A block of wood has a mass of 120g and a volume of 200cm3. What is the density of the wood?

ozzi

Density=mass/volume
given mass=120g and volume=200cm3
density= $\frac{120g}{200cm^3}=\frac{3}{5} \space\ \frac{g}{cm^3}$ or abot 0.6

the density is $0.6 \space\ \frac{g}{cm^3}$

The radius of a circle is 8 inches. What is the angle of an arc 2π inches long?

Y_Kistochka [10]

Answer:

π/4 radians

Step-by-step explanation:

The arc length formula is s = rФ, where Ф is the central angle (in radians).

Here, r = 8 inches and s = arc length = 2π inches. We need to find the central angle, Ф. The formula given above is s = rФ, or, equivalently,

Ф = s/r.

Here, the central angle is Ф = s/r = 2π/8, or π/4 radians.

Janet is drawing the path formed by the parametric equations x=2+3 sin t and y=1-1/2cos t. Which curve did she draw??

frosja888 [35]

Sin²t +cos²t =1

<span> x=2+3 sin t
sin t=(x-2)/3

</span><span>y=1-1/2cos t
y-1= - (cos t)/2
cos t =-(y-1)/(1/2)

</span>(x-2)²/3² + (y-1)²/(1/2)² = 1
