Δ FCD is a right triangle ( 3² + 4² + 5² ).
10 : EB = 5 : 3
5 EB = 30
EB = 6
With Pythagorean theorem:
CE² = 10² - 6² = 10 - 36 = 64
CE = 8
ED = 5
AB = 2 · 5 = 10
Answer: The length of the side AB is 10.
Recall that
is only defined for
, and under this condition we have that
. But 1.7 > 1, so
is not a real number.
Answer:
$14.42
Step-by-step explanation:
Price of Album - $17.00 * .20 = 3.4 (this is the discount)
Then subtract 3.40 from 17.00 to get 13.60
Add the sales tax in by doing $13.60 * 0.06 = $0.82
Add that to the 13.60 to get $14.42 for the total after discount and after tax.
Answer:
110
Step-by-step explanation:
22/4=5.5
5.5*20=110
Use slope intercept form to write the equation y=mx+b m (slope of the line) will be the hourly fee, and b (y-intercept) will be the one-time transportation fee.
y=30x+20
to find the cost of renting a canoe for 6 hours, plug 6 into the equation replacing x
y=(30×6)+20
y=180+20=$200
Sorry, I can't graph the line, but I would number the x-axis of the coordinate plane (graph) by 1s or 2s (for the hours), and the y-axis by 20s (for the cost)
