Answer:

1/4

Step-by-step explanation:

When converting radical expressions to rational exponents the exponent on the radicand (1) becomes the numerator of the rational exponent, and the index/root of the radical (4) becomes the denominator of the rational exponent. (1/4)

Answer:  see proof below

Step-by-step explanation:

Given: A + B + C = π                →      A + B = π - C

                                                         A + C = π - B

                                                         B + C = π - A

Cofunction Identities:       sin [(π/2) - A] = cos A

                                          cos [(π/2) - A] = sin A

Sum to Product Identity:   sin A - sin B = 2 cos [(A + B)/2] · sin [(A - B)/2]

Pythagorean Identity:       cos²A + sin²A = 1    →   cos²A = 1 - sin²A

Even/Odd Identity:           cos (-A) = -cos(A)

Double Angle Identity:     cos (2A) = 2 cos²A - 1

Proof LHS → RHS:

LHS:                      cos [(B + C) - A] - cos [(A + C) - B] + cos [(A + B) + C]

Given:                   cos [(π - A) - A] - cos [(π - B) - B]  + cos [(π - C) - C]

                         =  cos (π -2A) - cos (π -2B) + cos (π -2C)

Cofunction:          cos (-2A)  - cos (-2B) + cos (-2C)

Even/Odd:            -cos (2A) + cos (2B) - cos (2C)

Double Angle:     -(2cos²A - 1) + cos (2B) - cos (2C)

                           = 1 - 2cos²A + cos (2B) - cos (2C)

Sum to Product:    1 - 2cos²A - 2sin(B+C) · sin (B-C)

Given:                     1 - 2cos²A - 2sin (π - A) · sin (B - C)

Cofunction:             1 - 2cos²A - 2sin A · sin (B - C)

Pythagorean:         1 - 2(1 - sin²A) - 2sin A · sin (B - C)

                            = 1 - 2 + 2sin²A - 2sin A · sin (B - C)

                            =     -1 + 2sin²A - 2sin A · sin (B - C)

Factor:                        -1 + 2sin A (sin A - sin (B - C))

Given:                     -1 + 2sin A [sin (π - (B + C)) - sin (B - C)]    

Cofunction:             -1 + 2sin A [sin (B + C) - sin (B - C)]  

Sum to Product:      -1 + 2sin A [2 cos B · sin C]  

                               = -1 + 4sin A · cos B · sin C

LHS = RHS  [tex]\checkmark[/tex]

Step-by-step explanation:

Answer:

C. Natural Numbers

Step-by-step explanation:

Before we determine what groups [tex]\sqrt{100}[/tex] fits into, we must simplify it.  We get the number 10, which is much easier to categorize.  Out of the four options, the natural numbers are the smallest group, containing only the numbers we use to count (i.e. 1, 2, 3, 4 ...).  We know that 10 fits into this category because 10 is a non-zero whole number.  Since the natural numbers contain 10 and are the smallest subset, the answer is C.

As a note: 10 will also fit into the whole numbers and rational numbers since all natural numbers are parts of these two groups as well.  These groups contain more numbers, however, making them larger than the natural number set so we can eliminate them.  10 is also not an irrational number since we can accurately define it with a fraction.

The required solution to the given inequality is x > 16, as shown in the graph.

In mathematics, an inequality is a statement that two values or expressions are not equal. An inequality uses one of the comparison symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to). For example, "x + 3 < 10" is an inequality that states that the value of x plus 3 is less than 10.

Here,
As mentioned in the question,
To graph, the solution of the inequality (x+8) > 2 (2.0 + 10).

Simplifying the given inequality:
(x+8) > 2 (2.0 + 10)

x+ 8 > 2(12)
x > 24 - 8
x > 16

Thus, the required solution to the given inequality is x > 16.

Answer:

330

Step-by-step explanation:

heart = 110, and the problem is asking the value of 3 hearts. 3 x 110 = 330

Answer:

d: 330

Step-by-step explanation:

spade  = heart*2

spade-heart = 110

substitute spade into spade:

2*heart-heart = 110

heart = 110

So,

heart = 110

and,

spade = 2*heart = 2*110 = 220

so spade+heart = 220 + 110 = 330

the radius is approximately 6 meters,

height is approximately 11 meters

The radius of cylinder = 6 meter.

The height of cylinder = 11 meter.

A cylinder is a "three-dimensional object with two round flat bases and one curved side. It has a curved surface in the middle. The base and the top surface are identical".

According to the question,

Surface area of the cylinder = 640.56 m²

Let the height of the cylinder = x meters

Let the radius of the cylinder = (x-5)meters

Formula for surface area of cylinder = 2πrh ( where 'r' is the radius of the cylinder and 'h' height of the cylinder)

640.56 = 2(3.14)(x-5)(x)

640.56/(6.28) = x² - 5x

x² - 5x =102

x² - 5x - 102 =0

using quadratic equation, [-b±√(b² - 4ac)]/2a.

b = -5; a=1; c=102

x =[-(-5) ±√(-5)² - 4(1)(102)]/2

 = [5 ± √433]/2

x = 11 and -7

since x=-7 neglect negative value, we get x=11.

The height of the cylinder is 11 meters

The radius of the cylinder is  (11 - 5) = 6 meters.

Hence, The radius of cylinder = 6 meter.

The height of cylinder = 11 meter.

Answer: ss*$7.50 + aa*$11 ≥ $990.

Step-by-step explanation:

We have two variables:

aa = # of adult tickets sold.

ss = # of student tickets sold.

The total profit is:

P = ss*$7.50 + aa*$11

And we want P ≥ $990.

Then we can write the inequality:

ss*$7.50 + aa*$11 ≥ $990.

Now, we have only one equation and two variables, so there are a lot of possible solutions for this system.

[tex]f(2)=3^{2}=9\\\\g(2)=2(2)+5=9\\\\\implies f(x)=g(x)[/tex]

[tex]f(-3)=3^{-3}=\dfrac{1}{27}\\\\g(-3)=2(-3)+5=-1\\\\\implies f(x) > g(x)[/tex]

[tex]f(-4)=3^{-4}=\dfrac{1}{81}\\\\g(-4)=2(-4)+5=-3\\\\\implies f(x) > g(x)[/tex]

Step-by-step explanation:

Let g represent the number of gloves purchased and h represent the number of hats purchased.

The gloves cost $12 and a hat costs $8

We need to write an inequality that represents this situation.

Cost of gloves = $12g

Cost of hats = $8h

No more than $56 means [tex]\le 56[/tex].

We can write the inequality as follows :

[tex]12g+8h\le 56[/tex]

Hence, this is the required solution.

(a) ∠ORP and ∠ORN are a linear pair .

Let us prove that option a , is the correct option by finding the value of x .

Angle ORP and angle ORN are a linear , which means their sum will be equal to 180° .

So :-

[tex]80 + 3x + 10 = 180[/tex]

[tex]3x + 80 + 10 = 180[/tex]

[tex]3x + 90 = 180[/tex]

[tex]3x = 180 - 90[/tex]

[tex]3x = 90[/tex]

[tex]x = \frac{90}{3} [/tex]

[tex]x = 30°[/tex]

As we were able to find put the value of x only after we cam to know that ∠ORP and ∠ORN are a linear pair , we say that option a is the correct statement .

Therefore , the correct answer is :-

(a) ∠ORP and ∠ORN are a linear pair .

The value of x is equal to 30°. Hence, proved.

Angles on a straight line relate to the sum of angles that can be arranged together so that they form a straight line. Angles on a straight line add to 180°.

Given that, m∠ORP=80° and m∠ORN=(3x+10)°.

Here, m∠ORP+m∠ORN=180° (Angles on straight line adds upto 180°)

80°+(3x+10)°=180°

90°+3x=180°

3x=90°

x=90°/3

x=30°

Hence, proved.
