PLS ANSWER QUICK! Thanks!

Answer:

The correct answer would be $a=\sqrt{c^2-b^2}$

Step-by-step explanation:

given $a^2+b^2=c^2$ we want to solve for a

How?

We can do this by using basic algebra ( isolating the variable (a ))

Step 1 subtract $b^2$ from each side

$a^2+b^2-b^2=a^2\\c^2-b^2=c^2-b^2$

now we have $a^2=c^2-b^2$

step 2 take the square root of each side

$\sqrt{a^2} =a\\\sqrt{c^2-b^2} =\sqrt{c^2-b^2}$

we're left with $a=\sqrt{c^2-b^2}$

Hence your answer is A

HELP!! 30 POINTS AND WILL MARK BRAINLIEST One month, Henry's grandfather gives him a box of 523 baseball cards. Each month, star

Bezzdna [24]

Answer:

nth term = 523 + 24(n - 1

Step-by-step explanation:

This is modelled by an arithmetic series where first term a1 = 523 and common difference d = 24.

nth term = a1 + d(n - 1).

Here it is 523 + 24(n - 1) (answer)

What type of conic section is given by the equation 4x^2+9y^2=36? What are its domain and range?

Damm [24]

$4x^2+9y^2=36\\
\\
\frac{4x^2}{36}+\frac{9y^2}{36}=\frac{36}{36}\\
\\
\boxed{\frac{x^2}{9}+\frac{y^2}{4}=1}$

This is a equation of a ellipse (0,0) centered
