If Courtney walks 3 miles in 80 minutes, then Courtney will walk how far

ozzi

Divide 80/3 which equals 26.6. So it take Courtney 26.6 minutes to walk 1 mile. Then divide 110/26.6 which equals 4.1.

Courtney walls 4.1 miles in 110 minutes.

Faliha runs around a square field of side 70m, while Rameen runs around a rectangular field with length 90m and breadth 60m. Who

inn [45]

$\huge\sf\green{Answer :- }$

<h2>Given :- </h2><h2 />

Side of the square field = 70m

Length of the rectangular field = 90m

Breadth of the rectangular field = 60m

Perimeter of the square field

Perimeter of the rectangular field

<h2>Solution :-</h2>

Perimeter of the square = 4 × side

By substituting values,

⇒ 4 × 70m

➥ 280m

<h3><u>Hence, </u><u>Faliha</u><u> runs 280m around a Square </u><u>field</u></h3>

Perimeter of the rectangle = 2( length + Breadth)

By substituting values,

⇒ 2( 90m + 60m )

⇒ 2( 150m)

➥ 300m

<h3><u>Hence, Rameen runs 300m around a rectangular field</u></h3>

By comparing perimeters, Rameen runs more than Faliha

Distance runs more by rameen = Distance covered by rameen - distance covered by faliha

By substituting values,

⇒ 300m - 280m

➠ 20m

<h3><u>Hence, </u><u>Rameen</u><u> runs more around a rectangular field by 20</u><u>m</u></h3>

Find the limiting value using L hospital

viktelen [127]

Answer:

-1

Step-by-step explanation:

The expression evaluates to the indeterminate form -∞/∞, so L'Hopital's rule is appropriately applied. We assume this is the common log.

d(log(x))/dx = 1/(x·ln(10))

d(log(cot(x)))/dx = 1/(cot(x)·ln(10)·(-csc²(x)) = -1/(sin(x)·cos(x)·ln(10))

Then the ratio of these derivatives is ...

lim = -sin(x)cos(x)·ln(10)/(x·ln(10)) = -sin(x)cos(x)/x

At x=0, this has the indeterminate form 0/0, so L'Hopital's rule can be applied again.

d(-sin(x)cos(x))/dx = -cos(2x)

dx/dx = 1

so the limit is ...

lim = -cos(2x)/1

lim = -1 when evaluated at x=0.

_____

I find it useful to use a graphing calculator to give an estimate of the limit of an indeterminate form.

Ronnie is scheduling a chess tournament in which each player plays every other player once. He created a table and found that ea

aalyn [17]

1) According to the table represented above, the number of games that can be played when 7 players are in the tournament is definitely 21 games. As you can see, in the last row there are 4 players to 5,which means that we have 4 new games. The same happens if we go from 3 players to 4, and finelly we have 3.
<span>
2) And what about the </span>recursive rule for the original sequence, the approrpiate one is <span>an = an-1 + n - 1, so the answer is lying in the second option from the scale.
</span>According to the fact that the number of games is actually the sum of integers from 1 to n-1 we expect to have n number of players.
<span>I am sure it's clear now!
