bacteria colonies can triple in size every 4 days. If you start with 150 bacteria microorganisms, how large with the colony be a

-Dominant- [34]

It triples in size every 4 days. In 16 days it will be 3 * 3 * 3 * 3 times bigger.

3 * 3 * 3 * 3 = 81
Therefore, after 16 days, the colony will contain (81 * 150) or 12,150 microorganisms.

Determine whether the relation is a function.<br><br> (4,0), (4,1), (5,2), (6,3), (6,4)

Alexxandr [17]

Answer:

The relation is not a function.

Step-by-step explanation:

In order for a relation to be a function, there can only be one output for every x value. If you were to graph this equation, it would not pass the vertical line test, as 4 has two outputs (0 and 1) and 6 has two outputs (6 and 4).

The function, f(n) = 70n – 400, models the profit of the instructor of a guitar class per month, where n is

aleksandr82 [10.1K]

Atleast 6 students must be enrolled to make a profit and 20 student are needed to make $1,000.00 profit per month.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the function:

f(n) = 70n - 400

To make a profit, f(n) > 0, hence:

70n - 400 > 0

n > 6

For a profit of $1000:

70n - 400 = 1000

n= 20

Atleast 6 students must be enrolled to make a profit and 20 student are needed to make $1,000.00 profit per month.

The lengths of the sides of a triangle are in ratio 5 : 7 : 9. The middle-in-length side is 35 cm. Find the perimeter of the tri

ipn [44]

Answer:

The perimeter of the triangle is 105 cm.

Step-by-step explanation:

The ratio of sides of a triangle is $5:7:9$ .

The length of middle side is 35 cm.

Let first side of the tringle is $x$ , length of third side is $y$ . middle side is of 35 cm.

So, the ratio of length of sides can be written as,

$x:35:y=5:7:9$

Compare the ratio to get the value of $x$ and $y$ .

$x:35:y=25:35:45\\x=25\\y=45$

Now, the sides of the triangle are 25 cm, 35 cm and 45 cm.

Thus, the perimeter of the triangle will be the sum of all sides and can be calculated as,

$p=25+35+45\\p=105$

Therefore, the perimeter of the triangle is 105 cm.
