Answer:

H: 41

Step-by-step explanation:

upfront charge = 36

each cone costs .52

sell price 1.40

(sell price - cone cost) * number of cones - upfront cost =0 to find where break even is

-36+(1.40-.52)*x=0

-36+.88x=0

.88x=36

x=40.90

need to round up to break even to 41

8x + 58 > 500 what is this?

IgorC [24]

Answer:

$8x + 58 > 500 \\ 8x > 500 - 58 \\ 8x > 442 \\ x > \frac{442}{8} \\ \boxed{x > 55.25}$

<h3><u>x>55.25</u> is the right answer.</h3>

Find, correct to four decimal places, the length of the curve of intersection of the cylinder 16x2 + y2 = 16 and the plane x + y

lubasha [3.4K]

First find a parameterization for the curve of intersection.

Given the equation of a cylinder, a natural choice for a parameterization would be one utilizing cylindrical coordinates. Here,

$16x^2+y^2=16\implies x^2+\left(\dfrac y4\right)^2=1$

which suggests we could use

$\begin{cases}x(t)=\cos t\\y(t)=4\sin t\\z(t)\end{cases}$

with $0\le t\le2\pi$ , and we get $z(t)$ from the equation of the plane,

$x+y+z=12\implies z(t)=12-x(t)-y(t)=12-\cos t-4\sin t$

Now use the arc length formula:

$\displaystyle\ell=\int_0^{2\pi}\sqrt{\left(\dfrac{\mathrm dx}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dy}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dz}{\mathrm dt}\right)^2}\,\mathrm dt$

$\displaystyle\ell=\int_0^{2\pi}\sqrt{\sin^2t+16\cos^2t+(\sin t-4\cos t)^2}\,\mathrm dt$

$\displaystyle\ell=\sqrt2\int_0^{2\pi}\sqrt{\sin^2t-4\cos t\sin t+16\cos^2t}\,\mathrm dt\approx\boxed{24.0878}$

Bart cuts a rectangular prism with a parallel to the base of the prism. What will the shape of the cross section be?

Liono4ka [1.6K]

Answer:

The resulting cross section is a rectangle. SOLUTION: A plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. So the cross section is a triangle.
