Answer:
Two of these statements are true.
The function equals x^2 over the interval −∞ < x ≤ 0.
The function equals √x over the interval 0 ≤ x < ∞.
Step-by-step explanation:
If we look at the parent function of 
we see that function looks like a U shaped graph and in your graph we see it is the same as your graph from the interval (-∞,0).
If we look at the parent function of 
we see that the
function looks like your graph from the interval (0,∞).
Suggestion:
I suggest memorizing every graph of parent functions that is introduced to you in math. This can help you visually with many problems in mathematics, and help you conceptualize material better. I also suggest looking up the definition of every word that may be unfamiliar to you like "interval" and "parent function". This will help you understand more advanced math notations and vocabulary in the future.
Answer:
grams
Step-by-step explanation:
kilometers is for length, milugrams are too small and millimeters dosent make sense
Answer:
20,000m²
Step-by-step explanation:
If they jog 12 km/h for half an hour, they have covered.
12 X 0.5 = 6km in 10 circuits. Making 1 perimeter
6 / 10 =0.6 km (600 m).
To determine area we need to convert this perimeter to length and width. We know that it is a rectangle, with 2 equal widths and 2 equal lengths, and the length is twice the width.
So L = 2W
Perimeter = 2W + 2L
600 m = 2W + 2(2W)
600 m = 6W
W = 100 m
L = 200 m
Area = 100 X 200 = 20,000 m²
<span>First of all to calculate the distance between two points we can use distance formula
d=Square Root [(x2-x1)^2 + (y2-y1)^2]
Now substitute the given points p(x1,y1) and q(x2,y2)in above distance formula
The values are X2=3, X1=8and Y2=8and Y1=2.
After Substituting the values
d=Square Root[(-5)^2+(6)^2]
d=Square Root(25+36]
d=Square Root[61]
d=7.8
7.8 is the distance between points P(8, 2) and Q(3, 8) to the nearest tenth.</span>
