The point (-1, 6) is on the lines y = 5x + 3 and y = 2x + 4
How to determine if the points is on the lineFrom the question, we have the following parameters that can be used in our computation:
Point = (-1, 6)
Also, we have
y = 5x + 3
y = 2x + 4
Substitute the known values in the above equation, so, we have the following representation
6 = 5(-1) + 3 = -2 -- false
6 = 2(-1) + 4 = 2 --- false
Hence, the point is not one the line

Which is equal to sin31°?
Answer: 0.515
Step-by-step explanation:
Since our angle is between 0 and 90 degrees, it is located in Quadrant I
In the first quadrant, the values for sin, cos and tan are positive.
Since 31° is less than 90, we can express this in terms of a cofunction
sin(θ) = cos(90 - θ)
sin(31) = cos(90 - 31)
sin(31) = cos(59)
hope this helps!
The value of sin 31° is 0.51504.
Sin 31 degrees is the value of the sine trigonometric function for an angle equal to 31 degrees.
The sin of 31 degrees is 0.51504, but the sin of 31 degrees can also be expressed in radians. To obtain 31 degrees in radian multiply 31° by π/ 180° = 31/180π. Sin 31degrees = sin (31/180 ×π)
The results of sin31° are rounded to five decimal places.
The following are identities of sine 31° :
sin31°
= cos (90°-31°) = cos 59°
= sin (180°-31°) = sin 149°
-sin31°
= cos (90°+31°) = cos 121°
= sin (180°+31°) = sin 211°
Therefore, The value of sin 31° is 0.51504.

what is the angle with tangent 1.125
Answer:
You can find the value of the tangent of any angle on a unit circle. Just draw a vertical line from the x-axis at either zero or pi until it intersects what is the extension of the radius through the angle. The length of that vertical line is the value of the tangent at the angle in question.
Step-by-step explanation:
In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A).

The floor that Ramon lives on, given the address that Ramon gave his friend in Johannesburg, is Floor 18.
Ramon's Flat number, given the address, is Flat 34.
How to write a flat address in South Africa ?In South Africa, there is a way to write the floor that a person stays on and the flat number, in the address that they give to you. The format is such that the first two numbers would represent the floor number. This means that an address of 0208 would means that the floor number is the 2nd floor.
The second two numbers would then be the flat number of the person which means that an address of 0208 would have a flat number of 08.
Ramon's address of 1834 Norman Heights Hillbrow Johannesburg would then be Floor 18 and Flat 34.

If 30 more HRDS responded to the survey,
which of the following is the best estimate of
the number of people employed by the 30
organisations these HRDS represent?
Answer:
Step-by-step explanation:
Assuming that the same ratio of invitees to respondents holds true for the 30 additional HRDs, the best estimate of the number of people employed by the 30 organisations is 67.5 (30/45*100). This means that the total number of people employed by the 363 organisations represented by the 333 invited HRDs and the 30 additional HRDs is 5,475 (5,407.5 + 67.5).

brilliancy ratio y. Describe the reasonable domain and range values. Graph the function.
The domain and range are (0 , ∞) and (0 , ∞).
What is domain ?
The collection of all potential inputs for a function is its domain. For instance, the domain of f(x)=x2 and g(x)=1/x are all real integers with the exception of x=0.
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
The set of all initial elements in ordered pairs constitutes the domain (x-coordinates). The set of all second items in ordered pairs is the range (y-coordinates).
Given
y = 80 / x

What is system of linear equationA system of linear equations is a set of two or more linear equations that contain two or more variables. The goal of solving a system of linear equations is to find the values of the variables that satisfy all of the equations in the system simultaneously.

A 1.5 kg pendulum swings from point A of height yA = 0.04m to point B of height yB = 0.12m. The heights are relative to the lowest height. What is the change in gravitational potential energy from A to B?
Answer:
The change in gravitational potential energy from point A to point B can be calculated using the formula:
ΔU = mgh
Where:
m = mass of the pendulum = 1.5 kg
g = acceleration due to gravity = 9.8 m/s^2
h = change in height = yB - yA = 0.12 m - 0.04 m = 0.08 m
So, the change in gravitational potential energy from A to B is:
ΔU = (1.5 kg)(9.8 m/s^2)(0.08 m) = 1.176 J
So, the change in gravitational potential energy from A to B is 1.176 Joules.

Which expression is equivalent to 3 square root 27c7 • 3 square root 250c2, if c≠0
Answer:3 square root 27c7 • 3 square root 250c2 can be simplified by applying the property of square roots, (√a * √b) = √(ab) .
So, 3 square root 27c7 • 3 square root 250c2 = √(27c7 * 250c2) = √(27250c7c2) = √(675c7*c2) = √(675c9) = √(675) * √(c9) = 15c3
Therefore, 3 square root 27c7 • 3 square root 250c2 = 15c3 is the equivalent expression.

Chau used 6 rolls of blue fabric to make costumes for the annual school play. He used the total length of 14.4yd of fabric. If each roll had the same length of fabric, how much fabric was in each roll? Write your answer in inches.
Answer: Each roll of fabric had 86.4 inches of fabric.
Step-by-step explanation:
Each roll of fabric used in the annual school play had a length of 14.4yd / 6 rolls = 2.4 yards of fabric.
1 yard = 36 inches
so, 2.4 yards = 2.4 x 36 inches = 86.4 inches
Each roll of fabric had 86.4 inches of fabric.
Explanation: The problem states that Chau used 6 rolls of blue fabric, and the total length of fabric used was 14.4 yards. Dividing the total length of fabric by the number of rolls gives the length of each roll, which is 2.4 yards or 86.4 inches.
