Solve algebraically for x 3600+1.02x<2000+1.04x

Answer:

[tex]y = 2 sin (\frac{2x- 1}{16 \pi} ) - 1[/tex]

Step-by-step explanation:

We know that the standard form of equation for the sine function is given by:

[tex]y = Asin(Bx-C)[/tex] where [tex]A[/tex] is amplitude, period is [tex]\frac{2\pi }{B}[/tex] and the phase shift is equal to [tex]Bx-C[/tex] set to zero. [tex]C[/tex] is then obtained by this equation.

Here in this problem: A is equal to 2, period=2π/B=2π/2=π, where B is equal to 2 and the phase shift is equal to 2x - 1/16 pi = 0.

[tex] y = 2 sin (\frac { 2 x - 1 } { 16 \pi} ) - 1[/tex]

To construct the sine function y = 2 × sin(2(x + π/8)) + 3, you need to consider the given amplitude, period, phase shift, and vertical shift and substitute them into the general sine equation form.

Constructing the Sine Function

To write a sine function with a given amplitude, period, phase shift, and vertical shift, we use the general form of the sine equation:

y = A × sin(B(x - C)) + D

Given the data:

Amplitude (A): 2

Period: π

Phase Shift (C): -1/8 π

Vertical Shift (D): 3

First, determine B using the formula for the period: Period = 2π / B. Since the period is π:

π = 2π / B

Solving for B, we get:

B = 2

Next, substitute A, B, C, and D into the general form:

y = 2 × sin(2(x + 1/8π)) + 3

The phase shift is negative, indicating a shift to the left. Therefore, the equation becomes:

y = 2 × sin(2(x + π/8)) + 3

Now, you have the sine function with the specified characteristics.

Answer:

Step-by-step explanation:

y-intercept is for r = 0.

We have the equation y = -3 - 7r.

Substitute r = 0:

y = -3 - 7(0) = -3 - 0 = -3

Other way.

The slope-intercept form of an equation of a line:

y = mx + b (y = mr + b).

m - slope

b - y-intercept

We have the equation y = -3 - 7r = -7r - 3. Therefore m = -7 and b = -3.

Answer:

x = 140

Step-by-step explanation:

The figure is a quadrilateral. That means it has 4 sides and more importantly for this question 4 angles. All quadrilaterals have 4 angles that add up to 360o.

You know 3 of the angles. The fourth one is x.

90 + 90 + 40 + x = 360                    Combine like terms on the left

220 + x  = 360                                  Subtract 220 from both sides.

220 - 220 + x = 360 - 220               Combine all like terms

x = 140

The coordinates for the origin of the coordinate plane is (0,0).

A Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.

The coordinate plane consists of two axes which are the two mutually perpendicular lines, the X-axis and the Y-axis respectively.

The point of intersection of these two axes is known as the origin of the coordinate plane.

For the frame of reference, we take the origin of the coordinate plane as (0,0).

Therefore, the coordinates for the origin of the coordinate plane is (0,0).

Answer:

500

Step-by-step explanation:

Given: P = 150 - T where P is passenger cars and T is trucks

10P = 7T ⇔ P = [tex]\frac{7T}{10}[/tex]

Plug in equation 2 into equation 1:

[tex]\frac{7T}{10}[/tex] = 150 - T

Solving for T, we get 500

Answer:

There would be 500 passenger cars and 350 trucks.

Step-by-step explanation:

In order to find this, we need to create a system of equations. Start by making the number of passenger cars as x and the number of trucks at y. Now the first equation can be the difference of the two.

x - y = 150

The second equation can make use of the proportion. If we multiply by the opposites we'll get the difference of 0.

7x - 10y = 0

Now we multiply the first equation by -10 and add together to solve for x.

-10x + 10y = -1500

7x - 10y = 0

-------------------

-3x = -1500

x = 500

Now we can find the amount of trucks by using either equation.

x - y = 150

500 - y = 150

-y = -350

y = 350

Answer:

1) (9, 75+360n)

2) (−9, 255+360n)

Step-by-step explanation:

(9, 75) is same as (9, 75 + 360)

so it would be (9, 435)

It can also be expressed as (-9, 75 + 180 degrees)

so (-9,255) degrees

In general, (9,75+360 n) for n≥0 represents half of the possible ways of representing the point : (9,75)  

All the polar coordinates of point p = (9, 75°) are p(2.329, 8.693), p(-2.392, 8.693), p(-2.392, -8.693) and p(2.392, -8.693).

Coordinate is basically point on a surface which shows the position of point on the surface. It is like (x,y) in which x is the point on x axis and y is the point on y axis?

We know that x coordinate is r cosΘ and y=r sin Θ. and we have to first find the x coordinates and y coordinates.

The polar coordinates of point p:

1. p(9cos75, 9sin75) = p(2.329, 8.693)

2. p(9cos(180i - 75), 9sin(180 - 75)) = p(-2.392, 8.693)

3. p(9(cos(180 + 75), 9sin(180 + 75)) = p(-2.392, -8.693)

4. p(9cos(360 - 75), 9sin(360 - 75)) = p(2.392, -8.693)

Hence all the polar coordinates of point p = (9, 75°) are p(2.329, 8.693), p(-2.392, 8.693), p(-2.392, -8.693) and p(2.392, -8.693).

Answer:

f(-4) = 10.636

Step-by-step explanation:

In this problem we need to substitute and add together the remaining terms

f(x)=6−2+2e−0.3x

If we simplify

f(x) = (6−2) +2e−0.3x

f(x) = (4) +2e − 0.3x

We substitute the value for e (Euler's number)

e = 2.718

f(x) = (4) +2(2.718) − 0.3x

f(x) = (4) + 5.436 − 0.3x

f(x) = 9.436 -0.3*x

We just need to substitute for x = -4  ,  to get f(-4)

f(-4) = 9.436 -0.3*(-4)

f(-4) = 9.436 + 1.2

f(-4) = 10.636

4/8 simplifies to 1/2. Multiply 1/2 by 100 to get 50%. Thus, 4/8 expressed as a percent is 50%.

To express 4/8 as a percent without dividing, first, recognize that 4/8 simplifies to 1/2 by dividing both the numerator and denominator by their greatest common divisor, which is 4.

Then, to convert 1/2 to a percent:

1. Multiply 1/2 by 100 to express it as a percentage.

  (1/2) × 100 = 50.

So, 4/8 as a percent without dividing is 50%.

Steps:

1. Simplify 4/8 to 1/2.

2. Multiply 1/2 by 100 to convert to a percent.

  (1/2) × 100 = 50.

Therefore, 4/8 equals 50% without dividing.

Answer:

A) The worker is paid S= $ 1110 for producing 18 units.

B) The worker is paid $3,330 for producing x= 50 units.

Step-by-step explanation:

a) given x = 18 units

Time required T(x) = 4x+2

                               = 4(18)+2

                               = 72 +2

                               = 74 hrs

Amount paid S(T) = 15 T

                             = 15 ( 74) = $ 1110

b) Since S is given, S= $3,030

     S(T)= 15 (T)

     3030 /15= T

     202 hrs= T

Now, we can find x:

  T(x) = 4(x) +2

  202 = 4x + 2

  202-2 = 4x

  200 / 4 =x

  50 = x

so, worker produces 50 units.
