Answer:
+2
Step-by-step explanation:
The given equation, r = -3 + 5 sin theta, includes a sine term whose max value is +5 and whose min value is -5. We are interested in finding the max value that r can have. To obtain this, take that constant term, -3, and add teh max value of the sine function, which is +5. Net: 5 - 3 = 2.
The max value that r = -3 + 5 sin theta can take on is +2.
The answer is B 81 degrees
Answer:
t = 2 s and t = 4 s
Step-by-step explanation:
A ball is projected upward from ground level. After t seconds, it’s height in feet is a function defined by,

We need to find in how many seconds will the rocket be at a height of 128 ft above the ground.
It means,

So, it will be at a height of 128 feet at 2 second and 4 second.
The greatest common factor of 54 and 90 is 18.
