The elf ate 5/8 of the 10 muffins you had
to figure out how many were eaten, you have to multiply 5/8 by 10
5/8 * 10 = 6.25
now to figure out how many are left, subtract 6.25 from 10
10-6.25 = 3.75
3.75 muffins are left
hope this helped
Answer: a) -13.25 N, b) 1.78 m/sec
Step-by-step explanation:
Since we have given that
where
As we know that
Here, x= 0.5 m
So, it becomes,
Now, we need to find the velocity when it crosses the origin,
Hence, a) -13.25 N, b) 1.78 m/sec
Answer:
The coordinate axes divide the plane into four quadrants, labelled first, second, third and fourth as shown. Angles in the third quadrant, for example, lie between 180∘ and 270∘ &By considering the x- and y-coordinates of the point P as it lies in each of the four quadrants, we can identify the sign of each of the trigonometric ratios in a given quadrant. These are summarised in the following diagrams. &In the module Further trigonometry (Year 10), we saw that we could relate the sine and cosine of an angle in the second, third or fourth quadrant to that of a related angle in the first quadrant. The method is very similar to that outlined in the previous section for angles in the second quadrant.
We will find the trigonometric ratios for the angle 210∘, which lies in the third quadrant. In this quadrant, the sine and cosine ratios are negative and the tangent ratio is positive.
To find the sine and cosine of 210∘, we locate the corresponding point P in the third quadrant. The coordinates of P are (cos210∘,sin210∘). The angle POQ is 30∘ and is called the related angle for 210∘.

Answer:
50°
Step-by-step explanation:
<u>The sum of a triangles' angles is 180°</u>
Now set up an equation:
180 - (10 + 120) = ___
180 - 130 = 50°
