Answer:

Solution : 126π/5

Step-by-step explanation:

Step 1 (Assign the 'values') : Using the cylinder method, given that x = 0 and x = 3, we will integrate along the x-axis from 0 to 3. The radius of each cylinder will be r = x, and the height should be the following,

h = y₁ - y₂ = x³ - 8

Step 2 (Substitute) : Remember that the volume of the graph will be in the following form,

\mathrm{V\:=\:2\pi \int _a^b\:rhdx}

If we substitute known values we should go in the following both. Remember that r = x, h = x³ - 8, b = 3, and a = 0 (our limits). Take a look at the attachment for those calculations. As you can see our solution is 126π/5.

If g(x) = 2x - 5 and h(x) = 3x + 7, then g(h(x)) = ?
lana [24]

Step-by-step explanation:

g(x) = 2x - 5

h(x) = 3x + 7

To determine g(h(x)), wherever you see an x in g(x), replace it with the equation h(x):

g(x) = 2x - 5

g(h(x)) = 2(h(x)) - 5

g(h(x)) = 2(3x + 7) - 5

g(h(x)) = 6x + 14 - 5

g(h(x)) = 6x + 9

A smaller square is within a larger square as shown below. A point is chosen at random in the larger square. What percent of the
Bas_tet [7]

Answer: 84.5%

Step-by-step explanation:

15.2 × 15.2 = 231.04 cm² (area of the entire large square)

5.98 × 5.98 = 35.76 cm² (area of the small square)

large square - small square = area of the blue region

231.04 - 35.76 = 195.28 cm² (area of the blue region)

\frac{area of the blue region}{large square} = percentage of time that the point will be in the blue region

\frac{195.28}{231.04} = 0.845 --> 84.5%

Evaluate the equation h - 3/5 = 13/45
blsea [12.9K]

Answer:

The choice A. h = 8/9

Step-by-step explanation:

h -  \frac{3}{5}  =  \frac{13}{45}  \\  \\ h =  \frac{13}{45}  +  \frac{3}{5}  \\  \\ h =  \frac{13}{45}  +  \frac{27}{45}  \\  \\ h =  \frac{40}{45}  =  \frac{8}{9}
