Answer:
t = 2,3
Step-by-step explanation:
s (t) = t^2 + 2 t + 5
p (t) = 11 + 3 t
A:
s (1) = 8
s (2) = 13
s (3) = 20
s (4) = 29
Now
(b) The values are same at t =2 an t =3.

Answer:
AE = 11.76 units
Step-by-step explanation:
For better understanding of the solution, see the attached figure :
Given : E ∈ AB, m∠ABC = m∠ACE, AB = 34 and AC = 20
To find AE :
In ΔABC and ΔACE,
m∠ABC = m∠ACE ( Given )
∠A = ∠A ( Common angle for both the triangles )
By AA postulate of similarity of triangles, ΔABC ~ ΔACE
So, proportion of the corresponding will be equal.
Hence, AE = 11.76 units
