Part A Prove that when x > 1, a triangle with side lengths a = x2 − 1, b = 2x, and c = x2 + 1 is a right triangle. Use the Py

Nataly [62]

Step-by-step explanation:

Given : A triangle with side lengths $a = x^2-1, b = 2x, \text{ and } c = x^2 + 1$

To find : Prove that when x > 1, it is a right triangle. Use the Pythagorean theorem and the given side lengths to create an equation. Use the equation to show that this triangle follows the rule describing right triangles. Explain your steps ?

Solution :

For right triangle the Pythagorean theorem is to be satisfied.

i.e. $c^2=a^2+b^2$

Here, $a = x^2-1, b = 2x, \text{ and } c = x^2 + 1$

Substitute the values,

$(x^2+1)^2=(x^2-1)^2+(2x)^2$

$x^4+1+2x^2=x^4+1-2x^2+4x^2$

$x^4+1+2x^2=x^4+1+2x^2$

LHS=RHS

It is a right triangle.

b. If each square has a side length of 61 cm, write an expression for the surface area and another for the volume of the figure

Blababa [14]

Answer:

6*(61^2) and 61^3

Step-by-step explanation:

If the squares have a side length of 61 (assuming this is a cube) our surface area is 6*(61^2) because each side is a square and there are six sides.

As for the volume, we have 61^3.

Hope this was helpful.

Sundas made 2 out of her 5 shots she attempted. Find the percent of the shots she attempted.

Rudik [331]

Answer:

<u>i think</u> it is 40%

Step-by-step explanation:

she made 2/5 shots so

2/5*2=4/10

i times it by 2 because its out of 100

4/10*10=40/100

then i times it by 10 to get to 100

(2/5 is not 2 divided by five it is 2 over 5 just incase u didnt know what i was talking about)

Let v1=(1, 6) and v2=(5, -3)

astraxan [27]

Answer:

See Explanation;

Step-by-step explanation:

The given vectors are;

$v_1=\:\:$ and $v_2=\:\:$

a) To add or subtract two vectors, we add or subtract their corresponding components

$v_1+v_2=\:\:+\:\:$

$v_1+v_2=\:\:$

$v_1-v_2=\:\:-\:\:$

$v_1-v_2=\:\:$

$v_2-v_1=\:\:-\:\:$

$v_2-v_1=\:\:$

b) See attachment for graphs(1,6
