split into 5 equal triangles

base =5, height =3.44, formula for area=(base)(height)(0.5)

area of each triangle =(5)(3.44)(0.5)=8.6

Find the equation of the line that passes through the given points. (1, 4.5) and (3, 6)

Zanzabum

Answer:

y=0.75x+3.75

Step-by-step explanation:

The slope is

$\frac{6 - 4.5}{3 - 1} = \frac{3}{4}$

Substituting into point-slope form,

y - 6 = 0.75(x - 3)

y - 6 = 0.75x - 2.25

y = 0.75x + 3.75

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
