For this case we have the following equation:
Where, by definition, we have the following variables:
d (x): the daily expense per truck (in dollars)
x: the daily mileage
Therefore, the domain of the function is given by:
Equivalently:
[0, ∞)
Answer:
The input for the function includes all positive real numbers
option d.
The longest chord on the circle is the diameter, and the center of the circle is the midpoint of the diameter.
Use the midpoint formula to find the center
((x1 +x2)/2 , (y1+y2)/2).. Just substitute them for the solution
the x-coordinates are the same, so you can just subtract the y-coordinates to find the radius.
10.5 - 8 = 2.5
The equation of the circle is (x - h)² + (y - k)² = r² where r is the radius and (h, k) is the center.
(x - 4)² + (y - 8)² = 6.25
Answer:
400 square inches
Step-by-step explanation:
surface area= summation of area of all the faces the object has
out object has 2 triangular faces, and 3 rectangular faces
S.A = 2(0.5bh) + LW +LW+LW
= 2(0.5 x 8 x 15) + (15x7) + (17 x 7) + (7×8)
= 120+105+119+56
= 400 square inches
Answer:
$1.50
Step-by-step explanation:
To find the best deal, we first want to consider price per unit. To find the price per unit, we divide the price by the number of units. For the 10 shin guard package, our price is 14.50, and we divide that by 10 to get 1.45 . Therefore, our unit price for the package of 10 is $1.45 per shin guard. Similarly, we can find the unit price for the package of 15 to be 22.5/15 = $1.50 per shin guard. As 1.50 is greater than 1.45, the lowest unit price is for the package of 10.
The question is asking for us to compare the prices if we bought 30 of each. For the package of 10, we get 1.45*30 (as we're buying 30 for 1.45) = 43.5 as the total price, and for the package of 15, we get 1.5*30 = 45 as our price. As 15 and 10 are both factors of 30, we don't need to worry about converting it back into packages of 10/15. The difference between buying 30 at the lowest and highest unit price is therefore (45-43.5)=1.5 dollars
Answer:
4 blu-rays
Step-by-step explanation:
*Note: I'm rounding up to full dollars to make this easier. You will get the same answer, whether you round up or not.
First, get rid of the shipping cost from the budget.
$150 - $10 = <u>$140 left for blu-rays</u>
Then divide $140 by $30, which is the price for a single blu-ray to get the number of blu-rays Chris can get.
$140 ÷ $30 ≈ 4.6 repeating. You can't have a fraction of a movie, so Chris can get 4 blu-rays
