Answer:

21.3576443

Step-by-step explanation:

Trig rules state that csc = hypotenuse / opposite.

The opposite side to the given angle measures 11 units. The given angle measures 31 degrees. We need to find the length of the hypotenuse.

Therefore, we write,

x/11 = csc(31)

x = csc(31) * 11

x = 21.3576443

Hope this helps!

Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis. y = 64x−8x^2,
Mandarinka [93]
We need to get the limits first. When y = 0
0 = 64x - 8x^2
x = 0 and x = 8
The volume is
V = ∫ y dx from 0 to 8
V = ∫ (64x - 8x^2) dx from 0 to 8
V = 32x^2 - 8x^3/3 from 0 to 8
V = 682.67<span />

Area of paralellogram with base 15cm and height12cm
azamat

Answer:

180 cm2

Area of a polyhedron:

15(=base)x12(=height)

=180cm2

btw parallelogram is a 2D pic how you can come out a ''base'' and ''height''? It should be called a polyhedron. Your question is weird.

If so, your ''area of parallelogram'' is 15cm2 since your question is hecking  weird.

Btw it's 15cm2 not 15

At an electronic store, 4 phones and 3 laptops together cost $1580.62. The total cost of 2 laptops and 5 cameras is $1340.90. If
Mashutka [201]

Answer:

$2,677.72

Step-by-step explanation:

L = 3C

P

4P + 3L = 1,580.62

2L + 5C = 1,340.90

4P + 5L + 3C = ?

2L + 5C = 1,340.90

6C + 5C = 1,340.90

11C = 1,340.90

C = 121.90

121.90 * 3 = 365.70

L = 365.70

4P + 3L = 1,580.62

365.70 * 3 = 1,097.10

4P = 483.52

P = 120.88

C = 121.90

L = 365.70

P = 120.88

4P + 5L + 3C = ?

4(120.88) + 5(365.70) + 3(121.90) = 2,677.72
