Estimate the product of<br> 5<br> and 4<br> Then find the product.
Nana76 [90]

1: Look at the 4, its a lot easier to multiply 5 x 5 rather than 5 x 4, plus if you are estimating, you are going to round either up or down.

2: Multiply 5 x 5 // the answer is 25.

3: Multiply 5 x 4 (the original) // which is 20.

Use what you've learned in this unit to model the population of Western
nekit [7.7K]

The population function of the Western Lowland Gorillas can either represent population growth or population decay

<h3>How to model the population</h3>

The question is incomplete, as the resources to model the population of the Western Lowland Gorillas are not given.

However, the following is a general guide to solve the question.

An exponential function is represented as:

y = a(1 \pm r)^x

Where:

  • (a) represent the initial value i.e. the initial population of the Western Lowland Gorillas
  • (r) represents the rate at which the population increases or decreases.
  • (x) represents the number of years since 2022
  • (y) represents the population in x years

Given that the population of the Western Lowland Gorillas decreases, then the rate of the function would be 1 -r (i.e. an exponential decay)

Take for instance:

y = 2000 * 0.98^x

By comparison.

a = 2000 and 1 - r = 0.98

The above function can be used to model the population of the Western Lowland Gorillas

Angle Relationships Worksheet #2 Back Side J
FinnZ [79.3K]

See answers below.

Step-by-step explanation:

Here apply the relationship of angles formed on a straight line.Angles formed on a straight line add up to 180°

13. m∠1 = 180° - 68° = 112°

14. m∠3=180°-122°=68°

15. m∠4=180°-(68°+90) = 180°-158°=22°

16. m∠5=90° ⇒right-angle

17.

Finding the value of x will require you to equate the sum of the expressions for the two angles to 180°

(2x+11)° + (6x-7)°=180°

2x+6x+11-7=180°

8x+4=180°

8x=180°-4°

8x=176°

x=176°/8 = 22°

Hence ;

∠MHT = (6x-7)°

           =(6*22 -7)°

           =(132-7)°

           =125°

and

∠AHM = (2x+11)°

           = (2*22 +11)°

           = 44 + 11 = 55°
