Answer:

-21.5cm /\3

Step-by-step explanation:

To find the volume of a rectangular prism, you need to multiply length x width x height, which is 4 1/2 x 4 1/2 x 6 which equals 121 1/2. Then you subtract 121 1/2 by 143 which equals -21 1/2

The continuity of f' and its limiting behavior guarantees that f' is Riemann integrable, so you can write

\displaystyle\int_0^\infty f'(x)\,\mathrm dx=uv\bigg|_{x=0}^{x\to\infty}-\int_0^\infty v\,\mathrm du

where u=1\implies\mathrm du=0\,\mathrm dx and \mathrm dv=f'(x)\,\mathrm dx\implies v=f(x), so that

\displaystyle\int_0^\infty f'(x)\,\mathrm dx=f(x)\bigg|_{x=0}^{x\to\infty}=\lim_{x\to\infty}f(x)-f(0)=-f(0)

Please help me do question 21, 22 and 23. I am in 6th grade.
Pachacha [2.7K]

Question 21: 24 minutes

\frac{3}{\frac{3}{2} } = \frac{x}{12}

x = (\frac{3}{\frac{3}{2} })(12)

x = 24

Question 22: 20 centimeters

x = one side of the square

x² = 25

x = 5

4x = perimeter

4(5) = perimeter

20 = perimeter

Question 23: 17 sides

Hexagon = 6 sides

Octagon = 8 sides

Triangle = 3 sides

Total amount of sides = 6 + 8 + 3

Total amount of sides = 17
