Answer: 10
Step-by-step explanation:
Since integral from 1 to 4 of f(x) =10
To evaluate integral from 2 to 8 of 2 times f(2x), using substitution method
Let U = 2x, dU = 2dx, dx = dU/2
Evaluate the limit, upper limit gives dU = 2*4 = 8, lower limit gives dU = 2*1 = 2.
Since this limit are the same as the limit for the question,
Therefore, F(4) - F(1) = F(8) - F(2) = 10
Substituting dx=dU/2
Gives,
Integral from 2 to 8 of 2 times f(2x)= (1/2)(2)(F(8)-F(2)) = 10

Answer:
78.54 rounded to the tenths it is 78.5
Step-by-step explanation:
I did the math. And I did my work like this
5*5=25
25*pi=78.5398163
Rounded to hundredths 78.54
Rounded to tenths 78.5 Hope this helps, let me know if correct, and have a great day!!
Answer:
300-20x<100
Step-by-step explanation:
More than, is like greater than, making it a greater than sign,
$100 is the number that is being compared to the other two, so it goes on the other side
$300 is the inital price, so it has no variable
Last, the $20 represents the cost per shirt giving it an unknown variable
I hope this helps u
pls give a brainliest and a thx ;)
Answer:
sqrt(20)
Step-by-step explanation:
The two perpendicular side lengths are equal, so using Pythagoras theorem:
x = sqrt( sqrt(10)^2 + sqrt(10)^2 )
x = sqrt(10 + 10)
x = sqrt(20)
