QveST [7]

Answer:

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

$750\le x\le 850$

Subtract 800:

$750-800\le x-800\le 850-800\\ \\-50\le x-800\le 50$

This inequality can be rewritten using absolute value notation as

$|x-800|\le 50$

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.

Evaluate the expression if a = 4, b = 9, and c = 1.

uranmaximum [27]

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)
