makvit [3.9K]

Answer:

148 square inches

Step-by-step explanation:

Step 1: finding the area of the base (upper base plus lower base)

        2( L x W).                  

      2 (6in. x 5in.)

      2( 30 square inches.)

      60 square inches

Step 2: finding the area of first 2 sides

     2 ( l x w)

   2 ( 5in x 4in)

  2 ( 20 square inches.)

     40 square inches

step 3: finding the area of the last 2 sides

  2(lxw)

  2(4in.x 6in.)

 2(24 square inches.)

  48 square inches

step 4: combine all the answers.

60 square inches. + 40 square inches. + 48 square inches = 148 square inches

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)
