Answer:
center (0;0), vertices (0;10) and (0;-10), foci (0;6) and (0;-6)
Step-by-step explanation:
Answer:
300 cm * 1 m / 1,000 cm = .3 m
45 m * 1 deka / 10 m = 4.5 dekameters
900 mm * 1 cm / 10 mm = 90 cm
Step-by-step explanation:
Option C: 6 is the value of 
Explanation:
The given expression is 
We need to determine the value of 
To find the value of
, let us substitute
in the given expression.
Thus, substituting
in the expression, we have,

Adding the terms, we get,

Since, we know the absolute rule that
and the simplified expression is of the form
, let us apply the absolute rule in the simplified expression.
Thus, we have,

Thus, the value of
is 6.
Hence, Option C is the correct answer.
Answer:
-3.5 ( or -7/2)
Step-by-step explanation:
we can substitute the point into this function to find out the answer
that is:
4 = m*(-2) -3
7 = m*(-2)
m = 7 / (-2)
m = -3.5
Answer:
The height of the equilateral triangle is 
Step-by-step explanation:
we know that
An equilateral triangle has three congruent sides, and three congruent angles that each measure 60 degrees
To find out the height of an equilateral triangle, apply the Pythagoras Theorem in the right triangle ABD
Remember that the height of an equilateral triangle bisects the base.
see the attached figure to better understand the problem

substitute the given values
