Given the functions j(x) = x2 + 3 and k(x) = x2 − x + 4, which operation results in a 2nd degree polynomial?
GrogVix [38]
Addition is the correct answer.

x^2 is the part where you get the second degree term. If you add x^2+x^2 you get 2x^2. If you subtract x^2-x^2 you get 0. If you multiply x^2*x^2 you get x^4, which is a fourth degree term

Tangent line of f(x) = sec x @ (pi/3, 2)
Dmitry_Shevchenko [17]
The derivitive of sec(x) is sec(x)tan(x)

find the slope at pi/3

sec(pi/3)=2
tan(pi/3)=√3

sec(x)tan(x) at x=pi/3 is 2√3

for slope=m and a point is (x1,y1)
the equation is
y-y1=m(x-x1)
slope=2√3
point=(pi/3,2)

equation is
y-2=2√3(x-pi/3)

List of reading his cell phone and monthly service please try and sell offers a new phone for $50 in unlimited service for a mon
Shtirlitz [24]

Answer:

After 5 months the cost of the two phones and monthly service be the same.

Step-by-step explanation:

1st service cost = $50 + $40x, where "x" represents the number of months

2nd service cost = $50x

Now we have to find the number of months the cost of the two phones and monthly service be the same.

Now we have to equivate and find the value of x.

50x = 50 + 40x

Subtracting 40x from both sides, we get

50x - 40x = 50 + 40x - 40x

10x = 50

Dividing both sides by 10, we get

x = 50/10

x = 5

After 5 months the cost of the two phones and monthly service be the same.

Hope you will understand the concept.

Thank you.

Subtracting v - q, will be subtracting the atmosphere to the sun - surface to the sun.

The answer will be negative distance of the atmosphere.

However, we cant really have a 'negative' atmosphere, this is where the |absolute value| signs make this problem correct.
