Answer:
Domain: {-6, -1, 7}
Range: {-9, 0, 9}
The relation is not a function.
Step-by-step explanation:
Given the relation: t{(−1,0),(7,0),(−1,9),(−6,−9)}
In the ordered pairs:
- The domain is the set of all "x" values
- The range is set of all "y" values
- We do not need to list any repeated value in the range/domain more than once.
Domain: {-6, -1, 7}
Range: {-9, 0, 9}
Next, we determine whether the relation is a function.
For a relation to be a function, each x must correspond with only one y value.
However, as is observed in the mapping attached below:
The x-value (-1) corresponds to two y-values (0 and 9)
Therefore, the relation is not a function.
Answer:
The height of each step is 1957 yard
Step-by-step explanation:
we are given
Tristan is building steps up to a deck that is 15656 yards above the ground
so, total height =15656 yards
Number of steps =8
now, we can use formula
Height of each step = ( total height)/( number of steps)
now, we can plug these values
and we get
Height of each step is
Answer:
n<1.3
Step-by-step explanation:
-2.5n+8.7>5.45
add -8.7 on both sides
-2.5n>-3.25
divide both sides by -2.5
n<1.3 (after division inequality sign changes)
answer of Q2 is -4 2/3
answer of Q3 is -2/9
answer of Q4 is -23/3
answer of Q5 is 2^2. 3^2.5
A) 144/4 = 36 metres per side
b) 18*3 = 54
54+54+18+18= 144 metres
dimensions would be 54 by 18
The unit price will be 6.50
