Answer:
As m decreases value of the given expression 
also decreases because the value of the given expression depends only on the value of m.
Step-by-step explanation:
Given expression is
<h3>To check what happens to the value of the expression m-10 as m decreases :</h3>
From the given expression
we have that as m decreases value of the given expression also decreases because the value of the given expression depends only on the value of m
Ok, so this is a sum of aruthmetic sequence and also use some logic
it goes 10 feet down, then 5 up, 5 down, etc (see attachment)
so the total distance is the sum of all the numbers in the sequence doubled, minus the first term (since it didn't bounce 10 feet up, it started from top)
the sum of an aruthmetic is
Sn=
where a1=first term, r=common ratio and n=which time
first term=10
common ratio is 0.5
n=4
so
2[
]-10=answer27.5
the answer is 27.5 feet
<h2>○=> <u>Correct option</u> :</h2>
<h3>○=> <u>Steps to derive correct option</u> :</h3>
Angle 1 and angle 3 are vertically opposite angles.
We know that :
▪︎ Vertically opposite angles are always equal.
Which means :
Angle 1 = Angle 3
Thus, the measure of angle 3 = 70°
▪︎Therefore, the correct option is (D) 70
if the sequence goes on without any changes
it will be d+8a
Answer:
