No it is not linear because it would make a curved line

Linear functions are always first degree (highest exponent on the placeholder is 1)
we see that we have y^2, exponent of 2
2>1 so this is not linear

also, linear means line so it has to be a line to be linear, if yo graphed it, it would not be a line

This expression represents the average cost per game, in dollars, at a bowling alley, where n represents the number of games:

Dmitry_Shevchenko [17]

Answer:

Average Cost per game for 4 games is:

A) $4.75

Step-by-step explanation:

As the question is not complete, lets complete it first.

At the bowling Alley, shoe rentals cost $3 while a games costs $3. The expression that represents the average costs per game 'c' , in dollars, where n is the number of games, is:

$c=\frac{4n+3}{n}$

To find average cost per game, for 4 games, simpli substitute n=4 into the given equation:

$c=\frac{4n+3}{n}\\c=\frac{4(4)+3}{4}\\c=\frac{16+3}{4}\\c = \frac{19}{4}\\c= 4.75$

So Average Cost per game for 4 games is:

c = 4.75$

Please help me with this geometry question

mixer [17]

Answer:

$180+18\sqrt{3}\ in^2.$

Step-by-step explanation:

The surface area of right triangular prism is the sum of area of two base triangles and 3 area of side rectangles.

The area of base triangle is

$A_{base}=\dfrac{a^2\sqrt{3}}{4},$

where a is the length of the side of equilateral triangle. In your case, a=6 inches. Thus,

$A_{base}=\dfrac{6^2\cdot\sqrt{3}}{4}=9\sqrt{3}\ in^2.$

The area of side rectangle is

$A_{side}=ah,$

where h is the height of the rectangle. In your case, h=10 inches. Thus,

$A_{side}=6\cdot 10=60\ in^2.$

Hence, the surface area is

$SA=2\cdot 9\sqrt{3}+3\cdot 60=180+18\sqrt{3}\ in^2.$
