An explicit formula for a sequence allows you to find the value of any term in the sequence. A recursive formula for a sequence allows you to find the value of the nth term in the sequence if you know the value of the (n-1)th term in the sequence.

Answer:

An explicit formula for a sequence allows you to find the value of any term in the sequence. ... A recursive formula for a sequence allows you to find the value of the nth term in the sequence if you know the value of the (n-1)th term in the sequence.

Which set of line segments can be used to construct a triangle? A) 2 cm, 8 cm, and 9 cm B) 3 cm, 6 cm, and 2 cm C) 5 cm, 9 cm, a
zheka24 [161]

Answer: option A is the correct answer

Step-by-step explanation:

The set of line segments that can be used is the one such that, its longest side is lesser than the semi perimeter,s[s=(a+b+c)/2] of the triangle.

If we apply this condition on the given line segments,

A) 2 cm, 8 cm, and 9 cm

s = (2+8+9)/2 = 9.5

9.5 is greater than 9cm

B) 3 cm, 6 cm, and 2 cm

s = (3+6+2)/2= 5.5

5.5 is lesser than 6. If we go on to look for the area using

Area = √s(s-a)(s-b)(s-c), it would be impossible because we would end up having square root of a negative number.

C) 5 cm, 9 cm, and 3 cm

s = (5+9+3)/2 = 8.5

8.5 is lesser than 9cm

If we go on to look for the area using

Area = √s(s-a)(s-b)(s-c), it would be impossible because we would end up having square root of a negative number.

D) 6 cm, 3 cm, and 10 cm

s = (6+3+10)/2 = 9.5

9.5 is lesser than 10

If we go on to look for the area using

Area = √s(s-a)(s-b)(s-c), it would be impossible because we would end up having square root of a negative number.

So option A is the correct answer

Patrick is keeping track of how far he jogs each morning.
katrin2010 [14]

Answer:

21:50

Step-by-step explanation:

We need to find the ratio of 420 m to 1 km.

We know that,

1 km = 1000 m

So,

The ratio becomes,

\dfrac{420\ m}{1\ km}=\dfrac{420\ m}{1000\ m}\\\\=\dfrac{42\ m}{100\ m}\\\\=\dfrac{21}{50}

So, the required ratio is 21:50.
