The relative maxima and relative minima of the function

f(x) = x^5 - 4x^3 + 3x^2 - 8x - 6

The relative minima and maxima is calculated

The procedure is done as follows

x^5 - 4x^3 + 3x^2 - 8x - 6

differentiating gives

5x^4 - 12x^2 + 6x - 8

solving the equation for the critical values are

x₁ = 0.176 + 0.73i

x₂ = 0.176 - 0.73i

x₃ = 1.518

x₄ = -1.871

The second derivative

5x^4 - 12x^2 + 6x - 8

differentiating gives

20x^3 - 24x + 6

substituting x = 1.58

20 * 1.58^3 - 24 * 1.58 + 6

= 46.966 (positive hence minima)

substituting x = -1.871

20 * -1.871^3 - 24 * -1.871 + 6

= -169.9 (negative hence maxima)

The ratio of gallons of blue paint to gallons of yellow paint will NOT make the same shade of green paint 4:9.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

A housepainter mixed 5 gal of blue paint with every 9 gal of yellow paint.

So, the ratio of gallons of blue paint to gallons of yellow paint is

Using population growth modeling it is concluded that the population of insects after 1 hour will be about 1.05 times.

The method used to calculate the growth and decay of insects or bacteria are called growth and decay modeling.

Let us assume n₀ is the initial population, then the total population n(t) after t time is given by the formula:

n(t) = n₀ [tex]e^{rt}[/tex], where r = the relative rate of growth.

Suppose an initial number of insects is x and after 15 hours it becomes 2x.

2x = x[tex]e^{15r}[/tex]

[tex]e^{15r}[/tex] = 2

Take the log of both sides of the equation

ln [tex]e^{15r}[/tex]= ln 2

15r = ln 2

r = 0.693147/15

Now, population after 1-hour = x [tex]e^{r}[/tex]

= 1.047

≈ 1.05

Hence the population of insects after 1 hour will be about 1.05 times.

Option B, x = -5 is correct answer, x = -5 is the counter example to the student's conjecture.

What is inequality?

A mathematical phrase in which the sides are not equal is referred to as being inequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

Given inequality in the question is:

x +5 < x²

We will check each option given I question by putting value of x,

putting x = -1/5

x + 5 < x²

-1/5 + 5 < (-1/5)²

24/5 < 1/25

4.8 < 0.04

This is wrong inequality , Therefore, x is not equal to -1/5

putting x = -5

x + 5 < x²

-5 + 5 < (-5)²

0 < 25

By using algebra properties, the quadratic equation y = x² - 4 contains the roots x = - 2 and x = 2.

In this problem we need to derive the quadratic equation that contains two roots: r₁ = - 2, r₂ = 2. We need to replace all roots in the factor form of the quadratic equation and expand it by algebra properties. First, replace the roots of the factor form of the quadratic equation:

y = (x - r₁) · (x - r₂)

y = (x + 2) · (x - 2)

Second, expand the expression derived in the previous step by algebra properties:

y = (x + 2) · x - (x + 2) · 2

y = x² + 2 · x - 2 · x - 4

y = x² - 4

Third, write the resulting expression:

y = x² - 4

m∠C > m∠A > m∠B is correct regarding the angles of the triangle ABC.

What is the angle of the triangle?

While the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it, the interior angles of a triangle always add up to 180°.

Here, we have

In Δ ABC, the side lengths of triangle ABC are written in terms of the variable p, where p ≥ 3.

AB=4p-1 , AC=p+4 , BC=3p

where p+4 < 3p        [as p≥3]

3p < 4p-1          [as p≥3]

⇒  4p-1> 3p > p+4

⇒AB > BC > AC

Angle opposite to AB, BC, and AC is m∠C,m∠A, and m∠B.

Answer:

Answer:

A right-angled triangle

Answer:

- 0.5 ≤ x ≤ 3.5

Step-by-step explanation:

since both ends of the interval are closed circles. This indicates that x can equal both - 0.5 and 3.5 and the values between , then

- 0.5 ≤ x ≤ 3.5

The inequality shown on the number line is -0.5 ≤ x ≤ 3.5.

Given is a number line where a value starts from -0.5 and end at 3.5, we need to write down the inequality shown on the number line,

To write down the inequality shown on the number line starting from -0.5 and ending at 3.5, we need to determine the range of values represented by the line segment.

The left endpoint of the line segment is -0.5, which means the value represented by that point is greater than or equal to -0.5.

We can express this as:

x ≥ -0.5

The right endpoint of the line segment is 3.5, which means the value represented by that point is less than or equal to 3.5.

We can express this as:

x ≤ 3.5

Combining these two inequalities, we have:

-0.5 ≤ x ≤ 3.5

This inequality represents all the values on the number line between -0.5 and 3.5, inclusive.

Hence the required inequality is -0.5 ≤ x ≤ 3.5.

The change in the amount of seed in the feeder after 7 days is 78.75 ounces.

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one.

For example, if you ran 80 meters in 10 seconds, you ran on average 8 meters in 1 second

To find the rate at which the amount of seed decreases.

11 1/4 ounces = 5 days

Dividing both sides of the equation by 5.

11 1/4 ounces = 1 day

Multiplying 7 on both sides to get the number for 7 days

7 x 11.25 ounces = 7 days

78.75 ounces  = 7 days

If the amount of seed in a bird feeder decreases by 11 1/4 ounces in 5 days, the amount of seed decreases by 78.75 ounces.

If the total cost to rent 2 chairs and 12 tables is $107 and the total cost to rent 5 chairs and 3 tables is $38, then the costs to rent each chair and table are $2.5 and $8.5 respectively. We can solve this question using elimination and substitution methods.

Elimination and substitution methods are involved in solving this problem. We're going to use the variables x for the cost of a chair and y for the cost of a table. The total cost to to rent 2 chairs and 12 tables is $107, so the equation can be written as 2x + 12y = 107. The total cost to rent 5 chairs and 3 tables is $38, so the equation can be written as 5x + 3y = 38.

To find the value for x, we need to eliminate the variable y first. Start by multiplying each term in the second equation by 4.

5x · 4 + 3y · 4 = 38 · 4

20x + 12y = 152

Then, subtract the terms in the second equation from their counterparts in the first equation.

2x   + 12y = 107

20x + 12y = 152 -

-18x  + 0   = -45

Finally, with a little bit of algebraic manipulation, we've got x = 2.5, hence $2.5 is the cost in to rent a chair.

-18x = -45

x = -45/-18

x = 2.5

What about the cost to rent a table? Well, we can substitute 2.5 for x in either of the equations to get the value for y. For instance, we can pick the equation 2x  + 12y = 107 and substitute x with 2.5 to isolate the variable y, like this:

2(2.5) + 12y = 107

5 + 12y = 107

12y = 107 - 5 = 102

y = 8.5

The value for y turns out to be 8.5. So the cost to rent a table is $8.5.
