You buy 6 shirts. So $77 minus $5=$72
Then you divide $72 by $12 and you get 6 shirts
2.32 x 10⁵ = 232000
This can be solved by multiplying 2.32 to the product of 10 multiplied 5 times.
10⁵ = 10 * 10 * 10 * 10 *10
10⁵ = 100,000
2.32 x 100000 = 232000
The given equation is the standard form of a decimal number. It is used to write down a very large or very small number easily.
There are a lot of standard forms. Like: Standard form of an equation and Standard form of a polynomial.
Use the following identities:
![sec^2 = 1 + tan^2 \\ \\ sec = \frac{1}{cos} \\ \\ sin^2 = 1 - cos^2](https://tex.z-dn.net/?f=sec%5E2%20%3D%201%20%20%2B%20tan%5E2%20%5C%5C%20%20%5C%5C%20sec%20%3D%20%5Cfrac%7B1%7D%7Bcos%7D%20%5C%5C%20%20%5C%5C%20sin%5E2%20%3D%201%20-%20cos%5E2)
Also because the angle is in quadrant 3, sin must be negative.
Therefore
![sin = - \sqrt{1 - \frac{1}{1 + tan^2}}](https://tex.z-dn.net/?f=sin%20%3D%20-%20%5Csqrt%7B1%20-%20%5Cfrac%7B1%7D%7B1%20%2B%20tan%5E2%7D%7D)
Subbing in tan = 0.958
Probably a for plot, because It shows how close each value is, or if the values are all scattered around. it gives you a more accurate ways of seeing how close the data is. hope this helped
Answer:
(x²-2x)/(2x+6)
Step-by-step explanation:
When you are asked to divide two fractions just do keep-change-flip. Keep the first fraction, change the ÷ to x and flip the second fraction upside down. So the problem becomes ((x-2)/(x+3)) times (x/2). Then just multiply numerators and multiply denominators.
