Step-by-step explanation:

Answer:

1 or -0.5±1.9365i

Step-by-step explanation:

We know that [tex]x^{3} - y^{3} = (x-y) ^{3} +3xy(x-y)[/tex]

So plug in x=a and y=1/a, (a-1/a)^3+3*a*1/a*(a-1/a)=4

Let a-1/a=k, k^3+3k=4, k=1 or a complex conjugate -0.5±1.9365i

That's the answer.

To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.

[tex]5x - 4y = -3[/tex]

[tex]5x - 4(3x-5) = -3[/tex]

[tex]5x -12x+20=-3[/tex]

               [tex]-20[/tex]     [tex]-20[/tex]  

_______________

[tex]5x-12x=-23[/tex]

[tex]-7x=-23[/tex]

___    ____

 [tex]-7[/tex]       [tex]-7[/tex]

[tex]x=3.29[/tex] (rounded)

Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.

[tex]y = 3x-5[/tex]

[tex]y = 3(3.29)-5[/tex]

[tex]y = 9.87-5[/tex]

[tex]y = 4.87[/tex]

So, your final answer would be (3.29, 4.87).

Answer:

5.1 x 102 in scientific notation

Step-by-step explanation:

The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease. Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10bStep 1

step1: To find a, take the number and move a decimal place to the right one position.

Original Number: 510

New Number: 5.10

step 2: Now, to find b, count how many places to the right of the decimal.

New Number: 5 . 1 0

Decimal Count:   1 2

Step 3: Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 5.1 (Please notice any zeroes on the end have been removed)

b = 2

Now the whole thing:

5.1 x 102

Step 4:

Check your work:

102 = 100 x 5.1 = 510

Answer:

a.

capacity of car = 14 gallons

consumption of fuel in one day = 0.6 gallons

consumption of fuel in 14 days = 14 x 0.6 = 8.4 gallons

fuel remaining in car = 14 - 8.4 = 5.6 gallons

so they can drive the car without warning.

b.

consumption of fuel in one day = 0.6 gallons

consumption of fuel in 25 days = 25 x 0.6 = 15 gallons

fuel remaining in car = 14 - 15 = -1 gallons

so they can't drive the car without warning.

c.

the expression 14 - 0.6t represents remaining fuel in the vehicle, where t represents number of days.

d.

14 - 0.6t = 1.5

or - 0.6t = 1.5 - 14 = - 12.5

or t = -12.5 / - 0.6

or t = 20.8333 days

so he can drive 20 days without warning.                                                                                         E.

14 - 0.6t < 1.5

or t < 20.8333

here t represents number of days car can drive without warning light.

Step-by-step explanation:

The inequality is  

The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days

14 gallons-1.5 gallons=12.5 gallons  

we know that

If the remaining fuel is greater than  1.5 gallons Diego's father can drive the car without the warning light coming on  

so

Let

x ----> the number of days

 ----> inequality that represent the situation

Solve for x

The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days

y = x + 7

For -1:

y = -1 + 7 = 6

y = 7

(x,y) = ( -1, 7)

For 0:

y = 0+ 7

y= 7

(x,y) = (0,7)

For 2:

y = 2+ 7

y= 9

(x,y) = (2,9)

For 4:

y = 4+ 7

y= 11

(x,y) = (4,11)

State taxes.

According to Urban dot org, school funding is a blend of federal, state, and local dollars.

State taxes are more likely to be correct due to education being the state's responsibility.

If this is incorrect, please, don't refrain to tell me. Thank you.

Answer:

About 31 years

Step-by-step explanation:

Given data

Principal= $3500

Rate=  4.75%

Final amount= $15,000

Time=??

The expression for time on compound interest is

Calculate time, solve for t

t = ln(A/P) / r

substitute

Calculate time, solve for t

t = ln(15000/3500) / 0.0475

t= ln(4.2857)/ 0.0475

t= 1.4552/0.0475

t= 30.63 years

Hence it will take about 31 years

Answer:

One of the limitations of using the range is that it is a simple but poor measure of variability. It is very susceptible to poor representation of data spread.  It is used mostly with ordered data or ordinal data.                                          

Step-by-step explanation:

The measure of the range of a set of given data can be established once the difference between the highest and lowest values is known.

The range is simple to use but only considers the smallest and largest data elements in the set without considering the middle values and other values that could influence results if the data spread is to be considered.

Ordinal data aren't numerical data. Examples include Time of day such as morning, noon, night.

Answer:

●3 x^2 - 16 x + 20

in this case you will write -16 as a difference

3 x^2 - 6x - 10 x + 2

●2 x^2 + 25x + 50

write 25 as a sum

2 x^2 + 20x + 5 x + 50

Answer: 26 in.

Step-by-step explanation:

Given

Heights of Poles are [tex]12\ in., 22\ in.[/tex]

distance between them is [tex]x=24\ in.[/tex]

the difference in heights of the pole is [tex]y=22-12=10\ in.[/tex]

From the figure, using Pythagoras theorem, distance L is given by  

[tex]\Rightarrow L^2=y^2+x^2\\\Rightarrow L^2=10^2+24^2\\\Rightarrow L^2=100+576=676\\\Rightarrow L=\sqrt{676}=26\ in.[/tex]

The distance between tops is 26 in.
