Whenever we have the root of a negative number, we use the imaginary number 'i' to write it in an easier form.

For example:

Therefore:

The price elasticity of the demand function as a function of p is C. E(p)= p/200-p

It should be noted that the price elasticity of demand simply means the ratio of the percentage change in quantity demanded to the percentage change in price.

In this case, the function is given as:

q = D(p) = 600-3p

Differentiate with respect to p

D'(p) = 3

The elasticity of demand will be:

= (P / 600 - 3p) × (-3)

= P / (200 - P)

In conclusion, the correct option is C.

Tommie will make $12.65 per hour after his raise.

We will perform addition of value equal to mentioned percentage. So, representing this as equation -

Amount of money earned after raise = 11.5 + 10%×11.5

Converting percentage to whole number

Amount of money earned after raise = 11.5 + (10/100×11.5)

Performing multiplication and division on Right Hand Side of the equation

Rajan must climb down 25 ft to return to the bottom of the climbing wall

Height climbed from the bottom of the wall = 15ft

Height: The measurement of an object's height from the base to the top is known as height. It is sometimes referred to as altitude in geometry. The vertical distance between the lowest and highest point is measured. In coordinate geometry, it is often the measurement along the y-axis of an object.

Additional height climbed = 10ft

The probability that at most 3 of light bulbs will be defective will be 0.998.

Probability may be defined as an expression which may be used to determine the possibility of occurring of any event. The probability of happening an event surely is 1 and probability of not happening an event is zero. Since, 5 percent of bulbs are defective then

5% = 0.05 Now,

Non defective bulbs = 1 - 0.05 = 0.95

n = number of light bulbs = 7

We can calculate this using binomial distribution.

p(x) = ⁿCₓ × (pˣ)(1-p) ^n-x

Our question says at most 3 is defective, so it will be

(⁷C₀ × 0.05⁰ × 0.95⁷) + (⁷C₁ × 0.05¹ × 0.95⁶) + (⁷C₂ × 0.05² × 0.95⁵) + (⁷C₃ × 0.05³ × 0.95⁴)

= 0.698 + 0.257 + 0.040 + 0.003

D; Both statements are correct

Here, we want to check the correct statement

Basically from the diagram, it is confirmed that what we have is a 30-60-90 triangle

Now, for a 30-60-90 degrees triangle, the side lengths are in a particular ratio

From the diagram, MO faces the right angle and thus, it is the longest side and the hypotenuse

Now, let us take a look at the ratio of the sides in both submissions

For a 30-60-90 degrees triangle, the ratio of the sides is;

Hence, one side must be twice the length of the other

From Kellie's statement we can see MO is twice NO

From Eddie's statement, we can also see that MO is twice NO

Lastly, we can also see in both that dividing MN by NO yields the root of 3 in both statemets which confirms the existence of the theoretical ratio

So the conclusion here is that;

Both students are correct

We are given a rectangle ABCD

Recall that a rectangle is a quadrilateral in which all angles are right angles (90°)

Each pair of interior angles are supplementary. The two right angles add to a straight angle which means that the opposite sides of a rectangle are parallel.

In quadrilateral ABCD, if m∠A = m∠B = m∠C = m∠D = 90° then AB || DC and AD || BC

Hence, a rectangle is also a parallelogram.

Option B is the correct answer.

The solution to the inequality includes those points, and also the points for which y is greater than -4x.

Thus, the solution to this inequality consists of all the points on that line (solid line) and the whole region above that line:

The ratio of time spent studying math to studying English is 7:2.

According to the question,

We have the following information:

One spends 1 hour a week to study English and 3.5 hours to study math.

Now, we know that the ratio can be simply understood as the division.

So, we will divide the number of hours devoted to math by the number of hours devoted to English.

Ratio of time spent studying math to studying English = 3.5/1

Ratio of time spent studying math to studying English = 35/10

(Now, we will convert this fraction into the simplest form by dividing both the numerator and denominator of the fraction by 5.)

Ratio of time spent studying math to studying English = 7/2

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

12x-6 = 90 because opposite angles are equal if intercepted in parallel lines

12x=96

x= 8

Step-by-step explanation:

if I understand you correctly, then you got

sin(60°) = sqrt(3/2)

and now we have to find cos(60°) based on that.

but : sin(60°) = sqrt(3/4) = sqrt(3)/2

I will continue with that.

one major observation with the trigonometric functions in a norm circle (radius = 1) is that sine and cosine are the legs of a right-angled triangle.

the radius at the angle is the Hypotenuse.

and so, Pythagoras applies

c² = a² + b²

c is the Hypotenuse, a and b are the legs.

so,

radius² = sin²(x) + cos²(x)

and because radius = 1

1² = 1 = sin²(x) + cos²(x)

in our case

1 = sin²(60) + cos²(60)

1 = (sqrt(3)/2)² + cos²(60) = 3/4 + cos²(60)

cos²(60) = 1 - 3/4 = 1/4

cos(60) = sqrt(1/4) = 1/2

Let t be the time in hours it takes a block of ice to melt at T degrees.

Since both variables have an inverse relation, we can say that:

Where alpha is a constant value.

Since we know that a block of ice melts in 2.5 hours when the temperature is 54 degrees, we can plug in such data and find alpha as following:

Therefore, our expression would be:

For T = 45,

We can conclude that it would take 3 hours for the block of ice to melt.

10. |x - 4| - 4 = 1/2x

⇒ Multiplying by 2,

2 |x - 4| - 8 = x

So, x - 4 = (x + 8)/2

             = -(x + 8)/2

When,

x - 4 = (x + 8)/2

2x - 8 = x + 8 (Multiplying by 2)

2x - x = 8 + 8 (Adding 8 and subtracting x to both sides)

x = 16

When,

x - 4 = - (x + 8)/2

2x - 8 = -x - 8 (Multiplying by 2)

2x + x = -8 + 8 (Adding 8 and x to both sides)

3x = 0

x = 0

Hence, the solution is x = 16 and x = 0.

13. (3/4)x = 2x - 10

⇒ Subtract 2x from both sides.

-5x/4 = -10

Multiply both sides by 4/(-5).

(-5x/4)×4/(-5) = -10 × 4/(-5).

x = 8 is the solution of the equation.

15. x² - 7x - 8 > 0

⇒ Solve the quadratic equation by splitting the middle term,

x² - 8x + x - 8 > 0

x(x - 8) + 1(x -8) > 0

(x + 1)(x- 8) > 0

-1 and 8 are the critical points of the inequality.

x < -1 and x > 8 are the solutions of the inequality which are represented by the shaded red region in the graph.

16. x - 5 > - 2x + 4

⇒ Adding 2x to both sides.

3x - 5 > 4

Adding 5 to both sides.

3x > 9

Divide both sides by 3.

x > 3 is the required solution represented by blue shade region in the graph.
