Answer:

30 to 48, 40/64

Step-by-step explanation:

Which ratios are equivalent to 10:16, and they gave us 30 to 48, 25:35, 40/64, 8/32 and 5 to 15.

For 30 to 48, we can mulitply the 10:16 by 3 to give us 30:48, so it is <u>equal</u>.

For 25:35, we simplify it to 5:7, while 10:16 is 5:8, so they are <u>not equal</u>.

For 40/64, we can take 10:16 and multiply them by 4, getting the same number. Therefore, it is <u>equal</u>.

For 8/32, we can simplify it down to 1/4, while 10:16 simplifies down to 5:8, it is  <u>not equal</u>.

Lastly, for 5 to 15, w can simplify that to 1/3, and get 5:8 for 10:16, so it <u>won't be equal.</u>

Remark

There are occasions where this is very handy to know. Use FOIL.

Solve

F: (First): x*y = xy

O: (Outside): x *(-9) = - 9x

I:(Inside): (-7)*y = - 7y

L:(Last): (-7)*(-9) = 63

Add the terms together

xy - 9x - 7y + 63   <<<< Answer

. City workers recorded the number of squirrels in a park over a period of time. At the first count, there were 15 pairs
coldgirl [10]

Answer:

Exponential

P(X) = P_0 (2)^{2x}

Step-by-step explanation:

Given that at the first count, there were 15 pairs

of male and female squirrels (30 squirrels total). After 6 months, the city workers recorded a total of 60 squirrels,

and after a year, there were 120.

i.e. every 6 months population of squirrel is doubling.

a) Function is exponential since every time of 6 months population is doubled

b) The function that represents the population of squirrels recorded over x number of years.

We know that every 1/2 year it doubles.  Hence initially if P0 is started with in 1/2 year it would be 2P0 and in 1 year it would be 4P0 and so on.

In other words, the model would be

P(X) = P_0 (2)^{2x} where x = no of years
