The rate of change of y with respect to x for this linear function is 1/5 or 0.2
What is a linear function?A linear function is a type of function whose equation is graphically represented by a straight line on the cartesian coordinate. This ultimately implies that, a linear function is typically used for uniquely mapping an input variable to an output variable.
How to calculate the average rate of change?Mathematically, the average rate of change (slope) of a linear function can be calculated by using this formula;
[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
Substituting the given points into the formula, we have;
Average rate of change = (3 - 2)/(10 - 5) = (4 - 3)(15 - 10)
Average rate of change = 1/5 or 0.2

Step-by-step explanation:

We divide 3 by 20:-
3 / 20 = 0 so we divide 30 by 20 and proceed as below:
20)3.00 ( 0.15
20
100

......
The answer is 0.15 which is terminating.
5/11
If we divide as above we get 0.45454545....
The 45 keeps repeating
2/15
Dividing gives 0.133.........
Repeating
7/8 = 0.875
terminating.
9/16
= 0.5625
terminating.
Answer:
3/20 = 0.15 (Terminating)
5/11 = 0.45454 (Repeating)
2/15 = 0.13333 (Repeating)
7/8 = 0.875 (Terminating)
9/16 = 0.5625 (Terminating)
Explanation:
The definition of Terminate means to bring to an end. This would also apply to the decimals. To find whether a fraction is terminating or not, is to simply divide and you will get a decimal, unless it is mixed fraction. Terminating will bring an end, Ex: 1/2 ( 1 ÷ 2 ) which would equal = 0.5 This is an example of a terminating decimal. A repeating decimal is a decimal that never ends of its repetition, Ex: 0.13333333 (Continuous).

Two angles form a linear pair. One angle is 5
more than four times the size of the other angle.
Find the measure of the largest angle.
Answer:
The measure of the largest angle is 145°
Step-by-step explanation:
Since the angles form a linear pair taking two angles that add to 180 and solving for x will give you the answer. the sentence "One angle is 5 more than four times the size of the other angle." your equation should look like this:
5 + 4x. the other angle uses the variable x. So the equation 5 + 4x + x = 180 should result in x = 35. That saying, the smaller angle is 35 and to find the larger angle either plug in x or subtract 180-35. both shoukd result in 145° which is the larger angle.
4. Find the value of x.

find x : 5( x + 4 ) - 3^2 = 2^4
Answer:x=1
Step-by-step explanation:
you would have to distribute the 5 into the (x+4)
then it would be
5x+20-3^2=2^4
then do the exponents
5x+20-9+16
then add 9 by both sides
5x+20=25
then subtract 20 on both sides
5x=5
then divide 5 on both sides
x=1
then check your work by putting 1 for x and you get 2^4=16
Answer:
x = 1Step-by-step explanation:
find x :
5( x + 4 ) - 3^2 = 2^4
5x + 20 - 9 = 16
5x = 16 - 20 + 9
5x = 5
x = 5 : 5
x = 1
----------------
check
5(1 + 4) - 3^2 = 2 ^4
25 - 9 = 16

a soda company had sales of $35,109 million in 2010 and $45,984 million in 2014. use the midpoint formula to estimate the sales in 2012. assume that the sales followed a linear pattern.
The sales in 2012 is estimated to be $40546.5 million if we use the midpoint formula assuming that the sales followed a linear pattern.
Midpoint is a term used in geometry and can be described as the center or middle point of a line segment. It enables you to take two endpoints, and then by using these endpoints you can find the point that is midway between them in the line segment.
Considering,
[tex]P_{1} = (x_{1},y_{1})[/tex]
[tex]P_{2} = (x_{2},y_{2})[/tex]
Here;
[tex]x_{1}[/tex] = 2010
[tex]x_{2}[/tex] = 2014
[tex]y_{1}[/tex] = $35,109 million
[tex]y_{2}[/tex] = $45,984 million
The formula for the midpoint is given as;
[tex]P_{m}[/tex] = {( [tex]x_{1} + x_{2}/2[/tex] ), ( [tex]y_{1} + y_{2} / 2[/tex] )}
[tex]P_{m}[/tex] = {(2010 + 2014 / 2), (35109 million + 45984 million / 2)}
[tex]P_{m}[/tex] = {(4024 / 2), (81,093 million / 2)}
[tex]P_{m}[/tex] = {2012 , 40546.5 million}
Therefore, the sales in 2012 are calculated to be $40546.5 million by using the midpoint formula.

Employee's gross pay is their salary before any payroll deductions such as taxes, benefits, and other expenses are made.
Her goss weekly pay is $409.13.
How to find her gross weekly pay?
Before taxes, benefits, and other payroll deductions are deducted, an employee's gross pay is what they are paid.
Net pay, often known as take-home pay, is the sum that is left over after all deductions have been taken into consideration.
Federal income tax:
306.36+ 43 = 349.36
Medical insurance:
349.36 + 22.35 = 371.71
Credit union:
371.71 + 25 = 396.71
State tax:
396.71 increased by 1.5% is 396.71 * (1.015) = 402.66

A rock climber throws a first aid kit to another climber who is higher up the mountain. The initial velocity of the kit is 12 m/s at an angle of 71 above the horizontal. At the instant when the kit is caught, it is traveling horizontally, so its vertical speed is zero. How far apart are the two climbers (horizontally)?
A rock climber throws a first aid kit to the another climber who is higher up the mountain, the initial velocity of the kit is 12 m/s at an angle of 71 above the horizontal, at the instant when the kit is caught, it is traveling horizontally, so its vertical speed is zero, height difference between climbers is 0.85 m.
What is velocity?Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by specific unit of time (for example, 60 km/h northbound). In kinematics, area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.
Vertical motion of the first aid kit:
The Initial vertical velocity, u = 5.70 sin 45.7 = 4.08 m/s
Acceleration, g = -9.81 m/s²
When climber who is higher up the mountain catches the kit it's vertical speed is zero.
Final vertical velocity, v = 0 m/s
We have the equation of motion, v² = u² + 2as
Substituting
0² = 4.08² + 2 x -9.81 x s
s = 0.85 m
So kit travels 0.85 m vertically.
Height difference between the climbers = 0.85 m.

In mathematics, an operation is a function that transforms 0-n operands or parameters into a known output value. The number of operands affects how complicated the operation is. 90.95 feet per second equates to 62 miles per hour.
What is mathematical operation?An operation in mathematics is the function that converts 0–n parameters or operands into definite output value. The complexity of operation depends on how many operands there are.
The operations that are the most frequently studied are binary operations (i.e., operations of the arity 2), which include addition and multiplication, and the unary operations (i.e., operations of the arity 1), which include additive inverse and the multiplicative inverse. A zero-arity operation, also known as nullary operation, is a constant. An illustration of ternary operation, also known as an operation of arity 3, is the mixed product.
Usually, it is considered that arity is constrained. Even so, the infinitary operations are occasionally considered, in which case "normal" finite dimensionality operations are referred to as finiteary operations.
A partial operation is described as being similar to operation but using a partial function in place of a function.

x = 7.2 , y = 57 , z = 10.8
Step-by-step explanation:
the sum of the 3 angles in the outer triangle = 180° , that is
y + 88 + 35 = 180
y + 123 = 180 ( subtract 123 from both sides )
y = 57
------------
the outer and inner triangles are similar ( AA postulate ) then the ratios of corresponding sides are in proportion, that is
[tex]\frac{x}{12}[/tex] = [tex]\frac{9}{9+6}[/tex] = [tex]\frac{9}{15}[/tex] ( cross- multiply )
15x = 108 ( divide both sides by 15 )
x = 7.2
