Answer:
-17.5 degrees Celsius in 5 hours
Step-by-step explanation:
0(current temp)-3.5x(temp decrease)=5(hours)
then simplify
So youd need to factor the quadratic first.
now set each factor equal to zero and solve for X.
x+6=0
x=-6
x-1=0
x=1
so the roots of the quadratic are x=-6 and 1
First you would find a common denominator. If 40 is the LCM then you would have to add playing games, instruction,warm-up, and cool-down. Then you will subtract the sum from the total class time and bam! You get your answer!

Here is what I got hope it helps!!!!!!!
Step-by-step explanation:
We would be talking about velocity.
Scalar refers to a speed, but not a given direction.
For me, the easiest way to distinguish a scalar from velocity is to think about the mechanism of scales. A scale can go up and down, left and right, but it doesn't give a specific direction. In a Cartesian plane, the scale of (-4, 0) has the same scale as (4, 0) from the origin at (0, 0) because scale doesn't define a specific directional change in the same way magnitude doesn't have a specific direction.
Velocity, on the other hand, requires a direction because it is defined as the rate of change of an object from its initial position to its final position. In this instance, a direction is required as we need to define an object's acceleration or deceleration.
