X^2 + y^2 = r^2
15^2 + (-8)^2 = [sqrt(17)]^2
r= 17

cos(theta) = x/r = 15/17

Samantha conjectures that for x < -1, it is true that x5 - 2 > x. Is her conjecture correct? Why or why not?
Ronch [10]

Answer:

  The conjecture cannot work for any negative numbers, It works for x > 1.3.

Step-by-step explanation:

An odd power preserves the sign. For |x| > 1, the power increases the magnitude. For x < 0, adding -2 only increases the magnitude more. A negative number of larger magnitude will not be "greater than" the reference. It will be "less than."

It only takes a counterexample to show the conjecture is incorrect.

  x^5 -2 ?? x

  (-2)^5 -2 ?? (-2)

  -32 -2 ?? -2

  -34 < -2 . . . . . . not greater than

ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions
Lady bird [3.3K]

Answer:

C: \lim_{x \to 0} y \to -\infty

Step-by-step explanation:

The y-axis is the asymptote, and G(x) approaches it as x is getting smaller and smaller.

Actually, even more accurate would be to write

\lim_{x \downarrow 0} y \to -\infty

The down arrow shows that x has to approach 0 from the positive side.

3/4 picked apples. If 120 students picked apples, how many picked bananas
Oxana [17]

Answer:

40 students picked bananas

Step-by-step explanation:

3/4 picked apples    

1 - 3/4 = 1/4 picked bananas

3/4x = 120

Multiply both sides of the equation by 4/3

4/3 * (3/4x) = 120/1 * (4/3)

x = 480/3

x = 160

                                               Total of 160 students

                                               /                                   \

                                   120 = apples                  160 - 120 = 40 = bananas

40 students picked bananas

Hope this helps :)
