How do you express 68,070,000,000,000 in Scientific Notation?

Answers

Answer 1

Answer: so since scientific notation is
(a number more than 1 and less than 10) times 10^x

move the decimal place to the left and count the places until the decimal is between the 6 and the 8
the number is 13
6.807 times 10^13 or
6.807e+13

Answer 2

Answer: 6,807 times 10 to the power of 10

Step-by-step explanation:

Moving Company A charges a flat fee of $1200 plus $18 and hour. Company B charges $900 plus $23 an hour. After how many hours would the price be the same regard-less of which company was chosen?

Answers

We need to create two expressions, then equate them in order to find the numbers of hours.

Let X = Number of hours

Let 1200+18x = Company A (Flat Fee + Hourly Rate*Hours)

Let 900+23x = Company B

$1200+18x=900+23x\n300+18x=23x\n300=5x\n60=x$

After 60 hours, the prices will be the same

Answer with explanation:

$7x^3+8$

we first cube a number x i.e. $x^3$

and then multiply it by 7 and then finally add 8 to the resulting expression.

$(7x+8)^3$

We first multiply the number x by 7 and then add 8 to it and then cube the resulting expression.

$(7x)^3+8$

We first multiply x by 7 to get 7x and then cube the number and finally add 8 to it.

$7(x+8)^3$

We add 8 to a number x to get x+8 and then cube it and finally multiply 7 to the resulting expression.

(7x)3+8 8 added to the cube of 7x

(7x+8)3 The cube of the sum of 7x and 8

7(x+8)3 7 times the cube of the sum of x and 8

7x3+8 8 added to 7 and x cubed

Write a quadratic equation whose roots are 1+8i and 1-8i

Answers

If 1+8i and 1-8i are the equation's roots, then the quadratic equation is

x² - 2x + 65 = 0.

What is meant by Quadratic equation?

A quadratic equation is written in standard form as y = ax² + bx + c, where a, b, and c are simple numbers. A quadratic equation's factored form is denoted by the expression y = (ax + c) (bx + d), where a, b, c, and d are simple numbers.

Any quadratic problem can be solved using the quadratic formula. The equation is first changed to have the form ax² + bx + c = 0, where a, b, and c are coefficients. After that, we enter these coefficients into the following formula: (-b ± √(b² - 4ac)) / (2a).

If 1+8i and 1-8i are the equation's roots, then:

x - (1 + 8i) = 0 and x - (1 - 8i) = 0 then we get

x - 1 - 8i = 0 and x - 1 + 8i = 0

⇒ (x - 1 - 8i)(x - 1 + 8i) = 0

⇒ x² - x + 8ix - x + 1 - 8i - 8ix + 8i + 64 = 0

⇒ x² - 2x + 65 = 0

The quadratic equation is x² - 2x + 65 = 0.
