Struggling, can anyone help me out on these three functions? It would be much appreciated. Thanks so much!! :)

Maurinko [17]

Answer:

1. a) Not function

b) Domain is all real numbers greater than or equal 2 (x ≥ 2)

c) The range all real numbers ( -∞ < y < ∞)

2. a) Function

b) The domain is all real numbers (-∞ < x < ∞)

c) The range is all real number greater than or equal -4 (y ≥ -4)

3. a) Not function

b) domain is {-3 , -2 , -1 , 0 , 1 , 3}

c) The range is {-2 , -1 , 1 , 2 , 3 , 5}

Step-by-step explanation:

1. Not a function because some x has more than one corresponding y

Note: If we draw vertical line and move it left and right over the curve it will cut the cure in more than one point that means one x has more than one y

2. Function because every x has one corresponding y

3. Not function because some x have more than one corresponding y like

(-3 , -2) (-3 , 2) and (3 , -1) (3 , 2)

The volume of a certain right circular cone is 30 cubic inches. What is the volume, in cubic inches, of a second right circular

mrs_skeptik [129]

Answer:

V = 15 in.³

Step-by-step explanation:

The original cylinder has radius r and height h.

V = πr²h

Its volume is 30 in.³, so

πr²h = 30 in.³

The new cylinder has radius (1/2)r and height 2h.

Its volume is

V = π(r/2)²(2h)

V = πr² × 2h/4

V = πr²h/2

πr²h is the volume of the original cylinder, and it is 30 in.³.

V = 30 in.³/2

V = 15 in.³

Kia rides her bicycle at 20 miles per hour. Which equation represents the situation?

sergejj [24]

Answer:

(A)d=20h

Step-by-step explanation:

If Kia rides her bike at 20 miles per hour.

20 miles per hour is referred to as the Kia's Speed.

Now we know that:

$$Speed=\frac{Distance \:Travelled}{Time \:taken}$

Given:

Number of hours traveled=h
Distance traveled=d
Speed = 20 mph

Substituting these three into the formula above, we have:

$20=\dfrac{d}{h}\\$

Cross multiply

d=20h

<u>The correct option is A.</u>
