Start with the Pythagorean theorem{A²+B²=C², A and B are the sides and C is the Hypotenuse/Longest Side.}
2²+4²=C²
4+16=C²
20=C².....{now square root both sides.√}
√20=√C²
4.472= C

P.S.: hope I helped :)

Answer:

the distance is 4.47 linear units

Step-by-step explanation:

Hello, I can help you with this.

you can solve this by using the distance between two points formula.

Step 1

let's remember the distance between two points formula.

Let

P1(x_{1},y_{1})\\P2(x_{2},y_{2})

the distance between P1 and P2 is given by:

d=\sqrt{(x_{2}-x_{1}) ^{2} +(y_{2}-y_{1}) ^{2}} \\

Step 2

all you have to do is put the values into the equation

Let

P1(2,1)

P2(4,5)

then

x_{1}=2\\y_{1}=1\\x_{2}=4\\y_{2}=5\\

d=\sqrt{(x_{2}-x_{1}) ^{2} +(y_{2}-y_{1}) ^{2}} \\\\d=\sqrt{(4-2) ^{2} +(5-1) ^{2}} \\\\d=\sqrt{(2) ^{2} +(4) ^{2}} \\\\d=\sqrt{20}\\ d=4.47

so the distance between A and B is 4.47

I hope it helps , have a great day.

Joe earns $14 an hour and Blaine earns $18 per hour. Joe receives a raise of $1.75 every six months, and Blaine receives a raise
Vanyuwa [196]

Answer:

4 interval of six months.

Step-by-step explanation:

Given: Joe earn $14 per hour

           Blaine earn $18 per hour.

           Joe receives a raise of $1.75 every six months

           Blaine receives a raise of $0.75 every six months.

Lets assume the number of six month intervals be "x".

Now, finding the number of six months interval require to get Joe´s earning equal to Blaine earning.

Forming an equation to find the six month interval

⇒ 14+(1.75\times x)= 18+(0.75\times x)

Solving the equation to find the value of x

⇒ 14+1.75x= 18+0.75x

subtracting both side by 0.75x

⇒ 14+x= 18

subtracting both side by 14

∴ x= 4

Subtituting the value of x, we will get both Joe and Blaine earning as equal.

14+(1.75\times x)= 18+(0.75\times x)

⇒ 14+(1.75\times 4)= 18+(0.75\times 4)

⇒ \$ 21= \$ 21

Hence, after 4 interval of six months, Joe to earn same hourly rate as Blaine.
