Step-by-step explanation:

x²=-9-27

x²=-36

there's no x

Answer:

x = ± 6i

Step-by-step explanation:

Given

x² + 27 = - 9 ( subtract 27 from both sides )

x² = - 36 ( negative value indicates the solutions are complex )

Take the square root of both sides

x = ± [tex]\sqrt{-36}[/tex] = ± 6i

73%  of the model is shaded,  146/200 is the equivalent ratio.0.73 is the equivalent decimal and 146/200 is the equivalent fraction

A fraction represents a part of a whole.

Given,

A grid model with 100 squares. 73 squares are shaded.

We need to find percent of the model is shaded

As there are 100 grids with 73 shaded.

73%  of the model is shaded

Now let us find equivalent ratio of 73/100

Multiply numerator and denominator 2

73/100×2/2

146/200

146/200 is the equivalent ratio.

73/100=0.73 is the equivalent decimal.

146/200 is the equivalent fraction.

Hence,73%  of the model is shaded,  146/200 is the equivalent ratio.0.73 is the equivalent decimal and 146/200 is the equivalent fraction.

Answer:

x = 36.27

Step-by-step explanation:

By using the steps to find sin θ backwards, we can find x, the hypotenuse.

sin θ = [tex]\frac{opposite}{hypotenuse}[/tex] or side [tex]\frac{a}{c}[/tex] (as seen in my example picture).

We already know the value for sin (α), which is 32° because its given. The opposite side (a) is 20 and the hypotenuse side (c) is x which are both also given.

So the equation now looks like:

sin 32° = [tex]\frac{20}{x}[/tex]

Don't solve for the sin 32 yet! First, we have to isolate the variable.

To get rid of the x in the denominator you have to multiply both sides by x:

( sin 32 ) · x = ( [tex]\frac{20}{x}[/tex] ) · x

( sin 32 ) x = 20

Then, you have to divide both sides by sin 32 to get x by itself:

(( sin 32 ) x ) ÷ ( sin 32 ) = 20 ÷ ( sin 32 )

x = 20 ÷ ( sin 32 )

Lastly, you have to use a calculator to find 20 ÷ ( sin 32 ), and it should give you 36.2695543766.

The question asks you to round to 2 decimal places so:

x = 36.27

Answer:

x = -4 or y = 7 or f(x) = 7

Answer:

b)15.75 and 2.9432

Step-by-step explanation:

The computation of the mean and the standard deviation is shown below:

The mean of a binomial distribution is:

[tex]\mu[/tex] = np

And the standard deviation is

[tex]\sigma[/tex] =  √(npq)

where,

n = 35,

p = 0.45,

and q = 1 - 045 =  0.55

Now mean is

= 35 × 0.45

= 15.75

And, the standard deviation is  

= √(35 × 0.45 × 0.55)

= 2.9432

Hence, the correct option is B.

Answer:

Step-by-step explanation:

Step one:

given

original price= $60

discount =20% of 60

discount = 20/100*60

discount = 0.2*60

discount = $12

selling price= 60-12= $48

Added price= 10% off $48

Added price= 10/100 *48

Added price= 0.1 *48

Added price= $4.8

new price= 4.8-48=$43.2

the new price of the jacket is $43.2

1. The jacket is now 40% off its original price

40/100*60=$24-----False

2. The jacket now costs $48.00-----False

3.  The jacket is now 72% of its original price= 72/100*60=$43.2----True

4. The jacket now costs $43.20------True

Answer:

Total area of board = 36x² + 324 + 216x

Step-by-step explanation:

Given:

Side of square = x + 3

Total number of square = 6 x 6 = 36

Area of each square = Side x Side

Area of each square = (x + 3)²

Area of each square = x² + 9 + 6x

Total area of board = 36[Area of each square]

Total area of board = 36[x² + 9 + 6x]

Total area of board = 36x² + 324 + 216x
