Explanation: 68- 18=50
18/4=4.5. It is asking for below 50, and it had to cool for over 4 hours, which is >. I hope this helps. Please give me Brainliest.
Answer:
45 degrees
Step-by-step explanation:
y -
y1 = m (x - x1)
where m is the slope and (x1 , y1) is the point given
m = (y2-y1)\(x2-x1)
we have <span>(-5,-3) and (6,1)
so: m = (1- -3) / (6- -5) = (1+3)/(6+5) = 4/11
and the equation of the line is:
</span>y -
y1 = m (x - x1)
y-1 = 4/11 (x-6)
simplify:
y = 4/11 x - 24/11 +1

I hope that
helps!
Y=2000*

2200=2000*


<span>
so,
y at t=8 is 2000*(</span><span>

)^8
y = 2000(22/20)^2=2000*1.21=</span><span>2420 thats the answer i hope.</span>
