Complete question :
The Quick Ship company uses the function C(w) to calculate the cost in dollars, C, for shipping an item weighing w ounces. C(w) 0.45w 0.35w + 1.6 if 0 < W 16 Which statement about the shipping rate is true?
A.it is possible that an item weighing less then 16 ounces could cost the same as an item weighing more than 16 ounces
B. to find the charge for shipping a package weighing more than 16 ounces, multiply the weight by $.035.
C. Shipping at the second rate will always cost $1.60 more than shipping at the first rate
D. if the weight is greater than 16 ounces,the shipping rate is $.0.35 per ounce, plus $1.60
Answer:
C. Shipping at the second rate will always cost $1.60 more than shipping at the first rate
Step-by-step explanation:
The shipping rates are :
C(w) = 0.45w
Second rate :
C(w) = 0.35w + 1.6
For the first shipping rate, it only has a rate of change value which varies based on the weight of item to be shipped, C(w) = 0.45w.
However, the second shipping rate includes a fixed rate and rate based on the weight of item. This fixed rate implies that regardless of the weight of item to be shipped, a fixed fee is charged which is $1.60. This means that the shipping fee at the secind rate will always be $1.60 greater than thebfirst shipping rate.
396
/x−10
=−22
Step 1: Multiply both sides by x-10.
396=−22x+220
−22x+220=396(Flip the equation)
−22x+220−220=396−220(Subtract 220 from both sides)
−22x=176
−22x
/−22
=
176
/−22
(Divide both sides by -22)
x=−8
For a relation to be function, every x value should have its unique image in co-domain. If x is related to more than one y value, then that relation is not a function
In 1, as you can see, 1 related to -7 as well as 8. Which means 1 has two images viz. -7 and 8. But for a relation to be function, x should have only one image. Thus, it is not a function.
The worst is the 4th one in which -2 has 4 images.
Therefore, only relation B is a function.
Answer:
585 and 54
Step-by-step explanation:
Answer:
Volume of a sphere = 4/3πr³
π = 3.14
r = radius which is 3in
Volume = 4/3 × 3.14 × 3²
= 37.68
= 38 cubic inches to the nearest hundredth
