The features of the cosine function are given as follows:

The equation of the cosine function is given as follows:

y = 1/3cos(2(x - π/3)).

The cosine function is defined as follows:

g(x) = acos(b((x+c))+d.

The coefficients have these following roles:

The function oscillates between -1/3 and 1/3, hence the amplitude is of:

a = 1/3.

The period is of 2π/3 - (-π/3) = π, hence:

2π/B = π.

B = 2.

The horizontal shift is of -π/3, hence the equation is given as follows:

y = 1/3cos(2(x - π/3)).

The probability of getting two spades when two cards are drawn from the deck is 1/17.

Probability branch of mathematics the deal with the likewood of an event occouring. It is the measure of how likely it is something will happen or be the case. Probabilities expressed as a number between zero and one 00 indicates impossibility and one indicus certainity. Probability can be used to calculate the chances of certain outcome based on a state condition or data. Probability can also be used to make decision and prediction about the future.

The probability of getting two spades when two cards are drawn from a shuffled deck of cards is 3/52 x 2/51, or 1/17.

This is because there is a 3/52 chance of getting the first spade and a 2/51 chance of getting the second spade (since there is one less card in the deck).

Therefore, the probability of getting two spades when two cards are drawn from the deck is 1/17.

In mathematics, a set is considered closed if we are able to apply and complete an operation on its components while consistently receiving a component from the same set.

A set therefore either possesses closure for a given mathematical operation or it does not.

Use of real numbers is the closure property of addition. Addition of two real numbers results in areal number

The equation for a tangent to the graph of y = arcsin(x/2) at the origin is y = x.

To find the equation for a tangent to a graph at a certain point, we need to find the slope of the tangent at that point. To do this, we can use the derivative of the function. In this case, the function is y = arcsin(x/2). Using the chain rule, we can find the derivative of this function:

y' = d/dx(arcsin(x/2))

= d/dx(sin^-1(x/2))

= 1/√(1 - (x/2)^2)

Now, to find the slope of the tangent at the origin (0,0), we can plug x = 0 into this derivative:

y'(0) = 1/√(1 - (0/2)^2) = 1

So the slope of the tangent at the origin is 1. To find the equation of the tangent, we can use the point-slope form of a line:

y - y1 = m(x - x1) where,

Plugging in the values for the origin and the slope we found above:

y - 0 = 1(x - 0)

or, y = x

So the equation for the tangent is y = x. But the options are incorrect.

61.67 oz of the 55% acid solution and 33.33 oz of the 30% acid solution must be mixed to produce 100 ounces of a 43% acid solution.

This is a mixture problem that can be solved using algebra. We can set up a system of equations to represent the amount of each solution being used and the final acid concentration.

Let x be the amount of 55% acid solution and y be the amount of 30% acid solution used.

We can set up the following system of equations:

(55/100)x + (30/100)y = (43/100)(x + y) (Equation 1) represents the final acid concentration.

x + y = 100 (Equation 2) represents the total amount of solution mixed

We can solve for one variable in equation (1) by isolating it and substituting it into equation (2).

Solving for x in equation (1) we get: x = (100*43/100 - y30/100)/55/100

Substituting this value into equation (2) we get: (10043/100 - y30/100)/55/100 + y = 100

Solving for y we get: y = (100*100 - 100*43)/30 = 33.33 oz

And then substituting this value back into the equation x = (100*43/100 - y30/100)/55/100 we get x = 61.67 oz

So, 61.67 oz of the 55% acid solution and 33.33 oz of the 30% acid solution must be mixed to produce 100 ounces of a 43% acid solution.

The ordered pairs are solutions to the system of equations are (-2,1.6)

In order to determine which ordered pairs are solutions to the system of equations, you need to equate the two equations and solve for x:

y = -0.5x+0.6 and y= x+3 3/5

-0.5x+0.6 = x+3 3/5

-0.5x+0.6 = x+3.6

x+3.6 + 0.5x-0.6 = 0

1.5x + 3 = 0

1.5x = -3

x = -3/1.5

x = -2

y =-0.5x+0.6

y = -0.5(-2) + 0.6

y = 1.6

y = x + 3.6

y = -2 + 3.6

y = 1.6

The number of rocks in Willy’s collection is 30

A fraction simply means a piece of a whole. In this situation, the number is represented as a quotient such that the numerator and denominator are split

In this case, the number of rocks in Willy’s collection can be represented by x and the number of rocks in Billy’s collection is 2 2/3 times the number in Willy’s collection.

The appropriate equation to illustrate this will be:

x + 2 2/3x = 110

3 2/3x = 110

x = 110 ÷ 11/3

x = 110 × 3/11

Therefore , the solution of the given problem of surface area comes out to be  0.2083 yard square.

A surface is a measurement of how much overall space an object's surface takes up. Surface area of a three-dimensional shape is determined by the total area of its surroundings. Surface area is the term used to describe a triangular shape's entire surface area. The particular area of each face on a cube with six square faces can be added up to determine the cube's surface area. Alternately, you can get the box's dimensions by using the following formula: Surface (SA) equals twice twice twice twice. A three-dimensional shape's surface area is calculated as the sum of all the space it occupies.

Here,

Given : width : 5/6 yard

and length = 1/4 yard

To find the area = length * width

=> area = 5/6 * 1/4

The number of toys is 5 in each container.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Let x be the number of toys in each container.

Weight of one toy car = 6 pounds

Weight of the container in which toy cars shipped = 5 pounds

Weight of x toy cars = 6x

Total weight of the container when toy cars are placed = 6x + 5

Weight of one toy truck = 3 pounds

Container weight = 20 pounds

Weight of x toy trucks = 3x

Total weight of the container when toy trucks are place = 3x + 20

Given that both containers have same weight.

6x + 5 = 3x + 20

6x - 3x = 20 - 5

3x = 15

x = 5
