For each equation, enter two more equations using the same numbers that express the same relationship in a different way. 3+2=5

Zepler [3.9K]

Answer:

$3 = 5 - 2$

$2 = 5 - 3$

Step-by-step explanation:

Given

$3 + 2 = 5$

Required

Express in different ways

The first way is:

$3 + 2 = 5$

Subtract 2 from both sides

$3 + 2 -2= 5 - 2$

$3 = 5 - 2$ ------ (1)

Another way is:

$3 + 2 = 5$

Subtract 3 from both sides

$3 - 3 +2 = 5 - 3$

$2 = 5 - 3$ --- (2)

A biologist observed a population of bacteria that grew at a rate expressed by the exponential equation

bearhunter [10]

Answer:

<em>It will take 26.34 minutes for the population to reach 5 times its initial value</em>

Step-by-step explanation:

<u>Exponential Growing</u>

The population of bacteria grows at a rate expressed by the equation:

$f(t)=256e^{0.06111t}$

Where t is in minutes.

We need to know when the population will reach 5 times its initial value. The initial value can be determined by setting t=0:

$f(0)=256e^{0.06111\cdot 0}=256\cdot 1=256$

Now we find the time when the population is 5*256=1,280. The equation to solve is:

$1,280=256e^{0.06111t}$

Dividing by 256:

$e^{0.06111t}=1,280/256=5$

Taking natural logarithms:

$ln\left(e^{0.06111t}\right)=ln5$

Applying the logarithm properties:

$0.06111t=ln5$

Solving for t:

$t=ln5/0.06111=26.34$

It will take 26.34 minutes for the population to reach 5 times its initial value

If josh can run 2 miles in 15 minutes. How many miles can he run in 2 hours?

Fantom [35]

Answer:

900

Step-by-step explanation:

Because the unit rate of mins per mile is 7.5 min for each mile. So, then you multiply 120 with 7.5 and move the decimal place to get
