Answer:
The greatest value of the expression 1-x^2 is 1
Step-by-step explanation:
Here, we want to find the greatest value of the integer 1-x^2
We should understand that when we talk of integers, we are referring to whole numbers.
We should understand that 0 is also an integer.
Apart from zero, any other integer we substitute for x will give the function a negative value. Only 0 will make sure that the value remains positive and as such gives the function its highest possible value
So therefore;
1-0^2 = 1-0 = 1
Hence, the greatest possible value of the expression is 1
Elemantary school so
area=legnth times width
to get greatest area, make legnth as close to width as possible in measure
to get least area, make legnth as far away from width as possible in measure
perimiter=2 times legnth+2 times width=2 times (legnth+width)
18=2 times (legnth+width)
divide 2
9=legnth+width
find closest and farthest
1+9 is farthest
4+5 is closest
areas=legnth times with
1 times 9=9
4 times 5=20
differnce is subtract
20-9=11
answe is 11
(note I didn't use decimals since the user is supposedly in elemenatry school)
Answer:
C and E
Step-by-step explanation:
We are given that



A.

Hence, it is not in proportional relationship with (0.2,0.3)
B.(2.7,4.3)


Hence, it is not in proportional relationship with (0.2,0.3).
C.(3.2,4.8)


Hence, the ordered pair (3.2,4.8) are in a proportional relationship with (0.2,0.3).
D.(3.5,5.3)

Hence, the ordered pair (3.5,5.3) are not in a proportional relationship with (0.2,0.3).
E.(5.2,7.8)

Hence, the ordered pair (5.2,7.8) are in a proportional relationship with (0.2,0.3).
Answer:
The percentage decrease is -33.93%
Step-by-step explanation:
Firstly we check if there is an increase or decrease
Since we went from 5.5 million to 3.7 million, that is a decrease
Percentage decrease = (3.7 - 5.6)/5.6 * 100%
= -1.9/5.6 * 100% = -33.93%
The mean should be about the same, because the sample is random
