The equation for interest is
'Initial amount (interest rate in decimal form) ^ times compounded EX: years'
your equation would be
400(1.04)^10
which equals 592.097713 (not rounded)
Answer:
3 people attended the banquet
Step-by-step explanation:
The function is given as:
b = 75 + 15n where
b represents the total = 122
n represents the number of people attending = ??
If the total cost of the banquet is 122, how many people attended the banquet?
Hence,
122 = 75 + 15n
122 - 75 = 15n
47 = 15n
Divide both sides by 15
n = 47/15
n = 3.1333333333
Approximately to the nearest whole number = 3
Therefore, 3 people attended the banquet.
Answer:![-3x\sqrt{7}](https://tex.z-dn.net/?f=-3x%5Csqrt%7B7%7D)
Step-by-step explanation:
Don't have much of one, but just took test
Cosa/1+sina + 1+sina/cosa = (cos^2a+1+2sina+sin^2a)/(cosa)((1+sina)
=( 1+1+2sina)/(cosa) (1+sina)
=2(1+sina)/ (cosa) (1+sina)
=2/cosa
=2sec a (verified)
