Answer:
a)

b)
The total amount accrued, principal plus interest, from compound interest on an original principal of $ 4,200.00 at a rate of 3.6% per year compounded 12 times per year over 10 years is $5667.28.
Step-by-step explanation:
a. Write the function that represents the value of the account at any time, t.
The function that represents the value of the account at any time, t

where
P represents the principal amount
r represents Annual Rate
n represents the number of compounding periods per unit t, at the end of each period
t represents the time Involve
b) What will the value be after 10 years?
Given
The principal amount P = $4200
Annual Rate r = 3.6% = 3.6/100 = 0.036
Compounded monthly = n = 12
Time Period = t
To Determine:
The total amount A = ?
Using the formula

substituting the values


$
Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 4,200.00 at a rate of 3.6% per year compounded 12 times per year over 10 years is $5667.28.
Answer:
(12,3)=x1,y1
m=-1/4
we have,
y-y1=m(x-x1)
y-3=-1/4(x-12)
4y-12=-x+12
x+4y-21=0 is the required eqn
Answer:
which angles do you mean its kinda confusing
Step-by-step explanation:
The equation for finding the area of one triangle is A=1/2(B)(H)
because we have two triangles, we do not need to divide the answer by two.
That being said, 8 times 12 is 96.
By installing a sprinkler for every 10 sq ft. of land we divide that by 10 and get 9.6
Because the decimal value is above 5, my answer would be that you need 10 sprinklers.
Answer:

Step-by-step explanation:
Here, we assume that point A is (-1, 0) and point B is (z, 2). Since angle BAD is 60°, we have ...
2/(z+1) = tan(60°) = √3
z = (2/√3) -1
Putting the value of z into the equation for the parabola lets us find "a".
2 = a(z +1)(z -5) = a(2/√3)(2/√3 -6)
Then ...
a = 2/(4/3 -12/√3) = (6√3)/(4√3 -36)
a = -(3+9√3)/52 ≈ −0.357470332079
