The concert director can choose the new members by holding try outs to take the the possible candidate’s skills, performance and professionalism into consideration to be a part of the large show. Another way is by voting amongst other people in their school to see who the audience would be excited to see preforming in the show.

Answer:

3miles per hour^2

Step-by-step explanation:

given data

initial speed u= 15mph

final speed v=45mph

time taken t= 10 seconds

Step two:

Required

acceleration a=?

applying the first equation of motion

v=u+at

substitute we have

45=15+a*10

45=15+10a

make a subject of the formula

45-15=10a

30=10a

divide both sides by 10

a=30/10

a=3miles per hour^2

Ganezh [65]

Answer:

(a)0.75x+1200=3.50x

(b) $x=436.36\approx 436, Break-Even \:Point$

(d) $x>436.36\approx 436$

It means the store needs to sell more than 436 funnel cakes to make a profit

Step-by-step explanation:

Given the Cost and revenue function of John boy and Mary Ellen's food stand below:

C= 0.75x+1200.

R=3.50x

(a)When Cost = Revenue

Then:

0.75x+1200=3.50x

(b)To solve the equality from part (a) above

0.75x+1200=3.50x

Collect like terms

1200=3.50x-0.75x

1200=2.75x

Divide both sides by 2.75

$x=436.36\approx 436$

When Cost equals revenue, it is the <u>Break-Even Point.</u> It means the food stand will have to sell 436 funnel cakes to break even.

$C(x)$

(d)Solving the inequality

C(x)<R(x)

0.75x + 1200<3.50x

Collect like terms

1200<3.50x-0.75x

1200<2.75x

Divide both sides by 2.75

$436.36$

$x>436.36\approx 436$

It means the store needs to sell more than 436 funnel cakes to make a profit.
