What is the formula for the following arithmetic sequence?
vlabodo [156]

a_{n} = 12 + (- 6)(n - 1 )

This is an arithmetic sequence with n th term

a_{n} = a_{1} + (n - 1)d

here d = - 6 - 0 = 0 - 6 = 6 - 12 = -6 and a_{1} = 12, hence

a_{n} = 12 + (- 6)(n - 1)

use this formula to find the 30 th term

a_{30} = 12 + (- 6 × 29) = 12 - 174 = - 162

A ladder is leaning up against a house. The ladder is 20 feet long and the base of the ladder is 12 feet away from the house. Ho
MrRa [10]

Answer:

16 feet

Step-by-step explanation:

The length of the ladder=20 feet

Distance from the base of the ladder to the house = 12 feet

You will notice that a wall is vertical and the ladder makes an angle with the horizontal ground(making it the hypotenuse). This is a right triangle problem.

To find the how far up the house can the ladder can reach, we simply find the third side of the right triangle.

From Pythagoras theorem

Hyp^2=Opp^2+Adj^2\\20^2=12^2+Adj^2\\Adj^2=400-144\\Adj^2=256\\Adj=\sqrt{256}=16

The third side of the right triangle is 16. Therefore the ladder leans 16 feet from the ground.

Paolo is putting a fence around his pool. The length of the pool is 20 feet, the width is (20 minus x) feet, and the area of the
Nat2105 [25]

Answer:

(A) x=5

Step-by-step explanation:

  • The length of the pool is 20 feet,
  • The width is (20 minus x) feet; and
  • The area of the pool is 300 square feet.

Area = Length X Width

300 =20(20-x)

Opening the bracket on the right hand side

300 =400-20x

20x=400-300

20x=100

Divide both sides by 20

x=5

The value of x=5
