The solution is , f(x) = tan (x) the function is defined at 0≤x<90 is the domain of the function.

Given the function f(x) = tan (x)

From trigonometry identity, tan (x) = sin(x)/cos(x)

f(x) = sin(x)/cos(x)

Using the quotient rule to find the derivative of the function, we will have;

f'(x) = cos (x)cos (x) - sin (x)[-sin (x)]/ cos²x

f'(x) = cos²x - sin²x/ cos²x

Divide through by cos²x

f'(x) = cos²x/cos²x + sin²x/cos²x / cos²x/cos²x

f'(x) = 1 + sin²x/cos²x / 1

f'(x) = 1 + (sin²x/cos²x)

f'(x) = 1 + tan²x

From trig identity,  1 + tan²x = sec²x

Hence, f'(x) = sec²x

Hence the expression  f'(x)  in terms of the secant function is sec²x

f'(x) = 1/cos²x

For the function to be defined, it means that cos²x ≠ 0

cos²x ≠ 0

cos x ≠ 0

x ≠ cos⁻¹0

x ≠ 90⁰

Hence the value of x must not be equal to 90 for the function to be defined. x can be defined at when x = 0 since cos 0 = 1, the equation will  becomes f'(0) = 1/cos²0 = 1/1 = 1.

Hence the function is defined at 0≤x<90

Nigeria's predicted population in 2020 is 208 million, rounded to the nearest million.

Relative change, also known as percent change, is a measure of the percentage increase or decrease in a quantity over time. In the context of population, relative change refers to the percentage change in the size of a population over a given period.

To calculate relative change in population, you would take the difference between the final population size and the initial population size, divide by the initial population size, and multiply by 100 to get the percentage change.

To find the relative change in Nigeria's population over the decade from 2000 to 2010, we use the formula:

Relative change = (new value - old value) / old value

Relative change in Nigeria's population from 2000 to 2010:

= (160 - 123) / 123

= 0.300813

So Nigeria's population increased by approximately 30.08% over the decade from 2000 to 2010.

To predict Nigeria's population in 2020, we apply this same relative change to the 2010 population:

Population in 2020 = Population in 2010 + (Relative change × Population in 2010)

Population in 2020 = 160 + (0.300813 × 160)

Population in 2020 = 160 + 48.13008

Population in 2020 = 208.13008 million

Rounding this to the nearest million, we get:

Population in 2020 = 208 million

Therefore, Nigeria's predicted population in 2020 is 208 million, rounded to the nearest million.

Answer:

The market equilibrium price is approximately $36.43 per barrel.

Step-by-step explanation:

To find the market equilibrium price, we need to set the quantity supplied (QS) equal to the quantity demanded (QD) and solve for the price (P).

Given:

QS = -250 + 7P

QD = 260 - 7P

Setting QS equal to QD:

-250 + 7P = 260 - 7P

Now, let's solve for P:

Add 7P to both sides:

-250 + 7P + 7P = 260 - 7P + 7P

Combine like terms:

14P - 250 = 260

Add 250 to both sides:

14P - 250 + 250 = 260 + 250

Simplify:

14P = 510

Divide both sides by 14:

14P/14 = 510/14

Simplify:

P = 36.43

The market equilibrium price can be found by setting the quantity supplied (QS) equal to the quantity demanded (QD) and solving for the price (P) that satisfies this condition.

In the given scenario, the supply function is QS = -250 + 7P, and the demand function is QD = 260 - 7P. To find the equilibrium price, we set QS equal to QD:

-250 + 7P = 260 - 7P

Simplifying the equation, we get:

14P = 510

Dividing both sides by 14, we find:

P = 36.43

Therefore, the market equilibrium price is approximately $36.43 per barrel. At this price, the quantity supplied and quantity demanded will be equal, resulting in a state of equilibrium in the perfectly competitive domestic crude oil market.

The dimensions of the fencing is 28 ft and 37 ft respectively.

He use 130 feet of fencing to go around a rectangular pool and patio.

The length of the area is 9 more than the width.

The dimension of the fence can be found as follows:

Therefore,

perimeter of the rectangular fence = 2(l + w)

where

Hence,

l = 9 + w

perimeter of the rectangular fence = 2(w + 9 + w)

perimeter of the rectangular fence = 2(2w + 9)

130 = 4w + 18

130 - 18 = 4w

112 = 4w

w = 112 / 4

w = 28 ft

l = 9 + 28 = 37 ft

Therefore, the width and length of the fencing is 28 ft and 37 ft respectively.

Step-by-step explanation:

The displacement made by the cyclist is 0, this is caused by the same path traveled by the cyclist.

Displacement is the change in position of a moving object relative to a frame of reference. That is, locking is a change in the initial position of the object to the final position of the object.

The displacement in this case is calculated by the Pythagorean theorem.

Displacement² = S₁² + S₂²

The displacement will be zero when the start and end points are the same, that's what makes the problem zero. In the question, the distance traveled by the rider is 45 km, but because there is no position lock because the rider is traveling the same path, the closing done by the cyclist is 0.

The total number of wiretaps authorized between 2000 and 2005 is approximately 11,271.

To find the total number of wiretaps authorized between 2000 and 2005, we need to evaluate the definite integral of the function w(t) = 430e^(0.065t) over the interval [10, 15]. This will give us the cumulative number of wiretaps authorized during that period.

The integral of w(t) with respect to t can be calculated as follows:

∫[10, 15] w(t) dt = ∫[10, 15] 430e^(0.065t) dt

To evaluate this integral, we can use the power rule of integration for exponential functions. According to the power rule, if we have an integral of the form ∫a^x e^(kx) dx, the result is (1/k) × e^(kx).

Applying the power rule to our integral, we get:

∫[10, 15] 430e^(0.065t) dt = (1/0.065) × e^(0.065t) ∣[10, 15]

Now, let's substitute the upper and lower limits into the expression:

= (1/0.065) × (e^(0.065 × 15) - e^(0.065 × 10))

Evaluating the exponential terms:

= (1/0.065) × (e^(0.975) - e^(0.65))

Calculating the numerical value:

≈ (1/0.065) × (2.648721 - 1.916134)

≈ (1/0.065) × 0.732587

The regular expression is ^(a(aa)*b)$.

To create a regular expression for the language L = {w = {a,b}* | w has an odd number of 'a's and ends with 'b'}, we can use the following expression:

^(b|(a(aa)*b))$

Breaking it down:

^ indicates the start of the string.

(b|(a(aa)*b)) matches either 'b' or a sequence of 'a's followed by an odd number of 'a's and 'b'.

(aa)* matches zero or more pairs of 'a's.

$ indicates the end of the string.

This regular expression ensures that the string starts with 'b' or a sequence of 'a's, followed by an odd number of 'a's, and ends with 'b'. Any additional characters or sequences in between are not allowed.
