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)
Answer:
1/9 1/10 1/11 1/12 1/13 and so on
Step-by-step explanation:
The transformation from 1 to 2 is a translation, as the shape is moved from one point to another with no rotation, reflection, or change in size.
The transformation from 2 to 3 is a reflection, as the shape is now upside down. It is still the same distance from the y-axis.
The answer is D. translation, then reflection.
Answer:
29
Step-by-step explanation:
9 + 25 + 53
87
87 ÷ 3

Answer:
21.75 or 
Step-by-step explanation:
You have to convert from a mixed number to a decimal. You can follow the following steps: To do this:
1.) You must divide the fraction's numerator by the denominator.
2.) You must now add the quotient obtained to the part of the Whole number.
you will get:

The scale of the image that maps "Figure a" to "Figure b" is:

3.) You have to multiply by 7.25 the length of the corresponding side of "Figure A" in order to find the value "x."
The final result will be:
