Answer:

The correct option is C: 15,040(1.21)t ≤ 100,000

Step-by-step explanation:

Consider the provided information.

It is given that after 7 a.m power usage on a college campus increases at a rate of 21% per hours.

Let t is the number of hours then the rate of increase will be:

21\%t=\frac{21}{100}t=0.21t

Prior to 7 a.m., 15,040 kWh have been used. Thus the increment of power use after t hours will be:

Increase=15,040(0.21)t

The total power consumption will be:

Previous power consumption + increase in power

15,040+15,040(0.21)t\\=15,040(1+0.21)t\\=15,040(1.21)t

The power usage on campus will be less than or equal to 100,000.

15,040(1.21)t\leq 100,000

Hence, the required inequality is 15,040(1.21)t\leq 100,000.

Thus, the correct option is C: 15,040(1.21)t ≤ 100,000

The power increases by 21% per hour. 21% written as a decimal is 0.21.

Because it increases you would multiply the starting value by 1.21 times the number of hours (t).

That needs to be less than or equal to 100,00

The equation would be:

C: 15,040(1.21)t ≤ 100,000

Find a quadratic function that includes the set of values below.<br> (0,9). (2,15) (3,12)
nlexa [21]

Answer:

f(x) = -2x^2 + 7x + 9

Step-by-step explanation:

f(x) = ax^2 + bx + c\\f(0) = 9 => c = 9;\\f(2) = 15 = 4a + 2b + 9  2a + b  = 3\\f(3) = 9a + 3b + 9 = 12  3a + b = 1\\Subtract the second equation from the first:\\-a = 2 => a = -2; b = 7; c = 9\\f(x) = -2x^2 + 7x + 9

What is five x plus negative three equals fifteen
bearhunter [10]
You write the equation like this:
5x + (-3) = 15

But if you want to solve it then you do it like this:
5x + (-3) = 15
5x - 3 = 15
5x = 18
x = 18/5
