Margo is picking up 600 -ohm resistors for a physics project . (Ohms are the units used to measure circuit resistance.) The package guarantees that the actual resistance is within 10% of the package rating. Which of the following inequalities best models the range of resistances, r?

B

Step-by-step explanation:

Resistance tolerance (like 10%) means that the value is 10% either side of the color coded value.

10% of 600 = 10/100 * 600 = 60

So the highest value can be 600 + 60 or 660

The lowest value is 600 - 60 = 540

The answer is

540 <= r <= 660

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
