Answer:

896

Step-by-step explanation:

Cube:

8 x 8 = 64

64 x 13 = 832

Pyramid:

8 x 8 = 64

64 x 3 = 192

192 / 3 = 64

_____________________

Cube + Pyramid:

832 + 64 = 896

in a right triangle, the 58cm hypotenuse makes a 51 angle with one of the legs. rounded to two decimals places, how long is that
ser-zykov [4K]

Answer:

36.50

To two decimal places

Step-by-step explanation:

The hypothenuse side in a right angle triangle has 58cm. While the angle touching one of its leg is 51°. How long is that leg.

From the right angled triangle, the size of the leg touching the hypothenuse is the adjacent side of the triangle, hence in trigonometry, the cosine rule is used, because it involves the adjacent and the hypotenuse.

Cos 51°=x/58

Let the size of the leg be x

Making x the subject

x=58(Cos51°)

x=36.500058

Correct to two decimal place

x=36.50

Find (a) the amplitude, (b) the wavelength, (c) the period, and (d) the speed of a wave whose displacement is given by y= 1.5 co
leonid [27]

Answer with Step-by-step explanation:

We are given that displacement of wave

y=1.5cos(0.68x+37t)

Where y in cm  and t in sec.

a.Compare it with

y=Acos(kx+\omega t)

Amplitude of wave=A

We get A=1.5

Amplitude=A=1.5  cm

b.k=0.68

\frac{2\pi}{\lambda}=0.68

\lambda=\frac{2\times 3.14}{0.68}=9.2 cm

Using \pi=3.14

Wavelength of the wave=9.2 cm

c.Period=\frac{2\pi}{T}=\omega

\frac{2\pi}{T}=37

T=\frac{2\times 3.14}{37}=0.17 s

The period of the wave=0.17 s

Speed of the wave=\nu \lambda=\frac{\lambda}{T}=\frac{9.2}{0.17}

Speed of the wave=54.1 cm/s
