aculalli i dont now the answer i only want a point ):
Answer:
2) Yes, each x-coordinate is only used once.
3) {1,2,3,4}
4) {25,45,60,70}
5) (3,60)
6) No because (4,7) and (4,25) share the same x-coordinate.
Step-by-step explanation:
A relation is a function if there is no more than one y-value assigned to an x.
Any x used can only be used once in an order pair.
You that here.
(1,25)
(2,45)
(3,60)
(4,70)
So basically because all of the x-coordinates are different, this is a function.
The domain is the x-coordinate of each pair (the first of each pair):
{1,2,3,4}.
The range is the y-coordinate of each pair (the second number of each pair):
{25,45,60,70}.
One ordered pair that I see in the table is (3,60). There are 3 others you can choose and I named them above.
{(4,10),(3,15),(1,5),(2,25),(4,25)} is not a function because there are more than one pairs with the same x-coordinate,4.
Answer:
16% increase
Step-by-step explanation:
A percentage change can be calculated from ...
percentage change = ((new value)/(old value) -1) × 100%
= (58/50 -1) × 100% = (1.16 -1) × 100%
= 16%
Mr. Key's work hours increased 16% from last week to this.
Answer:
Total area = 29.8 sq. units
Step-by-step explanation:
<u>area of each triangle = sqrt(s * (s-a) * (s-b) * (s-c))</u>
to get the value of s, use the <u>semi-perimeter = s = perimeter / 2</u>
<u>Total area = area of triangle ABD + area of triangle ACD</u>
semi-perimeter of ABD = (3.48 + 8.66 + 8.6) / 2 = 10.37
semi-perimeter of ABD = (3.54 + 8.84 + 8.6) / 2 = 10.49
area of triangle ABD = sqrt(10.37 * (10.37-3.48) * (10.37-8.66) * (10.37-8.6))
area of triangle ABD = 14.7 sq. units
area of triangle ACD = sqrt(10.49 * (10.49-3.54) * (10.49-8.84) * (10.49-8.6))
area of triangle ACD = 15.08
Total area = 14.7 + 15.1
Total area = 29.8 sq. units
