Answer:
Step-by-step explanation:
The answer is actually
Let:
S=1+2+3+4+5+6+7+8+9+n
We know the answer to the following infinite sum:
S2=1-1+1-1+1-1+1-1+1-1+1-1+1-....= - 1/2
We can therefore solve for this sum:
S3=1-2+3-4+5-6+7-8+9-....
We add them:
S3= 1-2+3-4+5-6+7-8...
S3= +1-2+3-4+5-6+7-8...
________________
2S3= 1-1+1-1+1-1+1-1+1-....
Therefore:
2S3=S2=
Answer:
About 316,955 people
Step-by-step explanation:
The population of this city can be modeled with the formula , where P represents the current population, I represents the initial population, and t represents the amount of time in years since the start of the model. Plugging in 145,201 for I and (2037-2021)=16 for t, we get:
(6, 7) and (-3, -2)
1. Find the slope.
m = slope
m = (-2 -7)/(-3 -6)
m = -9/-9
m = 1
2. Plug the slope and one of the points into the equation y - y_1 = m(x - x_1).
y - 7 = 1(x - 6)
3. Solve for y.
y - 7 = x - 6
y = x - 6 + 7
y = x + 1
Answer is choice D.
If the pattern goes 26, 57, 88 you can find the difference between each number to see how much it's going up by each time. 57 - 26 = 31 and 88 - 57 = 31
That means each week the number of boxes of a new cereal increases by 31, or +31
