Given that m and n are parallel, and p is a transversal that is perpendicular to m, give an explanation for why it must also be
IrinaVladis [17]

Answer:

p is perpendicular to n. Proved.

Step-by-step explanation:

See the diagram attached.

Let us assume that mm' and nn' are two straight lines parallel to each other and pp' is a transversal.  

It is given that pp' is perpendicular to mm' i.e. ∠po'm = 90°

Now, since mm'║nn' and pp' is a transversal, so, ∠pon = ∠po'm = 90° {Those are corresponding angles}

So, pp' is also perpendicular to nn'. {Proved}

MARCELLA LANDON WINS THIRD PRIZE IN THE CLEARINGHOUSE SWEEPSTAKES AND
Triss [41]

The amount of money in the account after 10 years is $278,814.10.

<h3>What will be the value of the account after 10 years?</h3>

The first step is to determine the amount she has left to invest.

Amount invested = amount won - amount spent on vacation

$250,000 - $10,000 = $240,000

The second step is to determine the future value of the account. The formula for calculating future value:

FV = P (1 + r)^nm

  • FV = Future value
  • P = Present value
  • R = interest rate = 1/5/12 = 0.125%
  • m = number of compounding =12
  • N = number of years

240,000 x 1.00125^(12 x10) = $278,814.10
