Answer:
x = 30°
y = 5
Step-by-step explanation:
The ∆ where you find x is an isosceles ∆ because two of its sides has a length of 40 each, since the other triangle has equal angles of 60° each, it also has equal length sides of 40.
Therefore, x is a base triangle of the isosceles, thus:
x = ½(180 - (180 - 60))
x = ½(180 - 120)
x = ½(60)
x = 30°
Let's find y.
8y = 40 (sides of an equilateral ∆ are equal)
Divide both sides by 8
y = 5
Answer:
337.406388 or 337 people
Step-by-step explanation:
To figure this out, use the compound interest (compounding number?) equation which is Amount = People(1 + rate)^time
So if you fill that out you get
A = 20,000(.96)^100
A = 20,000(0.0168703194)
A = 337.406388
The polynomial is: 
Step-by-step explanation:
We need to write a polynomial f(x) that meets the given conditions: Degree 3 polynomial with zeros 3,-5,4
Since zeros are at 3,-5 and 4
So, x=3, x=-5 and x=4
or:
x-3=0, x+5=0 and x-4=0
Multiplying all factors to find the polynomial:
So, the polynomial is:
