Answer:
it is a polynomial and the degree is 6
Step-by-step explanation:
a polynomial is a function which involves positive integral powers
That is if the exponents are positive integers
2 * plane speed in still air = 289mph + 257mph = 546
plane speed in still air = 273 mph
plane speed in still air + wind speed = 289
273 + wind speed = 289
Therefore, wind speed = 16 mph
Answer:
(4,1)
Step-by-step explanation:
The rule for reflecting over the X axis is to switch the value of the y-coordinate of each point, but leave the x-value the same
Answer:
Option A
Step-by-step explanation:
To find all missing sides of a right triangle we use the sine, cosine or tangent ratio as below,
sinθ = 
cosθ = 
tanθ = 
Now we take an angle measuring 60°
sin(60°) = 
y = 4√3
tan(60°) = 
√3 =
x = 2√3
Therefore, Option A will be the correct option.
Answer:
(f-g)(x)=-x^(2)+2x+8
the solutions are:
<em><u>x=4 or x=-2</u></em>
Step-by-step explanation:
(f-g)(x)=2x+1-(x^(2)-7)
(f-g)(x)=-x^(2)+2x+1+7
(f-g)(x)=-x^(2)+2x+8
does this help or should I solve for the zeros/solutions of this quadratic equation?
then:
-x^(2)+2x+8=0
-(x^(2)-2x-8)=0
x^(2)-2x-8=0
(x-4)(x+2)=0
<em><u>x=4 or x=-2</u></em>
