Answer:

The sine equation for the wave is;

y = 29·sin[(π/22)·(x - 11)] + 42

Step-by-step explanation:

The given wind parameters in the wind tunnel are;

The slowest speed of the wind in the wind tunnel, v₁ = 13 feet per second

The maximum speed of the wind, v₂ = 71 feet per second

The time it takes the wind to complete one cycle = 44 seconds

Therefore, we have;

The general form of the sine equation is given as follows;

[tex]y = A \cdot sin \left [B(x - C)\right ] + D[/tex]

The period, T = 44 seconds = 2·π/B

∴ B = 2·π/44 = π/22

Given that the wave starts at the slowest speed, the horizontal shift

The amplitude, A = (v₂ - v₁)/2

∴ A = (71 ft./s - 13 ft./s)/2 = 29 ft./s

The vertical shift, D = v₁ + a = 13 ft./s + 29 ft./s = 42 ft./s

D = 42 ft./s

When x = 0, sin(B·C) = -1

∴ -B × C = -π/2

∴ C = π/2 ÷ B = π/2 ÷ (π/22) = π/2 × 22/π = 11

Therefore, the sine equation for the wave is;

the sine equation for the wave is;

y = 29·sin[(π/22)·(x - 11)] + 42

Answer:

Step-by-step explanation:

Let line to be found be Line 2

Given:

Line 1

x - 5y = 15

x - 15 = 5y

Therefore slope = 1/5

Line 2

Point = (-5,7)

Slope = 1/5

Therefore: 7 = (1*-5)/5 + c

=> 7 = -1 + c

=> c = 8

Answer:

Adjacent

x = 14

Step-by-step explanation:

Find the diagram attached

Adjacent angles places side by side and can also be on the same straight line. Since 5x and x+96 are on the same straight line ans placed side by side, then the angles are adjacent.

The sum of angle on a straight line is 180 degrees, hence;

5x + x+ 96 = 180

6x = 180 - 96

6x = 84

x = 84/6

x =14

The value of x s 14

Answer: 77 degrees

Step-by-step explanation:

When looking at an arc, you use the inscribed angle theorem, which states that the measure of an inscribed angle is half of the measure of its interpreted arc. So since the measure of the arc is 154 degrees, you divide that by 2 and that will give you the measure of the angle, which is 77 degrees.

Answer:

$541.90

Step-by-step explanation:

We'll start with his regular pay, 40 hours times $10.73

10.73 x 40 = 429.20

His overtime pay is 10.73 + 1/2(10.73) = 10.73 + 5.365 = 16.095, rounded to 16.10

He worked 7 hours at the rate of $16.10/hour

16.10 x 7 = 112.70

Add the two totals together for his total pay before taxes:

429.20 + 112.70 = 541.90

Answer:

2(x+5) = 2x+10

Step-by-step explanation:

I'm assuming you can use any possible combination of two equivalent numerical expressions for your question.

2(x+5) = 2x+10

2 times x is 2x. 2 times 5 is 10. So, you get 2x+10

The distributive property of multiplication involves taking the product a certain value and another variable joined by either an addition or subtraction operator.

For instance :

a(b + c) = a×b + a×c = ab + ac

The expressions below shows distributive property of multiplication :

3(x + 5) and 3x + 15 exhibits the distributive property of multiplication.

3(x + 5)

Opening the bracket :

3×x + 3×5 = 3x + 15

Hence,

3(x + 5) = 3x + 15

Given data

Cost of artilce= $3600

Gain= 1/6 of 3600

Hence the Gain is

=1/6*3600

=0.166*3600

=$600

The Gain Percent is

Answer:

y = 1/4x + 6

Step-by-step explanation:

For the red cab:

Points on the graph: (0, 6) and (8, 8)

Slope:

m=(y2-y1)/(x2-x1)

m=(8-6)/(8-0)

m=2/8

m= 1/4

Slope-intercept:

y - y1 = m(x - x1)

y - 6 = 1/4(x - 0)

y - 6 = 1/4x

y = 1/4x + 6

Answer:

y = [tex]\frac{1}{4} x[/tex] + 6

Step-by-step explanation:

The slope can be determined by taking any two random pair of points on the red line.

For example, (0,6) and (4,7)

m = y2-y1 / x2-x1 = 1/4

Your y intercept is where your line intersects on the y axis. Here, it is at y = 6.

Now, you have the slope and y intercept to write the equation of the red cab.

y = [tex]\frac{1}{4} x[/tex] + 6

Answer:

$267.58

Step-by-step explanation:

Jameson: simple interest

6% =.06    .06 x 5 = .3   .3 x 7000 = 2,100 = interest

6% =.06    .06 x 5 = .3   .3 x 7000 = 2100   2100 + 7000 = 9,100 = total

Quincy: compound interest

6% =.06    .06 x 5 x 1 = .3 x 7000 = 2100

6% =.06    .06 x 5 x 1 = .3 x 7000 = 2100 + 7000 = 9100

.06 x 5 x 1 x 9100 = 2730 + 9100=11830

repeat five times  u would get a interest of 2,367.58

and a total of 9,367.58

the total amounts   9,367.58 - 9,100 = 267.58

the interests 2,367.58 - 2,100. = 267.58
