Answer:
-8 + 10 = 2
Addictive inverse of 8 is -8
Answer:
57°
Step-by-step explanation:
The sum of both angles is 90°
3x+5x+2=90
8x+2=90
8x=88
x=11
Plug x into the equation
Larger Angle
5(11)+2=57
Smaller Angle
3(11)=33
I guess the answer is 56 it doesn't make sense
Answer:
Initial 18 degrees Celsius
After 20 minutes, 5 degrees Celsius
Step-by-step explanation:
It’s initial temperature can be calculated as at the time when x = 0
When x = 0, the temperature is -6+24 = 18 degrees Celsius
This is because the exponent part equals 1 since anything raised in to the power of zero is one.
After twenty minutes,
T(x) = -6 +24e^-0.038(20)
T(x) = -6 + 11.224 = 5.224
And that is approximately 5 degrees Celsius to the nearest degree
