Answer:

nx^(n-1).

Step-by-step explanation:

d/dx (x^n)

We multiply by n than subtract 1 from the exponent (n):

= n x^(n-1)

Numerical examples:

d(x^3) dx = 3 * x^(3-1)

= 3x^2.

d(2x^5)/dx = 5*2 x^(5-1)

= 10x^4.

How to solve this inequality -8×+18>-22

Ksju [112]

Answer:

x < 5

Step-by-step explanation:

Step 1: Solve for x

-8x + 18 > -22

-8x + 18 - 18 > -22 - 18

-8x / -8 > -40 / -8

When dividing by negative, it flips the sign

Use linear approximation to estimate f (2.85 )given that f (3 )equals 2 and f prime (3 )equals 5.

Allisa [31]

Answer:

Step-by-step explanation:

Given that,

f(3) = 2

f'(3) = 5.

We want to estimate f(2.85)

The linear approximation of "f" at "a" is one way of writing the equation of the tangent line at "a".

At x = a, y = f(a) and the slope of the tangent line is f'(a).

So, in point slope form, the tangent line has equation

y − f(a) = f'(a)(x − a)

The linearization solves for y by adding f(a) to both sides

f(x) = f(a) + f'(a)(x − a).

Given that,

f(3) = 2,

f'(3) = 5

a = 3, we want to find f(2.85)

x = 2.85

Therefore,

f(x) = f(a) + f'(a)(x − a)

f(2.85) = 2 + 5(2.85 - 3)

f(2.85) = 2 + 5×-0.15

f(2.85) = 2 - 0.75

f(2.85) = 1.25

11. Maria's age is 3 years more than twice George's age. Which expression represents George's age in terms of Maria's?

leonid [27]

Answer:

Step-by-step explanation:

Okay, the catch of this question is that they do a very good job of explaining Maria's age in terms of George's age, but they leave George's age in terms of Maria's all up to you.

First start off by doing an expression of what they explicitly give you. Maria's age in terms of George's age.

Let's use variables g, representing George's age and m representing Maria's age

m = 2g + 3

Okay, this is all dandy and all, but they ask us for George's age in terms of Maria's, so we need to isolate for g.

subtract the 3 from both sides, like so:

m - 3 = 2g

then divide 2 from both sides: (remember we're dividing the whole thing)

(m-3)/2 = g

Now we have an expression for George's age in terms of Maria's.

g = (m-3)/2 or $g = \frac{m-3}{2}$

The answer that gives us this, is C.
