Answer:
$5728
Step-by-step explanation:
$4000 is deposited into an account with 4.8% interest.
We assume that there are no withdrawals from the account.
Then we are asked the determine the amount will be there in the account after 9 years.
From the formula of simple interest, the final amount in the account after 9 years will be 
dollars. (Answer)
Answer:
You can
Step-by-step explanation:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them.
For perpendicular lines, m1m2 = -1 or m2 = -1/m1; where m1 and m2 are the slopes of the lines.
Here line 1 is 2x - y - 7 = 0
y = 2x - 7; Hence m1 = 2
m2 = -1/2
Required equation y - y1 = m2(x - x1)
y - (-1) = -1/2(x - 4)
y + 1 = -1/2x + 2
y = -1/2x + 2 - 1
y = -1/2x + 1
Use Pythagorean theorem to find BC
AB^2 + BC^2 = AC^2
6^2 + BC^2 = 10^2
36 + BC^2 = 100
BC^2 = 64
BC = 8
If AC = 10, CD and AD = 5
Tan = opp/adj
Tan = 5/8
Triangle BCD is a 45-45-90 triangle
CD = BD = 5
Sec = inverse cos
sec = hyp/adj
Sec = 8/5
