Answer:
The first three terms are -30, -27 and -24
Step-by-step explanation:
The formula for nth term of a arithmetic series is given by:
aₙ = a₁ + (n - 1)d
Substitute n = 16 in the given equation:
a₁₆ = a₁ + (16 - 1)d
Where aₙ = a₁₆ = 15. Substitute in the given equation
15 = a₁ + 15d ⇒ Equation (i)
Sum of arithmetic sequence is given by:
Sₙ = n(a₁ + aₙ) / 2
Substitute n = 16 in the above equation:
S₁₆ = 16(a₁ + a₁₆) / 2
Where S₁₆= -120 and a₁₆=15, substitute:
-120 = 16(a₁ + 15)/2
-240 = 16(a₁ +15)
-15 = a₁ + 15
a₁ = -30
Substitute it in Equation (i)
15 = a₁ + 15d
15 = -30 + 15d
15d = 15+30
d = 45/15
d = 3
So
a₁ = -30
a₂ = a₁ + (2-1)d
a₂ = -30 + 3
a₂ = -27
a₃ = a₁ + (3-1)d
a₃ = a₁ + 2d
a₃ = -30 + 2(3)
a₃ = -30 +6
a₃ = -24
Answer:
1320 feet i think
Step-by-step explanation:
41 mph is 60 feet a second
22 x 60 is 1320
i think this is the correct awnser
<u>Given:</u>
It is given that the value of the graph when the input 7 is 
We need to determine the value of x when
<u>Value of x when </u><u>:</u>
The value of x can be determined by using the graph.
From the graph, we need to determine the value of x when other than the value x = 7.
This can be determined by finding the point at which the line meets the point y = 4, we can find the corresponding x - value.
Thus, from the graph, it is obvious that the graph also meets the point y = 4 when x = -8.
Therefore, the input value is x = -8 which makes
Hence, the input value other than 7 for which is x = -8.
Answer:
y = 16
Step-by-step explanation:
The opposite angles of a parallelogram are congruent, hence
10y - 29 = 7y + 19 ( subtract 7y from both sides )
3y - 29 = 19 ( add 29 to both sides )
3y = 48 ( divide both sides by 3 )
y = 16
