If the function y = sinx is transformed to y = 3 sine (two-thirds x), how do the amplitude and period change?

Mathematics

Change in Amplitude is 2

Change in Period is π

Transforming sin(x) to 3sin(\frac{2x}{3})

y = a(sin(bx+c)) + d

Where, a is Amplitude and \frac{2}{b}π is period

Amplitude of sin(x) =1

Period of sin(x) = 2π

Amplitude of 3sin(\frac{2x}{3}) = 3

Period of 3sin(\frac{2x}{3}) = \frac{2}{\frac{2}{3}}*π = 3π

Change in Amplitude = 3sin(\frac{2x}{3}) - sin(x)

                                    = 3 - 1

                                    = 2

Change in Period = 3sin(\frac{2x}{3}) - sin(x)

                              = 3π - 2π

                               = π

Answer:

x = \frac{ab}{b+a}

Step-by-step explanation:

Given

\frac{x}{a} + \frac{x}{b} = 1

Multiply through by ab to clear the fractions

bx + ax = ab ← factor out x from each term on the left side

x(b + a) = ab ← divide both sides by (b + a)

x = \frac{ab}{b+a}

Jill weighs 120 pounds and is gaining ten pounds each month. Paris weighs 150 pounds and is gaining 4 pounds each month. How man
lyudmila [28]

Answer:

5 months

Step-by-step explanation:

To solve this problem, we need to create and algebraic equation for when Jill's weight will be equal to Paris's. If we take their current weight and then add the additional weight gain per month times the number of months, we can calculate the amount of time it will take for their weight to be equal by solving for m.

120+10m=150+4m\\10m-4m=150-120\\6m=30\\m=5

Claire accepted a new job at a company with a contract guaranteeing annual raises. Let S
TiliK225 [7]

Answer:

6 years

Step-by-step explanation:

First, you need to write an equation for this problem. I'll write it in slope intercept:

y = mx + b

where m is the slope and b is the y-intercept

To find m, do (change in y/change in x):

using (2, 59000) and (5, 72500),

(72500 - 59000) / (5 - 2)

= 13500 / 3

= 4500

So we have y = 4500x + b

To find b, plug in one of the points into the equation with the slope:

using (2, 59000),

y = 4500x + b

59000 = 4500(2) + b

59000 = 9000 + b

50000 = b

So now you have an equation: y = 4500x + 50000. Now that there is an equation, just insert the given y-value and solve:

when y = 77000

y = 4500n + 50000

= 77000 = 4500x + 50000

= 27000 = 4500x

= 6 = x

So, when Claire's Salary is 77000, her number of years at the company is 6.
