A - 90 degrees
B - 110 degrees
C - 78.5 = \pi 5 to the second power
D - 15.3

To find A, the point of intersection of a tangent to the center of a circle always makes a 90 degree angle.

To find B, do 360 subtracted by all known angles while keeping in mind the angle opposite to RST. 

To find C, use the formula to find an area of a circle. In this case, OP = pi r squared.

To find D, you need to realize that it is just a fraction of the circle which is 70 degrees. So you need to use the fraction to find the answer, to do so you use (70/360) times 78.5 which gets you 15.3.

Hope this helps!

1.How much will $5,000 accumulate in 5 years if it earns 6% per annum for the first 3 years and then 8% per annum for the next 2
Pavel [41]

Answer:  Amount after 5 years become $5937.60.

Step-by-step explanation:

Since we have given that

Principal amount = $5000

Time period = 5 years

Rate of interest for 3 years = 6%

Rate of interest for 2 years = 8%

so, Amount becomes

Amount=5000(1+\dfrac{6}{1000})^3(1+\dfrac{8}{100})^2\\\\Amount=5000(1+0.006)^3(1+0.08)^2\\\\Amount=5000(1.006)^3(1.08)^2\\\\Amount=\$5937.60

Hence, Amount after 5 years become $5937.60.
