Answer: 4.3 * 10^-9 or 4.3 * 0.000000001

Reasoning:

PART 1

Expressing numbers as a digit times a power of 10 can also be referred to as expressing them in scientific notation. When expressing numbers in scientific notation, the digit that is multiplied by the power of 10 must be no less than 1 and no greater than 10.

So, 0.0000000043 becomes 4.3.

PART 2

To get the power of 10 that you’ll multiply 4.3 by to get 0.0000000043, you can count the decimal places that the decimal point on 4.3 has to move to the left to become 0.0000000043.

You get 9 decimal places.

This will be the exponent on the 10 (the power of 10 you’ll have to multiply 4.3 by to get your desired product).

Because your original number is smaller than 1, your exponent becomes negative. So, your power of 10 is 10^-9 or 0.000000001.

When you combine the PART 1 & 2 responses, you get the final answer
4.3 * 10^-9 or 4.3 * 0.000000001.

Hope this helps!

Answer:

9 comedy

12 horror

Step-by-step explanation:

First, there are 360 degrees in a circle.

Comedy = 90 degrees

Action and romance = 90 degrees combined

Horror = 120 degree

Science fiction = 60 degrees

To find sci fi : 90 +90 +120 = 300 - 360 = 60 degrees

36 students took the survey.

1/4 × 36 = 9

Horror is 120 degrees out of 360 degrees or 1/3 of the circle.

1/3 × 36 = 12

Center: (10,-10)

This is the standard form equation \frac{(x - 10)^2}{100} + \frac{(y + 10)^2}{-100} = 1

What is the ellipse?

The equation for an ellipse is typically written as x² a²  + y² b² = 1. x²  a² + y² b²  = 1. An ellipse with its origin at the center is defined by this equation. The ellipse is stretched further in both the horizontal and vertical directions if a > b, a > b, and if b > a, b > a, respectively.

The standard form of the equation of an ellipse with center (h, k)and major axis parallel to the x-axis is:

\frac{(x - h)^2}{a^2} + \frac{(y - k)^2}{b^2} = 1

where,

a > b

the length of the major axis is 2a

the coordinates of the vertices are (h±a,k)

the length of the minor axis is 2b

the coordinates of the co-vertices are (h,k±b)

the coordinates of the foci are (h±c,k),

where c² = a² − b².

so,

\frac{(x - 10)^2}{100} + \frac{(y + 10)^2}{-100} = 1

Hence, this is the standard form equation \frac{(x - 10)^2}{100} + \frac{(y + 10)^2}{-100} = 1.
