If N(k) is the inverse of K(n) and N(12) = 4, then K(4) = 12

Answer:

Step-by-step explanation:

Step(i):-

Given equation is sin x cos x = -1/4

                           [tex]2(2sinxcosx) = -1[/tex]

we know that trigonometry formula

                             2 sin x  cos x = sin 2x

                            2 ( sin 2 x) = -1

                                sin2x = -1/2

Step(ii):-

                            sin2x =    [tex]\frac{-1}{2} = sin (\pi +\frac{\pi}{6}[/tex]

πAnswer:

Therefore, the area of a sector of a circle would be 13.5π square units.              

Step-by-step explanation:

Given

The area of a sector of a circle is:

A = π r² Ф/360

A = π (9)² 60/360

A = π 81 * 1/6

A = 13.5π square units

Therefore, the area of a sector of a circle would be 13.5π square units.

Answer:

16.78%

Step-by-step explanation:

Total = men+women

= 362+73 = 435

Percentage: 73/435 × 100

= 16.78%

Answer:

20%

Step-by-step explanation:

Use 362 as 100% since it is the output value and use 73 as a x value then put them into the equation 100%/x% = 362/73 then flip the equation x%/100% = 73/362

Answer: C=2πr

r Radius

Answer: 16. C  17. A  18. A  

19  You got this! There is only one answer with the correct radius squared!

Step-by-step explanation:

For the coordinates of the center, flip the signs in the parentheses.

For the "=output": in the equation, square the given radius.

Center: (-14.4) the signs in (x + 14)²+(y - 4)² are the opposites.

Radius given: 2  Square it to get the =4

Answer:

0.01

Step-by-step explanation:

Using the z score formula

z = (x-μ)/σ,

where x is the raw score = 135

μ is the population mean = 100

σ is the population standard deviation = 15

z = 135 - 100/15

z = 2.33333

P-value from Z-Table:

P(x<135) = 0.99018

P(x>135) = 1 - P(x<135)

P(x > 135) = 1 - 0.99018

= 0.0098153

Approximately to 2 decimal places

= 0.01

Therefore, the proportion of the population for the following IQ score of 135 is 0.01

Answer:

2x + 2y ≤ 20

x + 3y ≤ 2

Step-by-step explanation:

this is the correct answer i got on my assignment-------

The system of inequalities can model Gabrielle’s situation is x + 2y ≤ 20

and 3x + 2y ≤ 21.

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.

It follows from the task content, that the inequalities which can be used to model Gabrielle's situation be determined.

By setting variables as follows; batches of brownies = x and batches of cookies = y

Brownie:

Sugar = 1 cup

Eggs = 2

x + 2y ≤ 20

Cookie:

Sugar = 3 cups

Eggs = 2

3x + 2y ≤ 21

Gabrielle has 20 eggs and 21 cups of sugar, and she would like to know how many batches of brownies and cookies she can bake without getting more of these ingredients. Part A Question Which system of inequalities can model Gabrielle’s situation, where x represents batches of brownies and y represents batches of cookies?

Answer:

I think 5.4

Step-by-step explanation:

Take it and divide by the number of sides

The Perimeter of rectangle is 27.4 m

The area of rectangle is product of its length to tis width.

So, Area of rectangle = length  x width

Given:

Area of the flower bed = 20.4 square meters.

length = 12 m

As a rectangle, its area be

A = l x w

20.4 = 12 w

w= 20.4/ 12

w= 1.7

Now, Perimeter of rectangle

= 2( l + w)

= 2( 12+ 1.7)

= 27.4 m

Hence, the Perimeter of rectangle is 27.4 m

Answer: D) Side-Angle-Side  (SAS)

Check out the diagram below. Note the color coding to see how the angles and sides correspond to the given information. We aren't given RT = RT, but we use the reflexive property in this case. The angles are between the sides so we use SAS.

We don't have enough information to determine anything about the other angles, so we cannot use AAS or ASA. Also, recall that SSA is not a valid congruence theorem. Luckily the angle is between the sides so we don't have to worry about SSA.

Answer:

1.25

Step-by-step explanation:

if you paid 7.50 for 6 feet of rope we can figure out how much each foot of rope is by example 750 divided by 6 which equals 1.25 .

Answer:

$62.50

Step-by-step explanation:

Proportions:

$7.50 ⇔ 6ft
