I assume you mean:
3x^2 -5xy + 5y^2.
Simply substitute the given values into the equation:
3(-6)^2 - 5(-6)(2) + 5(2)^2
=188
Answer: 0 radians
Explanation: Looking at the unit circle, tan and sin equal each other at 0 radians. Sin(0) = 0 and tan(0) = 0/1 = 0.
Therefore, theta equals 0. Multiplying by 3 does not matter in this case because it is being multiplied by 0. Any number multiplied by 0 is 0.
Answer:
<h2>$4.7</h2>
Step-by-step explanation:
step one:
Let the cost be y
to solve for the cost of a movie ticket, we need to solve the expression
y=2.75+0.10x
step two:
given that x is the number of years between 1980-2000
the number of years is 20years
put x= 20 in the expression for the cost we have
y=2.75+0.10(20)
y=2.7+2
y=$4.7
