Answer:
The correct option is;
r = √(x² + y²)
θ = tan⁻¹(y/x)
Step-by-step explanation:
The rectangular coordinate of a complex number on the complex plane is given as (x, y)
Given that the complex number is represented by a point on the plane, we have;
The distance, r, of the point from the origin, (0, 0) is r = √(x² + y²)
The direction, θ, by which we rotate to be in line with the point on the complex number is given by tan⁻¹(y/x)

Exercice 2: Un remorqueur tire un bateau à la vitesse de 10 noeuds. La tension du câble est de 2500N, Le câble est parallèle à la trajectoire. Calculer la puissance correspondante. (Une vitesse moyenne de 1 noeud correspond à un parcours de 1 mille marin, soit 1852 m, en 1 heure. D'où : 1 noeud = 1,852 km/h = 0,514 m.S")
Répondre:
1 285 watts
Explication étape par étape:
La puissance est exprimée selon la formule;
power = travail effectué / temps
Puissance = Force * (distance / temps)
Depuis Vitesse = distance / temps
Puissance = Force * vitesse
Donné
Force = 2500N
Vitesse (en m / s) = 0,514 m / s
Obligatoire
Puissance
Remplacez la formule donnée;
Puissance = 2500 * 0,514
Puissance = 1,285Watts
Par conséquent, la puissance correspondante requise est de 1285 watts
Can someone help me solve this problem?
-1= 3 + 4×
Step-by-step explanation:
hope this helps
If the given is -1= 3 + 4x then the answer is x= -1
-1= 3 + 4x
-1-3=4x
-4=4x
To find the x divide both sides by 4.
-4/4=4x/-4
x= -1

4x+y=6
y=-4x-1
HELP ME
Answer:
No solutionStep-by-step explanation:
Given
4x+y=6 y=-4x-1Solution 1Substitute y in the first equation:
4x + (-4x - 1) = 64x - 4x =6 + 10 = 7Incorrect, therefore no solution
Solution 2Writing both equation as lines:
y = -4x + 6y = -4x - 1As we see both lines have a same slope. It means they are parallel and no intersection.

Which property of multiplication is shown by the equation 14 • y • 1 = 14y?
Group of answer choices
Associative
Distributive
Commutative
Identity
Answer:
Multiplicative identity is the property shown by this equation
Step-by-step explanation:
Multiplicative identity is explained as the product of any number and one is that number. Multiplicative identity is a property exhibited by most of the mathematical tools.
Zero and one are the numbers used to simplify equations whereas zero is called the additive identity. If we add any number with zero, it will result in the same in number.
Like that 1 is used in multiplicative identity. More simple example could be 5 ˣ 1 = 5 ., it is the multiplicative identity property

Answer:
x would equal 2 and y would equal -6 so, (2,-6)
Step-by-step explanation:
Answer:
x = 2
y = -6
Step-by-step explanation:
add the equations

The weight of bags of coffee beans at the grocery store follows a Normal distribution with a mean of μ = 7 ounces and a standard deviation of σ = 2 ounces. Suppose we pick four bags of coffee beans at random from the shelf and find their total weight, W. Which of the following statements describes the random variable W?
A. The random variable W is Normal, with a mean of seven ounces and a standard deviation of two ounces.
B. The random variable W is Normal, with a mean of 28 ounces and a standard deviation of 16 ounces.
C. The random variable W is Normal, with a mean of 28 ounces and a standard deviation of four ounces.
D. The random variable W is binomial, with a mean of 28 ounces and a standard deviation of four ounces.
E. The random variable W is binomial, with a mean of seven ounces and a standard deviation of two ounces.
Answer:
C.
Step-by-step explanation:
The random variable W is Normal, with a mean of 28 ounces and a standard deviation of four ounces.
mean of total = 7+7+7+7 = 28
Variance of total = 4+4+4+4 = 16
SD of total = sqrt(16) = 4

The solutions to the quadratic equation are:
x = (-9 + 3√(5)) / 2 or x = (-9 - 3√(5)) / 2
Option A is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Quadratic equation x² + 9x + 9 = 0.
a = 1, b = 9 and c = 9
We can use the quadratic formula.
x = (-b ± √(b^2 - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation.
Now,
Plugging in the given values.
x = (-9 ± √(9^2 - 4(1)(9))) / 2(1)
Simplifying.
x = (-9 ± √(81 - 36)) / 2
x = (-9 ± √(45)) / 2
x = (-9 ± 3√(5)) / 2
Therefore,
The solutions to the quadratic equation x^2 + 9x + 9 = 0 are:
x = (-9 + 3√(5)) / 2 or x = (-9 - 3√(5)) / 2

Malawi exports approximately 1 × 10 3 metric tons of coffee per year, and Venezuela exports approximately 3 × 10 4 metric tons of coffee per year. Approximately how many times greater is Venezuela's coffee export amount than Malawi's?
Answer:
Venezuela's export of coffee is 30 times greater than Malawi's.
Step-by-step explanation:
Malawi's exports = 1 × 10³ = = 1 × (10 × 10 × 10) = 1 × 1000 = 1000 metric tons
Venezuela's exports = 3 × 10⁴ = 3 × (10 × 10 × 10 × 10) = 1 × 10,000 = 30,000 metric tons
To find by how many times greater is Venezuela's coffee export amount than Malawi's, we will divide the former by the later.
[tex]\frac{Venezuels's\ export}{Malawi's\ export} = \frac{30,000}{1000} = 30[/tex]
Therefore, Venezuela's export of coffee is 30 times greater than Malawi's.
