Answer:
The first one: A shape is a rectangle if and only if the shape has exactly four sides and four right angles.
Step-by-step explanation:
The true statement is the first one:
A shape is a rectangle if and only if the shape has exactly four sides and four right angles.
11^0 is 1.
11^2= 121
121/1= 121
Final answer: 121
So 0.25 is essentially 25/100. Divide 25 from the top and bottom to get 1/4
Let's take as example a linear function of the form:
y = kx.
Where,
k is the constant of proportionality.
Therefore, the proportionality constant is the point:
(x, kx)
Generically it is always the point:
(x, k * f (x))
Where, f (x) is a function proportional to x.
answer:
The constant of proportionality is always the point (x, k * f (x)), where k is the constant of proportionality.
The angle that subtends a chord is half the measure of the arc, so we have an arc QS of 2(84)=168 degrees.
Answer: 168 degrees
