Answer:

1.) 7.86 × 10^-7

2.) 3.94 × 10^3

3.) 4.7 × 10^0

4.) 1.26 × 10^6

5.) 6.0 × 10^-2

6.) 1.75 × 10^2

<u>What is 0.06 in scientific notation?</u>

6.0 × 10^-2

Step-by-step explanation:

(Explanation for 0.06)

------------------------------------------------------------------------------------------------------------

1.) <u>Create Initial Equation </u>

First, create an equation with the initial decimal being the coefficient multiplied by 10 to the power of 0.

(For example, let’s create the starting scientific notation equation for the decimal 475,000).

475,000 = 475,000 × 10^0

------------------------------------------------------------------------------------------------------------

2.) <u>Move the Decimal Point</u>

Now that we have an equation, the second step is to move the decimal point in the coefficient until there is 1 significant digit to the left of the decimal point. For each space the decimal point is moved to the left, increase the exponent by 1.

(Continuing the example above, move the decimal point to the left and increment the exponent.)

475,000 = 475,000.0 × 10^0

475,000 = 47,500.0 × 10^1

475,000 = 4,750.0 × 10^2

475,000 = 475.0 × 10^3

475,000 = 47.5 × 10^4

475,000 = 4.75 × 10^5

2) 16 + -7<br><br> Step by step please
gregori [183]

Answer:

9

Step-by-step explanation:

The rules that you need to know for this question are:

- & - = +

+ & - = -

+ & + = +

So for this question we have 16 + -7 so we need to use the + & - rule. Therefore a plus and a minus make a minus so we do 16-7 which is 9

Volgvan
If you take a look at my really poorly drawn diagram, we can see it is a trigonometry problem. The angle, however, is outside the triangle, and we can find the angle inside the triangle next to it by taking it away from 90°:
90°0' - 72°54' = 17°6' ≈ 17.1°.
We can find the other angles becuase one is 90° and the other is:
180°-90°-17°6'=72°54' ≈ 72.9°(which you can see if you know your angle theorems).

We now have diagram 2, nicely simplified so we can see where to go.
Using the Sine Rule, i.e.
\frac{sin(A)}{a} = \frac{sin(B)}{b}
We can rearrange to find our length b:
b=a \frac{sinB}{sinA}
Substituting numbers in:
b=1191 \frac{sin(17.1)}{sin(72.9)} =366.399...ft
b=366 feet.
