Tn=n²+3
from 4 to 7....the difference is 3, then from 7 to 12 the difference is 5 and from 12 to 19 the difference is 7
therefore we constantly add 2 to the difference

Step-by-step explanation:
Top second one under grass and across from minor 77.972.
Answer:
a. 0.588
b. 0.0722
c. 4.576 sqft/sec
Step-by-step explanation:
Let b and h denote the base and height as indicated in the diagram. By pythagoras theorem,
because it is a right angle triangle.
It is given that 
Now differentiate (1) with respect to t (time) :


The minus sign indicates that the value of h is actually decreasing. The required answer is 0.588.
b. From the diagram, infer that
. When b = 8, then
.
Differentiate the above equation w.r.t t

c. The area of the triangle is given by
. Differentiating w.r.t t,

Plugging in b = 8, h = 13.856,
,
Answer:
6(x-1)
Step-by-step explanation:
Open brackets.
4x-8+2x+2
Solve and simplify
6x-6
You can take 6 common
