Each transformation will give these following coordinates

Translation 7 units right gives E(4, 4), F(8, 3), G(10, 6), and H(8, 6) as shown in brown in the diagram below

Reflection on the y-axis gives E(3, 4), F(-1, 3), G(-3, 6) and H(-1, 6) as shown in green in the diagram below

Reflection on the x-axis gives E(-3, -4), F(1, -3), G(3, -6) and H(1, -6) as shown in red in the diagram below

Translation 5 units down gives E(-3, -1), F(1, -2, G(3, 1) and H(1, 1) as shown in purple in the diagram below

The intensity, I, of a sound varies inversely with the square of the distance, r, from the source of the sound. Write an equatio
charle [14.2K]

Answer:The  equation relating I, r, and k is I =K/r²

Step-by-step explanation:

The intensity, I, of a sound varies inversely with the square of the distance, r, from the source of the sound can be written as

I ∝ 1/r²

Introducing the constant of proportionality, K we have that

I =K x 1/r²

Therefore , the  equation relating I, r, and k is I =K/r²

Find a number less than 19 that has more factors than 19,21,23and 25
katen-ka-za [31]
A <em>factor</em> is a number that your number is divisible by.

19 has two factors: 19 and 1.
23 also has two factors: 23 and 1.

21 has four factors: It is divisible by 21 and 1, but also by 3 and 7.
25 has three factors: It is divisible by 25, 1, and 5.

We need a number less than 19 that has five or more factors.
What we can do is multiply a bunch of numbers together (so that we know that our number will be divisible by them) to give it a lot of factors.

Let's try 2 × 2 × 3. This gives us 12.

12 has <em>six</em> factors: 12, 1, 2, 6, 3, and 4.

adoni [48]
C(x)=rx+s  we are told that x=3, c(x)=21, and s=3

21=3r+3  divide both sides by 3

7=r+1  subtract 1 from both sides

6=r  so now c(x) becomes:

c(x)=6x+3
