Answer:
Option (4) and Option (5)
Step-by-step explanation:
By calculating the second difference, if the second difference in a table is equal, table will represent the quadratic relationship.
In the given option, we analyze that table given in Option (4) will represent the quadratic relationship.
x y Ist difference IInd difference
0 4 - -
1 -4 -4 - (4) = -8 -
2 -4 -4 - (-4) = 0 0 - (-8) = 8
3 4 4 - (-4) = 8 8 - 0 = 8
Second difference of the terms in y are the same as 8.
Therefore, table of Option (4) represents the quadratic relationship.
Similarly, in Option (5) we will calculate the second difference of y terms.
x y Ist difference IInd difference
0 -4 - -
1 -8 -8 - (-4) = -4 -
2 -10 -10 - (-8) = -2 -2 - (-4) = 2
3 -10 -10 - (-10) = 0 0 - (-2) = 2
Here the second difference is same as 2.
Therefore, table of Option (5) will represent the quadratic relationship.
<h2>Answer:</h2>
<em>(Check attached images).</em>
<h2>Step-by-step explanation:</h2><h3>Exercise 1.</h3>a. Convert to decimals.
To order the numbers from least to greaters, convert them to decimals and compare.
b. Select the second least number.
-0.8.
<h3>Exercise 2.</h3>a. Convert to decimals.
b. Select the correct number.
.
a. Convert to decimals.
<em>After seeing that there are negative and positive numbers, and with the premise that negative numbers are </em><u><em>always</em></u><em> lesser than positive numbers, we'll only compare the positive numbers.</em>
<em>59%=0.59</em>
<em>3/5=0.6</em>
<em />
b. Select the correct number.
3/5.
<h3>Exercise 4.</h3>a. Convert to decimals.
-0.35
-3.5%= -0.035
b. Conclude.
Seeing that -3.5% is less than -0.35, the symbol that makes the statement true is ">".
<h3>Exercise 5.</h3>a. Try to visually estimate b.
B appears to have a value of -0.9.
b. Convert the numbers to decimals.
-3.4%= -0.034
-0.031
-1/5= -0.2
c. Select the correct answer.
<em>Since we estimated the value of b as -0.9, the number that best adequates to its value is </em>.
a. Convert to decimals.
<em>After seeing that there are negative and positive numbers, and with the premise that negative numbers are </em><u><em>always</em></u><em> lesser than positive numbers, we'll only compare the positive numbers.</em>
5.2%= 0.052
1/7= 0.1429
b. Select the correct number.
5.2% is the second largest.
<h3>Exercise 7.</h3>a. Convert to decimals.
6/7= 0.857143
0.857
b. Select the correct answer.
Seeing that 0.857 is marked as an approximate by the
ellipsis, and considering that 6/7 is an irrational numbers, we can conclude that the number that better fits the situation and makes the statement true is "=".
<h3>Exercise 8.</h3>a. Convert to decimals.
<em>After seeing that there are negative and positive numbers, and with the premise that negative numbers are </em><u><em>always</em></u><em> lesser than positive numbers, we'll only compare the negative numbers.</em>
<em>-4.6</em>
<em />
b. Select the correct answer.
The smallest number is -4.6.
