Answer:
a₁ = 18
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₃ = 10 and a₅₁ = - 182, then
a₁ + 2d = 10 → (1)
a₁ + 50d = - 182 → (2)
Subtract (1) from (2) term by term to eliminate a₁
48d = - 192 ( divide both sides by 48 )
d = - 4
Substitute d = - 4 into (1) and evaluate for a₁
a₁ + 2(- 4) = 10
a₁ - 8 = 10 ( add 8 to both sides )
a₁ = 18
Answer:
20% off because 10+10=20 and you have to have 100% as the most possible and 100-80=20
and 80% is how much of the original cost u r paying for
Step-by-step explanation:
Cevap:
Salı
Adım adım açıklama:
İlk depozito (Pazartesi) = 8 lira
Günlük yatırılan miktar = 3 lira
74 liraya sahip olmak için gereken gün sayısı;
Gün sayısı = x olsun
8 + 3x = 74
3x = 74 - 8
3x = 66
x = 66 / 3
x = 22 gün
Pazartesiden 22 gün sonra; Salı gününe denk gelecek
The one who start
X= -4 and y=6
Answer:
x ≈ 23.31
Step-by-step explanation:
We can use the law of cosines because we know 2 sides and 1 angle.
The general formula for the law of cosines if the triangle sides are a, b,c and α is the angle between sides a and b. c is the missing side.
In our problem the law of cosines is
x = 
x ≈ 23.31
