Answer:
- -35/3, -140/3, - 560/3, -2240/3
- 7, -28, 112, - 448
Step-by-step explanation:
<u>The terms are:</u>
<u>Given:</u>
- a₁ = a₂ + 35
- a₃ = a₄ + 560
<u>Use the nth term formula:</u>
- a₂ = a₁r
- a₃ = a₁r²
- a₄ = a₁r³
<u>Substitute:</u>
- a₁ = a₁r + 35 ⇒ a₁(1 - r) = 35
- a₁r² = a₁r³ + 560 ⇒ a₁(1 - r)r² = 560
<u>Divide the second equation by the first:</u>
- r² = 560/35
- r² = 16
- r = √16
- r = ± 4
<u>Use the first equation to find the first term:</u>
- a₁( 1 ± 4) = 35
- 1. a₁ = 35/-3 = -35/3
- 2. a₁ = 35/5 = 7
<u>We have two sequences:</u>
r = 4
- -35/3, -140/3, - 560/3, -2240/3
r = -4
Both 2.5 and -2.5 have absolute values of 2.5. Some nubmers that have a greater absolute value are 3.0, -3, 4.0, -4.
Answer:
x=30°
Step-by-step explanation:
total angles on a straight line=180°
4x+2x=180°
6x=180°
x=180°/6
:.x=30°.
Answer:
Step-by-step explanation:
The area of the rectangle can be calculated using formula
Since the tent has a base measuring 3 metres long and 250 centimetres wide, then the length is 3 m and the width is 2 m 50 cm or 2.50 m.
Thus, the area is
