Answer:
11
Step-by-step explanation:
ANSWER
4 roots.
EXPLANATION
The given polynomial function is

This is a fourth degree polynomial.
According to the Fundamental Theorem of Algebra, an nth degree polynomial has n roots.
This roots include both real and complex roots.
Also repeated roots or roots with multiplicity greater than one are counted as distinct.
Since the given polynomial function is a fourth degree polynomial, the Fundamental Theorem of Algebra, says that this polynomial has 4 roots.
Answer:
a) s = -16
+ 192t + 96
b) Height of the football after 2 seconds is 448 feet.
ii. The football would not hit the ground after 2 seconds.
Step-by-step explanation:
Given:
s = -16
+
t + 
where: s is the height of the football above the ground, t is the time,
is the initial velocity and
is the initial height.
The height of the building =
= 192 feet and the initial speed of the ball =
= 96 feet per second, then;
s = -16
+ 192t + 96
a) The polynomial is given as:
s = -16
+ 192t + 96
b) The height of the football when t = 2 seconds is;
s = -16(2) + 192(2) + 96
= -32 + 384 + 96
= -32 + 480
s = 448
The height of the football when t = 2 seconds is 448 feet.
ii. The football would not hit the ground after 2 seconds.
Answer:
11x+5.25
Step-by-step explanation:
Open the brackets
1/2 x 10x= 5x, 1/2 x 6 =3
3/4 x 8x=6x, 3/4 x 3 =2.25
Like terms together
5x + 6x + 3 + 2.25
Answer
11x + 5.25
Answer:
4.33
Step-by-step explanation:
If you don't have the cube root function in your calculator, u can chose a choice instead and cube the value.
9x9 is already 81, hence 9x9x9 > 81
27 x 27 Is definitely more than 81
Hence the only reasonable answer is 4.33
