Yes, when b is 0 on the equation y = mx + b (b = the y-axis) then that only means when you graph it, the starting point is on the origin (0,0).

To find the height, you would first multiply the length and width. You would get 56. Set that equal to 280 with an x to represent height. 280=56x. Then, you would divide 56 on both sides which leaves you with 5=x. So, your height would be 5 meters.

vredina [299]

By the law of sines,

$\dfrac{\sin90^\circ}{17}=\dfrac{\sin y^\circ}9$

$\implies\sin y^\circ=\dfrac9{17}$

(since $\sin90^\circ=1$ )

$\implies y=\sin^{-1}\left(\dfrac9{17}\right)\approx32.0$

The radius of the large sphere is double the radius of the

Aleonysh [2.5K]

Answer:

8 times

Step-by-step explanation:

We know that the radius of smaller sphere is r,

The volume of sphere is given by:

$V_1=\frac{4}{3} \pi r^{3}$

where V_1 is the volume of the small sphere.

As we know that the radius of large sphere is double of the smaller sphere, the radius of large sphere will be 2r

Let V_2 be the volume of large sphere

$V_2=\frac{4}{3}\pi (2r)^{3} \\ =\frac{4}{3}\pi *8r^3$

Separating 8 aside

$V_2=8(\frac{4}{3}\pi r^{3})\\V_2=8V_1$

We can see that the volume of large sphere is eight times the volume of small sphere ..
