Answer:
2 second one cuz x can't be smaller than 0 because x is SQUARED
Answer:
the answer is 85° because all angles in a triangle add up to 180
so u add them both up, subtract from 180 n u get 85
The answer is C.
The question asks for the total amount of tires on all of the toy tractors.
Answer:
My sister will swing the total distance = 40 feet
Step-by-step explanation:
On the first swing my sister travels a distance of 8 feet.
In every successive swing she travels 80% of the distance of the previous distance.
So the sequence formed by the distance traveled in every swing will be a geometric sequence.
First term of the sequence 'a' = 8 feet
common ratio 'r' = 0.80
Since this sequence is an infinite geometric sequence,
Sum of this sequence =
[Since r < 1]
= 
=
= 40 feet
Therefore, my sister will cover the total distance = 40 feet
