Answer:
C. 178−−−√ m
Step-by-step explanation:
Given the following :
v = final velocity (in m/s)
u = initial velocity (in m/s)
a = acceleration (in m/s²)
s = distance (in meters).
Find v when u is 8 m/s, a is 3 m/s², and s is 19 meters
Using the 3rd equation of motion :
v^2 = u^2 + 2as
v^2 = 8^2 + 2(3)(19)
v^2 = 64 + 114
v^2 = 178
Take the square root of both sides :
√v^2 = √178
v = √178
Answer:
Ans = 2.53m
Step-by-step explanation:
It is a simple law of Cosine, on a right-angle triangle draw the length as 5 and the base as 7 the angle is 15°. Find x.
So x = 5² +7² - 2 (5) (7)cos 15°
Solve this and you get your answer.

i think it would be A
Step-by-step explanation:
Answer: The perimeter of Martha's wooden border = 44 feet.
Step-by-step explanation:
Given: The formula to find the perimeter = 2w + 2l. , where w = width and l = length
If l= 12 feet and w = 10 feet
Then, the perimeter of Martha's wooden border = 2(10)+2 (12) feet
The perimeter of Martha's wooden border = 20+24 feet
The perimeter of Martha's wooden border = 44 feet
Therefore, the perimeter of Martha's wooden border = 44 feet.
Answer:
is it 60$
Step-by-step explanation:
because if its 100% than it would be 40+40+40
due to 50% = 120 ÷50%
= 60
