Hi there!

I believe your answer is:

V = 8,000

Here’s why:  

⸻⸻⸻⸻

[tex]\boxed{\text{Evaluating...}}\\\\V=s^3\\-----------\\\rightarrow V=(20)^3\\\\\rightarrow V = 20 * 20 * 20 \\\\\rightarrow V = 8,000[/tex]

Hope this helps you. I apologize if it’s incorrect.  

Answer:

As this is a quartic equation, we should expect four roots (although some may end being repeated). Notice also that the equation is symmetrical, which suggests that there might be an element of symmetry in the answer.

First, as this equation is a quadratic in terms of z2 , we can use our formula for finding the roots of a quadratic equation to give the value(s) of z2 . [If you have a problem seeing this, use the substitution y=z2 , and you get a quadratic in y .]

z2=−4±42−4×1×16√2×1=−4±16−64√2

=−4±−48√2=−2±12−−√i=−2±23–√i

=4(−12±3√2)i

=4(cos(2kπ3)+isin(2kπ3)) , where k∈1,2

=4e2kiπ3

As this is the value of z2 , whereas we want z , we need to take the square roots of both sides

z=4–√ekiπ3+nπ , where n∈0,1

=2e(k+3n)iπ3

=2cis((k+3n)iπ3)

As we have two values of k and two values of n , this gives us four solutions.

Writing these angles in terms of degrees, we have: 60, 120, 240 and 300

Evaluating, we end up with the four solutions

z=1±3–√i∪z=−1±3–√i

You can substitute z^2 = x,

Then you get x^2+4x+16=0

Step-by-step explanation:

z=1±3–√i∪z=−1±3–√i

You can substitute z^2 = x,

Then you get x^2+4x+16=0

Then you can use classical x1,2 = (-b +- √[b^2–4ac])/2a

X1,2=(-4+-√[16–16*4])/2

After you solve that you substitute back z^2 = x

[tex]f(x)=\dfrac{4}{5}x-2\\\\\\f(3)=\dfrac{4}{5}\cdot3-2=\dfrac{12}{5}-2=\dfrac{12}{5}-\dfrac{10}{5}=\boxed{\frac{2}{5}}[/tex]

Answer:

QT = 26

Step-by-step explanation:

QT = RT + QR + RS

QR = RS

QT = 14 + 6 + 6

QT = 20 + 6

QT = 26

Answer:

8333.33 minutes or 138. 89 hours

Step-by-step explanation:

Speed = distance/time

time = distance/speed = 5000000 meter/600 meter/minute

                                      = 8333.33 minutes or 138. 89 hours

Answer:

y = 0.524m + b is the answerrrr

Answer:

Let x = amount of water to be added with 0% antifreeze

1 = amount of pure antifreeze at 100%

x+1 = amount of the mixture at 60% antifreeze

Step-by-step explanation:

1= .60x + .60

Subtract .60 from each side:

1-.60 = .60x

.40 = .60x

Divide both sides by .60

Check: Total antifreeze = 1 gallon in total mixture of 1 + 2/3 gallon = 5/3 gallons. 1 gallon divided by 5/3 equals 3/5 which is 60%. It checks.

Answer:

8

Step-by-step explanation:

4 + 4 = 8

4 x 2 = 8

hope this helps

Answer:

answer is 8 because 4+4 =8 and 2+2+2+2 =8

8x + 9 = 5x + 6

8x - 5x = 6 - 9

3x = -3 / : 3

x = -1 ← the end answer

Answer:

1

Step-by-step explanation:

x+y = 5

Put this equation in slope intercept form y = mx+b where m is the slope

y = -x +5

The slope of the line is -1

Perpendicular lines have slopes that multiply to -1

-1 * m = -1

m = 1

The slope of the perpendicular line is 1

180° - 95° = 85°

x = 180° - 85° - 60°

Answer:

x = 6, RS = 30

Step-by-step explanation:

5x + 3x = 48

8x = 48

8x/8 = 48/8

x = 6

RS = 5x

RS = 5(6)

RS = 30

OKAY I WAS STRESSING FOR A QUICK MINUTE THINKING I WAS GETTING SOMETHING WRONG BUT THINK THE ANSWER IS CORRECT

So Cos0= 15/64 (SIMPLIFIED) or in decimal form 0.234375

Step-by-step explanation:

7/8² is 49/64 or (in decimal form) 0.765625

1 - 0.765625 = 0.234375

Answer:

18....I hope thats righ

Step-by-step explanation:

Answer:x=5,2/3

Step-by-step explanation:

-b plus over minus square root over b squared -4(ac)/2a

17 plus over minus square root (-17) squared -4 x (3 x10)/2 x 3

x= 17 plus minus 13/6

x=5,2/3

Answer:

45 - (6 x 5) = t

Step-by-step explanation:

please mark brainliest

Answer:

45=6(5)+t

$15

Step-by-step explanation:

The equation used to describe this situation would be y=6x+t, where y is the total amount Jonny made, x is the number of hours worked, and t is the total tips. The problem tells us that Jonny made $45 total and worked for 5 hours. So, to solve plug these numbers in and solve for t. The number equation looks like, 45=6(5)+t.

Then, to solve first distribute the 6.

45=30+t

Next, subtract 30 from both sides

15=t

That is your final answer, Jonny made $15 in tips.
