Answer:
5x^4−160x^2+4/2x^2
Step-by-step explanation:
5x/2 x−16+2/x^2−64
5/2x^4−80x^2+2/x^2
5x^4−160x^2+4/2xx
5x^4−160x^2+4/2x^2
Answer:
x^3 - x^2 - 6x
Step-by-step explanation:
First, add f +g
x^2 + 1 + 5 -x (combine like terms)
x^2 - x +6
Next, multiply the new equation by x
x(x^2 - x + 6) Use distributive property
= x^3 - x^2 + 6x
Answer:
d = 167.7 m
Step-by-step explanation:
We have,
Mrs. Tyner drove about 150 km east from Pearland, to Houston, Texas. She drove about another 75 km north to Dallas.
It is required to find the approximate air distance from Pearland to Dallas, Texas.
The resultant vector will give the approximate air distance. So,
So, the approximate air distance from Pearland to Dallas, Texas is 167.7 m.
Answer:
Part A:
x+y= 95
x = y+25
Part B : 35 minutes
Part C : No
Step-by-step explanation:
Eric plays basketball and volleyball for a total of 95 minutes every day
x+y= 95
Where:
x =the number of minutes Eric plays basketball
y= the number of minutes he plays volleyball
He plays basketball for 25 minutes longer than he plays volleyball.
x = y+25
System:
x+y= 95
x = y+25
Replacing x=y+25 on the first equation:
(y+25) + y =95
Solving for Y
y+25+y =95
25+2y=95
2y=95-25
2y=70
y = 70/2
y = 35 minutes
Part C : No
if x = 35
x+y= 95
35+y =95
y= 95-35
y = 60 minutes
Replacing y=60 on the other equation:
x = y+25
35 = 60+25
35 ≠85
Cos(pi) = -1
You should have this memorized along with other values such as
sin(0) = 0
cos(0) = 1
sin(pi/2) = 1
cos(pi/2) = 0
sin(pi) = 0
cos(pi) = -1
sin(3pi/2) = -1
cos(3pi/2) = 0
and remember that tan = sin/cos
