Answer:
<h2>|1.7| = 1.7</h2>
Step-by-step explanation:
Definition of absolute value:
|a| = a if a ≥ 0
|a| = -a if a < 0
Examples:
|2| = 2
|-2| = -(-2) = 2
|0.45| = 0.45
|-0.45| = -(-0.45) = 0.45
|1000| = 1000
|-1000| = 1000
Therefore
|1.7| = 1.7
A used book store buys a hardback book for $1.50 and then sells it for $5. Over time, the store sells the same number of books it buys. The store manager can use the equation P(x)=5x−1.5x to determine the store's profit, P(x), where x is the number of books that the store sells. Which statement about the book store is true based on the profit equation?
Cost Price of book, C.P.=$1.50
Selling Price of book, S.P.=$5
PROFIT=S.P. -C.P.
So, Profit=$5-$1.50=$3.50
So, Profit=$3.50 on each book
Or, we are given P(x)= 5x-1.50x
Or, P(x)=3.50x
For each book, we must divide the profit P(x) by x, that is, number of books
So, Profit for each book sold is $3.50

Answer:
The correct answer is last option
surface area = 104 yd²
Step-by-step explanation:
Formula:
Surface area of cylinder = 2πr² + 2πrh
Where r is the radius and h is the height of cylinder
To find the surface area of cylinder
Here r = 4 yd and h = 9yd
Surface area = 2πr² + 2πrh = 2π * 4 * 4 + 2π *4 *9
= 32π + 72π = 104π yd²
Therefore the total surface area of given cylinder = 104π yd²
The correct answer is last option .
