What is the length of the unknown leg in the right triangle?

Mathematics

ankoles [38]2 years ago

Answer:

3

Step-by-step explanation:

The Pythagorean Theorem can be used to determine an unknown side of a right triangle when two sides are known.

It states that a^2+b^2=c^2.

This is where a and b are the legs of the triangle, and c is the hypotenuse.

If you're unclear on this, you can draw a diagram to help you visualize it.

Hence, we can plug the given information into this formula.

a^2+8^2=(√73)^2

Simplify.

a^2+64=73

Subtract 64 from both sides.

a^2+64-64=73-64

a^2=9

Find the square root of both sides.

a=3

The length of the unknown leg in the right triangle is 3 units.

Use the recursive formula f(n) = 0.4 . f(n-1) + 12 to determine the 2nd term if f(1) = 4.
Irina18 [472]

Answer:

Assuming you have f(n)=0.4f(n-1)+12 with f(1)=4, the answer is f(2)=13.6.

Step-by-step explanation:

I think that says f(n)=0.4f(n-1)+12 with f(1)=4.

Now we want to find f(2) so replace n with 2:

This gives you:

f(2)=0.4f(2-1)+12

f(2)=0.4f(1)+12

f(2)=0.4(4)+12

f(2)=1.6+12

f(2)=13.6

Class be boring but anyways what is ( 2 x 2 − 1 )?
mina [271]

Answer:

3

Step-by-step explanation:

In order to do this equation, your first step is to use the Order of Operations, or PEMDAS, which means that you multiply (M) two times two first before subtracting the equation (S). 2 times 2 is 4.  4 - 1 = 3. Hope I helped! :)
