Answer:

f = 1/18ir^3

Step-by-step explanation:

Let's solve for f.

3r2ifr=1/6

Step 1: Divide both sides by 3ir^3.

3fir3/3ir3 =1/6/3ir3

f=1/18ir3

Answer:

x^3 - 2x^2 + 9x - 18.

Step-by-step explanation:

The complex roots occur in conjugate pairs so there are 3 roots 2, 3i and -3i.

So we have:

P(x) = (x - 2)(x - 3i)(x + 3i)

= (x - 2)(x^2 - 9i^2)

= (x - 2)(x^2 - 9*-1)

= (x - 2)(x^2 + 9)

= x^3 + 9x - 2x^2 - 18

= x^3 - 2x^2 + 9x - 18.

Answer:

Value of blank = 1 / (-5x)

Step-by-step explanation:

Given:

__ × (-5x) = 1

Find:

Value of blank

Computation:

Assume;

Blank = y

So,

y × (-5x) = 1

y = 1 / (-5x)

Value of blank = 1 / (-5x)

Answer:

b. no solution

Step-by-step explanation:

change to slope-int form

y=-4x-8

y=-4x+5/2

see how the slopes are the same but the y-int are different? they are parallel, so they never touch

Answer:

x = 6

Step-by-step explanation:

Instructions?  I'm assuming you were asked to "solve for x."

To eliminate fractions, multiply both sides by 4.  This results in x = 6.

The number 0.405 is greater than the number 0.045.

What is Decimal number?

A decimal number is a number that consists of a whole and a fractional part.

Given that;

The numbers are,

⇒ 0.045 and 0.405

Now,

In the numbers,

⇒ 0.045 and 0.405

The place value 4 in the number 0.045 = 4/100

And, The place value 4 in the number 0.450 = 4/10

Thus, The number 0.405 is greater than the number 0.045.

Answer:

85 students

Step-by-step explanation:

If 17 = 20%

It means is the fifth part of 100%

Because 20% * 5 = 100%

With that logic if we multiply the amount of students by 5 we will get the total of students.

17*5= 85

Hope it was helpful ;)

Answer:

A 20% decrease I believe

Step-by-step explanation:

So, you subtract 660-528 which is 132. You then divide that by 660 and you get 0.2 or 20%

The values of x are:

[tex]x=3,\:x=7[/tex]

Step-by-step explanation:

Given the expression

[tex](x-2)^2-6(x-2)+5=0[/tex]

Expand (x - 2)² = x² -4x + 4

[tex]x^2-4x+4-6\left(x-2\right)+5=0[/tex]

Expand: -6(x - 2) = -6x + 12

[tex]x^2-4x+4-6x+12+5=0[/tex]

simplifying

[tex]x^2-10x+21=0[/tex]

Factor  x² -10x + 21:  (x - 3) (x - 7)

[tex]\left(x-3\right)\left(x-7\right)=0[/tex]

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

[tex]x-3=0\quad \mathrm{or}\quad \:x-7=0[/tex]

solving x - 3 = 0

x - 3 = 0

Adding 3 to both sides

[tex]x-3+3=0+3[/tex]

simplify

x = 3

solving x - 7 = 0

x - 7 = 0

Adding 7 to both sides

[tex]x-7+7=0+7[/tex]

Simplify

x = 7

Therefore, the values of x are:

[tex]x=3,\:x=7[/tex]

Answer:

a) 0.0256 = 2.56% probability of 4 heads.

0.1296 = 12.96% probability of 4 tails.

b) The probability is 0.0576 = 5.76%.

c) 6 outcomes given 2 heads in 4 tosses. 0.3456 = 34.56% probability of 2 heads in 4 tosses

Step-by-step explanation:

For each throw, we have these following probabilities:

0.4 = 40% probability of heads.

0.6 = 60% probability of tails.

(a) Compare the probability of 4 heads in 4 tosses and 4 tails in 4 tosses.

4 heads:

4 throws, each with 0.4 probability of heads. So

[tex](0.4)^4 = 0.0256[/tex]

0.0256 = 2.56% probability of 4 heads.

4 tails:

4 throws, each with 0.6 probability of tails. So

[tex](0.6)^4 = 0.1296[/tex]

0.1296 = 12.96% probability of 4 tails.

(b) Determine the probability of H T H T in 4 tosses.

H = 0.4, T = 0.6. So

[tex]p = 0.4*0.6*0.4*0.6 = 0.0576[/tex]

The probability is 0.0576 = 5.76%.

(c) Determine the number of outcomes that give us 2 heads in 4 tosses in any order. What is the probability of 2 heads in 4 tosses (use (b) and the number of outcomes)

Number of outcomes:

The possible outcomes are:

H - H - T - T

H - T - H - T

H - T - T - H

T - H - H - T

T - H - T - H

T - T - H - H

6 outcomes given 2 heads in 4 tosses.

Each with probability 0.0576, as found in b)

6*0.0576 = 0.3456

0.3456 = 34.56% probability of 2 heads in 4 tosses

Answer:

$31.5

Step-by-step explanation:

X * 5% = $1.50

X = $1.50 / 5%

Or by using simple rule of three:

If 5% is $1.50

Then 100% is X

So you obtain = $30

Now you just need to sum The net prices and the taxes

Net + tax = Total Charge

$30 + $1.5 = $31.5
