Answer:
-1/32
Step-by-step explanation:
To evaluate the expression, substitute x = 2 and y = -4. Then use exponent rules to simplify. Review the rules here:
To evaluate or simplify expressions with exponents, we use exponent rules.
1. An exponent is only a short cut for multiplication. It simplifies how we write the expression.
2. When we multiply terms with the same bases, we add exponents.
3. When we divide terms with the same bases, we subtract exponents.
4. When we have a base to the exponent of 0, it is 1.
5. A negative exponent creates a fraction.
6. When we raise an exponent to an exponent, we multiply exponents.
7. When we have exponents with parenthesis, we apply it to everything in the parenthesis.
We will use these rules to simplify.
Answer:
A) r=2t
B) 4t²
C) 4(30)² which will end up being 11310 in²
Step-by-step explanation:
A) If it increases 2 inches every minute, you would take that and put it with the t, aka time.
B) A=r² which will translate into A=
(2)²
C) You take the half-hour, which is 30 minutes, and translate that into t then place that into your calculator and get an answer of 11,309.73 and then round up to the whole number
