Answer:

LCM is 120. GCF is 8.

Step-by-step explanation:

LCM of 24: 3 and 8,

2, 4

2, 2

You need to prime factorize first so 24: 2 x 2 x 2 x 3

LCM of 40: 4 and 10

2, 2 2, 5

So 2 x 2 x 2 x 5

Greater number of each of them: 2 x 2 x 2 x 3 x 5= 120

GCF of 24:

Factors of 24: 1, 2, 3, 4, 6, 8, 12

Factors of 80: 1, 2, 4, 5, 8, 10, 20

So the GCF is 8

$f$ is differentiable across its domain, so the MVT says there is some value of $c$ in the open interval $(a,b)$ such that

$f'(c)=\dfrac{f(b)-f(a)}{b-a}$

You have

$f(x)=Ax^2+Bx+C\implies f'(x)=2Ax+B$

so the equation above becomes

$2Ac+B=\dfrac{(Ab^2+Bb+C)-(Aa^2+Ba+C)}{b-a}$

Solve for $c$ .

$2Ac+B=\dfrac{A(b^2-a^2)+B(b-a)}{b-a}$
$2Ac+B=A(b+a)+B$
$2Ac=A(b+a)$
$c=\dfrac{b+a}2$

so $c$ is indeed the average of the endpoints, i.e. the midpoint.

What is the equation of the line parallel to 3x + 5y = 11 that passes through the point (15, 4)?

soldier1979 [14.2K]

Answer:

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is 3x + 5y = 11

We must first write the equation in the general equation above

So we have

5y = - 3x + 11

Divide both sides by 5

Comparing with the general equation above

Slope = - 3/5

Since the lines are parallel their slope are also the same

Slope of parallel line = - 3/5

So the equation of the line using point

(15, 4) and slope - 3/5 is

We have the final answer as

Hope this helps you

Let f(x)=(x-2)^3+8 Find the inverse of f(x). Please show steps in written form would be gladly appreciated

Tatiana [17]

Hello from MrBillDoesMath!

Answer:

(x-8)^(1/3) +2

Discussion:

To find the inverse of a function swap the values of x and y in the original equation y = (x-2)^3 +8 and solve for y.

y = (x-2)^3 +8 => original function. swap x and y values

x = (y-2)^3 + 8 => subtract 8 from both sides

x - 8 = (y -2)^3 => take cube root of both sides

(x-8)^(1/3) = y - 2 => add 2 to both sides

(x-8)^(1/3) +2 = y => y is the inverse

Thank you,

MrB
