Answer:
m<DEF = 8y - 6
Step-by-step explanation:
Given that: DEG = , and FEG =
.
The given triangle is an isosceles triangle with sides DE ≅ DF.
But,
m<DEF = DEG + FEG
= +
= 3y + 4 + 5y - 10
= 8y - 6
m<DEF = 8y - 6
Therefore, the measure of < DEF is 8y - 6.
Answer:
with
Step-by-step explanation:
We can study what happens day by day starting with day one (1) to understand how the recursive relation can be constructed:
Day # Number of stamps What is added relative to previous day
1 d1 = 80 + 1 = 81
2 d2 = 81 + 2 = 83 d2 = d1 + 2
3 d3 = 83 + 4 = 87 d3 = d2 +
4 d4 = 87 + 8 = 95 d4 = d3 +
5 d5 = 95 + 16 = 111 d5 = d4 +
6 d6 = 111 + 32 = 143 d6 = d5 +
(n+1) d(n+1) = dn +
