I believe this is compound interest so we would use the formula:
FV = PV × (1 + r)n
So it would be A = p (1 = r) ^t
Input the numbers:
A = p (1 + 3 3/4%) ^10 = 7225.22
<span>2 log 3(x-1)=log(4 x 2-25)
1. Determine the domain. Since the input to the log function cannot be zero or negative, 4x^2-25 must be </span>≥ 0. Thus, x^2 must be >0, or x>0. Same domain applies to log (3(x-1); x must be > 0.
2. Rewrite <span>2 log 3(x-1) as log 3(x-1)^2.
3. Then we have </span>log 3(x-1)^2 = log(4 x 2-25). We can discard the operator "log" from both sides: 3(x-1)^2 = 4 x 2-25. There are various ways in which to solve this. Since you're supposed to "use technology,"
graph y = 3(x-1)^2 and y = 4x^2 - 25 on the same set of axes. Determine, using visual estimation or your calculator's tools, the value or values of x that satisfy this equation. My result was x=3, y =11.
Answer:
Step-by-step explanation:
<u>Subtract 5 from both sides.</u>
- <u />
<u />
- <u />
<u />
<u>Divide both sides by 2.</u>

Answer: C. 6 1/6
Step-by-step explanation:
2 * -5 * -7 = -10 * -7 = 70
70 + 4 = 74
3 * 4 = 12
74/12 = 6 1/6
