What is 3.25 x 10^4 as an ordinary number?

Mathematics

Veronika [31]3 years ago

The 10 followed by the little superscript number just represents how many decimal places you move to get your final number. So:

3.25 × 10⁴ just means you move the decimal point (between 3 and 2) four times to the right: 32500 (the decimal point would be after the last 0, so technically it's 32500.0, but you don't need to write that).

When the little superscript number is negative, you move the decimal point to the left:

6.04 × 10⁻³ = 0.00604 (make sure to add a zero before the decimal too).

When you write a standard form number, you have to make sure the number is larger than 0 and less than 10, so converting a number like 2,400,000 would be 2.4 × 10⁵, because you're moving the decimal place 5 times to get 2,400,000.

0.00147 is 1.47 × 10⁻³ because once again, you have to move 3 decimal places to the left.

Let the graph of g be a translation 5 units up followed by a reflection about the y−axis of the graph of f(x)=6x. Write a rule f
yan [13]

Reflections and translations are instances of transformation.

<em>The rule of function g for the given reflection and translation is </em>g(x) =-6x + 5<em />

<em />

Given

f(x) = 6x

<u>The rule of translating 5 units up is:</u>

(x,y) \to (x,y+5)

So, we have:

f'(x) = f(x) +5

f'(x) = 6x +5

<u>The rule of reflecting about the y-axis is:</u>

(x,y) \to (-x,y)

So, we have:

g(x) =f(-x)

g(x) =6(-x) + 5

g(x) =-6x + 5

Hence, the rule of function g is: g(x) =-6x + 5

I don’t understand this can someone please give me and example on how to do it please?

For the first one,

you multiply 5x and -5 to get -25.

Then you move the constant to the right and change the sign to get 3x= -21 +25.

Calculate the sum of -21+25 to get 4.

Divide both sides of the equation by 3 to get x=4/3.

So then your final answer is x=4
——
3


For the second one,

Distribute 7 through the parentheses to get 14x + 14+8=120

The you add 14+8 to get 22. Your equation should be 14x+22=120

Move the constant to the right side and change its sign to get 14x=120-22

Subtract 120-22 to get 98. Now your equation should be 14x=98

Divide both sides of the equation by 14 to get x=7.

Your finial answer for the second one should be x=7.
