What is 400,000 times 200 in scientific notation
aniked [119]

If you move the decimal point left until it is just to the right of the most-significant digit, the number of places you moved it is the power of ten that your new number is multiplied by.

400,000=4\times 10^{5}\\200=2\times 10^{2}

Then multiplication can proceed in the usual way, taking into account the rules of exponents.

4\cdot 10^{5}\times 2\cdot 10^{2}=8\cdot 10^{(5+2)}\\\\=8\cdot 10^{7}

Find the equation of line (use exact numbers)​
maw [93]

Answer:

y=3x+3

Step-by-step explanation:

Use the slope-intercept form:

y=mx+b

m is the slope and b is the y-intercept. The y-intercept is the place where x is equal to 0, and the slope is the change in the y-axis over the change in the x-axis, otherwise known as rise over run ( \frac{rise}{run} ).

If you study the graph, you can see that the line crosses the y-axis at (0,3), so 3 is the y-intercept. Insert into the formula:

y=mx+3

Now find the slope. Use the slope formula:

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}

You need two points first. You can use the y-intercept (0,3) and another even point, like (1,6). Insert the values:

(0_{x1},3_{y1})\\(1_{x2},6_{y2})\\\\\frac{6-3}{1-0}=\frac{3}{1}=3

The slope is 3. Insert this value:

y=3x+3

In circle C, r = 32 units.<br> What is the area of circle C?
Gnoma [55]

Answer:

A = 1024π units², A ≈ 3216.99 units²

Step-by-step explanation:

The equation of the area of a circle is A = πr², where A = area and r = radius.

Given that, we can plug in r as 32 units: <em>A = π(32 un.)²</em>

Simplifying that gives us A = 1024π units², or A ≈ 3216.99 units²
