I'm guessing we have
S1 = 1000
S2 = 1000 + 500
S3 = 1000 + 500 + 250
S4 = 1000 + 500 + 250 + 125
S5 = 1000 + 500 + 250 + 125 + 62.5
Just adding that up, S5 is
Answer: 1937.5
Do they want you to use the geometric series formula? We'll check it that way.
We have first term a=1000 and common ratio r=1/2. In general
For us that's
S5 = (1000 (1 - (1/2)^5))/(1 - 1/2) = 2000(1 - 1/32)
= 2000(31)/32 = 62000/32 = 1937.5 √
Math works!
The circumference of a circle is 2(3.14)r, and if 8.5 * 2 is 17, the answer will be 17*3.14.
An estimate is 51, and the actual answer is 53.38.
Answer:
-6
Step-by-step explanation:
Plug in x = 3 in the equation: 3(3 - 4) + 2(3) - (3)^2
Now simplify with order of operations:
3(3 - 4) = -3
2(3) = 6
-(3)^2 = -9
-3 + 6 - 9 = -6
First you must derive the equation to find the slope:
y = 3x ^ 2 - 3
y '= 6x
Then, for x = 1 we have the slope is:
y '(1) = 6 (1) = 6
Then the equation of the line with slope equal to 6 and passing through point (0, -3) is:
y = 6x - 3
The slope is m = 6
