An ice cream shop sells cones at the volume of 94.2 cubic meters they want to double the volume of the cones without changing th
marin [14]
The volume of a cone is V=\pi r^2\frac{h}3 where r = radius and h = height. If the cone has a volume of 94.2 cm³ (I assume you didn't mean m³ because that would be ridiculously huge) and a height of 10 cm, we can plug these values into the formula to find the radius. Don't do any rounding.

94.2 = \pi r^2\frac{10}3 \\ 282.6 = \pi r^2 *10 \\ 28.26 = \pi r^2 \\ 8.99543738355 = r^2 \\ 2.99923946752=r

Now we know that's going to be the radius of our <em>new </em>cone as well since we're keeping the diameter the same. The volume is going to be double 94.2 which is 188.4. Let's solve for the height.

188.4 = \pi (2.99923946752)^2\frac{h}3 \\ 188.4 = \pi(8.99543738355)\frac{h}3 \\ 188.4 = 28.26\frac{h}3 \\ 565.2 = 28.26h \\\\ \boxed{h = 20, r\approx 3}

The profit a business earns by selling aa items is given by the polynomial function: p(x) =x(160 − x) − (100x +500). What is the
HACTEHA [7]

Answer:

The last rem of the polynomial is -500          

Step-by-step explanation:

We have given that the profit a business earn by selling items is given by polynomial p(x)=x(160-x)-(100x+500)

We have to find the last term of the polynomial when it is written in standard form

For writing in standard form first we have to do operation on the polynomial

So p(x)=x(160-x)-(100x+500)=160x-x^2-100x-500=-x^2+60x-500

So the last rem of the polynomial is -500
