First let's find the angles a and b.
We have then:
sin a = 4/5
a = Asin (4/5)
a = 53.13 degrees.
cos b = 5/13
b = Acos5 / 13
b = 67.38 degrees.
We now calculate cos (a + b). To do this, we replace the previously found values:
cos ((53.13) + (67.38)) = - 0.507688738
Answer:
-0.507688738
Note: there is another way to solve the problem using trigonometric identities.
Even function because the highest exponent of the variable is a 6, and 6 is an even number.
Answer:
A. Divide 14 by 2, because each pint has 2 cups
Step-by-step explanation:
Formula:
Divide the volume value by 2
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
y = slope (x) + y - intercept
To find the slope we need to find out how much the x's and y's increase or decrease...
To find the y - intercept if any, simply look for coordinates ( 0 , y ) or 0 and a #.
~~
In this case, as time passes, the water level decreases therefore we have a negative slope.
Time is our x and amount (ft) is our y.
On the x side it increases by 2
On the y side it decreases by 10
Now do y over x ==> 10 over 2 and get 5 ==> m
-5 is our slope and 50 is our y - intercept
~~
The "rate of change" is another word for slope.
Well, slope is - 5ft is our slope.
![y = - 5x + 50](https://tex.z-dn.net/?f=y%20%3D%20-%205x%20%2B%2050)
