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)

Factor the following quadratic.<br> y=2x^2 - 5x - 3
Reptile [31]

Answer:

(2x + 1)(x - 3)

Step-by-step explanation:

y = 2 {x}^{2}  - 5x - 3

2 {x}^{2}  - 5x - 3 = 0

(2x + 1)(x - 3)  = 0

x =  -  \frac{1}{2}

x = 3

Umnica [9.8K]

Answer:

Step-by-step explanation:

surface area of sphere=4πr²=4π×12²=576π

≈576×3.1416

≈1809.5616 cm²

cost to cover=1809.5616×0.05=$90.47808≈$90.48
