Step-by-step explanation:
Answer:
variable and fixed costs
Step-by-step explanation:
First find the yearly payment using the formula of the present value of annuity ordinary
The formula is
Pv=pmt [(1-(1+r)^(-n))÷r]
Pv present value 276475
Pmt yearly payment ?
R interest rate 0.0565
N time 30 years
Now solve for pmt
The formula change to be
Pmt=pv÷ [(1-(1+r)^(-n))÷r]
Plug in the equation above
Pmt=276,475÷((1−(1+0.0565)^(−30))÷(0.0565))=19,339.22
Now find the cost of the principle and interest after 30 years by multiplying the yearly payment by the time
19,339.22×30=580,176.60...answer
Hope it helps:-)
Answer:
16. B
17. B
Step-by-step explanation:
16. The intercept form of the parabola is

where
are two x-intercepts.
In your case,

so

To find <em>a</em>, substitute coordinates of the point (-6,-4) parabola is passing through

and

17. The vertex form of the parabola equation is

where <em>(h,k)</em> are the coordinates of the vertex and sign "-" because parabola goes down.
In your case, vertex is (2,3), so

The vertex is 3 units from the focus, then

The equation of the parabola is

<h3>
Answer: 25</h3>
==========================================================
Work Shown:
x = number of $2 coins
y = number of $10 coins
x+y = 43 coins total
x = 43-y
2x = value of just the $2 coins only
10y = value of all the $10 coins only
2x+10y = total value of all coins mentioned
This value must be greater than $278, so,
2x+10y > 278
2( x ) + 10y > 278
2(43-y)+10y > 278
86-2y+10y > 278
8y+86 > 278
8y > 278 - 86
8y > 192
y > 192/8
y > 24
The smallest y can be is y = 25.
We need at least 25 coins worth $10 each.
