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

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
