The relationship between the discriminant of a quadratic polynomial and the number of real roots is that the discriminant let us know the number and type of the solutions.

Basically for a quadratic polynomial ax²+ bx + c = 0,  the  b² - 4ac is the  discriminant.if the discriminant is greater than zero (b²- 4ac > 0), the graph intersects the abscissa twice which means it has two real solutions,  whereas if the discriminant is equal to zero ( b² - 4ac = 0), then the graph intersects once the abscissa which means it has a  single real solution and at last  if less than zero (b² - 4ac < 0), then the graph doesn't at all intersect the abscissa which, it has imaginary solutions.

Answer: 9180 mg

Step-by-step explanation:

First we must convert the patients weight from lb to kg.

102lb x [tex]\frac{0.45kg}{1lb}[/tex] = 102 x 0.45 kg = 45.9 kg

Now to calculate the amount of the drug she should receive.

45.9 kg x [tex]\frac{200mg}{kg}[/tex] = 9180 mg

We define the following variables:

• x = age (in years) of the eldest,

• y = age (in years) of the second,

• z = age (in years) of the youngest.

From the statement, we know that:

0. the eldest is 7 years older than the second → , x = 7 + y,,

1. the second is 2 older than the youngest → ,y = 2 + z,,

2. the sum of the ages 12 years from now will be 56 → x + y + z + 12 = 56 → ,x + y + z = 56 - 12 = 44,.

We have the following system of equations:

i) Replacing the second equation in the first one, we have:

ii) Summing the ages of the three daughters, we have:

iii) Equalling the last equation with the third one, we have:

Replacing the value of z in the equation of x and y, we get:

Answer

The ages of the daughters are 20, 13 and 11.

In deductive thinking, you start with a given set of rules and conditions and determine what must be true as a consequence - True

In deductive thinking, conclusions are reached based on premises that are typically taken to be true. A conclusion is based on the concordance of several premises typically presumed to be true in this logical procedure. Top-down logic is another name for deductive thinking. It only makes use of data that is believed to be reliable. It excludes sentiments, feelings, and unsupported assumptions because it is challenging to assess the integrity of this data.

Making logical assumptions and basing a conclusion on them are the foundations of deductive thinking. It enables the individual to combine the information from two or more assertions to arrive at a sound conclusion. If something is presumptively true and a different object is connected to the first presumption, then the original truth must also apply to the second. Therefore, In deductive thinking, if you start with a given set of rules and conditions and determine what must be true as a consequence holds true.

The dilated function g(x) will be g(x) = x(x + 4)(x + 2). The zeroes of function g(x) = x(x + 4)(x + 2) will be x = 0, x = - 4, x = -2. The graph of the function g(x) is attached.

Scale factor is used to compare 2 quantities, indicating by how much one quantity is greater than the other. It is denoted by K. Mathematically-

K = a/b.

If a coordinate point (x, y) is dilated by a scale factor of [k], then the coordinate point after dilation will be - (kx, ky).

Given is the function -

f(x) = (x+4)(x+2)

[A] -

For dilating the given f(x) by [x] times -

g(x) = [tex]x[/tex] f(x)

g(x) = x(x + 4)(x + 2)

Therefore, the dilated function g(x) will be -

g(x) = x(x + 4)(x + 2)

[B] -

The graph of the function g(x) is attached with the answer.

[C] -

The points where the graph of g(x) touches or cuts the x - axis, will represent the zeroes of the function g(x) = x(x + 4)(x + 2). It can be seen that the points are -

x = 0

x = - 4

x = - 2

The zeroes of function g(x) = x(x + 4)(x + 2) will be x = 0, x = - 4, x = -2.

Therefore,  the dilated function g(x) will be g(x) = x(x + 4)(x + 2). The zeroes of function g(x) = x(x + 4)(x + 2) will be x = 0, x = - 4, x = -2. The graph of the function g(x) is attached.

Answer:

48/13

Step-by-step explanation:

To make this into an improper fraction, convert the integer into a fraction using the denominator of the fraction

3 * 13/13 = 39/13

Then add it to the rest of the fraction

39/13 + 9/13

= 48/13

Answer: 48/13

Step-by-step explanation: first multiply 3 x 13 to get 39. do this because you get the fraction for the whole number, 3. then, add 39 to the numerator (9). you will get 48/13. you do this because you are adding the whole number (3) to the fraction so that way it is an improper fraction.

Answer

• a) 30.9

• Homework: 25%

• Project: 10% (each)

• Final exam: 45%

A student has:

Part A

• Homework: 86

• First project: 94

Part B

• Second project: 71

• Third project: 78

• Total grade: 80

Procedure

• a)

To know the student's grade at the point where he has an 86 homework average and 94 on the first project. We have to multiply the ponderation of each category times the grade to find the final grade (TG), meaning:

Simplifying:

• b)

Following the same procedure, now we have to multiply the ponderations of the new grades, as follows:

Next, as we are asked to find the calculations of the grade of the exam to get a final grade of 80, we have to consider the latter and the ponderation for the exam:

where x is the grade of the exam.

Solving for x:

Answer

i) 4% = 0.04

ii) 76% = 0.76

iii) 120% = 1.20

iv) 100% = 1.00

v) 32.5% = 0.325

Explanation

The key to writing percents as decimals is to divide the percents by 100 to get the decimal equivalent.

i) 4% = (4/100) = 0.04

ii) 76% = (76/100) = 0.76

iii) 120% = (120/100) = 1.20

iv) 100% = (100/100) = 1.00

v) 32.5% = (32.5/100) = 0.325

This question simply means we should find the value of x,

First we expand by using 2 to multiply the items in the bracket, we have

Hence the answer is -3.2

Part a

The altitude in miles = 6.07 miles

Part b

Head wind in miles per hour = 439.30 miles per hour

Part c

The headwind in miles per hour = 114.35 miles per hour

Part d

The temperature in degree Fahrenheit = -41.8 degrees Fahrenheit

Part a

The altitude = 9770 meters

To convert meter to miles, divide the length by 1609

Therefore,

9770 meters = 9770/1609

=6.07 miles

Part b

The ground speed = 707 km/hours

To convert km per hour to miles per hour, divide the speed value by 1.609

707 km/hour = 707/1.609

= 439.30 miles per hour

Part c

The head wind = 184 km/hour

To convert km per hour to miles per hour, divide the speed value by 1.609

184 km/hour = 184/1.609

= 114.35 miles per hour

Part d

The outside air temperature = -41 degree C

F = (9/5)C + 32

= (9/5)×-41+32

= -41.8 degrees Fahrenheit

Hence,

Part a

The altitude in miles = 6.07 miles

Part b

Head wind in miles per hour = 439.30 miles per hour

Part c

The headwind in miles per hour = 114.35 miles per hour

To find:-

The value of Q.

So now the mean of 40,50 and 90 is P. so we get,

So the value of p is 60.

Also we have the mean of 40,50,90 and P is Q. so we get,

So the value of q is 60.

To find the mean of grouped data, we need to use the next formula:

First, we need to find the midpoint of each interval:

The midpoint of interval = 1/2 (lower class limit + upper-class limit)

Then:

Time for competition (in minutes) ----- frequency ---- midpoint

9 -11 8 1/2(9+11) = 10

12 -14 7 1/2(12+14) = 13

15-17 5 1/2(15+17)= 16

18 - 20 3 1/2(18+20) = 19

21-23 3 1/2(21+23) = 22

Now, multiply the frequency of each interval by its midpoint:

10 * 8 = 80

13* 7 = 91

16 * 5 = 80

19 * 3 = 57

22 *3 = 66

Summ all the results 80 + 91 +80+57+66= 374

Then, sum all the frecuencys = 8 + 7 +5 +3 +3 = 26

The following statement "In centrally planned economies, the distribution of goods costs nothing to administer" is true.

A centrally planned economy, often known as a command economy, is an economic system in which a government agency makes economic choices affecting the production and distribution of products. Centrally planned economies vary from market economies in that these decisions are the outcome of hundreds of choices made by producers and consumers.

State-owned corporations provide goods and services in planned economies, however, independent firms may occasionally be brought into economic planning. Prices, salaries, and production schedules are often set by a centralized bureaucracy.
