Answer: An is n+1 and A10 is 4

Step-by-step explanation:

The question is very vague and hard to answer. so A1 is -5, count up by 1 ten times, including -5, so -5, -4, ..., 3, 4. An is a just the way it changes, so it adds by one every time.

Hope this helps, it is a very vague question tho.

a(10) = -5 + (10–1)1

-5+10-1=<u>4</u>

£150 is divided between Malachy, Paul & Brian so that Malachy gets twice as much as Paul, and Paul gets three times as much

Dmitry_Shevchenko [17]

Answer:

£90

Step-by-step explanation:

Let M = Malachy's share

and P = Paul's share

and B = Brian's share.

We have three conditions:

(1) M = 2P

(2) P = 3B

(3) M + P + B = 150

Solve for B:

Substitute (2) into (3) (4) M + 3B + B = 150

(5) M + 4B = 150

Substitute (2) into (1) M = 2(3B)

(6) M = 6B

Substitute (6) into (5) 6B + 3B + B = 1 50

(7) B = 15

Solve for P:

Substitute (7) into (2) P = 3×15

(8) P = 45

Solve for M:

Substitute (8) into (1) M = 2×45

M = 90

Malachy gets £90.

An 80-m tower is supported by a guy wire attached to the top of the tower. If the wire forms an

nalin [4]

The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. The length of the wire is 81.5 meters.

The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,

Sin(θ) = Perpendicular/Hypotenuse

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The hypotenuse is the longest side of the triangle.

The length of the tower is 80 meters, while the angle of elevation is 79°. Therefore, the length of the wire will be the hypotenuse of the triangle. Therefore, the length of the wire is,

Sin(θ) = Perpendicular/Hypotenuse

Sin(79°) = 80 meter/Length of the wire

Length of the wire = 81.4973 ≈ 81.5 meters

Hence, the length of the wire is 81.5 meters.
