Step-by-step explanation:
General equation of circle:
(x - a)² + (y - b)² = r².
Therefore we have x² + (y - 3.5)² = 12.25.
Answer:
A
Step-by-step explanation:
Because a^2+b^2=c^2 in a right triangle by Pythagorean's Theorem. So, the only one that works is 3^2+4^2=5^2 because 9+16=25.
All real numbers. in interval notation, that's (<span><span>−∞</span>, ∞</span><span>). there isn't a value you could insert for "x" that would give you an error.</span>
![\sqrt[8]{48^4}](https://tex.z-dn.net/?f=%20%5Csqrt%5B8%5D%7B48%5E4%7D%20)
can be rewritten as

to the

power:

Now, applying exponent rules (multiply exponent inside parentheses by the one outside parentheses), we get:

This is equivalent to

, so now, we just simplify:

So:
Answer:
9
Step-by-step explanation:
8X+4=360-108-80-96
8X+4=76
8X=76-4
8X=72
X=72/8
X=9
