find an equation of the tangent line to the curve at the given point. y = 3ex cos(x), (0, 3)

Answers

Answer 1

A equation of the tangent line to the curve is y = 3x + 3

The term tangent line in math is calculated as an equation of the tangent line we have to find the derivative of the function and its value at the given point.

And then we have to the function given is a product of an exponential and cosine function. We will have to use product rule.

Finally, we have to write the equation of tangent line by point slope form.

Here we have the curve equation as,

=> y = 3eˣcos(x)

Now, we have to calculate the derivative y' from the given equation, then we get,

=> y' = = 3(eˣ (−sin x) + (cos x) eˣ)

Now, it can be simplified as,

=>y' = 3eˣ(cos x − sin x)

Here we have given that the the slope of the tangent line at (0, 3), then the value of

=> 3e⁰(cos0−sin0) = 3(1−0) = 3

Then the equation is written as

=> y − 3 = 3(x − 0)

=> y = 3x + 3

The 34th term of the arithmetic value progression is a₃₄ = 229

What is Arithmetic Progression?

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the sequence be represented as A

Now , the value of A is

A = {-2,5,12,19...}

And , to find the 34th term of the sequence {-2, 5, 12, 19, ...}, we first need to find the common difference between consecutive terms:

The common difference = 5 - (-2) = 7

So, to get the 34th term, we can use the formula for the nth term of an arithmetic sequence:

an = a1 + (n-1)d

where a1 is the first term, d is the common difference, and n is the term number we want to find.

Plugging in the values we have:

a₃₄ = -2 + (34-1)7

a₃₄ = -2 + 231

a₃₄ = 229

Hence , the 34th term of the sequence is 229

Find the Are of the Shaded Region

Answers

Area of 3/4 circle = 3/4 x π x r²
= 3/4 x 22/7 x 6²
= 84.86cm²

That should be the correct answer
Hope this helps!!

Answer:

≈ 84.8 cm²

Step-by-step explanation:

The area of the shaded region is calculated as

area of circle - area of unshaded sector

area of circle = πr² = π × 6² = 36π

unshaded area = area of circle × fraction of circle

                          = 36π × [tex]\frac{90}{360}[/tex] = 36π × [tex]\frac{1}{4}[/tex] = 9π

area of shaded region = 36π - 9π = 27π ≈ 84.8 cm² ( nearest tenth )

Step-by-step explanation:

John wants to earn 25% of his investment of $50,000 which is:

= 25% * 50,000

= $12,500

He has expenses of $9,600 yearly so the rent he should charge per year in order to make his 25% requirement as income is:

= Expenses + Return

= 9,600 + 12,500

= $22,100

Rent per month is:

And the East Anglians ran off at once . . . The Danes held the battlefield. Then they got horses and afterwards took control of East Anglia, and plundered and burned the countryside for four months - they even went as far as the wild fens and killed men and beasts and set fires throughout the fens, and burned down Thetford and Cambridge and then turned south to the Thames . . . Then they turned back to their ships with their plunder. As they were going to their ships, the English army should have come back into the field to prevent them turning inland again. And that's when the English army went home . . . [A]ll the council was summoned to the king to determine how to defend the realm. But whatever was decided on did not last even a month.
