Answers:
A)
C)
Step-by-step explanation:
<u>Part 1:</u>
We have the followig equation:
Calculating the least common multiple (l.c.m) in the denominator in the left side of the equation, being l.c.m=15:
Solving for the left part of the equation:
Operating with cross product:
Applying the distributive property:
Isolating :
Dividing numerator and denominator by 11:
Hence, the correct option is A
<u>Part 2:</u>
We have the followig equation:
Operating with cross product:
Isolating :
Hence, the correct option is C
Answer:
65 degrees.
Step-by-step explanation:
Since angle JLG is 115 degrees, andgle JLH must be 65 because the two angles are supplementary, which means they add up to 180 degrees.
Part (b)
We use the result of part (a) and plug in (x,y) = (0,0). This is directly from the initial condition y(0) = 0.
-----------------
This means,
is the solution with the initial condition y(0) = 0.
Answer:
Centre: (6,0)
Radius: 2
Step-by-step explanation:
r² = 4
r = 2
Question 4 the answer is 30 degrees.
Question 5 the answer is 132 degrees because angles on a straight line equal to 180 so 180-48.
Question 6: 90+25=115, 180-115=65
Question 7: 180-149= 31
