an = 27 + (n-1)(-6)
Answer:
B)Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90 clockwise
Step-by-step explanation:
This is because, to locate a point rotated by 90° from point A, we first draw a circle with the origin as its center and a radius of the origin and point A. We then locate a point on the line that is 90° clockwise from point A. For a 90° clockwise rotation, for a given pair of coordinates, (x,y), the resulting pair of coordinates is (y,-x). So, for the coordinates (1,4), the resulting coordinates we are looking for is (4, -1), which is the point rotated 90° clockwise from point A. The point is thus (4,-1).
Answer:
$3714.18
Step-by-step explanation:
From the question;
Amount invested is $3300
Rate of interest 3% per year compound interest
Time is 4 years
We want to determine the amount that accrued after 4 years
In this case we are going to use the compound interest formula;
That is;
where A is the amount, P is the principal , r is the rate of interest and n is the time taken.
Therefore;
= $3714.18
Therefore, the amount accrued after 4 years is $3714.18
The answer is D
Hope this helps
Answer:
<em>72</em>
Step-by-step explanation:
Since every year she watches it 3 times, she would watch 3·24 times when she is 24. 3·24=3·20+3·4=60+12=72
