The first tern of an arithmetic sequence is -3 and the fifteenth term id 53. What is the common difference of the sequence?

arsen [322]

The common difference is 4. U know that the formula is the first term + d(n -1). N-1 is 14 so u know that 14 times a number needs to equal 56 because the first term is -3 and 56-3 is 53. 14 * 4 is 56. So the common difference is 4

A rectangular field is 50 yards wide and 100 yards long. Patrick walks diagonally across the field. How far does he walk

S_A_V [24]

Answer:

Patrick walk approximately 112 yards.

Step-by-step explanation:

Given:

A rectangular field is 50 yards wide and 100 yards long.

Patrick walks diagonally across the field.

Now, to find the distance he walk.

Length of the field = 100 yards.

Width of the field = 50 yards.

Now, to get the diagonal distance we put formula:

$Diagonal = \sqrt{length^2+width^2}$

$Diagonal = \sqrt{100^2+50^2}$

$Diagonal = \sqrt{10000+2500}$

$Diagonal = \sqrt{12500}$

$Diagonal = 111.80$

Therefore, Patrick walk approximately 112 yards.
