Find the distance between each pair of points. round your answer to the nearest tenth.

goldenfox [79]

Answer:

5.4

Step-by-step explanation:

To find the distance between each pair of points, we use the distance formula, which is:

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

So we have

$x_{1} = 2\\ x_{2} = 4\\y_{1} = 8\\y_{2}=3$

When we plug in the values into the formula we get:

d = $\sqrt{(4-2)^2 + (3-8)^2}$

d = $\sqrt{4 + 25}\\ =\sqrt{29}\\ =5.4$

Nataly [62]

Answer:

The function is missing in the question. The function is $C(x) = 0.8x^2 -544x +97410$

The answer is 4930

Step-by-step explanation:

Unit cost of a car is given as

$C(x) = 0.8x^2 -544x +97410$

Cost will be minimum when

x = -(-544)/ 2 x 0.8

= 340

Therefore, minimum cost for unit car is

$C(x) = 0.8x^2 -544x +97410$

$= 0.8(340)^2 -544(340) +97410$

= 4930
