Answer:
Option 4 is correct.
The equation 
is equivalent to 
Step-by-step explanation:'
Given equation:
First group the terms with x and those with y;
Next, we complete the squares.
We can do this by adding a third term such that the x terms and the y terms are perfect squares.
For this we must either add the same value on the other side of the equation or subtract the same value on the same side so that the equality is maintained.
⇒
or
Add 360 on both sides we get;
Simplify:
Therefore, the given equation is equivalent to
Answer:
100m race
Step-by-step explanation:
because 10.4 x 4 because 100m and 400m right 10.4x4=41.6 and 43.9 so obviously the 100m race is faster.
Answer:
0.047
Step-by-step explanation:
Given that poisson distribution with mean m, for 0.5 square meter =1.5
Then the formula for finding the probability =
P[k] = (e^-m * m^k) k!
Hence we have
P[4] =[ (e^-1.5) * (1.5^4)] ÷ 4 * 3 * 2 * 1
= (0.2231301601 * 5.0625) ÷ 24
=( 1.12944375) ÷24
= 0.04706
≈ 0.047
Hence, the final answer is 0.047

Answer:
Step-by-step explanation:
step 1
Find the value of x
we know that
r is the midpoint of qs
so
QR=RS
QS=QR+RS------> QS=2RS -----> equation A
RT=RS+ST ----> equation B
see the attached figure to better understand the problem
Substitute the given values in the equation B and solve for x
step 2
Find the value of RS
substitute the value of x
step 3
Find the value of QS
Remember equation A
QS=2RS
so
