The nut lands first on gorund
<em><u>Solution:</u></em>
The squirrel climbs down the tree in 2 seconds
Given that,
A squirrel is 24 feet up in a tree and tosses a nut out of the tree with an initial velocity of 8 feet per second
<em><u>The nuts height, h, at time t seconds can be represented by the equation:</u></em>
time cannot be negative, so ignore t = -1
Thus the nut takes 1.5 seconds to reach ground
From given,
The squirrel climbs down the tree in 2 seconds
Therefore, the nut lands first on gorund
Question 1)
there’s 180 degrees in a triangle
70 + 70 = 140
180 - 140= 40
A= 40
question 2)
there’s only one line of symmetry, down the middle
Answer:
-675
Step-by-step explanation:
The sum can be broken into parts that you know. Here, one of those parts is the sum of numbers 1 to n. That sum is given by n(n+1)/2.

Another way to do this is to realize the sequence of numbers is an arithmetic sequence with a first term of 65 and a last term of 67-2·75 = -83.
The sum of an arithmetic sequence is found by multiplying the number of terms by their average value. Their average value is the average of the first and last terms.
The average value of those 75 terms is (65 +(-83))/2 = -9, so their sum is ...
75(-9) = -675
