6. The revenue function for a production by a theatre group is

Sidana [21]

Answer:

When the ticket price is $3 or $4 the production will be in break even

Step-by-step explanation:

<u><em>The correct question is</em></u>

The revenue function for a production by a theatre group is R(t) = -50t^2 + 300t where t is the ticket price in dollars. The cost function for the production is C(t) = 600-50t. Determine the ticket price that will allow the production to break even

we know that

Break even is when the profit is equal to zero

That means

The cost is equal to the revenue

we have

$R(t)=-50t^2+300t$

$C(x)=600-50t$

Equate the cost and the revenue

$-50t^2+300t=600-50t$

solve for t

$-50t^2+300t+50t-600=0$

$-50t^2+350t-600=0$

Solve the quadratic equation by graphing

using a graphing tool

the solution is t=3 and t=4

see the attached figure

therefore

When the ticket price is $3 or $4 the production will be in break even

Carlos started at sea level, climbed a cliff to a height of 14 m, then dived 19 m. Find the level at which his dive ended.

Sidana [21]

He started at 0, then he went up to a elevation of 14 m, then went down to 19m so it is 14-19 which =

-5 meters

Please help- I don't know math very well :(

Vanyuwa [196]

#1

$\\ \sf\longmapsto f(x)=4(x-3)$

$\\ \sf\longmapsto f(3)$

$\\ \sf\longmapsto 4(3-3)$

$\\ \sf\longmapsto 4(0)$

$\\ \sf\longmapsto 0$

#2

Here

a_n=7n

$\\ \sf\longmapsto a_{10}=7(10)=70$

#3

d=1/4

a=1/4

$\\ \sf\longmapsto a_4=a+(n-1)d$

$\\ \sf\longmapsto a_4=\dfrac{1}{4}+(3)(\dfrac{1}{4})$

$\\ \sf\longmapsto a_4=1$

#4

$\\ \sf\longmapsto y=2x-8$

$\\ \sf\longmapsto 2x=y+8$

$\\ \sf\longmapsto f(x)=\dfrac{8+y}{2}$

#5

$\\ \sf\longmapsto a_n=n-1$

$\\ \sf\longmapsto 4.5- 4(0.5)$

$\\ \sf\longmapsto 4.5-2$

$\\ \sf\longmapsto 2.5$

You are watering a garden. The height $h$ (in feet) of water spraying from the garden hose can be modeled by $h\left(x\right)=-0

Vladimir79 [104]

Answer:

$h(x+1)=-0.1x^2+0.5x+3.6$

Step-by-step explanation:

The equation is $h(x)=-0.1x^2+0.7x+3$

Where h(x) is the height and x is the distance from where you are standing

The new distance is "1 foot farther from where you are standing" -- so this affects x, which becomes "x+1".

We simply replace x with x +1 in the equation of h(x) and simplify if possible:

$h(x)=-0.1(x+1)^2+0.7(x+1)+3\\h(x)=-0.1(x^2+2x+1)+0.7x+0.7+3\\h(x)=-0.1x^2-0.2x-0.1+0.7x+3.7\\h(x)=-0.1x^2+0.5x+3.6$

THis is the new function.
