Answer:
C
Step-by-step explanation:
The recommended daily intake of a nutrients supplement for a certain age group is 800 mg per day.
Actully supplements needs vary from person to person plus or minus 50 mg.
This means the minimum value is 800 - 50 = 750 mg per day and the maximum value is 800 + 50 = 850 mg per day.
Let x mg be a possible daily amount of nutrients supplement. Then

Subtract 800:

This inequality can be rewritten using absolute value notation as
The formula for the sum of n terms in an arithmetic progression is:
S = n/2 * (2a + (n-1)d)
Here, the common difference, d, is 8 and the first term, a, is 1. Substituting these into the formula, we get:
S = n/2 * (2*1 + 8(n - 1))
S = n + 4n² - 4n
S = 4n² - 3n
The answer is A.
Answer:
Lower Bound = 2.996
Upper bound = 3.244
Step-by-step explanation:
Answer:
Given - a = 4
b = 9
c = 1
To find - Value of equation
Solution -
3b ÷ c^1 - a
Putting the value of a,b and c in the equation
3(9) ÷ (1)^1 - 4
27 ÷ 1 - 4
27 ÷ (-3)
27 × (1 /(-3)
27/(-3)
(-9)
