Answer:
(b) 1
Step-by-step explanation:
To differentiate 
we will need the product rule:
.
We have 
, so the following equation is true by the transitive property:
By subtraction property we have:
Since 
, then we can divide both sides by 
:
This implies 
is constant.
So we have that 
where 
is a real number.
Since 
and 
, then by transitive property 
.
So 
.
Checking:
So the following conditions were met.
So, we know that 40 hours is $390 and 4 * 10 = 40, therefore, we just have to divide $390 by 4 to get $97.5, meaning that Zoe made $97.5 in 10 hours of work.
.82
When changing a percentage to a decimal you will divide the number by 100. 82/100= .82
To change it back to percentage you will take .82 and multiply by 100 or simply move the decimal two stops to the right, making 82. or 82%
3/4 divided by 1/16 = 3/4 x 16 = 12 servings
<u>Area of Banner is 4 sq.ft.</u>
<u>Step-by-step explanation:</u>
Class made 20 smaller rectangles
dimension of each rectangle = 3/5 ft × 1/3 ft
Area f banner = 20 * ( area of 1 rectangle)
⇒ 20 * ( 3/5 * 1/3 )
⇒ 20 * 0.2
⇒ 4 sq.ft
<u>Area of Banner is 4 sq.ft.</u>
