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.

Step-by-step explanation:

.........................................

The solutions to the quadratic equation are:

x = (-9 + 3√(5)) / 2 or x = (-9 - 3√(5)) / 2

Option A is the correct answer.

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

Step-by-step explanation:

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.

Answer:

The value of x is 12 is not true.

Step-by-step explanation:

Since the line intersecting them are at a diagonal, it is not possible that the other of the lines both equal 115. Everything else in the choices is true.

Answer:

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

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
