Answer:

x = 12

Step-by-step explanation:

Lets set up the equation!

Complementary angles equal 90 degrees.

2x + 20 + 3x + 10 = 90

Now lets combine the like terms!

2x + 3x 20+ 10

5x +30 = 90

Now subtract 30 from both sides!

5x = 60

Divide each side by 5

x = 12

Brainliest is appreciated!

Help please asap aaaaaaaaaaaaaaaaaa
wel

Answer:

Step-by-step explanation:

Your exponential formula is in the form y = ab^x. In this form, the coefficient 'a' is the initial value, the y-intercept, the value when x=0. The value 'b' is the growth factor, which is 1 more than the growth rate per increment of x. This problem is asking for the growth rate to be expressed as a percentage.

__

Given p(x) = 78500(1.02^x), we can compare to the exponential function form to see that ...

  • a = 78,500
  • b = 1.02 = 1 +0.02 = 1 +2%

The value of x is zero in the year 2000, so the population that year is ...

  p(0) = a = 78,500

The increase per year is the value of 'b' with 1 subtracted:

  growth rate = 2% per year
