Answer:
pq = 7
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = p(5, 4) and (x₂, y₂ ) = q(- 2, 4)
pq = 
= 
= 
= 7

Answer:
<em>To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.</em>
Step-by-step explanation:
<u>Proportions</u>
The hybrid car can travel 40 miles per gallon.
Since one mile is equivalent to 1.6 Km, the distance traveled per gallon is 40*1.6 = 64 Km.
Now the distance is expressed in Km, we can find the gallons needed to travel 20 Km, by calculating 20/64 = 0.3125.
To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.
The balance after one year if you deposit one $50 envelope each month, all year is $613.95.
<h3>What is the balance after one year?</h3>
The balance after 1 year can be determined using this formula:
Amount deposited monthly x annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
Where:
- r = interest rate = 5% /12 = 0.417%
- n = number of years = 1 x 12 = 12
Annuity factor = 1.004167^12 - 1 / 0.00417 = 12.279082
Balance = 12.279082 x 50 = $613.95
