a) B= x**2-4+(x-1)(x+2)
b) C= x**2+4x+(x+1)(x+4)
(pouvez vous détailler pour que je puisse comprendre svp mercii :) )

Answers

Answer:

Step-by-step explanation:

a) Pour factoriser 3x + 6, vous devez trouver deux nombres qui ajoutés donnent 6 et qui multipliés donnent 3x. Les deux nombres sont 3 et 2, donc vous obtiendrez : 3x + 6 = 3(x + 2).

b) En déduire une factorisation pour A : A = 3x + 6 + (x + 2)(6x + 8) = 3(x + 2) + (x + 2)(6x + 8) = (x + 2)(3 + 6x + 8) = (x + 2)(9x + 10).

2)a) Pour factoriser B = x**2 - 4 + (x - 1)(x + 2), vous devez trouver deux nombres qui ajoutés donnent x**2 - 4 et qui multipliés donnent (x - 1)(x + 2). Les deux nombres sont x - 1 et x + 2, donc vous obtiendrez : x**2 - 4 + (x - 1)(x + 2) = (x - 1)(x + 2).

b) Pour factoriser C = x**2 + 4x + (x + 1)(x + 4), vous devez trouver deux nombres qui ajoutés donnent x**2 + 4x et qui multipliés donnent (x + 1)(x + 4). Les deux nombres sont x + 1 et x + 4, donc vous obtiendrez : x**2 + 4x + (x + 1)(x + 4) = (x + 1)(x + 4).

Answers

The final function after transformations, is [tex]f(x +8) = \sqrt[3]{x+8} - 3[/tex]

The technique of altering an existing graph or graphed equation to create a different version of the following graph is known as graph transformation. The modification of algebraic equations is a typical form of algebraic problems. Sometimes graphs are translated, or moved about the xy-plane; sometimes they are stretched, rotated, inverted, or a combination of these transformations.

Now, there are 2 different transformations applied to the function here.

First Transformation:

[tex]f(x) = \sqrt[3]{x}[/tex] is translated 3 units in the negative y direction.

After transformation, the function is [tex]f(x) = \sqrt[3]{x} - 3[/tex].

Second Transformation:

The function [tex]f(x) = \sqrt[3]{x} - 3[/tex] is translated 8 units in the negative x direction.

After transformation, the function is [tex]f(x +8) = \sqrt[3]{x+8} - 3[/tex].

Answers

The coordinate of a point whose distance from both P and Q is exactly 13 is; (15, 24)

Pythagorean theorem:

According to the Pythagorean theorem, in a right triangle (90 degrees), the square of the hypotenuse equals the sum of the squares of the other two sides. Consider the following triangle ABC where BC2 = AB2 + AC2. where AB is the base, AC is the height (height), and BC is the hypotenuse.

The coordinate of a point whose distance from both P and Q is exactly 13 is; (15, 24)

The distance between points, P and Q can be evaluated by the Pythagoras theorem as follows;

Distance, PQ = √(20-10)² + (36-12)²

PQ = √(100+576)

PQ = √676

PQ = 26.

Therefore, a point whose distance from both P and Q is exactly 13 is the midpoint of PQ.

Therefore,

a. 90 miles

b. 246 miles

Answers

The car consumes 3 gallons and 8.2 gallons of fuel respectively.

Milage:

Divide the distance traveled by the amount of gas used. For example, driving 100 miles with a full tank and 5 gallons of gas is 10mpg. When it comes to fuel economy, it's important to know how much your car is costing you each time we drive it.

According to the Question:

The gas mileage is the number of miles that can be covered by a car for a particular amount of fuel.

We are given that the gas mileage of the car is 30 miles per gallon, that means that the car consumes 1 gallon of fuel for each 30 miles covered.

The amount of fuel needed to cover the following distance is:

a) For 90 miles, let x represent the number of gallon of fuel. Hence:

Distance covered / amount of fuel = 30 miles per gallon

  90/x = 30

⇒ x = 90/30

⇒ x = 3 gallons

b) For 246 miles, let x represent the number of gallon of fuel. Hence:

Distance covered / amount of fuel = 30 miles per gallon

⇒ 246/x = 30

⇒ x = 246/30

⇒ x = 8.2 gallons

Therefore, the car consumes 3 gallons of fuel for 90 miles and 8.2 gallons for 246 miles.

Answers

The absolute value inequality for the hearing range of each animal is mod(e - 6008) ≤ 5992 and mod(m - 46000) ≤ 45000, respectively.

An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative. You can write an absolute value inequality as a compound inequality. This holds true for all absolute value inequalities. You can replace > above with ≥ and < with ≤.

To solve absolute-value inequalities, first, we must drop the absolute-value bars and restate the inequality in one of two ways, depending on the case.

According to the question,

The elephant can hear: 16 ≤ e ≤ 12000

The avg hearing = (12000 + 16)/2 = 6008

Tolerance = 12000 - 6008 = 5992

Therefore, the value absolute value inequality for the hearing of the elephant is mod(e - 6008) ≤ 5992.

Similarly,

The mouse can hear: 1000 ≤ e ≤ 91000

The avg hearing = (12000 + 91000)/2 = 46000

Tolerance = 46000 - 1000 = 45000

The coordinates of the orthocenter of the triangle J(3,-2) K(5,6) L(9,-2) are (5, -2).

What is an orthocenter?

Generally, The orthocenter of a triangle is the intersection of the lines that contain the altitudes of the triangle.

To find the coordinates of the orthocenter, we first need to find the equations of the lines containing the altitudes.

To find the equation of the altitude from vertex J, we need the coordinates of J, K, and L.

Using the given coordinates, we have J(3,-2), K(5,6), and L(9,-2).

The equation of the line containing the altitude from J is:

-2 = (-2-6)/(3-5) (x-5) + 6

The equation of the line containing the altitude from K is:

6 = (-2-6)/(5-9) (x-9) - 2

The equation of the line containing the altitude from L is:

-2 = (6-(-2))/(5-3) (x-3) + 2

Solving the equation of the line containing the altitude from J and L, we get the x-coordinate of the orthocenter is 5 Solving the equation of the line containing the altitude from K and L, we get the y-coordinate of the orthocenter is -2

1+ 4(3x - 10) 12x equivalent to -39?

Answers

To check if the equation "1 + 4(3x - 10) = 12x - 39" is true, we can substitute a value for x and see if both sides of the equation are equal.

One way to solve this equation is to first simplify the expression on the left side of the equation:
1 + 4(3x - 10) = 1 + 4(3x) - 4(10) = 1 + 12x - 40

Now we have:
1 + 12x - 40 = 12x - 39

Subtracting 12x from both sides:
-11x + 41 = - 39

Subtracting 41 from both sides:
-11x = -80

Finally, dividing both sides by -11:
x = 7.27

So, x = 7.27 is a solution of the equation and the equation is true.

The profit in 1973 is 5.56 which is estimated by the given linear model.

What is the regression equation?

The regression equation is used to predict or estimate the value of the response (or dependant) variables based on an understanding of the explanatory (or predictor) variables.

Let Y represent the profit (or loss) for a certain company X years after 1970. Based on the data shown, a statistician calculates a linear model

Y = -0.80X + 7.96 ....(i)

Using the above model to estimate the profit in 1973

Substitute the value of X = 3 in the equation (i),

Y = -0.80(3) + 7.96

Y = -2.4 + 7.96

Y = 5.56

This is the profit in 1973.

a card dealer lays out five cards, face down, from a single deck of 52 cards. what is the probability that at least one of them is an ace?

Answers

The probability that at least one person receives exactly one aces in their 52 cards is 4/52= 1/13

We define the following events:

A: person A receives exactly two aces in their five cards.

B: person B receives exactly two aces in their five cards.

C: person C receives exactly two aces in their five cards.

We need to calculate P(A∪B∪C). According to the principle of inclusion and exclusion:

P(A∪B∪C)= P(A)+P(B)+P(C)-P(A∩B)-P(A∩C)-P(B∩C)+P(A∩B∩C)

Total outcomes is equal to  because there 52 cards and we select 5 of them.

The probability of each event is given by:

P(A)=P(B)=P(C)===0.0399

where the possible outcomes are 2 aces and 3 of the other cards.

Then, the intersections of the events mean that one player gets 2 aces and the other gets 2 aces too.

P(A∩B)=P(B∩C)=P(A∩C)==0.0001

Finally,

P(A∩B∩C)=0 because it is not possible that the three events occur at the same time due to there are only 4 aces.

P(A∪B∪C)= 0.0399+0.0399+0.0399-0.0001-0.0001-0.0001+0

P(A∪B∪C)=0.1194

The probability that at least one person receives exactly two aces in their five cards is 0.1194.

b. Predict the number of students who were learning English in California in 2001.

c. Predict the number of students who were learning English in California in 2010.

please show all work

Answers

Answer:

a. To find the equation for the median-fit line, we need to first determine the slope (m) and the y-intercept (b) of the line. We can use the following formulas to calculate these values:

m = (nΣxy - ΣxΣy) / (nΣx^2 - (Σx)^2)

b = median y - m(median x)

Where n is the number of data points, x is the independent variable (year), y is the dependent variable (number of students learning English), Σ means to sum, and xy represents the product of x and y.

For this dataset, we have 5 data points, so n = 5.

x = 2003, 2004, 2005, 2006, 2007

y = 1.600, 1.599, 1.592, 1.570, 1.560

Σx = 10,015

Σy = 7,966

Σxy = 31,948

Σx^2 = 40,307

m = (531948 - 100157966)/(5*40307 - 10015^2) = -0.007

median x = 2005

median y = 1592

b = 1592 - -0.007 * 2005 = 1597.014

The equation for the median-fit line is:

y = -0.007x + 1597.014

b. To predict the number of students who were learning English in California in 2001, we can substitute 2001 for x in the median-fit line equation:

y = -0.007(2001) + 1597.014 = 1600.087

c. To predict the number of students who were learning English in California in 2010, we can substitute 2010 for x in the median-fit line equation:

y = -0.007(2010) + 1597.014 = 1590.028

Answers

The total cost of the bridge will be (200/2) × 8 × 1000 + 50 × 10 + 500 = $90,000.

The formula for calculating the cost of a bridge is Cost = (Area of Bridge/2) × Unit Weight of Steel × Unit Price of Steel + Cost of Labor + Cost of Other Materials. By using this formula, we can determine the total cost of the bridge by considering the area of the bridge, the weight of the steel used, the price per unit of steel, the cost of labor, and the cost of other materials. For example, if the area of the bridge is 200m^2, the unit weight of steel is 8 tonnes/m^3, the unit price of steel is $1000/tonne, the cost of labor is $50 per hour, and the cost of other materials is $500, then the total cost of the bridge will be (200/2) × 8 × 1000 + 50 × 10 + 500 = $90,000. Thus, by using this formula, we can easily calculate the cost of the bridge and understand why local politicians are dragging their feet in building a new bridge.
