Answer:

y = 2(x-2)^2+4  is the equations the parabola

Step-by-step explanation:

The standard equation of parabola is given by:

y = a(x-h)^2+k           ....[1]

where,

a is the non zero real number and

(h, k) is the vertex of the parabola.

As per the statement:

The vertex if the parabola below is at the point (2,4)

⇒(h, k) = (2, 4)

⇒h =2 and k =4

Substitute these in [1] we have;

y = a(x-2)^2+4

Since, the point (3,6) is on the parabola

⇒x = 3 and y = 6

then;

6 = a(3-2)^2+4

6 = a+4

Subtract 4 from both sides we have:

2= a

or

a = 2

⇒y = 2(x-2)^2+4

Therefore, the equations the parabola is, y = 2(x-2)^2+4

A sound wave travels through iron at a rate of 5120\,\dfrac{\text{m}}{\text{s}}5120 s m ​ 5120, start fraction, start text, m, e
klio [65]

Answer:

18432 km/h

Step-by-step explanation:

It is given that a sound wave travels through iron at a rate of 5120 m/s.

We know that

1 km = 1000 m

1 hour = 60 minutes

1 minutes = 60 second

Using these conversions we get

1 m = 0.001 km

1 hour  = 3600 second

5120\text{ m/s }=5120\times 0.001\times 3600\text{ km/h}

5120\text{ m/s }=18432\text{ km/h}

Therefore, the sound wave travels through iron at a rate of 18432 km/h.

What Is the Answer To number 1 ?
DochEvi [55]

Answer: 4 apples for $3.64


Step-by-step explanation:

The best buy is going to be the one that costs the least. To figure this out, you divide the number of apples by the price. (do not round)

4/3.64=1.09

9/8.01=1.23

14/12.43=1.12

24/21.12=1.13

As you can see, the 4 apples for $3.64 is the better choice since the number is the least.
