What will be the cost for 8 hours of work? 10 hours of work?

andreyandreev [35.5K]

Answer:

Cost = 25 + 50h

cost for 8 hours of work = $425

cost for 10 hours of work = $525

Step-by-step explanation:

The question is as following:

A plumber charges $25 for a service call plus $50 per hour of service write an equation to represent the cost of hiring this plumber.

what will be the cost for 8 hours of work? 10 hours of work?

=======================================================

A plumber charges $25 for a service call plus $50 per hour

Cost = 25 + 50h

Where h is the number of hours of service

8 hours of work: h = 8

Substitute with h = 8 at the equation of cost

Cost = 25 + 50* 8 = $425

10 hours of work: h = 10

Substitute with h = 10 at the equation of cost

Cost = 25 + 50 * 10 = $525

HELP ASAP PLEASE!!

Mama L [17]

Answer:

Step-by-step explanation:

According to the table, function g(x) reaches the max height of 33, approx.

The equation of motion is f(x) = -16x^2 + 42x + 12. We need to determine the maximum of this function. To do this, find the x-coordinate of the vertex, which is x = -b/(2a), or x = -42/(2*-16), or 1.31 sec.

Evaluating f(x) = -16x^2 + 42x + 12 at x = 1.31 sec, we get f(1.31) = 39.6.

So it appears that f(x) has a higher max than does g(x); the difference is approx. 39.6 - 33, or 6.6

Wht equation describes a parabola that opens up or down and whos vertex is at the point (h,v)

LUCKY_DIMON [66]

Answer:

$f(x)=a(x-h)^2+k$

Vertex form.

Step-by-step explanation:

You are talking about the vertex form for a parabola.

$f(x)=a(x-h)^2+k$ tells us:

A) The vertex is (h,k).

B) Open up (if a is positive) or open down (if a is negative)

C) a also tells us how much it is vertically stretched or compressed.

The Florida Fish and Wildlife Conversation Commission (FWC) plans to hire hunters to kill the Burmese python, an invasive specie

andrew-mc [135]

Complete Question

The complete question is shown on the first uploaded image

Answer:

FWOC should hire 70,000 hunters to completely remove the python in the area

Step-by-step explanation:

From the question we are given that the Initial Pythons $P_o=$ 100,000

And the final python $P_f$ $=100,000+\frac{P}{10,000}(100,000-P)$

$P_f = 100,000 + 10P -\frac{P^2}{10,000}$

For Max Number of Python

=> $\frac{dP_f}{dP} = 0$

=> $\frac{dP_f}{dP} =$ $100,000 -2P = 0$

=> $P = 50,000$

Hence the maximum number of pythons $Max_P$ $=100,000 +\frac{50,000}{10,000} (50,000)$

$=350,000$

Using Mathematical relations

from the Question

5 python is killed by = 1 hunter

1 python is killed by = $\frac{1}{5} \ hunters$

350 , 000 pythons are killed by = $\frac{350,000}{5}$

$= 70,000 \ hunters$
