Answer:
<em>Hence, it will take</em><em> 9 seconds </em><em>for kirk to run </em><em>63+9=72 yards </em><em>and catch upto Max. </em>
Step-by-step explanation:
Let 'y' represents the time Max and Kirk took to meet.
Let the distance between the destination where they will meet from the place where Max is be: x yards
So the distance of destination from initial position of kirk is x+9 yards ( As Max is given a head start of 9 yards)
- As speed of Max is 7 yards per sec.
And
Hence,
- also speed of kirk is 8 yards per second.
By the similar definition of speed we have:
Hence (1) and (2) are the required system of equation.
So on solving the system of equations by elimination method we have:
y=9 and x=63.
Hence, it will take 9 seconds for kirk to run 63+9=72 yards and catch upto Max.
Answer:
no
Step-by-step explanation:
Establish the nth term formula
There is a common difference d between consecutive terms, that is
d = - 5 - (- 9) = - 1 - (- 5) = 3 - (- 1) = 7 - 3 = 4
This indicates the sequence is arithmetic with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 9 and d = 4 , then
= - 9 + 4(n - 1) = - 9 + 4n - 4 = 4n - 13
Equate 4n - 13 to 301
4n - 13 = 301 ( add 13 to both sides )
4n = 314 ( divide both sides by 4 )
n = 78.5
Since n is not an integer then 301 is not in the sequence
