Answer:
(1,0) would be the correct answer.
Step-by-step explanation:
any point that is reflected across y=x will change unless it is on the line. if reflected across y=x, the coordinates will become y,x
Answer:
0.45
Step-by-step explanation:
9/20 is the same as 0.45
Answer:
23.7m
Step-by-step explanation:
Given parameters:
Time taken = 2.2s
Acceleration due to gravity = 10m/s
Unknown:
Depth of the well = ?
Solution:
To solve this problem, we simply apply one of the motion equations;
S = ut +
gt²
where S = depth of the well
u = initial velocity
t = time taken
g = acceleration due to gravity
Input the parameters and solve for S;
Note initial velocity = 0;
S =
x 9.8 x 2.2²
S = 23.7m
M∠5=130 <span>and m∠4 =70
</span><span>so
m<2 = 180 - m<5
m<2 = 180 - 130
m<2 = 50
m<3 = 180 - (m<2 + m<4)
</span>m<3 = 180 - (50+70)
m<3 = 180 - 120
m<3 = 60
