Mandarinka [93]

Answer:

a) e-0.03x(0.3-0.009x)

b) 33 hrs 20 min

c) 17.182

Step-by-step explanation:

Taking derivative of the above equation would give us the rate for change in donations :

hence

f'(x) = d/dx (0.3xe-0.03x)

using product rule of derivation where (uv)' = u'v +v'u

hence

f'(x) = (e-0.03x)d/dx(0.3x) + 0.3x*d/dx(e-0.03x)

       = 0.3e-0.03x + 0.3x(-0.03)(e-0.03x)

  f'(x)   =0.3e-0.03x -0.009xe-0.03x

hence

a) rate of change in donations = e-0.03x(0.3-0.009x) taking exponent common

b) f'(x) = 0 according to statement

hence 0 = e-0.03x(0.3-0.009x)

     0 = 0.3 - 0.009 x

which gives x = 33.33 hrs i.e after 33 hrs and 20 minutes rate of change of donations is 0.

c) donation level at the time is given by

f(x) = 0.3xe-0.03x

f(33.33) = 0.3 (33.33)e-0.03(33.33)

              = 17.182

That is 17.182 thousand donations were made at that time.

i used the answer key to get my answer and checked it with my dumb useless teacher and it’s right but, he won’t tell me how to g

You multiply it with the same number you use for the denominator.
in this case 3/4 and 7/10
you find the LCM of the denominator is 20
so for 4 to become 20 you multiply by 5 then for the numerator 3 also multiply by 5, so you get 15/20
its the same also with 7/10, you multiply both the numerator and the denominator by 2 and get 14/20
hope it help... :)

The barbecue started at half-past 5.
bezimeni [28]

Answer:

7:30

Step-by-step explanation:

Half past 5 would be 5:30.

An hour is 60 minutes, half of 60 is 30

In order to find the time two hours later we must add 2 to 5:30

5:30+2=7:30

Sofia surveyed students at her school
IRISSAK [1]

Answer:

English,French,Vietnamese,Chinese,Ukrainian,other

Step-by-step explanation:

so basically the question is asking for us to convert the fractions into decimals and then, order the them from greatest to least

Q:how do you convert a fraction into a decimal?

A: numerator divided by denominator for example if you had to convert 7/9 into a decimal you would do 7 divided by 9!!!

English:1/4 is equivalent to 0.25

Ukrainian:1/20 is equivalent to 0.05

Vietnamese:0.02 is already in decimal form

French:1/10 is equivalent to 0.1

Chinese:0.02 is already in decimal form

Other:0.06 is already in decimal form

<em>Now we got all the fractions converted into decimals</em>

0.25,0.05,0.02,0.1,0.02,0.06

Now we have to put these number from greatest to least

Q:how do we put it in greatest to least?

A: if there are more zeros in the place value its more likely to be a small number for example 0.06 is smaller than 0.3

0.25 is the greatest

0.1 is the second greatest

0.02 is the third greatest

0.02 is the third greatest

0.05 is the 4th greatest

0.06 is the 5th greatest

Now we got them from greatest to least so we match the decimal numbers to the language

Starting from greatest to least is: English,French,Vietnamese,Chinese,Ukrainian,other
