Hence , the graph of the equation is y = 1.5 sin(x - 2π/3) + 3 is given below .

The general form of a sine function is of the form:

y = a×sin(bx − c) + d,

here the amplitude is a,

the period is 2π/|b|,

the phase shift is c/b, and

the vertical shift is d.

From the given equation we have,

The amplitude, a = 1.5

The period, = 2π/|1| = 2π

The phase shift = (2π/3)/1 = 2π/3

And the vertical shift is d = 2

The given equation can be graphed using the amplitude, period, phase shift, vertical shift, and points.

  x = 11°

Step-by-step explanation:

You want to know the value of x given a triangle with exterior angles 147°, 4x, and an interior angle of x at the third vertex.

The exterior angle of the triangle at B is the supplement of x: 180°-x. The sum of the exterior angles of a polygon is 360°, so we have ...

  147° +4x +180° -x = 360°

Collecting terms, we have ...

  327° +3x = 360°

  3x = 33° . . . . . . . . . subtract 327°

Answer: y=3.75x+1.9

Step-by-step explanation: the pick up fee would be the y-intercept and the per mile cost would be the slope.

The equation that can be used to determine the number of miles in the taxi ride is 1.90 + 3.75x = 80.65.

The number of miles traveled is 21 miles.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Pick up fee charges = $1.90

Charges per mile = $3.75

Total fare = $80.65

The number of miles traveled = x

We can write an equation as:

1.90 + 3.75x = 80.65

The number of miles traveled:

1.90 + 3.75x = 80.65

Subtract 1.90 on both sides.

1.90 + 3.75x - 1.90 = 80.65 - 1.90

3.75x = 78.75

Divide both sides by 3.75.

x = 21.

Thus,

The equation that can be used to determine the number of miles in the taxi ride is 1.90 + 3.75x = 80.65.

The number of miles traveled is 21 miles.

An ordered pair is a composition of the x coordinate and the y coordinate, having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension.

Ordered pairs are often used to represent two variables. When we write (x, y) = (7, - 2), we mean x = 7 and y = - 2. The number which corresponds to the value of x is called the x-coordinate and the number which corresponds to the value of y is called the y-coordinate.

see attachment for the table

we observe from the given table that

As x increases by 2, y decreases by 4

As x decreases by 2, y increases by 4

for example x = 10, y = -12

when x decreases by 2 (to 8), the value of y will increase by 4 (to -8).

Hence, the value of y when x = 8 is -8

Step-by-step explanation:

The population density of otter, raccoon, fox and bobcat is 0.3125, 1.66, 0.0803 and 0.0267 per acre

Total park area of the state park = 112 acres

Number of Otter = 35

Number of Raccoon = 186

Number of Fox = 9

Number of Bobcat = 3

The formula of population density is given by:

Population Density = Number of animals/Area of land

Population density of Otter in the park = 35/112 = 0.3125 Otter per acre

Population density of raccoon in the park = 186/112 = 1.66 Raccoon per acre

Population density of fox in the park = 9/112 = 0.0803 Fox per acre

Given x and y vary inversely.

The relationships between variables that are expressed as y = k/x, where x and y are two variables and k is a constant value, are known as inverse variation. According to this statement, if the value of one item rises, the value of the other quantity falls.

the value of x is  = 3, we need to find the value of y.

then when x = 5 and y = ₋4

If y varies inversely as x then:

x × y = k (for some constant c)

If (x,y) = (5,₋4) then:

5 × ₋4 = k

₋20 = k

Therefore, xy = ₋20

then, y = ₋20/x ; is the equation of y.

when x = 3, then:
