y= In(x)-5
Step-by-step explanation:
Answer:
The answer is B
Step-by-step explanation:
S.A of pyramid = base area × 4(area of triangle)
base area = (24×24)in
= 576in²
area of triangle = (1/2)×24×12
= 144in²
S.A = 576 + 4(144)
= 1152in²
Answer:
Step-by-step explanation:
The formula for compound annual interest is A = P(1 + r)t where
A = Accumulated or final amount (double $500 = $1000)
P = Principal or original amount ($500)
r = Rate as a decimal (0.08)
t = Time in years
1000 = 500(1 + 0.08)t
2 = 1.08t
Take the logarithm of both sides. I prefer the natural logarithm ln, but if you're more comfortable with base 10 logs they will work just as well
ln(2) = ln(1.08t)
ln(2) = t*ln(1.08)
t = ln(2)/ln(1.08)
t = 9.0065 years
Check: 500*1.089.0065 = $1000
50-8=42(half of his score)
42*2=84(whole score)
s=84
