ANSWER
The other zero is

EXPLANATION
The axis of symmetry serves as the midpoint of the two zeroes.
We were given that the axis of symmetry of the quadratic equation is

We were also given that, one of the zeroes of the quadratic equation is

Let the other zero of the quadratic equation be

,then, we apply the midpoint formula to find the value of

Since it is the x-values of the intercepts that gives the solution, we use only the x-value part of the midpoint formula which is given by,

We substitute to obtain,

We multiply through by 2 to get,

This implies that,

The formula for exponential growth is written as y = a(1 + RATE)^time
where a is the starting value, rate is the percentage of growth written as a decimal and time in this case would be the number of days.
You are given the growth rate as 11% and the starting day was day 1.
Since the table only goes to 10 days, you can use 10 as the time, or use X as an exponent if you need to calculate more than 10 days.
Using all this information, the formula becomes y = 1(1.11)^10 for 10 days or y = 1(1.11)^x for any number of days needed.

Answer:
∠ BOC = 40°
Step-by-step explanation:
∠ AOC = 90° , then
5x + 2x + 20 = 90
7x + 20 = 90 ( subtract 20 from both sides )
7x = 70 ( divide both sides by 7 )
x = 10
Then
∠ BOC = 2x + 20 = 2(10) + 20 = 20 + 20 = 40°
