Answer:

$9.7$ $x$ <em> </em> $10x^{-2}$

Step-by-step explanation:

Since $0.097$ is below $1$ , you would move the decimal right $2$ times.

That will get you to $9.7$ .

Since we moved it right two times, we get a number in between $10$ .

Scientific notation: $9.7$ $x$ $10^{-2}$ .

One number is 1 more than 2 times another. Their product is 10. Find the numbers.

Taya2010 [7]

Whenever a problem says "one number" and "another number" we can substitute x and y. for this we have x=2y+1 and xy=1. since we know the value of x (2y+1) we can substitute it for the other equation to get (2y+1)y=10. simplify to get 2y^2+y=10. from here you can do a few methods to solve this, but the simplest in my opinion is by factoring.

In order to factor it must be equal to 0, so we have 2y^2+y-10=0. We factor this and get y=5 (we also get y=-4 but it is an extraneous root). now we can plug that into either equation and find that x=2.

this means our two numbers are 5 and 2

The points (a,5) and (9,b) are on the circle x^2+ y^2= 125.

Aneli [31]

Answer:

a = 10

b = 6.633

Step-by-step explanation:

x²+ y²= 125.

In this equation, the value of x and y represent the coordinates of x and y respectively of point on which the circle passes.

x²+ y²= 125

a² + 5² = 125

a² + 25 = 125

a² = 125-25

a² = 100

a = √100 = 10

(9,b)

x²+ y²= 125

9² + b² = 125

b² 125 - 81

b² = 44

b = √44 = 6.633

A square of side length s lies in a plane perpendicular to a line L. One vertex of the square lies on L. As this square moves a

user100 [1]

Answer:

Part (A) The required volume of the column is $s^2h$ .

Part (B) The volume be $s^2h=\frac{s^2h}{2}+\frac{s^2h}{2}$ .

Step-by-step explanation:

Consider the provided information.

It is given that the we have a square with side length "s" lies in a plane perpendicular to a line L.

Also One vertex of the square lies on L.

Part (A)

Suppose there is a square piece of a paper which is attached with a wire through one corner. As you blow it up it spins around on the wire.

This square moves a distance h along L, and generate a corkscrew-like column with square.

The cross section will remain the same.

So the cross section area of original column and the cross section area of twisted column at each point will be the same.

The volume of the column is the area of square times the height.

This can be written as:

$s^2h$

Hence, the required volume of the column is $s^2h$ .

Part (B) What will the volume be if the square turns twice instead of once?

If the square turns twice instead of once then the volume will remains the same but divide the volume into two equal part.

$s^2h=\frac{s^2h}{2}+\frac{s^2h}{2}$

Hence, the volume be $s^2h=\frac{s^2h}{2}+\frac{s^2h}{2}$ .
