Answer:Rosk Construction has the best work output.
Step-by-step explanation:
1. The unit rate for Rosk Construction is 62
(because a=62w)
2. The unit rate for Fosbert’s Construction is
65 (because 130/2=65; 260/4=65; &
390/6=65. Therefore the unit rate is 65).
3. The unit rate for Durable B Construction is
63 (because 63/1=63; 126/2=63; &
189/3=63. Therefore the unit rate is 63).
p(x)=
- 
+ 800x - 1599
given x = a is a zero of a polynomial p (x) then
(x - a) is a factor of the polynomial
complex zeros occur in conjugate pairs
5 + 4i is a zero hence 5 - 4i is a zero
factors are (x - 3),(x + 13),(x - (5 + 4i) and (x - (5 - 4i)
The polynomial is the product of it's factors
p(x) = (x - 3)(x + 13)(x - (5 + 4i)(x - (5 - 4i)
expanding the factors
p(x) = (
+ 10x - 39)( - 10x + 41)
= - + 800x - 1599
Number 5 is 280 ft because you would just do 20x14
Answer:
Step-by-step explanation:
Use the Law of Cosines to find the measure of angle A from the lengths of the sides.
A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°
B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°
C = 180 - A - B = 95.3°
