Answer:
61°C
Step-by-step explanation:
Newton's Law of cooling gives the temperature -time relationship has:
T (t) = 20 + 75 е⁻(t/50)-------------------------------------------------------- (1)
where Time is in minutes (min) & Temperature in degree Celsius (°C)
During the first half hour, t = 30 mins
Substituting into (1)
T = 20 + 75 е⁻(30/50)
= 20 + 75(0.5488)
= 20 + 41.16
= 61.16°C
≈ 61°C
Answer:
y=9x+75
Step-by-step explanation:
since we know that the slope must be the same for two lines to be proportional, we are gonna start there.
so our equation is: y= 9x + b
we need to find b to complete our equation, so substitute in the points we were given.
3 = 9(-8) + b
so now,
3 = -72 + b
now we have to isolate b to find out what it is,
3 = -72 + b
+72 +72
so now: 75= b
Put that back into the starting equation: y = 9x + 75
Answer:
-See below
Step-by.step explanation:
In the first column, on the left of the vertical line, you place the first digit of the number , then on the second row on you place the second digit.
So on the second row you have the entries:
1 | 2 2 4 representing 12, 12 and 14.
On the first row the 2 0ne digit numbers 3 and 8 are represented by
0 | 3 8.
Similarly the last 2 rows are:
2 | 0 1 3 6
3 | 4
The first one is B hope this helps
I think it'd be 1/16 of the band because you'd multipy 1/4 by 1/4
