So what you do is convert these numbers to their original form so...
1.4 x 10^6 = 1,400,000
             and
3.2 x 10^4 = 32,000
Now multiply 1,400,000 and 32,000
=  44,800,000,000
Convert that into scientific notation.
Your answer is 4.48 x 10^10
I hope this helps love! :)

21. Glass Vase You are taking a glass-blowing class and have created a vase in the
WARRIOR [948]

Answer:

V = 12,348·π

Step-by-step explanation:

The given parameters of the glass Vase are;

The shape of the glass vase = A sphere

The radius of the vase, r = 21 inches

The given formula for finding the volume of a sphere is V = \dfrac{4}{3} \cdot \pi \cdot r^3

Therefore, when r = 21 inches, we get;

V = \dfrac{4}{3} \cdot \pi \cdot 21^3 = {12,348 \cdot \pi}

Therefore, the expression for finding the equation of the spherical glass vase, V = 12,348·π

Guys pls help me i have to write about angle on an A4 size paper
slamgirl [31]

Answer:

A tip for keeping the paper positioned at a 45 degree angle, until it becomes a habit, is to fold over the left hand lower corner of the paper for right-handed writers and the right hand for left-handed writers. The fold is then positioned so that it is parallel to the edge of the table closest to the child.

Where do I start with this? it is a calc question. I thought perhaps relating the height to the length to get everything in term
Oksanka [162]

Answer:

See below.

Step-by-step explanation:

You are correct in your approach. You can calculate the hypotenuse via Pythagoras, so you will know |AB|.

Then, I would do the following:

Denote the upper left corner of the rectangle that intersects with AB, a point D. Then call "a" the distance |AD|. Call the rectangle height x, and width y.

Use triangle similarity to set up a system of equations: A choice of "a" induces a rectangle x-by-y where

\frac{x}{a}=\frac{|BC|}{|AB|}\implies x = \frac{|BC|}{|AB|}\cdot a\\\frac{y}{|AB|-a}=\frac{|AC|}{|AB|}\implies y = \frac{|AC|}{|AB|}\cdot (|AB|-a)=|AC|-\frac{|AC|}{|AB|}\cdot a

Now, we can get 2*(x+y)  (aka, the perimeter) from those two equations:

2(x+y)=2(\frac{|BC|}{|AB|}\cdot a+|AC|-\frac{|AC|}{|AB|}\cdot a)=2a\frac{|BC|-|AC|}{|AB|}+2|AC|

which is a function of one variable "a" and you can  minimize that using a derivative.

But here's where I am finding this problem not a very good one: as you surely noticed the perimeter is <em>linear</em> in "a." As such, it's derivative will be constant and uninteresting. Even without the derivative you can see that to minimize the perimeter expression above, you should minimize "a."  In other words "a" should become infinitesimal and the rectangle will be basically (epsilon) by (|AC|-epsilon), where epsilon is as small as possible.

I imagine this problem would become only then "interesting" (in that a derivative would give you something), if the question was to minimize the <em>area </em>of the rectangle.

Please feel free to let me know if you have questions.
