Answer: sin(a+b)= sin(a)*cos(b)+sin(b)*cos(a).

Step-by-step explanation: we can write some trigonometric functions in different ways (some more simplified that others), in the case of the given problem, the expanded equivalent of the expression sin(a+b) can be written as follows:

sin(a+b)= sin(a)*cos(b)+sin(b)*cos(a).

Estimate the total percentage of complaints about parking difficulties and the location of the store. (nearest whole percent)
AysviL [449]

Answer:

Therefore the total  Complains about parking difficulties=32.26%

Therefore the total  Complains about the location of the store=25.81%

Step-by-step explanation:

Given ,

Complains about difficulty parking = 250

Complains about isolated location = 200

Complains about ruled sales clerks=150

Complains about too expensive=125

Complains about confusing layout= 50

Total complains = (250+200+150+125+50)

                          =775

Therefore the total  Complains about parking difficulties

=\frac{250}{775}\times 100 %

=32.26%

Therefore the total  Complains about the location of the store

=\frac{200}{775}\times 100 %

=25.81%

When given a problem in a real-world situation, how can you identify the slope and y-intercept?
Mrac [35]
The slope is how much something increases or decreases by at a constant rate, for example if johnny buys 3 oranges every time he goes to the store the slope would be 3. the y-intercept is how many things you start with so if johnny already had 5 oranges before he went to the store the y-intercept would be 5. the equation for that situation would by y=3x+5... 3x is the 3 oranges johnny buys each time he goes to the store (the slope) and 5 is how many oranges he started with before going to the store at all (y-intercept)

Beverage A and Beverage B are sold in identical cans. Beverage A is 6% sugar. The portion of Beverage B that is sugar is 0.21. H
muminat

Answer:

3.5 more times sugar in B

Step-by-step explanation:

We need to see that the fact that Beverage B is 0.21 sugar can be translated to percentages, just by multiplying and dividing by 100 to get it easier to see:

0.21 * 100 /100 =  21/100 = 21% percent

This means that for every 100 units, 21 are sugar.

Now we can compare percentages directly, as both have the same volume because are sold in identical cans. We need to get how many times is 21 greater than 6. The only thing we need to do is the ratio between them:

21/6= 3.5

This implies that 21 is 3.5 greater than 6, you can verify it by multiplying 6 by 3.5 and getting 21.

So, B has 3.5 times more sugar than A.
