NARA [144]

rate of change is the slope

slope = (y2-y1)/(x2-x1)

m= (180-120)/(3-2)

m = 60/1

m = 60

b.  point slope form

y-y1 = m(x-x1)

y-120 = 60 (x-2)


c see attached graph.  x>=0 since it is hours

d the y intercept is

y -120 = 60x-120

add 120 to each side

y = 60x

In a population of 400,000 people, 160,000 are infected with a virus. After a person becomes infected and then recovers, the per
Margarita [4]

Answer:

Number of people that will be infected in 4 years is 252,610.

Step-by-step explanation:

The number of people that will be infected in 4 years can be calculated as follows:

Number of people that will be infected in year 1 = 160,000

Number of people that will not be infected in year 1 = 400,000 - 160,000 = 240,000

Number of people that will be infected in year 2 = Number of people that will not be infected in year 1 * 15% = 240,000 * 15% = 36,000

Number of people that will not be infected in year 2 = Number of people that will not be infected in year 1 - Number of people that will be infected in year 2 = 240,000 - 36,000 = 204,000

Number of people that will be infected in year 3 = Number of people that will not be infected in year 2 * 15% = 204,000 * 15% = 30,600

Number of people that will not be infected in year 3 = Number of people that will not be infected in year 2 - Number of people that will be infected in year 3 = 204,000 - 30,600 = 173,400

Number of people that will be infected in year 4 = Number of people that will not be infected in year 3 * 15% = 173,400 * 15% = 26,010

Therefore, we have:

Number of people that will be infected in 4 years = Number of people that will be infected in year 1 + Number of people that will be infected in year 2 + Number of people that will be infected in year 3 + Number of people that will be infected in year 4 = 160,000 + 36,000 + 30,600 + 26,010 = 252,610

Apply Laws of Exponents to write an equivalent expression.<br> (3y)-4. (2z)-4
Stels [109]

After Applying Laws of Exponents we can write as (6yz)^{-4}

<h3>What is law of exponents ?</h3>

The exponent of a number indicates how many times a number has been multiplied by itself. For instance, 34 indicates that we have multiplied 3 four times. Its full form is 3 3 3 3. Exponent is another name for a number's power. A whole number, fraction, negative number, or decimal are all acceptable.

<h3>How are powers of powers multiplied?</h3>

Exponents with distinct bases and the same powers can be multiplied by multiplying the bases and writing the power outside of the brackets.

a^{n} .b^{n} =(a.b)^{n}

=3y^{-4} . 2z^{-4}

=3y^{-4} . 2z^{-4}

= (6yz)^{-4}
