Besides math name a reason why someone would need to find the volume of a cone, and a prism?

storchak [24]

Answer:

The volume of a cone is given by the equation:

$V=\frac{1}{3}\pi r^2 h$

where

r is the radius of the cone

h is its height

We have several examples of cones in real life: for instance, the cone of an ice-cream, it has a conic shape.

The volume of a prism instead is given by:

$V=lwh$

where:

l is the length of the base

w is the width of the base

h is the height of the prism

Again, we have several examples of prisms in daily life: for example, boxes have usually the form of a prism, so it can be useful to know their size in order to calculate their volume.

To approach the runway, a pilot of a small plane must begin a 10 degrees descent starting from a height of 1983 feet above the g

ddd [48]

<h3>Answer:</h3>

2.2 miles

<h3>Explanation:</h3>

The mnemonic SOH CAH TOA reminds you that

... Sin = Opposite/Hypotenuse

We are given an angle (10°) and its opposite side length (1983 ft), and we are asked to find the hypotenuse (the straight-line distance from the plane to the runway).

... sin(10°) = (1983 ft)/distance

Multiplying by distance and dividing by sin(10°), we have ...

... distance = (1983 ft)/sin(10°) ≈ 11419.6 ft

We want to express this in miles, so we have ...

... 11419.6 ft = (m mi)×(5280 ft/mi)

... (11419.6 ft)/(5280 ft/mi) = m mi ≈ 2.163 mi

Rounding to tenths, the distance is ...

2.2 miles

_____

<em>Comment on the question</em>

The distance from the plane to the airport is different than the horizontal distance from the airport at which the descent must start. The latter distance is the "adjacent" leg of the triangle, so must be found using the tangent function. Rounded to tenths, it is 2.1 miles.

Identify the relative maximum value of g(x) for the function shown below g(x)=7/x^2+5

Liula [17]

To find t<span>he relative maximum value of the function we need to find where the function has its first derivative equal to 0.

Its first derivative is -7*(2x)/(x^2+5)^2
</span>7*(2x)/(x^2+5)^2 =0 the numerator needs to be eqaul to 0
2x=0
x=0

g(0) = 7/5

The <span>relative maximum value is at the point (0, 7/5).</span>
