Answer:
Step-by-step explanation:
common difference d=3-1=2
first term a=1
an=a+(n-1)d
2n-1=1+(l-1)2
2n-1=1+2l-2
2n-1=2l-1
l=n
(i used l for number of terms)
number of terms=n

Answer: -1/2
Explanation: -4y > 2x + 4; isolate the y by dividing both sides by -4 and get:
y = -2/4x + 4; simplify
y = -1/2x + 4
In y = mx + b; m is the slope
In this case, -1/2 is the slope
B. Y=2sec(2x)
This is cuz the others don’t match the graph and only this one does.
Answer:
1/2.
Step-by-step explanation:
There are 2 quadrilaterals which have 4 congruent sides in the list: A square and a rhombus, The square is the one with four right angles.
So the required probability is 1/2.
