Answer:

((2,-5),(4,-5),(6,2),(8,3))

((-1,5),(3,5),(6,5),(9,5))

((0,3),(4,2),(-1,7),(0,3))

Step-by-step explanation:

For a set of ordered pairs to be a function, no x value can have two different y values.

In the three functiosn above, every x value has one and only one y value corresponds with it.

((0,3),(4,2),(-1,7),(0,3)) Is still a function because when x is zero, there is only one y value that corresponds with it, which is 3.

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator

777dan777 [17]

Answer:

V = 3,367.6 cm³

Step-by-step explanation:

Diameter of sphere (D) = 18.6 cm

radius (r) = ½(18.6) = 9.3

π = 3.14

Formula for volume of a sphere = ⁴/3πr³

Plug in the values

V = ⁴/3 × 3.14 × 9.3³

V = ⁴/3 × 3.14 × 804.357

V = (4*3.14*804.357)/3

V = 3,367.57463

V = 3,367.6 cm³ (nearest tenth)

Seth invested n dollars into an investment fund last year. After a period of one year, the value of his investment can be repres

Crank

Answer: A. The value of his investment decreased by 16% during this time period.

Step-by-step explanation:

Here the initial amount = n

Final amount after 1 years = 0.84n

The total change in the initial amount = n - 0.84n = 0.16 n

$\text{ The percentage change in the initial amount} = \frac{\text{ the total change in initial amount}}{\text{ Initial amount}}\times 100$

= $\frac{0.16 n }{n} \times 100 = 16\%$

Thus, the amount is decreases by 16% in one year,

⇒ Option A is correct.
