Translate and solve: eight more than the product of three and a number is -13
Murrr4er [49]
Ok, so let’s take the given phrase.
Eight more than the product of 3 and a number is -13. A translation to numbers looks like this:
3x + 8 = -13
Now, let’s solve for x. We can start the process by subtracting 8 from both sides.
3x = -21
now, we will divide each side by 3 to isolate the variable, thus solving for x.
x = -7

Answer:

The population of Bear in 2050 is 4750000

Step-by-step explanation:

A) The exponential growth equation for bear is as follows -

dN/dT = rmax * N

Where dN/dT = change in population

rmax is the maximum rate of change

N = Base population

B) Here the per capita rate of increase (r) will always be a positive value irrespective of the and hence we will assume this population to be growing exponentially.

C) dN/dT = rmax * N

D) dN / 5 = 2.5 * 380,000

dN = 5*2.5 * 380000

= 4750000

Answer:

  • D. 8

Step-by-step explanation:

  • DC = AC = x is the radius

<u>Using the Pythagorean theorem, find x:</u>

  • (x + 9)² - x² = 15²
  • x² + 18x + 81 - x² = 225
  • 18x = 225 - 81
  • 18x = 144
  • x = 144/18
  • x = 8
