Hi there!

The answer is C.
{x}^{2} - 14x + 45 = (x - 9)(x - 5)

To find our answer we are looking for 2 integers. The sum of the integers must be -14 (since it must be equal to the number before the variable x). The product of both integers must be 45. Now we can conclude we are looking for the numbers -9 and -5.

- 9 + - 5 = - 9 - 5 = - 14 \\ - 9 \times - 5 = 45

(Remember that multiplying 2 negatives makes you end up with a positive.)

~ Hope this helps you!

An airplane climbs at an angle of 13 with the ground . What is the distance it has traveled when it has attained an altitude of
nevsk [136]
The distance traveled is the hypotenuse of the right triangle formed with the ground.

sinα=400/d

d=400/sinα, we are told α=13° so

d=400/sin13 ft

d≈1778ft (to nearest whole foot)

The population of a small town can be modeled by the equation where t is the number of years since the collection of the populat
liberstina [14]

The true statements is the population was 4800 when the collection of data began. (3rd option)

<h3>What is an exponential function?</h3>

An exponential equation can be described as an equation with exponents. The exponent is usually a variable.

The general form of exponential equation is f(x) = e^{x}

Where:

  • x = the variable
  • e = constant

When a population grows at an exponential rate, it usually has compound rate of growth. Compound growth refers to the geometric progression of a variable.

The exponential equation used to represent an exponential growth usually have this form:

FV = PV (1 + r)^n

Where:

  • FV = future population
  • PV = present population
  • r = rate of growth
  • n = number of years

Given this exponential equation : f(x) = 4800 (1.02)^t

  • 4800 = initial population or population when the data collection began
  • 2 % = rate of growth
  • t = number of years
