Given the speeds of each runner below, determine who runs the fastest. \text{Brooke runs 13 feet per second.} Brooke runs 13 fee

Trava [24]

Answer:

Brooke runs the fastest.

Step-by-step explanation:

Brooke runs 13 feet per second.

Therefore, speed of Broke = 13 feet per sec.

Will runs 308 feet in 26 seconds.

Speed of Will = $\frac{\text{Distance}}{\text{Time taken}}$

= $\frac{308}{26}$

= 11.85 feet per second

Ron runs 1 mile in 551 seconds.

1 mile = 5280 feet

Speed of Ron = $\frac{5280}{551}$

= 9.58 feet per second

Debbie runs 658 feet in 1 minute.

1 minute = 60 seconds

Speed of Debbie = $\frac{658}{60}$

= 10.97 feet per seconds

Here, speed of Brooke is the maximum.

Therefore, Brooke runs the fastest.

Aaron and Maria collected shells one morning at the beach. Maria had 3 times as many as Aaron, but they would have the same numb

avanturin [10]

3A = M
A + 8 = M - 6
3A = M

A + 8 = 3A - 6
A + 14 = 3A
14 = 2A
A = 7

M = 3A
M = 3 x 7
M = 21

So overall Aaron had 7 shells, and Maria had 21.

Find the third fourth and fifth terms of the sequence defined by a1=1, a2=3, and a n =(-1)n a n-2 for n>3

Maslowich

We have been given that

$a_1=1\\ a_2=3\\
a_ n =(-1)^n a _{n-2} \text{ for } n>3$

In order to find the third term, we substitute n=3

$a_ 3 =(-1)^3a _{(3-2)}\\
\\
a_ 3 =(-1)^3 a _{1}$

Substituting the given value of $a_1$

$a_ 3 =(-1)^3 \times 1\\
\\
a_3=-1\times 1\\
\\
a_3=-1$

Similarly, we can find the fourth term by plugging n=4

$a_ 4 =(-1)^4a _{(4-2)}\\
\\
a_ 4 =(-1)^4 a _{2}\\
\\
a_4= 1\times 3\\
\\
a_4=3$

Therefore, the third term is -1

And the fourth term is 3
