Answer:

Step-by-step explanation:

The fraction of the profit that belongs to Sheldon is ...

  Sheldon / Leonard = 2 / 5

  Sheldon / Total = 2 / (2 + 5) = 2/7

Then Sheldon's portion of the $28 profit is ...

  Sheldon's profit = 2/7 × $28 = $8

Sheldon makes $8 profit on the first item they sell.

The x-intercept are x = 0, x = -1.9, x = 0.35, and x = 1.5.

The local minimum is 1.

The function is increasing at the interval (-1.5, 0.5) and (1, ∞).

The function is decreasing at the interval (∞, -1) and (0, 1.5).

A function is a relationship between inputs where each input is related to exactly one 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,

h(x) = [tex]x^4[/tex] - 3x² + x

The x-intercept is when h(x) = 0.

0 = [tex]x^4[/tex] - 3x² + x

From the graph, we see that,

The x-intercept are at x = 0, x = -1.9, x = 0.35, and x = 1.5

Now,

h(x) = [tex]x^4[/tex] - 3x² + x

h'(x) = 4x³ - 6x

h''(x) = 12x² - 6 (positive)

So,

h(x) has a minimum value.  

h'(x) = 0

4x³ - 6x = 0

4x³ = 6x

4x² = 6

x² = 6/4

x² = 3/2

x² = 1.5

x = ±√1.5

x = ±1.22

The minimum values are:

h(1.22) =  [tex]x^4[/tex] - 3x² + x = -1

h(-1.22) =  [tex]x^4[/tex] - 3x² + x = 1

The local minimum is 1.

From the graph, we see that,

The function is increasing at the interval (-1.5, 0.5) and (1, ∞).

The function is decreasing at the interval (∞, -1) and (0, 1.5).

Thus,

The x-intercept are x = 0, x = -1.9, x = 0.35, and x = 1.5.

The local minimum is 1.

Increasing intervals are (-1.5, 0.5) and (1, ∞).

Decreasing intervals are (∞, -1) and (0, 1.5).

Answer:

The ratio of y to x is the slope

The equation of the graph is y = 1/2x

Step-by-step explanation:

In this scenario, we see that 1/2 of x always equals y, so the y-intercept is 0. This means that the slope is equal to 1/2, and that is the ratio of y to x.

Answer:

7.07

Step-by-step explanation:

Angle M is 63 degrees because all 3 angles must add to 180.  

Now use the law of sines:  

sin(90)/x = sin(63)/6.3  

Cross multiply: 6.3 sin (90) = x sin (63)  

Divide by sides by sin (63): (6.3 sin (90))/sin (63) = x  

Use a calculator: 7.07

Step-by-step explanation:

the description is very difficult to understand with special characters and potential typing errors.

I suspect the definition is

function(x) = 32 - x²

function(-5)function(-5) is then very easily calculated.

we need to calculate function(-5) and then square the result, as function(-5)function(-5) is just a simple multiplication of the function results.

function(-5) = 32 - (-5)² = 32 - 25 = 7

so,

function(-5)function(-5) = 7 × 7 = 49

Answer:

The answer to this is 10 visits.

Step-by-step explanation: For this algebra, take a guess at first, and then you should be able to find an answer from there. All you have to do mathematically, is calculate (using the two starting values), when the prices are the same. For this, the equation would look something like: 5x + 130 and 3x + 150. X represents the unknown number of visits. When x is = 10, the prices are the same, 180 = 180. Edit: Another way you can do this, is graph a line of the two equations, and see what point they intercept. The X value of the point usually is the number of times something occurs until the price is the same, whereas the y value of the point is usually the price.

The slope of the line that is perpendicular to line AB is: 1/2.

Recall:

Given:

A(-1,10)

B(5,-2)

Slope of AB:

[tex]m = \frac{-2 - 10}{5 -(-1)} = \frac{-12}{6} \\\\\mathbf{m = -2}[/tex]

The slope of the line that is perpendicular to line AB will be the negative reciprocal of the slope of AB.

Therefore, the slope of the line perpendicular to AB is: 1/2.

Answer:

Yes!

Step-by-step explanation:

Here, ratios can be rewritten by fractions.

12:6 is [tex]\frac{12}{6}[/tex] which equals to 2,

2:1 is also [tex]\frac{2}{1}[/tex] which is 2.

To get 12 from 2, you multiply by 6.

Multiply the same thing to the denominator(1), and you get 6. So:

12:6 = 2:1
