Answer: B. Cone

Step-by-step explanation:

In geometry, a solid cone is a three-dimensional shape that has a flat circular base, and a point called the apex or vertex such that it tapers from a circular base to a apex.

Therefore by the definition of cone , according to the given information if a image contains a circle and above a cone with 5 cm.

Then the figure created can be a cone.

The base of a solid in the region bounded by the two parabolas y2 = 8x and x2 = 8y. Cross sections of the solid perpendicular to

Usimov [2.4K]

The two curves intersect at two points, (0, 0) and (8, 8):

$x^2=8y\implies y=\dfrac{x^2}8$

$y^2=\dfrac{x^4}{64}=8x\implies\dfrac{x^4}{64}-8x=0\implies\dfrac{x(x-8)(x^2+8x+64)}{64}=0$

$\implies x=0,x=8\implies y=0,y=8$

The area of a semicircle with diameter $d$ is $\dfrac{\pi d^2}8$ . The diameter of each cross-section is determined by the vertical distance between the two curves for any given value of $x$ between 0 and 8. Over this interval, $y^2=8x\implies y=\sqrt{8x}$ and $\sqrt{8x}>\dfrac{x^2}8$ , so the volume of this solid is given by the integral

$\displaystyle\frac\pi8\int_0^8\left(\sqrt{8x}-\dfrac{x^2}8\right)^2\,\mathrm dx=\frac{288\pi}{35}$

Sarah has 2,500 pictures saved to her camera roll. She wants to free up some space on her phone. She will delete a total of 50 p

weeeeeb [17]

Answer:

x = number of days

y = number of remaining photos saved to her camera roll.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The number of pictures saved in the camera roll (2,500) minus the amount of photos that she deletes per day (50) multiplied by the number of days (x) must be equal to the number of photos remaining.

y =2,500- 50x

The variables are x and y.

Where x is the number of days and y is the number of remaining photos.
