Answer:
PQ ≈ 9.4 cm
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = P(- 4, - 2) and (x₂, y₂ ) = Q(4, 3)
PQ =
=
=
=
≈ 9.4 cm ( to 1 dec. place )
Answer:
Option B is correct.
y =32x represents a proportional relationship.
Step-by-step explanation:
If two quantities are said to have a proportional relationship if they vary in such a way that one of the quantities is a constant multiple of the other i.e,
y = |k| y where |k| is constant proportionality.
By definition :
y =32x where k =32 is constant , represents a proportional relationship.
Answer:
Step-by-step explanation:
8 3/5 on a number line is between 8 and nine
idk how to draw a number line on a computer so ill just tell you how
1. divided the spaces between 8 and 9 into 5 sections ( 3/5 )
2. then mark 3 of those 5 spaces and put a dot or a line at where the 3rd space ends
A little bit of trained eyeballing can help here. Let me tell you how I saw the answer without any computation.
Remember that the expansion of a squared binomial is
So, the square of a binomial has the following properties, which you can easily spot:
- It has three terms
- Two of them are perfect squares
- The third is twice the product of the two roots.
Well, in this case we do have three terms, and indeed is the square of 11x, and 1 is the square of itself. The only thing we have to check is that 22x is twice the product of 11x and 1, which is true.
So, the answer is
If you want to see some explicit calculations, just use the quadratic formula
to see that there is a double solution , and then use the formula
to come to the same conclusion.
Answer: I think it would be 7 cause if you multiply them together you get 49
