According to the graph, a person has a fever when his or her body temperature is .

ANSWER:

A number line going from 95 to 102. A closed circle is at 100. Everything to the right is shaded.

Dr. Hilton uses the graph to determine if a patient has a fever. The graph shows body temperatures, in degrees Fahrenheit, that indicate a fever.

According to the graph, a person has a fever when his or her body temperature is  

✔ at least 100 degrees

.

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

4.5%
