7 yrds/sec because in the course of two seconds, he runs 14 yrds divide that by 2 to get 7 yrds/sec. you can allo chech with the next time which is 3 seconds more and he goes 21 yards more.
First you add all given angles up to equal 180 to give you Times in to equations
A= 125 degrees
C= 35 degrees
I hope I help you and good luck
Answer:
x = 7 x = -6
Step-by-step explanation:
x^2−x−42=0
Factor
What two numbers multiply to -42 and add to -1
-7*6 = -42
-7+6 = -1
(x-7) (x+6) =0
Using the zero product property
x-7 =0 x+6 =0
x = 7 x = -6
The explicit formula of the arithmetic sequence:
d - common difference
We have the recursive formula of an arithmetic sequence:
Therefore we have:
Substitute:
<h3>Answer: aₙ = 7 - 3n</h3>
