Answer:
a. C(F) = (5/9).F - (160/9)
b. They both readings are equal at C = F = - 40
Explanation:
They are telling us that we are looking for a linear function
If C(F) = a.F + b is the linear function, we use the data to find a and b
C(32) = a.32 + b
0 = a.32 + b
b = - (a.32) (1)
And then
C(212) = a.212 + b
100 = a.212 + b (2)
replacing (1) in (2) we obtain
100 = a.212 + [-(a.32)]
100 = a.212 - a.32
100 = 180.a
a = 100/180
a = 5/9
If a = 5/9 then b = -(a.32)
b = - (5/9).32
b = - (160/9) and the linear function is
C(F) = (5/9).F - (160/9)
For b. they are asking us for a X reading. We must equalize C and F
X = (5/9).X - (160/9)
(4/9).X = - (160/9)
X = -40
C = F at temperature X = - 40
Answer:
D. unsaturated fat
Explanation:
Unsaturated fats are considered the healthiest fats because they improve cholesterol, help reduce inflammation (a risk factor for heart disease), and help decrease the overall risk of developing heart disease. The main source of unsaturated fats are plant-based foods.
Answer:
712.5 kg m/s
Explanation:
Work out the total momentum before the event (before the collision):
p = m × v
Massof Deon = 95kg
Velocity =7.5m/s
Mass of Chuck = 120kg
Velocity = 0m/s
Momentum of Deon before = 95 × 7.5 = 712.5 kg m/s
Momentum of Chuck before = 120 × 0 = 0 kg m/s
Total momentum before = 712.5+ 0 = 712.5 kg m/s
Working out the total momentum after the event (after the collision):
Because momentum is conserved, total momentum afterwards = 712.5 kg m/s
C. It pulls them together
