The value of csc x=-13/5.
Given that the sin x=-5/13 and x∈[3π/2 , 2π).
A trigonometric function is a real function that relates the angle of a right triangle to the ratio of the lengths of the two sides. The basic functions are sin, cos, tan, cot, sec, csc.
The given function is sin x=-5/13.
As we all know that sin x=1/csc x or csc x=1/sin x.
As it is given that x∈[3π/2 , 2π) that means x lies in fourth quadrant and in fourth quadrant sin and csc is negative in it.
So, we will apply this identity csc x=1/sin x, we get
csc x=1/(-5/13)
csc x=-13/5
And it also lies in x∈[3π/2 , 2π).
Hence, the value of csc x when sin x=-5/13 and x∈[3π/2 , 2π) is csc x=-13/5.

Answer:
7: #3. 8: #2
Step-by-step explanation:
in the first question the format is simply (x, y) and because it is a translation, we are basically just moving the point by these numbers, with this information, it is simply moving x to the left(negative) 8 times, and y(up/positive) 4 times. The next question is simply moving the point across the x axis by the same amount that it is above the x axis, so it would be one down from the x-axis' bold line, or in this case moved 2 y-units down. Hope this helps mate :)

Answer:
a. A = 647
P = 120
b. A = 192
P = 70
Step-by-step explanation:
a. A = (16 x 12) + (13 x 35) = 192 + 455 = 647
P = 16 + 12 + 19 + 13 + 35 + 25 = 120
b. A = (12 x 8) + (8 x 12) = 96 + 96 = 192
P = 12 + 8 + 7 + 8 + 12 + 8 + 7 + 8 = 70

Linear equation : an equation in which there is only one variable present. It is of the form Ax + B = 0, where A and B are any two real numbers and x is an unknown variable that has only one solution.
Since there is a linear relation between the two, we can assume the equation can be written as:
y = mx + c
From the given data, we get
0.24 = m(0) + c
c = 0.25
Using the second point:
1 = m(1) + 0.25
m = 1 − 0.25 = 0.75
Hence, the equation is y = 0.75x + 0.25.
If x = 4, then:
y = 0.75 × 4 + 0.25
y = 5.50
Hence, He have to pay $3.25.

three zebras are chilling in the desert. suddenly a lion attacks. each zebra is sitting on a corner of an equally length triangle. each zebra randomly picks a direction and only runs along the outline of the triangle to either edge of the triangle. what is the probability that none of the zebras collide?
Probability that no zebras collide is 0.25
The zebras are represented as z1, z2 and z3.
Z1 to B, Z2 to C, and Z3 to A come first [tex]= (\frac{1}{2})^3[/tex]
Following that, z1 to C, z2 to A, and z3 to B = [tex](\frac{1}{2})^3[/tex]

Property to find the sum or product identify the property you used 6 x 43
The multiplication of 6 × 43 by applying the distributive property of multiplication will be 258.
What is multiplication?The general mathematical operation of multiplying two or more numbers to get a new multiplied number.
If both values are more than or less than one, the resultant multiplication will be greater or smaller than the numbers that will be multiplied.
For reference 4 × 3 = 12 and 4 × 0.5 = 2.
Given the multiplication,
6 × 43

The value of x that makes the lines m and n to be parallel lines is 45 degrees
How to determine the value of x that makes the line parallel?The figure that completes the question is added as an attachment
From the figure, we have the following angles
Angle = x and 3x
The angles are interior of parallel lines
This means that they add up to 180 degrees
So, we have the following equation
Angle 1 + Angle 2 = 180 degrees
Substitute the known values in the above equation
So, we have
x + 3x = 180
Evaluate the like terms in the above equation
So, we have:
4x = 180
Divide both sides of the above equation by 4
So, we have
x = 45
Hence, the value of x that makes the lines m and n to be parallel lines is 45 degrees

solve the following simultaneous equations
y=x^2
y= x+6
The solution of the simultaneous equations are x = 2, 3 and y = 3,9.
What are simultaneous equation?In mathematics; a set of simultaneous equations, also known as a system of equations or an equation system, it is a finite set of equations for which common solutions are sought.
WE have given simultaneous equations as;
y = x^2 ...(i)
y = x + 6 .....(ii)
Now Equating (i) and (ii) we get,
x^2 = x + 6
or, x^2 - x - 6 = 0
Then Solving we get;
x^2 - 3x - 2x - 6 = 0
x(x - 3) -2(x - 3) = 0
(x - 2)(x - 3) = 0
So, x = 2, 3
Now Putting x = 2, 3 in equation (i) we get;
y = 2^2
y = 4
and,
y = 3^2
y = 9
Thus, y = 3,9
Hence the solution of the simultaneous equations are x = 2, 3 and y = 3,9.
