Answer:
A) A function is a rule that assigns one input into one output.
The general function is f(x) = y
Where we have one input, x, and one output, y.
But this is a really simple type of function, for example, you could define a function that calculates the volume of a box of length L, width W, and height H as:
V = f(L, W, H) = L*W*H
Then we have "3 inputs" and one output, right?
Well, not exactly, here the set (L, W, H) is called the input, so here we have a single input consisting of 3 variables.
Also we can have functions with a single input into vector-like outputs
For example:
(y, z) = f(x)
So for the input x, we got two values in the output y and z, but this is a single output defined as (y, z), then we always have a single output.
B) The graph of a function is a set of points consisting of one input and the corresponding output.
C) You can determine if a graph represents a function by using the vertical line proof.
A rule that assigns inputs into outputs is only a function if each input is assigned into only one output.
Then if we draw a vertical line that intersects our graph, it should intersect it only one time for functions.
If the line intersects the line two times this means that a single input has more than one output, then this is not a function.
Answer:
A: exactly one, each
B: ordered pairs
C: vertical line test

Two ovens have measurements as shown. Which oven has a greater volume? How much greater is
its volume?
The question is incomplete:
Two ovens have measurements as shown. Which oven has a greater volume? How much greater is its volume?
The image with the information is below.
Answer:
-Oven B has a greater volume.
-Its volume is greater by 768 in³.
Step-by-step explanation:
First, you have to calculate the volume of each oven by multiplying the area of the base by the height:
Oven A: 576 in²*15 in= 8640 in³
Oven B: 672 in²*14 in= 9408 in³
Now, you have to calculate the difference between the volumes:
9408-8640=768
According to this, the answer is that oven B has a greater volume. Its volume is greater by 768 in³.
Select all the equations that are true when xis -4.
A)-8 = 2x
B) -12 = x.-3
C) -12 = x+x+x

Mogaka and Ondiso working together can do a piece of job in 6 days. Mogaka
working alone takes 5 days longer than Ondiso. How many days does it take
Onduso to do the work alone?
(3mks)
Answer:
10 days
Step-by-step explanation:
Mogaka and Ondiso working together can do a piece of job in 6 days. Mogaka working alone takes 5 days longer than Ondiso. How many days does it take Ondiso to do the work alone?
Let us represent :
The number of days
Mogaka worked alone = x
Ondiso worked alone = y
Total days worked together = T
Mogaka and Ondiso working together can do a piece of job in 6 days.
Hence,
1/x + 1/y = 1/T
Mogaka working alone takes 5 days longer than Ondiso.
x = y + 5
Therefore:
1/y + 5 + 1/y = 1/6
Multiply all through by (y+5)(y)
= y + y + 5 = (y+5)(y)/6
= 2y + 5/1 = (y+5)(y)/6
Cross Multiply
6( 2y + 5) = (y+5)(y)
12y + 30 = y² + 5y
= y² + 5y - 12y - 30 = 0
= y² - 7y - 30 = 0
Factorise
= y² +3y - 10y - 30 = 0
y(y + 3) - 10(y + 3) = 0
(y + 3)(y -10)= 0
y + 3 = 0, y = -3
y - 10 = 0
y = 10 days
Note that
The number of days Ondiso worked alone = y
Hence, it takes 10 days for Ondiso to work alone

How many 1 -by-1 -by-1 -inch cubes fit inside of this
rectangular prism?
The number of 1 -by-1 -by-1 -inch cubes that can fit inside of this rectangular prism 120 cubes.
Volume of a rectangular prism
volume = lwh
where
l = lengthw = widthh = heightTherefore,
volume = 10 × 3 × 4 = 120 inches³
Volume of the cube = l³
where
l = side lengthTherefore,
volume = 1 × 1 × 1 = 1 inches³
Therefore, the number of 1 -by-1 -by-1 -inch cubes that can fit inside of this rectangular prism is as follows;
number of cube = 120 / 1 = 120 cubes

Find the slope of the line perpendicular to AB. A(3, 5) and B(3, -8).
Answer:
m = 0
Step-by-step explanation:
AB has a slope of y2 - y1 / x2 - x1 so -8-5/3-3 so -13/0 = undefined so it is a vertical line, so any line that is horizontal will be perpendicular to it, so horizontal lines have a zero slope
