in spots now 12^2 + b^2 = 13^2
And then we solve 144 + b^2 = 169
Next we get b^2 alone
169-144=25
So we get b^2=25
For the final step you have to find the square root of 25 to get b alone which is 5

Which system of equations does this graph represent?
jeyben [28]

Answer:

1

Step-by-step explanation:

First, we can find the equation of the parabola. The standard form of a parabola is ax^2 + bx + c,

where c is the y-intercept. The y-intercept on the graph is -5, and every option starts with x^2, so the equation must be x^2 - 5. This rules out options 3 and 4.

Next, we can find the equation of the line. The options are all given in slope-intercept form: y = mx + b, where b is the y-intercept. The y-intercept on the graph is 1, and option 1 has 1 in the place of b. Therefore, option 1 is the answer.

Whats the distance between (-8,-7) (8,-4)
balandron [24]
To find the distance between points, use the distance formula.

Distance formula: \sqrt{ (x_{2} -  x_{1})^{2} + ( y_{2} -  y_{1})^{2} }

Plug in your values for x_{2},  x_{1},  y_{2},  y_{1} using (-8, -7) and (8, -4) and solve.

\sqrt{(8 - (-8))^{2}+(-4 - (-7))^{2}}
\sqrt{(8+8)^{2}+(-4+7)^{2}}
\sqrt{(16)^{2}+(3)^{2}}
\sqrt{256+9}
\sqrt{265} ≈ 16.28

Answer:
Approximately 16.28 units.

Which statement about the greatest common factor of 32n2 and 56n is true?
Lisa [10]

Answer:

It is 8n, because there is no greater term that is the factor of both 32n2 and 56n.

Step-by-step explanation:

The greatest common factor of the two expression is the term 8n.

It is the highest factor of both expressions that will divide them.

Given:

                32n²             56n

Factor them:

           2n(16n            28)

            4n(8n             14)

            8n(4n             7n)  - Beyond this, no common factor can divide them both.

Therefore 8n is the greatest common factor of the two.
