Notebooks are 10$ pencils are 6 markers are 7.5 add all together for 23.5 so then you’ll create two equal fractions 8.5/100 (the tax) and x/23.5 cross multiply 23.5 and 8.5 which is 199.75 and divide that by 100 which is 1.9975 which could round to 2 dollars which would be the tax and if you add two to 23.5 you’ll get 25.5 dollars which should be your answer but please correct me if i’m wrong

Use the value of the first integral I to evaluate the two given integrals. I = integral^3_0 (x^3 - 4x)dx = 9/4 A. integral^3_0 (

Troyanec [42]

Answer:

A) -9/2

B) 9/4

C) -9/2, same as A)

Step-by-step explanation:

We are given that $I=\int_0^3 x^3-4x dx=9/4$ . We use the properties of integrals to write the new integrals in terms of I.

A) $\int_0^3 8x-2x^3 dx=\int_0^3 -2(x^3-4x) dx=-2\int_0^3 x^3-4x dx=-2I=-9/2$ . We have used that ∫cf dx=c∫f dx.

B) $\int_3^0 4x - x^3 dx=-\int_0^3 (4x-x^3) dx=\int_0^3-(4x-x^3) dx=\int_0^3 x^3-4x dx=I=9/4$ . Here we used that reversing the limits of integration changes the sign of the integral.

C) It's the same integral in A)
