t the season. Each year, he has increased his fee by the same amount. The table shows what Elliot charged each customer for two given years of his business:
Year Lawn Care Fee

2000 $750

2010 $1350



A. What is the rate of change and initial value for Elliot’s business? How do you know?

B. Write an equation in slope-intercept form to represent the fees that Elliot charges each year.

Answer:

A: initial value: $750; rare of change: $60

B: y = 60t + 750

Step-by-step explanation:

Initial value = value when he started ( in 2000) =$ 750

Each year he add a constants to that value

'y' will be the amount he get after t years a amount increase each year

y = 750 + at

In 2010 his free = 1350

t = 2010 - 2000 = 10 year

y = 1350

y = 750 + at

1350 = 750 + 10 a

600 = 10a

a = 60

y = 750 + 60t ( his fee as a function of time)

In slope form: y = 60t + 750

He increases he fee by $60 a year.

EXAMPLE 5 If F(x, y, z) = 4y2i + (8xy + 4e4z)j + 16ye4zk, find a function f such that ∇f = F. SOLUTION If there is such a functi
Valentin [98]

If there is such a scalar function <em>f</em>, then

\dfrac{\partial f}{\partial x}=4y^2

\dfrac{\partial f}{\partial y}=8xy+4e^{4z}

\dfrac{\partial f}{\partial z}=16ye^{4z}

Integrate both sides of the first equation with respect to <em>x</em> :

f(x,y,z)=4xy^2+g(y,z)

Differentiate both sides with respect to <em>y</em> :

\dfrac{\partial f}{\partial y}=8xy+4e^{4z}=8xy+\dfrac{\partial g}{\partial y}

\implies\dfrac{\partial g}{\partial y}=4e^{4z}

Integrate both sides with respect to <em>y</em> :

g(y,z)=4ye^{4z}+h(z)

Plug this into the equation above with <em>f</em> , then differentiate both sides with respect to <em>z</em> :

f(x,y,z)=4xy^2+4ye^{4z}+h(z)

\dfrac{\partial f}{\partial z}=16ye^{4z}=16ye^{4z}+\dfrac{\mathrm dh}{\mathrm dz}

\implies\dfrac{\mathrm dh}{\mathrm dz}=0

Integrate both sides with respect to <em>z</em> :

h(z)=C

So we end up with

\boxed{f(x,y,z)=4xy^2+4ye^{4z}+C}

PLEASE HELP!!!! WILL GIVE BRAINLIEST!!!!<br><br><br><br><br><br> Only need 4b and 4c
JulsSmile [24]

ANSWER:

b) No

c) Yes

EXPLANATION:

3 (x+1)=3x+3

b)

3 (-8 + 1) = 3 x -8 + 3

(3 x -8) (3 x +1) = 3 x -8 + 3     (just put left and right sides into calcu separately)

-72 = -21

Both sides are not equal and therefore it isn't a solution.

c)

3 (0.5 + 1) = 3 x 0.5 + 3

(3 x 0.5) (3 x +1) = 3 x 0.5 + 3

4.5 = 4.5

Both sides are equal and thereofre it IS a solution.
