The barbers profit p each week depends on his charge c per haircut. It is modeled by the equation p= -200c^2+2400c-4700. What pr
shepuryov [24]

Answer:

0 ≤ c ≤ 12

Step-by-step explanation:

The function can be rearranged to ...

p = 200c(12 -c) -4700

suggesting that revenue will be zero for a charge of 0 or for a charge of 12, and that fixed expenses are 4700. Charges less than 0 are uninteresting, and charges high enough to cause the number of customers to be negative also don't make any sense in this context.

Though out of the range of likely consideration, charges low or high enough to cause profit to be negative (more than 9.54, for example) seemingly can be reasonably modeled by this function.

Coin Toss A coin is tossed upward with an initial velocity of 32 feet per second from a height of 16 feet above the ground.
AleksAgata [21]

Answer:

The object ever reach a height of 32  feet in 1 second

Step-by-step explanation:

The equation giving the object’s height : h = 16 + 32t -16t^2

Where h = object’s height

t = time

We are supposed to find Does the object ever reach a height of 32  feet

Substitute h = 32 in equation

32 = 16 + 32t -16t^2

32-16= 32t -16t^2

16= 32t -16t^2

1=2t-t^2

t^2-2t+1=0

t^2-t-t+1=0

t(t-1)-(t-1)=0

(t-1)(t-1)=0

t=1,1

So, The object ever reach a height of 32  feet in 1 second

Find p and q for which the linear eqn has infinite solutions 6x-(2p-3)y-2q-3=0, 12x-( 2p-1)y-5q+1=0
astra-53 [7]

Answer:

p= 2.5

q= 7

Step-by-step explanation:

The lines should overlap to have infinite solutions, slopes should be same and y-intercepts should be same.

Equations in slope- intercept form:

  • 6x-(2p-3)y-2q-3=0 ⇒ (2p-3)y= 6x -2q-3 ⇒ y= 6/(2p-3)x -(2q+3)/(2p-3)
  • 12x-( 2p-1)y-5q+1=0 ⇒ (2p-1)y= 12x - 5q+1 ⇒  y=12/(2p-1)x - (5q-1)/(2p-1)

<u>Slopes equal:</u>

6/(2p-3)= 12/(2p-1)

6(2p-1)= 12(2p-3)

12p- 6= 24p - 36

12p= 30

p= 30/12

p= 2.5

<u>y-intercepts equal:</u>

(2q+3)/(2p-3)= (5q-1)/(2p-1)

(2q+3)/(2*2.5-3)= (5q-1)/(2*2.5-1)

(2q+3)/2= (5q-1)/4

4(2q+3)= 2(5q-1)

8q+12= 10q- 2

2q= 14

q= 7
