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:
56 degrees if I am not mistaken
Step-by-step explanation:
The first one. if you use one of the points to substitute the variables, you’ll see that the equation is true
Question 1)The given parabola is:

First we need to convert this equation to the general form similar to:

So, the given equation will be:

Comparing given equation with the general equation, we can write:
p = 2
h = -12
k= -16
The focus of the parabola with squared x terms lies at (h , k+p)
Using the values, we get the focus point of the given parabola (-16, -10)
Question 2.
The equation of the parabola is:

This means:
p=4
h = -3
k =1
The directrix of the parabola with squared y term has the equation of the form:
x = h - p
Using the values, we get
x= - 3 - 4 = -7
So, the equation of the directrix of the parabola will be x = -7
There are two factors. The factors are 3x and y+5
The factors are the pieces that multiply to get the overall result. Another example of factors: 3*6 = 18 where 3 and 6 are the two factors (18 is the product; aka result of multiplication)
