93
Step-by-step explanation:
(-4n^(2))* (5n^(7)):-20n to the power of 9
(2x)^(3)*(5x^(4 ))^(2): 200x to the power of 11
Answer:
2 or 1
i mostly think its 2 but im not sure
Step-by-step explanation:
25 meters per second x 60 seconds = 1500 meters per minute
1500 meters per minute x 60 minutes per hour = 90,000 meters per hour
1 mile = 1609.34 meters
90000/1609.34 = 55.92 miles per hour
round answer to either 55.9 or 56 mph depending on what you need.
Answer:
2sin50 cos20
Step-by-step explanation:
We need to write sin (70) + sin(30) as a product. The formula used here is :
Here, A = 70 and B = 30
So,
So, the value of sin (70) + sin(30) is 2sin50 cos20. Hence, the correct option is (c).
