*NEED HELP ASAP
Answers
Answer:
The correct option is;
a- 45° only
Step-by-step explanation:
The given equation can be presented as follows;
[tex]\dfrac{cos (2 \cdot x)}{cosine (x) + sin (x)} = 0[/tex]
We have that cos(2·x) = cos²(x) - sin²(x)
Also, we have, by the difference of two squares, the following relation;
cos²(x) - sin²(x) = (cos(x) - sin(x))(cos(x) + sin(x))
Therefore, the given equation can be written as follows;
[tex]\dfrac{cos (2 \cdot x)}{cosine (x) + sin (x)} = \dfrac{(cos(x) - sin(x)) \times (cos(x) + sin(x))}{(cos (x) + sin (x))} =0[/tex]
Crossing the common term, (cos(x) + sin(x)), in the numerator and the denominator, we have;
[tex]\dfrac{(cos(x) - sin(x)) \times (cos(x) + sin(x))}{(cos (x) + sin (x))} = cos(x) - sin(x) = 0[/tex]
From cos(x) - sin(x) = 0, we have;
Adding sin(x) to both sides of the equation
cos(x) - sin(x) + sin(x) = 0 + sin(x)
cos(x) = sin(x)
Therefore, the opposite leg and the adjacent leg of the right triangle formed with reference to the angle x are equal
∴ x = 90/2 = 45° only for 0° ≤ x ≤ 180°

Calculate the slope between the points: (4, 5) and (7, 9)
Answers
Answer:
m=4/3
Step-by-step explanation:
the slope is equal to 4/3
The slope between the points: (4, 5) and (7, 9) is 4/3.
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Points (4, 5) and (7, 9)
so, the slope is
slope = (9-5)/ (7-4)
slope = 4 /3
slope = 1.333
Hence, the slope is 4/3.

Answers
Answer:
will or will not
Step-by-step explanation:
The inequality that represents the number of games [g] Cynthia can bowl to remain within her budget is -
gx ≤ 20
What is the general equation of a Straight line inequality? What is inequality? What are strict and slack inequalities.The general equation of a straight line is -
[y] > [m]x + [c]
[y] < [m]x + [c]
[y] ≥ [m]x + [c]
[y] ≤ [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
Strict inequalities are those inequalities which use either > or < to compare expressions. Example : 2x + 4 > 5
Slack inequalities are those inequalities which use either ≤ or ≥ to compare expressions. Example : 2x + 4 ≥ 5
We have Cynthia’s mom who gave her $20.00 to spend at her friend’s birthday party on Friday night.
Assume that a single game costs $x. Then, the inequality that represents the number of games [g] Cynthia can bowl to remain within her budget is-
gx ≤ 20
Therefore, the inequality that represents the number of games [g] Cynthia can bowl to remain within her budget is -
gx ≤ 20

Which statement is true about function f, which is shown in the graph? f(x) -8x⁵+ 4x³+5x?
A. Function f is neither even nor odd.
B. Function f is even.
C. Function f is odd.
D. function f is both even and odd.
Answers
Answer:
f(-x)=-f(x)
So, Function f is odd
Option C is correct.
Step-by-step explanation:
Which statement is true about function f, which is shown in the graph?
f(x)= -8x⁵+ 4x³+5x?
Function is even if f(-x)= f(x)
and function is odd if f(-x)=-f(x)
Putting x=-x and finding f(-x)
f(-x)=-8(-x)^5+4(-x)^3+5(-x)
f(-x)=-8(-x^5)+4(-x^3)-5x
f(-x)=+8x^5-4x^3-5x
f(-x)=-(-8x^5+4x^3+5x)
f(-x)=-f(x)
So, Function f is odd
Option C is correct.
The function f(x) = -8x⁵+ 4x³+5x is an odd function option (C) Function f is odd is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = -8x⁵+ 4x³+5x
Plug x → -x
f(-x) = -8(-x)⁵+ 4(-x)³+5(-x)
f(-x) = 8x⁵- 4x³-5x
f(-x) = -( -8x⁵+ 4x³+5x)
f(-x) = -f(x) (condition for odd function)
Thus, the function f(x) = -8x⁵+ 4x³+5x is an odd function option (C) Function f is odd is correct.
