integral of e^(5x)*cos(6x)

The angle where the tangent intersect is as follows:

m∠L = 55 degrees.

A line that touches the circle at a single point is known as a tangent to a circle.

Therefore, the measure of the angle formed by the intersection of tangents is equals to half the difference of the intercepted arcs.

Hence,

m∠L = 1 / 2 (235 - (360 - 235))

m∠L = 1 / 2 (235 - 125)

m∠L = 1 / 2 × 110

m∠L =  55 degrees

Therefore, the measure of the angle formed by the intersection of the tangent is 55 degrees.

The slope or gradient of a line is a number that describes both the direction and the steepness of the line.

Given that, the rate of change at which the water level rise is 15/4 cm/minute.

Hence, the slope of the line is 13/6.

Taking x to represent the time in minutes and y to represent the rise in cm then,

Therefore,

4 minutes = 15 cm

So, in 1 minute, the rise is 15/4 cm

Thus, in 8 minutes, the rise will be ;

After 2.94 Hr. or approximately 3 Hr. both cars will be 250 miles apart.

We have,

The value of the speed of the car moving in the north direction =35 mph

The value of the speed of the car moving in the south direction=50 mph

From above, we can conclude that both are going in the opposite direction

So, the value of the net speed/ relative speed of both the car will be =35+50=85 mph

As we know,

The value of distance can be determined by using the relationship:

Distance = speed * time

So, for determining the value of time, we will put the value of total distance covered and the value of relative speed in the above expression.

The trigonometric ratios for sine and tangent, where arctan(√3/3) is β, indicates that we get;

α = 60°, β = 30°, h = √3, k = 3, and r = 2·√3

Trigonometric ratios expresses the relationship between an interior angle and two of the sides of a right triangle.

The details of the question are;

arctan(√3/3) = Angle β

The trigonometric ratio for tangent indicates that we get;

tan(β) = h/k

Therefore, arctan(h/k) = β

However, arctan(√3/3) = β

The comparison of the above two equations indicates that we get;

h/k = √3/3

Therefore, if h = √3, k = 3

tan(α) = k/h

Therefore, tan(α) = 3/√3 = √3

r = √(h² + k²)

r = √(3 + 9) = √(12) = 2·√3

sin(β) = h/r

Therefore, sin(β) = √3/(2·√3) = 1/2

β = arcsin(1/2) = 30°

The specified triangle is a right triangle, therefore;

α + β = 90°

α = 90° - β

α = 90° - 30° = 60°

The coefficient of x² in the Taylor series for sin²x about x=0 is 1

If a Taylor Series is centred at 0, then the series is known as the Maclaurin series.

Maclaurin series is given by f(x) = [tex]\text{\Large$ \Sigma$}\limits^{\infty}_{k=0} \frac{f^{(k)}(a)}{k!}x^k[/tex]

f(x) = sin²x

We need coefficient of x², let us take n=5

f(x) = [tex]\text{\Large$ \Sigma$}\limits^{\infty}_{k=0} \frac{f^{(k)}(a)}{k!}x^k[/tex]

f^0(x) = sin²x => f^0(0) = 0

f^1(x) = 2 sinx cosx => f^1(0) = 0

f^2(x) = -2 sin²x + 2 cos²x => f^2(0) = 2

f^3(x) = -8 sinx cosx => f^3(0) = 0

f^4(x) = 8 sin²x - 8 cos²x => f^4(0) = -8

f^5(x) = 32 sinx cosx => f^5(0) = 0

f(x) = 0(x^0) + 0(x^1) + (2/2!)(x^2) + (0/3!)(x^3) + (-8/4!)(x^4) + (0/5!)(x^5)

The probability that neither of the 3 bits is recovered successfully is 8/729.

Each bit is transmitted over the channel with a success probability of 1/3 and a failure probability of 2/3. The success and failure of each bit are independent, meaning that the success of one bit does not affect the success of another bit.

The probability of successfully recovering all 3 bits is (1/3) * (1/3) * (1/3) = 1/27.

Similarly, the probability of failing to recover all 3 bits is (2/3) * (2/3) * (2/3) = (8/9)^3 = 8/729.

In this case, the integrand is evaluated at the bounds of the integral, both integrals.

We can make the substitution u = cos(t) and du = -sin(t) dt.

The integral becomes: ∫0 ecos(t)sin(2t) dt = -∫0 eu * sin(2arcsin(u)) du

Now we can use integration by parts, letting dv = eu and u = sin(2arcsin(u)), so v = -e * arcsin(u).

The integral becomes: ∫0 ecos(t)sin(2t) dt = [-e * arcsin(u) * sin(2arcsin(u))]0 - ∫0 e * arcsin(u) * cos(2arcsin(u)) du

Using the identity sin(2θ) = 2sin(θ)cos(θ), we can simplify the first term to:

∫0 ecos(t)sin(2t) dt = [2e * arcsin(u) * sin(arcsin(u))cos(arcsin(u))]0 - ∫0 e * arcsin(u) * cos(2arcsin(u)) du

Since u = cos(t), we can write the first term as: ∫0 ecos(t)sin(2t) dt = [2e * arcsin(cos(t)) * sin(t)cos(t)]0 - ∫0 e * arcsin(cos(t)) * cos(2arcsin(cos(t))) du

The first term is equal to 0 since it is evaluated at the bounds of the integral. The second term can be simplified using the identity cos(2θ) = cos^2(θ) - sin²(θ), so: ∫0 ecos(t)sin(2t) dt = -∫0 e * arcsin(cos(t)) * (cos^2(arcsin(cos(t))) - sin^2(arcsin(cos(t)))) du

Using the trigonometric identities sin^2(θ) + cos²(θ) = 1 and cos²(θ) = 1 - sin²(θ), we can simplify the integrand to: ∫0 ecos(t)sin(2t) dt = -∫0 e * arcsin(cos(t)) * (1 - 2sin²(arcsin(cos(t)))) du

Since the integrand is separable, we can rewrite it as: ∫0 ecos(t)sin(2t) dt = -∫0 e * arcsin(cos(t))du - 2∫0 e * sin²(arcsin(cos(t))) du

The first integral is straightforward to evaluate, giving us:

∫0 ecos(t)sin(2t) dt = -e * arcsin(cos(t)) |0

The second integral is a bit more complicated, but we can use the identity sin²(θ) = (1 - cos(2θ)) / 2, so:

∫0 ecos(t)sin(2t) dt = -e * arcsin(cos(t)) |0 - e * (1 - cos(2arcsin(cos(t)))) / 2 |0

Thus, the integrand is evaluated at the bounds of the integral, both integrals.

The market equilibrium point for the following demand and supply functions are, demand and supply p = 224.2

He estimated the market demand and supply function as follows demand : P = −2q + 280     (Equation-1)

supply: P =  8q + 1          (Equation-2)

We need to find the equilibrium price

The equilibrium price (EP) is the price where the demand for a product or service balances its supply. .

At equilibrium price

Demand function = supply function

−2q + 280 = 8q + 1

280 - 1 = 8q + 2q

279 = 10q

q = 279/10

q = 27.9

We can substitute equation-1,

The equilibrium price = −2q + 280

The equilibrium price = -2(27.9) + 280

The equilibrium price = -55.8 + 280

The equilibrium price = 224.2

We can substitute equation-2,

The equilibrium price = 8q + 1

The equilibrium price = 8(27.9) + 1

The equilibrium price = 223.2 + 1

The equilibrium price = 224.2

demand: p = 224.2

supply: p = 224.2

The best mathematical operation to use when considering the probability of data loss from single drive failure is XOR.

Data storage is a critical process, as any data loss could have disastrous consequences.

The XOR technique uses one extra device (C) to store the exclusive OR result of the data stored on devices A and B. This means that for each bit k, the value of Ck is the exclusive OR of ak and bk.

This means that if bit k fails on device A or B (not both), it can be reconstructed from bit k on device C. This is because the exclusive OR of two identical bits is 0 and the exclusive OR of two different bits is 1, which can be used to reconstruct the failed bit from the other one.

The same cannot be said of the AND or OR technique. If we use the AND technique, the value of Ck would be the logical AND of ak and bk.

In this case, the failed bit could not be reconstructed from the other bit, as the logical AND of two identical bits is the same bit and the logical AND of two different bits is 0.

The same problem applies for the OR technique, as the value of Ck would be the logical OR of ak and bk, and the failed bit could not be reconstructed from the other bit.
