2) 4 = 90
5 = 45
6 = 45
16) this one's a bit long :)
PLEASE READ
I MADE A DUMB MISTAKE WHEN WORKING OUT THE HEIGHT
ITS NOT 8.41 ITS 9
SORRY ABOUT THAT
The answer is a histogram
Answer:
.
Step-by-step explanation:
Let C represent total daily charges in dollars and t represent time in hours.
We have been given that a plumber charges $50 for a service call plus $80 per hour.
The amount charged for t hours would be
.
The total amount charged for t hours would be
.
We are also told that plumber spends no longer than 8 hours a day at any one site, this means that time t have a restriction as:

Therefore, our required cost function would be
.
Answer:
(2.5 , 3.5)
Step-by-step explanation:
We can use the midpoint formula . Here the points are , (2,2) and (3,5) .
• <u>Using</u><u> </u><u>Midpo</u><u>int</u><u> Formula</u><u> </u><u>:</u><u>-</u><u> </u>
⇒ M = { (x1 + x2)/2 , (y1 + y2)/2 }
⇒ M = ( 2+3/2 , 5+2/2 )
⇒ M = ( 5/2 , 7/2 )
⇒ M = ( 2.5 , 3.5 )
<h3>
<u>Hence </u><u>the</u><u> </u><u>midpoint</u><u> </u><u>is</u><u> </u><u>(</u><u>2</u><u>.</u><u>5</u><u> </u><u>,</u><u> </u><u>3</u><u>.</u><u>5</u><u>)</u></h3>
Well your formula would be
A = P Q
