Answer:
x = √(w(w+z))
Step-by-step explanation:
The idea with a right-triangle figure of this sort is that all of the triangles are similar. Here, x is the short side of ∆ABC, and the hypotenuse of ∆BDC. This suggests you want to write a similarity statement involving the short side and hypotenuse.
BC/AC = DC/BC . . . . . short side/hypotenuse
BC² = AC·DC . . . . . . cross multiply
x² = (w+z)w . . . . . . substitute letter values
Taking the square root and rearranging to the form of the applicable answer choice, this is ...
[tex]\boxed{x=\sqrt{w(w+z)}}[/tex]

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")
Answers
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

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.

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

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

Answer:
a) The vertex will be at (-2, -1), and the parabola will look like a smiley face. 5 points on the parabola would be: (3, 24), (-3, 0), (2, 15), (-1, 0) and (1, 8).
b) The focus will be at (-2, 0), the directrix will be at y = -2, and the axis of symmetry will be at x = -2.
Step-by-step explanation:
a) The vertex (-2, -1) can be found by first setting the parentheses (x+2) equal to zero and solving to get the x value -2, then setting x equal to zero and solving to get the y value of -1.
The parabola will be pointing up on both ends because the equation for it is positive (given 1 multiplied by parentheses) and it has a degree of 2.
The xy table to find the points would look like this:
x | y
3 | 24
-3 | 0
2 | 15
-1 | 0
1 | 8
b) The focus is one unit above the vertex, so the y value increases by 1. The directrix is a line 1 unit below the vertex, so its y value is 1 less than the vertex's. The axis of symmetry is the same as the x value of the vertex with infinite y values.
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?
Answers
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.
