Step-by-step explanation:
For women, the initial number is 6, constant rate of change is w, number of years is x.
<u>Find the rate of change and work out the required formula:</u>
- 10w + 6 = 391 ⇒ 10w = 385 ⇒ w = 38.5
<u>Formula:</u>
<u>Similarly for men, we get:</u>
- 10m + 25 = 410 ⇒ 10m = 385 ⇒ m = 38.5
<u>Formula:</u>

2) is correct. (-3) but the arrow will point to the right in the graph
3)Next we’re gonna add 2 on the right side then it becomes b>=0 closed circle arrow will point to the right.
4)multiply 2 by -1. Your answer is o<-2. For the graph open circle on -2 going the left.
5)add 2 to 3 you’re
Answer:
The required specific heat is 196.94 joule per kg per °C
Step-by-step explanation:
Given as :
The heat generated = Q = 85.87 J
Mass of substance (m)= 34.8 gram = 0.0348 kg
Change in temperature = T2 - T1 = 34.29°C - 21.76°C = 12.53°C
Let the specific heat = S
Now we know that
Heat = Mass × specific heat × change in temperature
Or, Q = msΔt
Or, 85.87 = (0.0348 kg ) × S × 12.53°C
Or , 85.87 = 0.4360 × S
Or, S = 
∴ S = 196.94 joule per kg per °C
Hence the required specific heat is 196.94 joule per kg per °C Answer
