Sec x =  1/Cosx

Pi radians = 180 degress

Pi/12 = 180/12 = 15 degrees.

Sec15° = 1/Cos15°

Sec pi/12 = Sec 15° = 1/Cos 15°

Cos 15° = 0.9659  using a calculator.

Sec pi/12 = Sec 15° = 1/Cos 15° = 1/0.9659 = 1.0353

Sec Pi/12 = 1.0353

makkiz [27]
X = B.......x - 17 = A

x + x - 17 = 87
2x - 17 = 87
2x = 87 + 17
2x = 104
x = 104/2
x = 52........so state B has 52 electoral votes

x - 17 = A
52 - 17 = A
35 = A.....so state A has 35 electoral votes

The graph of function f is shown above. if g(x)=x^2/f(x) what is the value of g'(1)?​
Alla [95]

Answer:

Step-by-step explanation:

Find the equation of the segment going from (0,-5) to (3,7)

y intercept = -5

Slope = (-5 - 7) / (0 - 3) = -12/-3 = 4

equation: y = 4x - 5

g(x) = x^2 / f(x)

f(x)=  (4x - 5)

g(x) = x^2 / (4x - 5)

g'(x) = x^2 * (4x - 5)^-1

g'(x) = 2x*(4x - 5)^-1  + (-1) *4* x^2 (4x - 5)^-2

I will leave that monster the way it is and just find g'(1)

g'(1) = 2(1) * (4(1) - 5)^-1    +    (-1) (1)^2 *4* (4(1) - 5)^-2

g'(1) = 2(1) * (-1)^-1             +    (-1) (1)^2 *4 * (-1)^2

g'(1) = -2                      +        (-1) (1)^2 (4)

g'(1) = - 2                     +        (-1) (1)^2 (4)

g'(1) =  - 2 - 4

g'(1) = - 6

What is the end behavior of the function f(x)= -3x^7+4x^5-14?
adoni [48]

Answer:

  • f(-∞) → ∞
  • f(∞) → -∞

Step-by-step explanation:

The degree of the function is odd, so the ends tend in opposite directions. The leading coefficient is negative, so the right end (as x gets large) will tend toward -∞. Then the left end tends toward +∞.

_____

If the degree is even, both ends tend in the same direction. That direction matches the sign of the leading coefficient.
