Answer:
your answer is c
Step-by-step explanation:
50-x^2=0
Move the x^2 to the other side
x^2=50
Now take the square root of both sides
x=+_(50)^1/2 (^1/2 means square root)(+_ is plus or minus. Sorry XD)
Now simplify the square root
X=+_5(2)^1/2
Voila. The answer is C
The maximum value is actually the maximum of y
So, you don't need to care about the stuff inside cosine function,
Cosine function is always within the range of [-1,1]
So here, ymax = -1 + 6* 1 = 5
To write the coefficients of the 8 terms, either start with a combination of 7 things taken 0 at a time and continue to 7 things taken 7 at a time or use the 7th row of Pascal’s triangle.
For the first term, write x to the 7th power and 3 to the 0 power. Then decrease the power on x and increase the power on y until you reach x to the 0 and y to the 7.
Simplify by evaluating the coefficients and powers of 3.
Answer:
(d)
Step-by-step explanation:
Bond's par value = $500
market value of the bond = 88.754% * 500
= 443.77
Commission rate charged by broker A = 3.1%
Commission of broker A =
*443.77
= $13.75687
Commission of broker B = $24
Difference between the commission of broker A and broker B = 24-13.756
= $10.24
Hence, (d) Broker A's commission will be $10.24 less then Broker B's.
