The dimensions of the building are (x² - 2)(5x + 4). The result is obtained by using the expression for the dimensions.

Grouping is a specific technique used to factor polynomial equations. You can use it with quadratic equations and polynomials that have four terms. The method is slightly different.

Here is how to factor by grouping:

The area of the new high school building in a rectangular shape is 5x³ + 4x² - 10x - 8. Factor by grouping to find the dimensions!

Follow the steps on how to factor by grouping.

5x³ + 4x² - 10x - 8

= (5x³ + 4x²) - (10x - 8)

= x²(5x + 4) - 2(5x - 4)

= (x² - 2)(5x + 4)

Hence, the dimensions of the building are (x² - 2)(5x + 4).

Jolene will have 4096 virus cells in her body after 12 divisions

Viruses are something more than living or dead, they are both. Maybe we need a new classification of life for them, a life that lives when the environment is favorable and hibernate when it is not.

The function provided to determine the number of virus cells in the body after h hours is 2^h. To find the number of virus cells after 12 divisions, we can plug in 12 for h in the function.

2^12 = 4096.

So, Jolene will have 4096 virus cells in her body after 12 divisions.

Please note that Jolene would not develop a rash after 12 divisions as it would take 30 divisions (120 hours) for the rash to appear.

600 g flour is needed to make the recipe which needs 150 g flour for 3 people, for 6 people.

Given that a recipe for 3 people uses 150 g of flour.

We know that the relation between quantity of flour and number of people for whom recipe will be prepared is directly proportional.

So if the number of people will increase so the quantity of flour will be needed more.

The flour needed to make the recipe for 1 people is = 150/3 = 50 g.

The flour needed to make the recipe for 6 people will be = 50 * 6 = 300 g.

Hence 600 g flour is needed to make the same recipe for 6 people.

A linear graph is one whose equation is in the form y = mx + b, where m and b are constants. A quadratic graph is one whose equation is in the form y = ax^2 + bx + c, where a, b, and c are constants.

To determine if a given graph is linear, calculate the equation of the line by finding two points on the graph and plugging them into the equation y = mx + b.

For example, if the two points on the graph are (2, 3) and (5, 7), then plugging these values into the equation gives us:

y = mx + b

3 = m*2 + b

7 = m*5 + b

Solving this system of equations gives m = 2 and b = -1, so the equation of the line is y = 2x - 1.

A quadratic graph is one whose equation is in the form y = ax^2 + bx + c, where a, b, and c are constants. To determine if a given graph is quadratic, calculate the equation of the parabola by finding three points on the graph and plugging them into the equation y = ax^2 + bx + c.

For example, if the points on the graph are (1, 6), (2, 13), and (3, 24), then plugging these values into the equation gives us:

y = ax^2 + bx + c

6 = a*1^2 + b*1 + c

13 = a*2^2 + b*2 + c

24 = a*3^2 + b*3 + c

Solving this system of equations gives a = 4, b = -5, and c = 6, so the equation of the parabola is y = 4x^2 - 5x + 6.

An exponential graph is one whose equation is in the form y = a*b^x, where a and b are constants. To determine if a given graph is exponential, calculate the equation of the line by finding two points on the graph and plugging them into the equation y = a*b^x.

For example, if the two points on the graph are (2, 16) and (3, 24), then plugging these values into the equation gives us:

y = a*b^x

16 = a*b^2

24 = a*b^3

Solving this system of equations gives a = 2 and b = 2, so the equation of the line is y = 2*2^x.

The missing angle of a triangle where only the measure of all sides are given can be calculated by using the Cosine Law .

What is Law Of Cosine ?

The law of cosine is also known as Cosine Rule. This law is useful in finding  the missing information of  any triangle.

For example, if you know the lengths of three sides of a triangle , this rule helps to find the angle between the two sides of the triangle.

Let a , b and c be the sides of the triangle and let A , B and C be the angle corresponding to the respective sides .

Then by the Cosine Law the angles are represented as : [tex]CosA = \frac{b^{2} +c^{2} -a^{2} }{2bc}[/tex] ;

According to the compound interest formula, the population is 5 years is 422,385.

The term compound interest in math is defined as the interest calculated on the principal and the interest accumulated over the previous period.

Here we have given that the population of 210,000 people is increasing by 15% each year.

And then while looking into the given question, we have identified that the value of

interest rate = 15%

principal count = 210,000

time period = 5

Here we have to convert R as a percent to r as a decimal, then we get

=> r = R/100

=> r = 15/100

=> r = 0.15 rate per year,

Now, we have to solve the equation for A

[tex]A = P(1 + \frac{r}{n} )^{nt}[/tex]

Apply the values on it , then we get,

[tex]A = 210,000.00(1 + \frac{0.15}{1} )^{(1)(5)}[/tex]

When we simplify this one then we get

[tex]A = 210,000.00(1 + 0.15)^5[/tex]

Therefore, the value of A is 422,385.

Of the part, the whole, and the percent, a. the exact number of students that are athletes is unknown to Ms. Morgan, which is 36, and b. the total strength of the students is unknown to Mr. Gregory which is 180.

Here we need to know 3 things- the total no. of students each teacher has, the percentage of athletes, and no. of students that are athletes.

a)

As we can see in the case of Ms. Morgan, we know the total strength of the students and the percentage of the students that are Athletes. Hence what we don't know here is the exact number of students that are athletes.

Hence we need to find 30% of 120

= 30/100 X 120

= 36 students.

b)

Here, in Mr. Gregory's case, we know the percentage and the actual number of students that are athletes. Hence, here we don't know the total strength of the students Mr. Gregory has.

Total strength = no. of athletes X 100/percent of athletes

= 27 X 100/15

Negative Slope can be used to describe the line representing the relationship between the number of balloons remaining and the number of hats created.

In the given question, we have to find what phrases can be used to describe the line representing the relationship between the number of balloons remaining and the number of hats created.

As we know that,

(1) Negative Slope: A line with a negative slope is one that is moving from left to right in a downward direction. The rise to run ratio of the line, in other words, is negative.

(2) Decreasing Function: For a given function, y = F(x), the function is known as an increasing function if the value of y increases as the value of x increases, and the function is known as a decreasing function if the value of y decreases as the value of x increases.

(3) Constant Slope: Small slopes correspond to low speeds, negative slopes to high speeds, and constant slopes (straight lines) to steady speeds.

Hence, Negative Slope can be used to describe the line representing the relationship between the number of balloons remaining and the number of hats created.

Step-by-step explanation:

Given

The unit cost is given by

[tex]C(x)=0.6x^2-168x+30,389[/tex]

find the derivative of the unit cost and equate it to zero to obtain the minimum value

[tex]C'(x)=0.6\times 2x-168\\\Rightarrow 0.6\times 2x-168=0\\\Rightarrow 1.2x=168\\\\\Rightarrow x=\dfrac{168}{1.2}\\\\\Rightarrow x=140[/tex]

Substitute 140 for [tex]x[/tex] in the cost function, we get

[tex]C(140)=0.6[140]^2-168(140)+30,389\\C(140)=11,760-23,520+30,389\\C(140)=\$18,629[/tex]

Answer:

15.33mg

Step-by-step explanation:

Given the number of plants in a terrarium is given by the function

P(c) = -1.2c^2 + 4c + 12

At the hihest number of plants produced, dP(c)/dc = 0

dP(c)/dc = --2.4c + 4

0 = -2.4c + 4

2.4c = 4

c = 4/2.4

c = 1.67

To get the highest number of plant produced, we will substitute c = 1.67 into the original function

P(c) = -1.2c^2 + 4c + 12

P(1.67) = -1.2(1.67)^2 + 4(1.67) + 12

P(1.67) =  -3.34668 + 18.68

P(1.67) = 15.33332

Hence the amount of plant food that produces the highest number of plants is 15.33mg (round to the nearest hundredth).
