Kareem heats a beaker of water to boil. Then he records that the water temperature decreases from 100% C to 19 C in 5 2/5 minutes. What was the charged in temperature each minute?

Given :

Kareem heats a beaker of water to boil. Then he records that the water temperature decreases from 100° C to 19° C in 5 2/5 minutes.

To Find :

What was the charged in temperature each minute.

Solution :

Time taken to reach 19° C :

Now, change in temperature per minute is given by :

Therefore, the charged in temperature each minute is -15 °C/minute .

Hence, this is the required solution.

idk but i found this "the graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.  

so, since the point (9,2) lies on the graph of y = f(x), the point (11,2) lies on the graph of y = f(x-2)."

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
