Write it out like so..
Small
A = lw
Large
A = (2l)(2w)
A = 4(lw)
Ratio is 4:1
The graph is a function. When drawing a vertical line, there will be two circumstances:
- The line intersects only one point on a graph.
- The line intersects more than one point on a graph ( POI > 1 )
For the first circumstance, the graph that has only one intersect with a line - it is a function. For the second circumstance, the graph cannot be a function as it gives more than one y-value for a single x-value.
The conclusion is that if a line only has one intersect on a graph then it is a function. Otherwise, not a function but a relation instead. All functions are relations, but not all relations can be functions.
Answer
- The graph passes the vertical line test and is a function.
Answer:
13.27 cm
Step-by-step explanation:
The hypotenuse is always the longest side so:
a^2 + 20^2 = 24^2
a^2 + 400 = 576
a^2 = 176
a = 13.27
The 4-member family can be seated in 4! ways.
The two brothers can be seated together in 2! ways.
Therefore, the total number of ways is

Diagrammatically, the result is shown in the figure below. The two brothers are family members 3 and 4, shown in shaded color.
Answer: 12 ways.
We will use the distributive property. -4 times 9z=-36z -4 times -2=8 so we have -36z+8 as our answer
