Answer : The specific heat of the metal is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of metal = ?
= specific heat of ice =
= mass of metal = 1.00 kg
= mass of ice = 1.00 kg
= final temperature of mixture =
= initial temperature of metal =
= initial temperature of ice =
Now put all the given values in the above formula, we get:
Therefore, the specific heat of the metal is,
Answer:
Step-by-step explanation:
Be VERY careful. When it write out the equation that way, it will give the speculation of this:
Now, in this case, since you were extra explanatory about this [what is written in parentheses], two factors I know of that multiply to 15 are these:

Answer:
Real values of x where x < -1
Step-by-step explanation:
Above the x-axis, the function is positive.
The function is decreasing when the gradient is negative.
The function has a positive
coefficient, therefore the vertex is a local minimum;
This means the gradients are negative before the vertex and positive after it;
To meet the conditions therefore, the function must be before the vertex and above the x-axis;
This will be anywhere before the x-intercept at x = -1;
Hence it is when x < -1.
