Answer: x = 34°

Explanation:

As per definition, complementary angles add up 90°.

In the figure you see angle A measures x + 22° and angle B measures x.

Therefore, according to the definition, you can set this equation:

x + 22° + x = 90°

Solve for x:

start: x + 22 + x = 90
combine like terms: 2x + 22 = 90
subraction property: 2x = 90 - 22
do the operation: 2x = 68
division propery: x = 68/2
do the operation: x = 34

Answer: x = 34°

Akimi4 [234]

The question might have some mistake since there are 2 multiplier of t. I found a similar question as follows:

The population P(t) of a culture of bacteria is given by P(t) = –1710t^2+ 92,000t + 10,000, where t is the time in hours since the culture was started. Determine the time at which the population is at a maximum. Round to the nearest hour.

Answer:

27 hours

Step-by-step explanation:

Equation of population P(t) = –1710t^2+ 92,000t + 10,000

Find the derivative of the function to find the critical value

dP/dt = -2(1710)t + 92000

= -3420t + 92000

Find the critical value by equating dP/dt = 0

-3420t + 92000 = 0

92000 = 3420t

t = 92000/3420 = 26.90

Check if it really have max value through 2nd derivative

d(dP)/dt^2 = -3420

2nd derivative is negative, hence it has maximum value

So, the time when it is maximum is 26.9 or 27 hours
