Answer:
y=2
because 4x2 =8 then 8-4 equals to 4 which is what your trying to get
We know that
area of triangle=b*h/2
b=(x-2) m
Area=(x²-4) m²
h=?
(x²-4)=(x+2)*h/2
but remember that
(x²-4)=(x+2)*(x-2)
so
subsititute
(x+2)*(x-2)=(x+2)*h/2
(x-2)=h/2
h=2*(x-2)
the answer is
<span>the height of a triangle is 2*(x-2)</span>
Answer:
B. 12.5
Step-by-step explanation:
We have the lowe confidence interval = 185
The upper confidence interval = 210
Mean of X = (lower confidence + upper confidence interval)/2
Mean of X = 185 + 210/2
= 197.5
The margin of error = the upper confidence interval - mean of X
= 210-197.5
= 12.5
The answer is: B. Even function.
The explanation for this exercise is shown below:
1. You must substitute 
with 
in the function:
2. As you can see, 
, therefore it is an Even function.
