Answer:
h (1) = $140
Step-by-step explanation:
10x + 150
-10 -10
150-10
=140
so the answer must be $140
The temperature of the ice cream 2 hours after it was placed in the freezer is 37.40 °C
From Newton's law of cooling, we have that
Where
From the question,
∴
Therefore, the equation becomes
Also, from the question
After 1 hour, the temperature of the ice-cream base has decreased to 58°C.
That is,
At time ,
Then, we can write that
Then, we get
Now, solve for
First collect like terms
Then,
Now, take the natural log of both sides
This is the value of the constant
Now, for the temperature of the ice cream 2 hours after it was placed in the freezer, that is, at
From
Then
Hence, the temperature of the ice cream 2 hours after it was placed in the freezer is 37.40 °C

Answer:
134 degrees.
Step-by-step explanation:
This is a simple one.
The arc RS subtends an angle of 67 degrees on the circumference,
So the measure of the arc RS is 2 * 67 = 134 degrees.
Answer:
the would be m=4
Step-by-step explanation:
From the equation given, the time for the black mamba snake to cover distance d, will be d/16 while that for the the rought-scaled snake would be d/1.5.
Assume that the distance covered by both snakes is 200 meters;
Then,
Time taken by the black mamba is 200/16 = 12.5 seconds, and
Time taken by the rought-scaled snake is 200/1.5 = 133.33 seconds
Clearly the black mamba is faster at 12.5 seconds compared with the rought-scaled snake.
