Answer:
Step-by-step explanation:
The velocity of the arrow when it was launched upwards is 320 feet per second. The height of the platform from which it was launched is 50 ft
This means that the arrow is already 50 feets from the ground before moving upwards.
The height that it attains on moving from 50 feets will be determined by Newton's formula of motion.
v^2 = u^2 + 2as
u = initial velocity = 320 feet per second.
1 feet per second = 0.305 meters per second
320 feet per second = 320× 0.305
= 97.6 feets per second
a = acceleration due to gravity =
- 32.17405 feet/second^2 because the arrow is moving upwards)
s =maximum height of the arrow
v = final velocity = 0 feet/second
Substituting into the equation,
0^2 = 97.6^2 + 2×- 32.17405 × s
0 = 9525.76 - 64.3481s
64.3481s = 9525.76
s = 9525.76/64.3481 = 148.03 feets
Total height from the ground would be
148.03 + 50 = 198.03 feets
Answer:
Step-by-step explanation:
21+10=31-2=29
Whys u have to do is find a common denominator between 7/8 and 3/16. 8x2 equals 16 and what ever u do to the denominator u have to do to the numerator. So do 7x2 and u will get 14/16. For A it answer should be the 1st pic and the answer to number 2 is 14/16. Hope it helps! :)
Answer:
C. Four less than seven times quantity of a number plus twelve.
Step-by-step explanation:
We can see from the given expression that 4 is subtracted from 7(x+12). The term used to describe subtraction is less. So, it is 4 less than 7(x+12).
We can clearly see that the first term is x and x can take any value.
So the whole expression will be four less than seven times quantity of a number plus twelve.
Hence option C is the correct answer ..
