Answer 1

Answer:

a = 2, b = 1, c = - 15

Step-by-step explanation:

Se 15% de um rebanho bovino são bois e o restante são vacas, qual é o total de cabeças desse rebanho, se há 17.000 vacas?

Answers

Responder:

20.000

Explicação passo a passo:

Dado que:

Porcentagem de bois no rebanho = 15%

Percentagem de vacas = (100 - 15)% = 85%

Número de vacas = 17.000

Por isso,

85% = 17.000

15% = x

Multiplicação cruzada

0,85x = 17.000 * 0,15

0,85x = 2550

x = 2550 / 0,85

x = 3000

Número de bois no rebanho = 3000

Portanto, número total de gado no rebanho =

3000 + 17000 = 20.000

Check if (1,6) is the solution to the system shown below.

Answers

Answer:

NO it is not

Step-by-step explanation:

To check that, we will need to substitute the value of each of the coordinates in each of the equations

10x-y = -6

substitute 1 for x and 6 for y

we have this as;

10(1)-6 = 4

Outrightly, we can see that the given point is not a solution to the given system of equations

however, let us confirm for the second

We have this as;

-10(1) + 5(6)

= -10 + 30 = 20

so we can confirm that it does not work for any of the two and our answer is NO

What type of sequence is this:

Step-by-step explanation:

the common d/ce is four but not common ratio

The type of Sequence from [tex]a_1[/tex] = 2 and [tex]a_n[/tex] = [tex]a_{n-1}[/tex] + 4 is Arithmetic and recursive.

What is Arithmetic Sequence ?

In algebra, an arithmetic sequence is a set of numbers whose every two consecutive terms have the same difference.

An arithmetic sequence is one in which each phrase grows by adding or removing a certain constant, k. In a geometric sequence, each term rises by dividing by or multiplying by a certain constant k.

For example in the arithmetic sequence 3, 9, 15, 21, 27, the common difference is 6.

Given:

[tex]a_1[/tex] = 2

[tex]a_n[/tex] = [tex]a_{n-1}[/tex] + 4

We know that the Arithmetic Sequence is of two forms

Explicit Form : [tex]a_n[/tex] = a+ (n-1)d

and, Recursive form: [tex]a_n[/tex] = [tex]a_{n+1}[/tex] + d

Now, we have [tex]a_n[/tex] = [tex]a_{n-1}[/tex] + 4 which is in the form of Recursive.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

x² + 5x = 0   be equation (1)

Now , on simplifying the equation , we get

On factorizing the equation , we get

Taking the common factor x ,

x ( x + 5 ) = 0

Now , x can take 2 values which will satisfy the given equation

when x = 0 or ( x + 5 ) = 0

when x = 0

Substitute the value of x in the equation , we get

0 ( 0 + 5 ) = 0

0 = 0

The equation is true when x = 0

And ,

when ( x + 5 ) = 0

Subtracting 5 on both sides of the equation , we get

x = -5

when x = -5

-5 ( -5 + 5 ) = 0

-5 x 0 = 0

0 = 0

The equation is true when x = -5

Hence , the solution is 0 , -5

A sphere has a surface area of 803.84 cm^2. What is the volume?

Answers

Answer:

V≈2143.03cm³

Step-by-step explanation:

The volume of the sphere is 2143.57 cm³.

What is the surface area of the sphere?

A = 4 × π × r², where 'r' is the radius of the sphere.

What is the volume of the sphere?

V = (4/3) × π × r³

For given example,

a surface area of the sphere is 803.84 cm^2.

⇒ A = 803.84 cm²

Using the formula of the surface area of the sphere,

⇒ 4πr² = 803.84

⇒ r² = 64

⇒ r = 8 cm

Using the formula of the volume of the sphere,

⇒ V = (4/3) × π × r³

⇒ V = (4/3) × 3.14 × 8³

⇒ V = 2143.57 cm³

Therefore, the volume of the sphere is 2143.57 cm³.

Two birds sit at the top of two different trees. The distance between the first bird and a birdwatcher on the ground is 32 feet. The distance between the birdwatcher and the second bird is 45 feet.

A triangle is created from point Bird Watcher, point First Bird, and point Second Bird. Angle First Bird is a right angle, and angle Second Bird measures x degrees.

What is the angle measure, or angle of depression, between this bird and the birdwatcher? Round your answer to the nearest tenth.

35.4°
44.7°
45.3°
54.6°

Answers

Answer:

The correct angle is 45.3°

Step-by-step explanation:

Since the opposite side of the angle is 32 feet, and the hypotenuse of the right triangle is 45 feet, you would know that the sine of x° is equivalent to [tex]\frac{32}{45}[/tex]. To find the value of x, take the arcsin of both sides and you'll get that [tex]x = arcsin(\frac{32}{45})[/tex] ⇒ [tex]x[/tex] ≈ 45.3°.
