Answer:

Option 3 -  1.3E-2=0.013

option 4 -   1.3E-2=1.3\times 10^{-2}

Step-by-step explanation:

Given : Kory calculated several numbers in his calculator. The result displayed 1.3E-2 on the calculator screen.

To find : Which equivalent number(s) does this represent?

Solution :

The result displayed 1.3E-2 on the calculator screen is written in scientific notation where E represents 10 to the power.

So, We can write 1.3E-2 in standard notation,

1.3E-2=1.3\times 10^{-2}

or 1.3E-2=\frac{13}{10}\times \frac{1}{100}

1.3E-2=0.013

Therefore, Option 3 and 4 are equivalent.

Answer:

  • 0.013
  • 1.3×10^(-2)

Step-by-step explanation:

Many calculators use "E" to signify "×10^( )". Thus ...

... 1.3E-2 = 1.3×10^(-2)

This number in scientific notation is equivalent to the standard form number ...

... 1.3×0.01 = 0.013

Find a positive number for which the sum of it and its reciprocal is the smallest​ (least) possible. Let x be the number and let
Allisa [31]

Answer:

S(x) = x + \frac{1}{x} --- Objective function

Interval = \{x:x=1\}

Step-by-step explanation:

Given

Represent the number with x

The required sum can be represented as:

x + \frac{1}{x}

Hence, the objective function is:

S(x) = x + \frac{1}{x}

To get the the interval, we start by differentiating w.r.t x

<em>Using first principle, this gives:</em>

S'(x) = 1 - \frac{1}{x^2}

Equate S'(x) to 0 in order to solve for x

0 = 1 - \frac{1}{x^2}

Subtract 1 from both sides

0 -1 = 1 -1 - \frac{1}{x^2}

-1 = - \frac{1}{x^2}

Multiply both sides by -1

1 = \frac{1}{x^2}

Cross Multiply

x^2 * 1 = 1

x^2  = 1

Take positive square root of both sides because x is positive

\sqrt{x^2} = \sqrt{1

x = 1

Representing x using interval notation, we have

Interval = \{x:x=1\}

To get the smallest sum, we substitute 1 for x in S(x) = x + \frac{1}{x}

S(1) = 1 + \frac{1}{1}

S(1) = 1 + 1

S(1) = 2

<em>Hence, the smallest sum is 2</em>

Question 8 is the one I’m having trouble on it
salantis [7]
Just multiply 30 times 2,000 and also multiply 30 times 700. The reason you will multiply it by 30 is because in 1 month there is 30 days. 30 x 2,000= 60000 30 x 700 = 21000 I’m only 9 btw so sorry if I didn’t give a lot of detail lol
