4x+5(g(x)):: 8x+13

g(x):: 8x+13/4x+5

Answer:

g(x) = 2x + 2

Step-by-step explanation:

One is given the following information:

One is asked to find the following:

Remember, (f o g (x)) is another way of representing a composite function. A more visual way of representing this composite function is the following (f(g(x)). In essence, one substitutes the function (g(x)) into the function (f(x)) in places of the varaible (x). Thus, represent this in the form of an equation:

f(g(x)) = 8x + 13

Substitute the given infromation into the equation:

4(g(x)) + 5 = 8x + 13

Solve for (g(x)) in terms of (x). Remember to treat (g(x)) as a single parameter:

4(g(x)) + 5 = 8x + 13

Inverse operations,

4(g(x)) + 5 = 8x + 13

4(g(x)) = 8x + 8

g(x) = (8x + 8) ÷ 4

g(x) = 2x + 2

Translate the given point and line together so that you get a new point and a new line that passes through the origin. This turns the problem into finding the distance between the new point,

p = (4, 4, -4) - (-1, 1, 3) = (5, 3, -7)

and the new line,

r*(t) = r(t) - ⟨-1, 1, 3⟩ = ⟨2t, 2t, -3t⟩

Let p = ⟨5, 3, -7⟩, the vector starting at the origin and pointing to p. Then the quantity ||p - r*(t)|| is the distance from the point p to the line r*(t).

Let u be such that ||p - r*(t)|| is minimized. At the value t = u, the vector p - r*(t) is orthogonal to the line r*(t), so that

(p - r*(u) ) • r*(u) = 0

I've attached a sketch with all these elements in case this description is confusing. (The red dashed line is meant to be perpendicular to r*(t).)

Solve this equation for u :

p • r*(u) - r*(u) • r*(u) = 0

p • r*(u) = r*(u) • r*(u)

and x • x = ||x||² for any vector x, so

p • r*(u) = ||r*(u)||²

⟨5, 3, -7⟩ • ⟨2u, 2u, -3u⟩ = (2u)² + (2u)² + (-3u)²

10u + 6u + 21u = 4u ² + 4u ² + 9u ²

17u ² - 37u = 0

u (17u - 37) = 0

==>   u = 0   or   u = 37/17

We ignore u = 0, since the dot product of any vector with the zero vector is 0.

Then the minimum distance distance between the given point and line is

||p - r*(u)|| = ||⟨5, 3, -7⟩ - 37/17 ⟨2, 2, -3⟩|| = √(42/17)

Answer:

Maximum: 1

Minimum: -1

Step-by-step explanation:

To solve this, we can find the derivative of the function and then solve for when the derivative is equal to 0, finding the local maximum and minimum values in this function. Then, we can compare those points to the endpoints of the interval to find the maximum and minimum.

Using the Quotient Rule, we can say that

(f/g) ' = (f'g - fg')/(g²)

[tex]\frac{2x}{x^2+1}dx = \frac{\frac{d}{dx}(2x) * (x^2+1) - \frac{d}{dx} (x^2+1) * (2x) }{(x^2+1)^2} \\= \frac{2 *(x^2+1) - (2x)*(2x)}{(x^2+1)^2} \\[/tex]

Since we just need to solve for 0, we can disregard for the bottom part, resulting in

2(x²+1)-(2x)(2x) = 0

2x²+2-4x² = 0

2-2x² = 0

add 2x² to both sides to isolate the x² and its coefficient

2x² = 2

divide both sides by 2

x²=1

x = ±1

Therefore, we have 4 possible values for the maximum and minimum over this interval:

-2, -1, 0, 1

Trying each of these numbers into f(x),

f(-2) = -4/5

f(-1) = -2/2 = -1

f(0) = 0/1 = 0

f(1) = 2/2 = 1

Therefore, the maximum and minimum values of the function over the given interval are 1 and -1 respectively

The skirt = s

The sweater is twice as much so 2s

The total sum has to equal or be less than $75

Inequality = s + 2s <=75

Simplify to 3s <= 75

Most the skirt can cost: solve for s:

3s <= 75

Divide both sides by 3

S <= 25

The most the skirt can cost is $25

Answer:

Inequality: s ≤ 25

Max skirt cost: $25

Step-by-step explanation:

s = skirt cost

x =  sweater cost

Since the sweater costs twice as much as the skirt, an equation will look like this:  

x = 2s

Since her budget is $75, that means she can spend $75 or less but not more, so another equation will look like this:

x + s ≤ 75

Plug 2s into the bottom equation

2s + s ≤ 75

Add up the terms

3s ≤ 75

Divide both sides by 3, the coefficient, to isolate s, the variable.

3s/3 ≤ 75/3

s ≤ 25

That means she can spend $25 or less on a skirt.

Step-by-step explanation:

3/40 is the correct answer

The percent profit that Rabi made will be 10.5%

Let's assume that the price of the house is $100.

Since he fixed the marked price of the good to make a profit of 30%, then the price will be:

= $100 + (30% × $100)

= $100 + $30

= $130

Now, there is a discount of 15%, then the selling price of the good will be:

= $130 - (15% × $130)

= $130 - (0.15 × $130)

= $130 - $19.50

= $110.50

Then, the percentage of profit made will be:

= [($110.50 - $100) / $100] × 100%

= $10.50/$100 × 100%

= 10.5%

In conclusion, the percent profit that he makes is 10.5%.

The measure of each of the remaining angles in the right angle triangle is 45 degrees.

To find the measure of the remaining angles in the triangle, we can use the fact that the sum of the angles in any triangle is always 180 degrees. Since we know one angle is 90 degrees, we can find the measure of the other two angles by subtracting 90 from 180.

Let's call the remaining two angles A and B. Thus, we have:

Angle A + Angle B + 90 degrees = 180 degrees.

Rearranging the equation, we get:

Angle A + Angle B = 90 degrees.

Since the two sides of the triangle adjacent to the right angle are equal (given as 9 and 9), we can conclude that the remaining two angles are congruent (equal). Let's call the measure of each of these angles x.

Therefore, we have:

x + x = 90 degrees.

Simplifying, we get:

2x = 90 degrees.

Dividing both sides by 2, we find:

x = 45 degrees.

Answer:

$540.98

Step-by-step explanation:

future value= $ 50,000

number of deposits (n)= 8*12 = 96

rate (r) = 4% per month

= 4÷12 per annum

= 0.33% p.a

i = 0.33÷100

= 0.0033

We know,

Future value of annuity = P÷i [ (1 + i)^n - 1 ]

$50,000 = P÷ 0.0033 [ ( 1+0.0033)^96 - 1]

$50,000 * 0.0033=P [ (1.0033)^96 - 1 ]

$165 = P*0.305

P = $165÷0.305

P = $ 540.98

Rough::

let x= 1.0033)^96

log x = 96 * log (1.0033)

log x = 0.1156

x = Antilog (0.1156)

= 1.305

1.305 - 1 = 0.305
