$\bf \underset{155-128}{155-2^7}= 27\qquad \qquad therefore\qquad 2^7+27=155\implies 2^7+3^3=155$

Solve and plot your answer on the number line below: 7.08 + 2x=15.96

NemiM [27]

7.08 + 2x =15.96
-7.08. -7.08
-------------------------
2x=8.88 divide each by 2

X=4.44
You would plot it in between 4 and 5 but on one of the line marks depending on what there value are

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

Last year's computer models are discounted 20%. What was the original price to the nearest dollar of a computer that now costs $

Alisiya [41]

Answer:

Step-by-step explanation:

<h3>If the Original price was $ X , Then </h3>

$x - 0.20x \: = 1480$

$0.8x = 1480$

$x = 1480 \div 0.8$

<h3>So , X = 1850 dollars .</h3>

On a highway, you take 3 seconds to increase your speed from 32 to 35 miles per hour. Your speed increases the same amount each

balandron [24]

Answer:

1 to 30 seconds

Step-by-step explanation:

3 seconds increases your speed from 32 to 35 miles per hour

Hence 3 seconds = 3 miles per hour(35-32 miles)

1 second = 1 mile

The function for the increase per mile is therefore:

f(x)= 1x

Where x is number of seconds travelled on the highway

The domain of a function are the possible input values for x. Since the speed limit on the highway is 65 miles, the input values for x cannot be more than 30 seconds(current speed is 35 miles per hour, 65-35=30)
