Answer:
Step-by-step explanation:
We don't need choices to find out the correct answer. Solve this problem by completing the square. Begin by setting the quadratic equal to 0 and moving over the constant, like this:
and factor out the -1 in front of the x-squared, since the leading coefficient HAS to be a 1:
Now take half the linear term, square it, and add it to both sides. Our linear term is -2. Half of -2 is -1, and squaring that gives us 1. So we add a 1 into both sides. But that -1 out front there on the left is a multiplier, so what we actually added in was -1(1) which is -1:
On the left side we have a perfect square binomial, which is why we do this, and on the right side we have -2:
and we can move that constant back over and set the quadratic back equal to y:
which gives us a max height of 2.
(If this was modeling parabolic motion, we would know that the time it takes to get to that max height is 1 second. The vertex of this parabola is (1, 2))

its c bc it starts at 30
Step-by-step explanation:
3² = x + 5. The equivalent equation to log₃(x+5) = 2 is 3² = x + 5.
In order to solve this problem we have to know about Logarithm.
Logarithm is defined as the exponent of a power with a certain base, that is, the number to which a given base must be raised to obtain a given result.
logₐ b = x ----------> aˣ = b
Solving for log₃(x+5) = 2 where a = 3, x = 2, and b = x + 5
3² = x + 5
