Answer:
1200
Step-by-step explanation:
30 * 40 = 1200
the actual total cost would be 1326 because 39 * 34 = 1326
The answer is

The expression is:

Let's factorize it:

Since

, then:

Cancel x(x-3) and simplify:
Answer:
(b) 7.28 cis(105.945°)
Step-by-step explanation:
The trig form of a vector is always ...
magnitude(cos(angle)·i +sin(angle)·j)
Sometimes, that is abbreviated ...
magnitude cis(angle) or magnitude∠angle
where the "angle" is measured counterclockwise from the +x axis.

The forms showin in choices C and D can be rejected immediately because the sine and cosine coefficients are incorrectly placed. To differentiate between choices A and B, you need to know whether the angle is greater than 90°. The terminal point is above and left of the initial point, so the angle must be <em>more than 90°</em>. (It can help to plot the points on a graph.)
u = 7.28(cos 105.945°i + sin 105.945°j)
Since p=24 and to get p you do 3w+3w+w+w which equals 8w=24 and 24/8 is 3 so your answer is 3
