Point-slope form : y - y1 = m(x - x1)

slope(m) = 3
(4,2)...x1 = 4 and y1 = 2
now we sub

y - 2 = 3(x - 4) <===

Hi,

Formula for ball volume (considered a sphera) is:

$V=\dfrac{4\pi\cdot r^3}3=\dfrac{4\pi\cdot 15^3}3=\dfrac{42,390}3=14,130\ in^3.$

Cody, the owner of an e-commerce site, buys emerald pendants for $400 and then sells them

Trava [24]

Answer:

The marked up percentage is 112.5%

Step-by-step explanation:

The cost price of the emerald pendant = $400

The selling price of the emerald pendant = $840

Now, the Mark up Price = Selling Price - Cost Price

= $840 - $400 = $450

Also, $\textrm{Percentage of Mark up Price} = \frac{\textrm{the Marked up price}}{\textrm{The Cost Price}} \times 100$

= $\frac{450}{400} \times 100 = 112.5$

⇒ Percentage of Mark up Price = 112.5%

Hence, the marked up percentage is 112.5%

Give the parallel cross-section for the following: Cylinder, cone, sphere, and pyramid.

Maurinko [17]

The parallel cross-sections of a cylinder, cone, sphere, and pyramid are a circle, a circle, a circle, and a square.

We are given some solids. Solid geometry, or stereometry, is the traditional name for the geometry of three-dimensional Euclidean spaces in mathematics. Stereometry is concerned with measuring the volumes of various solid figures. The given solids are a cylinder, cone, sphere, and pyramid. We need to find the parallel cross-sections of the given solids. Parallel cross sections are cross sections of a solid that are parallel to each other. A cross section is a straight slice of an object. The parallel cross-sections of a cylinder, cone, sphere, and pyramid are a circle, a circle, a circle, and a square.
