Answer:
The number of roots for equation
is 4 .
Step-by-step explanation:
Here, the given function polynomial is :

The Fundamental Theorem of Algebra says that a polynomial of degree n will have exactly n roots (counting multiplicity).
Now here, the degree if the polynomial is 4 (highest power of variable x).
So, according to the Fundamental Theorem, the given polynomial can have AT MOST 4 roots, counting Multiplicity.
Hence, the number of roots for equation
is 4 .
A- 5.3 cm
B- 17.8m
C-9.7 in
D-12 cm
E- 8.3ft
F-25.5m
Answer:
Total wrapping papers Serena and her grandmother = 51/10
Step-by-step explanation:
Serena's wrapping paper for parents:
sq meters
Grandmother's wrapping paper:
sq meters
In order to determine the combined wrapping papers for both Serena and grandmother, all we need is to add both.
i.e.
Total papers = Serena's wrapping paper + Grandmother's wrapping paper





Therefore, total wrapping papers Serena and her grandmother = 51/10
Answer:
76.3 degrees
Step-by-step explanation:
We use inverse cosine to find the angle.
arccos(1.9/8) = 76.26 deg
Answer: 460 Workers
Step-by-step explanation: This is pretty simple, we know there's 198 men...and the ratio is 3:4.
198 ÷ 3 = 66
66 * 4 = 264
There are 264 female workers, and 196 male workers...
264 + 198 = 460
In total, there are 460 workers.
I hope this helps!
