The average value of f(x) over [2, 6] is given by the definite integral,
![\displaystyle f_{\rm ave[2,6]} = \frac1{6-2} \int_2^6 3\ln(2+x^3)\cos(x) \, dx](https://tex.z-dn.net/?f=%5Cdisplaystyle%20f_%7B%5Crm%20ave%5B2%2C6%5D%7D%20%3D%20%5Cfrac1%7B6-2%7D%20%5Cint_2%5E6%203%5Cln%282%2Bx%5E3%29%5Ccos%28x%29%20%5C%2C%20dx)
and is approximately -1.67284.
40/10=4
50/10=5
60/10=6
the triangle of the drawing has sides of 4 inch 5 inch and 6 inch
Quantity is the amount of something you have. Quality is whether the product is good or long-lasting
Answer:
-10n - 60
Step-by-step explanation:
Use the distributive property to simplify [ a(b + c) = ab + ac ]
-10(n + 6)
(-10 * n) + (-10 * 6)
-10n + -60
-10n - 60
Best of Luck!
Answer:

Step-by-step explanation:
we are given half-life of PO-210 and the initial mass
we want to figure out the remaining mass <u>after</u><u> </u><u>4</u><u>2</u><u>0</u><u> </u><u>days</u><u> </u>
in order to solve so we can consider the half-life formula given by

where:
- f(t) is the remaining quantity of a substance after time t has elapsed.
- a is the initial quantity of this substance.
- T is the half-life
since it halves every 140 days our T is 140 and t is 420. as the initial mass of the sample is 5 our a is 5
thus substitute:

reduce fraction:

By using calculator we acquire:

hence, the remaining sample after 420 days is 0.625 kg
