Answer:
Correct option is A.
Step-by-step explanation:
Given the following functions we have to choose the option which illustrates a change in amplitude.
Multiplying a sine or cosine function by a constant changes the graph of the parent function i.e results in change in the amplitude of function. Amplitude is the measure of distance from the sinusoidal axis to the maximum or the minimum.
Option A: y = 3cos4x
The parent function is f(x) = cos x.
The amplitude of function changes from 1 to 3.
Option B: y = 1+sinx
The parent function is f(x) = sin x
The amplitude remains same i.e 1
Option C: y = -2-cos(x - pi)
Here also remains same.
Option D: y = tan 2x
The tangent function does not have an amplitude because it has no maximum or minimum value.
Hence, correct option is A.

➷ When it comes to dividing fractions, there is a rule you must now.
It's called Keep Flip Change.
I'll give you an example:
Keep the first fraction exactly as it is
Flip the second fraction upside down (switch the numerator and denominator around)
Change the sign to a multiplication.
This is how it should look:
Now you just multiply them as you normally would to get an answer of:

Answer:
3/10 of the total distance to her grandmother's house was traveled on Sunday
Step-by-step explanation:
Carly's family traveled distance of Saturday = 
Remaining distance =
They traveled 3/7 of the remaining distance on Sunday.
So, Distance traveled on Sunday =
Distance traveled on Sunday =
Fraction of the total distance to her grandmother's house was traveled on Sunday =
Hence 3/10 of the total distance to her grandmother's house was traveled on Sunday
Answer:
$27428.57
Step-by-step explanation:
To solve this problem, we can use the formula for compound interest:
P = Po * (1 + r)^(t)
Where P is the final value, Po is the inicial value, r is the rate of interest, t is the time.
With r = 0.06, t = 4 (The rate is for every 15 days, and the time is 2 months, so we have that 2 months = 4 periods of 15 days) and P = Po + 7200, we have:
Po + 7200 = Po * (1 + 0.06)^4
Po + 7200 = Po * 1.2625
Po * 0.2625 = 7200
Po = 7200 / 0.2625 = $27428.57
