Given parameters:
Midpoint of AB = M(3, -1)
Coordinates of A = (5,1)
Unknown:
Coordinates of B = ?
Solution:
To find the mid point of any line, we use the expression below;
and 
where 
and 
= coordinates of the mid points = 3 and -1
x₁ = 5 and y₁ = 1
x₂ = ? and y₂ = ?
Now let us input the variables and solve,
3 = 
and -1 = 
5 + x₂ = 6 -2 = 1 + y₂
x₂ = 1 y₂ = -2 -1 = -3
The coordinates of B = 1, -3
Answer:
C: A= 47 1/2
Step-by-step explanation:
You multiply the height by the base (which is on top), to get 47 and 1/2
The square root of 16 is 4
4×4=16
4*4=16
Ionic bonding is present for potassium chloride. Two opposite ions attract and for a bond called the ionic bond. On the other, sucrose has a covalent bonding where electrons are shared between atoms. Between this two bonds, ionic is the much stronger bond therefore the correct answer is the first option. Potassium chloride has a higher boiling point than sucrose.
Answer:
Step-by-step explanation:
The null hypothesis
The alternative hypothesis
At 0.02 level of significance,
the testing firm rejects the null hypothesis.
This implies that the rejection of the null hypothesis shows that there is sufficient evidence to reject a newsletter publisher who believes that 64% of their readers own a Rolls Royce.
