(1-cos0)(1+cos0) pls help​

Mathematics
1 answer:
topjm [15]3 years ago
6 0

Answer:

sin²Ф

Step-by-step explanation:

I doubt that you actually meant "cos 0" ... that has a value of 1.

If you meant  (1-cos Ф)(1+cos Ф), then this product is 1 - cos²Ф.

That, in turn, is equal to sin²Ф

McKenzie buys 250 shares of stock for $12 a share and pays a 2% commision. She sells the stock 3 years later for $18 a share and
Artemon [7]
250 shares for $ 12 per share......250 * 12 = 3000
plus the 2% commission......3000(1.02) = 3060...so the commission is $ 60

she then sells her stock (250 shares) for $ 18 a share....
250 * 18 = 4500
plus the 1% commission....4500(1.01) = 4545...so the commission is $ 45

net proceeds is the amount received by the seller after all costs and expenses are deducted...

expenses : 3000 + 60 + 45 = 3105
revenue : 4500

net proceeds = 4500 - 3105 = $ 1395 <==

Write the equation of a line that passes through points (0,4) and (-2,-3) in slope intercept form
Otrada [13]

y=mx+b is the equation of a line;

m=slope , b= y-intercept

You can find the slope with this following equation: (y(2)-y(1))/(x(2)-x(1))

In this case the points are (0,4) and (-2,-3). The first set being (0,4) and the second (-2,-3). This means (0,4) can be expressed as (x(1),y(1)) and (-2,-3) expressed as (x(2),y(2)). Plugging these numbers into the slope equation gives us: (-3-4)/(-2-0) = -7/-2 = 7/2.

m= 7/2 ; so we have : y= (7/2)x+b

We are give a set of points which it passes through, we can simply plug them in:

4 = (7/2)(0)+b (0 is the x and 4 is the y)

We get 4 = 0 +b .... 4=b

our final equation is : y=(7/2)x+4
