The equation of the tangent line to the curve \(y = \frac {(x^2 - 1)}{ (x^2 + x + 1)}\) at the point (1, 0) is y = (2/3)x - 2/3.

To find the equation of the tangent line to the curve at the point (1, 0), we need to find the slope of the tangent line and then use the point-slope form of a linear equation.
Let's differentiate \(y = \frac {(x^2 - 1)}{ (x^2 + x + 1)}\) using the quotient rule:

\(y' = [(2x)(x^2 + x + 1) - (x^2 - 1)(2x + 1)] / (x^2 + x + 1)^2\)
Substituting x = 1 into the derivative expression:

\(y'(1) = [(2(1))(1^2 + 1 + 1) - (1^2 - 1)(2(1) + 1)] / (1^2 + 1 + 1)^2\)

        \(= [2(3) - (0)(3)] / (3)^2\)

        = 6/9

        = 2/3

Using the point-slope form y - y₁ = m(x - x₁), where (x₁, y₁) = (1, 0) and m = 2/3 we get,  
y - 0 = (2/3)(x - 1)

y = (2/3)x - 2/3

The point-slope form of a linear equation is given by y - y₁ = m(x - x₁) where (x₁, y₁) is a point on the line, and m is the slope of the line.

Therefore, the equation of the tangent line to the curve y = (x^2 - 1) / (x^2 + x + 1) at the point (1, 0) is y = (2/3)x - 2/3.

Hello there!

When we are given the graph of a line and two points on the graph, we can calculate the slope of the line using Rise/Run.

Rise=How many units we move up (here, the rise is 3)

Run=How many units we move left or right (Here, the run is 5)

So the slope of this line is \(\frac{3}{5}\)

Hope this helps you!

Answer:

1) c = 25m + 90

2) c = 17m; $85

3) c = 10m + 15; $135

Step-by-step explanation:

Let m = number of months

1)

c = 25m + 90

2)

c = 17m

For 5 months, m = 5.

c = 17m = 17 × 5 = 85

$85

3)

c = 10m + 15

1 year = 12 months, so m = 12

c = 10m + 15 = 10 × 12 + 15 = 120 + 15 = 135

$135

Answer:

  2/15

Step-by-step explanation:

The given expression for θ can be rewritten to ...

  5sin(θ + arctan(-3/4)) = 0

This will have solutions ...

  θ +arctan(-3/4) = nπ

  θ = nπ - arctan(-3/4) = nπ + arctan(3/4)

__

The corresponding values of sine and cosine will be ...

  sin(arctan(3/4)) = 3/5

  cos(arctan(3/4) = 4/5

or both values may be negative. Either sign will give the same result in the expression we're to find.

  (2sin(θ) -cos(θ))/(sin(θ) +3cos(θ)) = (2(3/5) -(4/5))/(3/5 +3(4/5))

  = ((6 -4)/5)/((3+12)/5) = 2/15

  \(\boxed{\dfrac{2\sin\theta-\cos\theta}{\sin\theta+3\cos\theta}=\dfrac{2}{15}}\)

Step-by-step explanation:

It is 76 degrees F at the 6000-foot level of a mountain, and 49 degrees

F at the 12000-foot level of a mountain.

Write a linear equation to find the temperature T at an elevation e on the

mountain, where e is in thousands of feet.:

:

Find the slope using the slope formula: m = %28y2-y1%29%2F%28x2-x1%29

Assign the given values as follows

x1 = 6 (for 6000 ft); y1 = 76

x2 = 12(for 12000ft); y2 = 49

:

m = %2849-76%29%2F%2812-6%29 = %28-27%29%2F6 = -9%2F2

;

Use the point slope equation y - y1 = m(x - x1) so create the equation

y - 76 = -9%2F2(x - 6)

y - 76 = -9%2F2x - (-27)

y - 76 = -9%2F2x + 27 + 76

y = -9%2F2x + 103; is the equation

Using e and T

T = -9%2F2e + 103

As the x-values go to negative infinity, the function's values go to positive infinity​

Step-by-step explanation:

O As the x-values go to positive infinity, the function's values go to negative infinity.   FALSE - it goes to positive infinity as we go to the right

O As the x-values go to zero, the function's values go to positive infinity   FALSE- at zero the value is zero

O. As the x-values go to negative infinity, the function's values are equal to zero. FALSE - it goes to positive infinity as we go to the left

O As the x-values go to negative infinity, the function's values go to positive infinity​ TRUE - it goes to positive infinity as we go to the left

As the x-values go to negative infinity, the function's values go to positive infinity​.

Option D is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The end behavior of a function refers to what happens to the values of the function as the input variable becomes very large.

Now,

From the graph,

We see that,

As the x-values go to positive infinity, the function's values go to positive infinity​

As the x-values go to negative infinity, the function's values go to positive infinity​.

Thus,​

As the x-values go to negative infinity, the function's values go to positive infinity​.

Answer:

125 + (x × 75) = y

Step-by-step explanation:

If y represents the total cost, ant x represents the number of hours he works, we can use this equation:

x × 75 = y

But now we also need to add the fee of $125.

125 + (x × 75) = y

Therefore, your answer is 125 + (x × 75) = y.

For 5 months site b be less expensive than site a.

From the given question we get to know that on-site $50 is a must and %5 will be paid per month, and on-site b $15 will be per to promote his brand and there is no start-up fee.

Let's take the n to be x.

We have to find how many months will b site be less expensive than site a.

So total expenses for site a = 50 + 5x

and total expenses for site b = 15x

We get an equation

50+5x =15x

10x=50

x=5

Therefore for 5 months site b will be less expensive than site a.

The sample mean variance of the continuous distribution will be 0.3428.

The population variance is equal to the sample size divided by the variance of the sampling distribution of the mean.

14 is the greatest and 1 is the smallest value in a uniform continuous distribution.

36-size samples are taken from the distribution.

Now,

Variance among the population = 14 – 2 = 12

The sample size is 36.

Given that the sample means' variance is defined as;

= Variation in the population / Sample Size

If you replace all the values, you get;

= 12 / 35

= 0.3428

As a result, the sample mean variance will be 0.3428.

y = 8.7

Step-by-step explanation:

Assuming we can use decimal places, y is equal to 8.7.

In programming, += is often used as a substitute for y = y + x (example)

Therefore, y = y + 3.7, and since y = 5, y = 5 + 3.7, y = 8.7
