Find w = a + bi = [tex]\sqrt{z}[/tex] where a and b are real numbers.
[tex]\sqrt{-7-24i}[/tex]

Answer:

B

Step-by-step explanation:

We have the function:

[tex]f(x)=x^2-5x[/tex]

And we are given that:

[tex]f(n)=-4[/tex]

And we want to find the value of n such that this is true.

So, let's substitute f(x) for -4 and x for n. This yields:

[tex]-4=n^2-5n[/tex]

Let's solve for n. First, add 4 to both sides:

[tex]n^2-5n+4=0[/tex]

This is a quadratic. We can solve by factoring:

[tex](n-1)(n-4)=0[/tex]

Zero Product Property:

[tex]n-1=0\text{ or } n-4=0[/tex]

Solve for n for each equation:

[tex]n=1\text{ or }n=4[/tex]

So, n can be either 1 or 4.

Our of our answer choices, the correct answer is B.

And we're done!

Answer:450

Step-by-step explanation:i think 452 rounded to the nearest ten is 450 is because one you should look at the tens place then after you can tell is because 0-5 round down and any number higher like 5-9 you round up.

Answer:

450

Step-by-step explanation:

50 is the closest ten to 52.

Remember:

4 and under is rounded to the ten that's lesser than the other.

5 and up is rounded to the ten that's more than the other.

Example: Your number is 74. Because it's a 4 and under number, it would be rounded to 70.

Example 2: Your number is 47. Because it's a 5 and up number, it would be rounded to 50.

Answer:

2B/( h-q)=a

Step-by-step explanation:

2B=ha-qa

Factor out an a

2B=a(h-q)

Divide each side by ( h-q)

2B/( h-q)=a(h-q)/( h-q)

2B/( h-q)=a

Answer:

a = [tex]\frac{2B}{h-q}[/tex]

Step-by-step explanation:

Given

2B = ha - qa ← factor out a from each term

2B = a(h - q) ← divide both sides by (h - q)

[tex]\frac{2B}{h-q}[/tex] = a

[tex]d=10.8[/tex]

Step-by-step explanation:

Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d=\sqrt{(6-(-3))^2+(-3-3)^2}[/tex]

[tex]d=\sqrt{(6+3)^2+(-6)^2}[/tex]

[tex]d=\sqrt{(9)^2+36}[/tex]

[tex]d=\sqrt{81+36}[/tex]

[tex]d=\sqrt{117}[/tex]

[tex]d=3\sqrt{13}[/tex]

[tex]d=10.8167[/tex]

[tex]d=10.8[/tex]

Answer:

3 ways

Step-by-step explanation:

From the question:

Number of acres of the land = 100 acres

1 cow = 10 acres of land

1 sheep = 3 acres of land

To fully utilize the land, the number of ways to stock the ranch so that it includes at least one cow and at least one sheep is calculated as:

1) 1 cow and 30 sheep

1 cow × 10 acres + 30 sheep × 3 acres

10 + 90 = 100 acres

2) 4 cows and 20 sheep

4 cow × 10 acres + 20 sheep × 3 acres

40 + 60 = 100 acres

3) 7 cows and 10 sheep

7 cow × 10 acres + 10 sheep × 3 acres

70 + 30 = 100 acres

Therefore, to fully utilize the land, the number of ways to stock the ranch so that it includes at least one cow and at least one sheep is 3 ways

Hey there!

The equation of a st.line passing through points (6,-5) and (3,0) is;

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]

[Using double point formula]

Now, Put all values,

[tex](y + 5) = \frac{0 + 5}{3 - 6} (x - 6)[/tex]

Simplify it to get equation.

[tex](y + 5) = - \frac{5}{3} (x - 6)[/tex]

[tex]3(y + 5) = - 5(x - 6)[/tex]

[tex]3y + 15 = - 5x + 30[/tex]

[tex]5x + 3y + 15 - 30 = 0[/tex]

[tex]5x + 3y - 15 = 0[/tex]

Therefore the required equation is 5x + 3y - 15 = 0.

Answer:

y = -5/3x + 5

Step-by-step explanation:

The formula for the equation of a line is :

y - y1 = m (x-x1)

m is the gradient

formula

[tex]\frac{y2-y1}{x2-x1} \\\\[/tex]

= (0--5)/ (3-6)

=5 / -3

gradient = - 5/3

y - y1 = m (x-x1)

y - -5 = -5/3 (x - 6 )

y + 5 = -5/3 x + 10

y = -5/3x + 10 - 5

y = -5/3x + 5

Answer:

third one

Step-by-step explanation:

Answer:

m=slope

y= intercept

m=y2-y1 /x2-x1     -8  - 6= -14

                              4- -3 =   7

                                        -14/7 a 2 is your slope

y=2x=b

Now we find for X

choose a y from one of your points :  lets use 6 Plug 6 in for y s(-3,6)

y=2x+b

6=2(-3) +b

now solve for b

6= -6 + b  

now add 6 to both sides to get b alone

6+6 =6+-6 +b

12=b

now write you equation out  y=2x =12

Answer:

As a proper fraction. (numerator smaller than denominator): 2/3 = 2/3

As a decimal number: 2/3 ≈ 0.67.

As a percentage: 2/3 ≈ 66.67%

That's all I can provide

The value of the expression (-64)^(2/3) can be simplified as 16.

Given an expression (-64)^(2/3).

We have to find the value of the expression.

We have the rules of exponents that,

aᵇⁿ = (aᵇ)ⁿ

Using this rule, the expression can be written as,

(-64)^(2/3) = (-64²)^(1/3)

                 = (4096)^(1/3)

Now,

(a)^(1/3) is equal to ∛a.

(-64)^(2/3) = ∛4096

                 = 16

Hence the correct option is B.

Answer:

32 feet of fence

Step-by-step explanation:

The garden is a square, so the length and width are equal.

A = L x W

W = L

A = W²

A = 64

W² = 64

W = √64 = ±8 -- (-8) would be extraneous

W = 8 ft

L = 8ft

Since she is putting the fence around the garden, she needs to find the perimeter.

P = 2L + 2W

P = 2(8) + 2(8)

P = 16 + 16

P = 32 ft

32 feet of fence
