andreev551 [17]

Answer:

D.\ y = 3\sin(2(x + \frac{\pi}{4}))

Step-by-step explanation:

Given

A = 3 --- Amplitude

C = \frac{\pi}{4} --- Right phase shift

Required

Identify the function

A sinusoidal function is defined as:

y = A\sin(B(x + C)) + D

Substitute values for A and C

y = 3\sin(B(x + \frac{\pi}{4})) + D

By comparison, only option (D) has the above format where

y = 3\sin(2(x + \frac{\pi}{4}))

Hence (D) is correct

Help me on number 12 13 14 and 15
aleksandr82 [10.1K]

12. 1.625 [terminating]; 13. 0.83 [bar notation over 3 (repeating)]; 14. 900 cm = 9 m; 15. 0.23 cm = 2.3 mm

Repeating decimals are parts of decimals that have repetitive digits; terminating decimals are decimals whose digits end.

Whether you are using Metric or Imperial, you have to determine whether you are going from a small unit to a big unit or vice versa. Then perform your operation. So, in exercise 14, the smaller unit is centimeters, so you would be going from big to small. Exercise 15 has you going from small to big.

There are centimeters in one meter, so multiply 9 by to get 900 centimeters.

There are 10 millimeters in one centimeter, so divide 2.3 by 10 simply by moving the decimal point ONCE to the left [Power of 10].

small to BIG → Division

BIG to small → Multiplication

I am joyous to assist you anytime.
