Damian is watching the temperature of the swimming pool. It is currently 86.6° and cooling 0.5° per minute. After how many minut
es will the swimming pool be 80.8°?
1 answer:
Answer:
12 minutes
Step-by-step explanation:
First we need to look at the change in the two temperatures:
86.6-80.8= 5.8
Next we know that every minute the temperature drops half of a degree so we will find how many minutes until it reaches 80.8:
5.8/0.5= 11.6
Round the answer up to 12 minutes to have a whole number and the pool will be at 80.8 degrees or lower in 12 minutes.

hello : x = (ln(20))/3
Step-by-step explanation:
4 + e3x = 24?
e3x = 24 - 4
e3x = 20
3x = ln(20)
x = (ln(20))/3
Answer:
Im to lazy to calculate the entire answer but its basically the formula is a*b/2
Step-by-step explanation:
Substitute x for -1 in <span> y=3x-1
</span>y = <span><span>(3) <span>(-1) -</span></span><span>1
</span></span>Solve
y = (3) (-1) -1
y = -3 - 1
y = -4
B.) -4 is your answer
