The equation for volume of a cylinder is :

V = PI x r^2 x h

Pi = 3.14

r = 1 ft

h = 4.5 ft

V = 3.14 x 1^2 x 4.5

V = 14.13 cubic feet.

Use the Pythagorean Theorem to determine how far the horizon line is from Felix when he is in the balloon.

neonofarm [45]

Answer:

Step-by-step explanation:

First, make sure all the units are the same. One is given in feet and the other is given in miles.

Let's convert everything to feet.

There are 5,280 feet in one mile.

So 3,959 times 5,280 is 2,090,3520

The horizon line will form a right angle so, the 2,090,3520 and the 127,851 can be used in the Pythagorean Theorem

2,090,3520^2 + 127,851^2

436,957,148,400,000 + 16,345,878,200

Then square root that answer to get

20,903,910.98 feet

The midpoint of AB is M(-5,1). If the coordinates of A are (-4,-5), what are the coordinates of B?

Elenna [48]

ANSWER:

The midpoint of AB is M(-5,1). The coordinates of B are (-6, 7)

SOLUTION:

Given, the midpoint of AB is M(-5,1).

The coordinates of A are (-4,-5),

We need to find the coordinates of B.

We know that, mid-point formula for two points A $(x_{1}, y_{1})$ and B $(x_{1}, y_{2})$ is given by

$M\left(x_{3}, y_{3}\right)=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)$

Here, in our problem, $\mathrm{x}_{3}=-5, \mathrm{y}_{3}=1, \mathrm{x}_{1}=-4 \text { and } \mathrm{y}_{1}=-5$

Now, on substituting values in midpoint formula, we get

$(-5,1)=\left(\frac{-4+x_{2}}{2}, \frac{-5+y_{2}}{2}\right)$

On comparing, with the formula,

$\frac{-4+x_{2}}{2}=-5 \text { and } \frac{-5+y_{2}}{2}=1$

$-4+\mathrm{x}_{2}=-10 \text { and }-5+\mathrm{y}_{2}=2$

$\mathrm{x}_{2}=-6 \text { and } \mathrm{y}_{2}=7$

Hence, the coordinates of b are (-6, 7).

WILL MARK BRAINLIEST !!! PLEASE find the length of PQ

mr_godi [17]

$\\ \rm\longmapsto L=\dfrac{\Theta}{180}\times \pi r$

$\\ \rm\longmapsto PQ=\dfrac{135}{180}\times 3.14(12)$

$\\ \rm\longmapsto PQ=\dfrac{3}{4}\times 37.68$

$\\ \rm\longmapsto PQ=\dfrac{113.04}{4}$

$\\ \rm\longmapsto PQ=28.3$

marta [7]

I hope this helps you

x= -2 h (-2)= 3. (-2)+1= -6+1= -5

x=-2 h (-2)= 3. (-2) -1= -6-1= -7
