Answer:

y=-10x+89

Step-by-step explanation:

Remember that the derivative tells us the slope of the tangent line at a given point.

So, we want to find the equation of the tangent line to f(x) at x=8.

We are given that f'(8) is -10.

In other words, the slope of the tangent line to f(x) at x=8 is -10.

We also know that f(8)=9. In other words, we have the point (8,9).

So, we can use the point-slope form to figure out the equation:

y-y_1=m(x-x_1)

Substitute -10 for m and let (8,9) be (x₁, y₁). So:

y-9=-10(x-8)

Distribute the -10:

y-9=-10x+80

Add 9 to both sides:

y=-10x+89

And we're done!

Which equation represents the standard form of the equation y= (x + 3)² - 4?
lilavasa [31]

Answer:

The answer is B. y = x^2 + 6x + 5

Step-by-step explanation:

Because y = (x + 3)^2 - 4 = x^2 + 6x + 9 - 4 = x^2 + 6x + 5

So the answer in this question is B.

How do I solve problem 7?
miskamm [114]

Answer:

16ᵗʰ Term of the sequence is 1010

Step-by-step explanation:

7.)

Here,

First Term = a₁ = 5

Common Difference = d = 67

Now, For 16ᵗʰ term, n = 16

<em>aₙ = a + (n - 1)d</em>

a₁₆ = 5 + (16 - 1) 67

a₁₆ = 5 + 15 × 67

a₁₆ = 5 + 1005

a₁₆ = 1010

Thus, 16ᵗʰ Term of the sequence is 1010

Differentiating a Logarithmic Function in Exercise, find the derivative of the function. See Examples 1, 2, 3, and 4.
kotykmax [81]

Answer:

f'(x) = -\frac{2x}{1 - x^{2}}

Step-by-step explanation:

The derivative of an addition/subtraction of terms is the addition/subtraction of the derivatives of these terms.

The derivative of a constant is 0.

The derivative of a*x^{n} is a*n*x^{n-1}. The derivative of x^{3} is 3x^{2}, for example.

The derivative of the ln function:

If we have:

y = \ln{g(x)}

The derivative is

y' = g'(x)*\frac{1}{g(x)}

In this problem, we have that:

y = \ln{1 - x^{2}}

So g(x) = 1 - x^{2} and g'(x) = -2x

So the derivative to this function is

f'(x) = -\frac{2x}{1 - x^{2}}
