What is the domain of this graph?

A function z=f(x,y) has two partial derivatives and y. These derivatives correspond to each of the independent variables and can be interpreted as instantaneous rates of change (that is, as slopes of a tangent line). Similarly, ∂z/∂y represents the slope of the tangent line parallel to the y-axis.

Answer:

  y = 1000·1.20^x

Step-by-step explanation:

The form of an exponential function is ...

  y = a·b^x

where 'a' is the initial value (y-intercept), and 'b' is the common ratio (growth factor).

The growth factor is related to the growth rate by ...

  growth factor = 1 + growth rate

For a growth rate of 20%, the growth factor is ...

  growth factor = 1 +20% = 1.20

__

The problem statement tells you the initial value is $1000, so your exponential function is ...

  y = 1000·1.20^x . . . . . x is the number of years after the current year; y is the watch value in dollars

Answer:

t = 4

Step-by-step explanation:

given x varies inversely as t , then the equation relating them is

x = [tex]\frac{k}{t}[/tex]  ← k is the constant of variation

To find k use the condition x = 8 when t = 6 , then

8 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )

48 = k

x = [tex]\frac{48}{t}[/tex] ← equation of variation

when x = 12 , then

12 = [tex]\frac{48}{t}[/tex] ( multiply both sides by t )

12t = 48 ( divide both sides by 12 )

t = 4

Answer:

Step-by-step explanation:

You just look at how far shifted to the left or right it is

Step-by-step explanation:

there are 12 months in a year, and therefore 2×12 = 24 "half-months" and therefore semimonthly payments.

that means each paycheck is

72,000 / 24 = $3,000

there are 52 weeks per year.

that means they're are 52/2 = 26 biweekly periods and therefore payments.

each paycheck is therefore

72,000 / 26 = $2,769.23

so, Alice receives 2 more paychecks (26 to 24) in a year.

the difference between the 2 types of payment is

3000 - 2769.23 = $230.77

[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{6})\qquad (\stackrel{x_2}{-3}~,~\stackrel{y_2}{4}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{4}-\stackrel{y1}{6}}}{\underset{run} {\underset{x_2}{-3}-\underset{x_1}{2}}}\implies \cfrac{-2}{-5}\implies \cfrac{2}{5}[/tex]

Answer/Step-by-step explanation:

For the one on the left, the domain is (-∞,-1)∪[0,0]∪(1,3]

Remember that the domain is what values x are. If the dot is solid, use a bracket, if it is empty, use parentheses.

The range is [-3,-3]∪[-1,-1]∪(2,4]

The equation is a piece-wise function.

When x>-1    f(x)=-3

When x=0    f(x)=-1

When 1<x≤2   f(x)=2x

The percentage of the model is shaded is 45% if the total number of square is 80 option (H) is correct.

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

Total number of squares = 10×8 = 80

Total number of squares shaded = 36

Percentage of the model is shaded = (36/80)×100

= 0.45×100

= 45%

Thus, the percentage of the model is shaded is 45% if the total number of square is 80 option (H) is correct.

Answer

7 or 4

because do you see how v is lined 2 I don't remember if you times or divide .I'm going to go with times.

So what is 2 x 10 since V=10

2 x 10=20

Then we are going to divide so what is 20 divided by 5 since e=5

20 divided by 5=4

Next our last step what is 4 + 3=7 and there's are answer.

The answer is divide then this would be the answer.

so V(10) divided by 2=5  divided by e(5) =1 + 3=4

Answer:

y = -2x + 8

Step-by-step explanation:

Solve for y

y + 2 = -2(x - 5)

y + 2 = -2x + 10

y = -2x + 8

y = -2x + 8

Slope-int. form is written as y=mx+b

m is your slope and b is you y intercept

You first will evaluate the -2(x-5) to get:

-2x + 10

Then you'll subtract 2 from each side to get the y alone:

y = -2x + 8

Answer:

48$  and -110.842%

Step-by-step explanation:

A=48$

It=48$ because your paying 2$ for 2 years so 1 year=12 months so 2$=1 month so in 12 months he gets 24$ and then for another year he get's another 24$

24 + 24=48$.

B= -110.842%

it= -110.842.

Answer: QE = 10

Step-by-step explanation: To solve this problem, it's important to understand that the diagonals of a parallelogram bisect each other.

This means that E is the midpoint of diagonal SQ.

So we can setup the equation x² + 9x = 4x + 6.

To solve this polynomial equation, set it equal to zero first.

So we have x² + 5x - 6 = 0 and we get (x + 6)(x - 1) = 0

when we factor the left side of the equation.

So this means that x = -6 or x = 1.

However, -6 will give us a negative length when we plug it in

to find QE so this will not work.

However, plugging 1 in will give us 10 as a length so QE = 10.

Answer:

Thus Volume of pool is [tex]297.67m^{3}[/tex]

GIVEN: A swimming pool 20.6 m long 8.5 m wide and height 1.7 m

TO FIND: Volume of water needed to fill it.

SOLUTION:

Length = 20.6 m

Width = 8.5 m

Height = 1.7 m

Volume = L × B × H

→ [tex]1.7\times20.6\times8.5[/tex]

→ [tex]297.67m^{3}[/tex]

Thus volume of pool is [tex]297.67m^{3}[/tex]

Answer:

Multiply 0.25x by 8

Step-by-step explanation:

82.5 + 8(0.25x) = 338.5

Multiply 0.25x by 8 we get,

8 × 0.25x = 2x

Thus, 82.5 + 2x = 338.5

-TheUnknownScientist 72

Commutative property states out that in multiplication, changing the order of the numbers still have the same product (the product remains the same)

So, we can rewrite 8(0.25x) as (8 x 0.25)x = 2x

So, 82.5 + 8(0.25x) = 82.5 + 2x

Step-by-step explanation:

Frequency tables are used to represent datasets and their frequencies

The average number of miles he drove per month is 1358.3 miles

From the frequency table, the total number of miles travelled in a year is:

Total = 16300 miles

There are 12 months in a year.

So, the average number of miles is:

[tex]Average = \frac{16300}{12}[/tex]

Divide

[tex]Average = 1358.3[/tex]

Hence, the average number of miles he drove per month is 1358.3 miles
