Answer:

Some have multiple choices. See below for additional comments.

  • a) iii
  • b) i
  • c) v
  • d) ii
  • e) iv

Step-by-step explanation:

i -- slope-intercept form. Shows the slope and the y-intercept

ii -- slope-intercept form. Shows the slope and the x-intercept

iii -- intercept form. Shows both the x- and y-intercepts

iv -- standard form.

v -- point-slope form. Shows the slope and one point on the line.

vi -- another point-slope form. Shows the slope and one point on the line

__

With the above forms in mind, ...

a) both intercepts are best shown in form iii

b) the slope is shown in forms i, ii, v, vi. Form i is the most uncluttered.

c) points are shown in forms v and vi. Form v may be least confusing.

d) the sign can be readily determined in form ii.

e) testing the given point is easily done using forms ii and iv. Form iv may be the best for this.

_____

<em>Additional comments</em>

Since each of these forms of the equation has utility in different situations, it can be worthwhile to learn the different forms. For example, I like the standard form for making perpendicular lines, though any of the "slope-" forms can be useful for that, too. The useful form to start with will be the one that best relates to the information given. (For two points given, there is a "2-point form" not shown here.)

Present value (PV) of annuity = USD 100,000 at 5% for 4 years

Present Value of Annuity of $1

Find the vale of x need help
babunello [35]

Answer:

x=45 degrees

Step-by-step explanation:

You can see based off of the markings on the 2 sides, that it is an isosceles triangle, so that means the 2 base angles are equal.

so 2x+90=180 degrees

so 2x=90 degrees

x=45

sweet-ann [11.9K]
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:-)
