Answer:
9
Step-by-step explanation:
First off you need to find the interval that four falls in.
Four is not less than three so you can rule out the first one, four is not greater than 10 so you can rule out the last one. But four is greater than three and less than ten, so it falls in the second interval.
So, now you can substitute four in for x for the second equation
4^2-7
16-7
=9
Answer:
84 Percentage increase
Step-by-step explanation:
Detailed calculations & verification
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
40% = 40/100 = 40 ÷ 100 = 0.4.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 40% of its value.
Percentage increase = 40% × 210
New value = 210 + Percentage increase
Calculate the New Value
New value =
210 + Percentage increase =
210 + (40% × 210) =
210 + 40% × 210 =
(1 + 40%) × 210 =
(100% + 40%) × 210 =
140% × 210 =
140 ÷ 100 × 210 =
140 × 210 ÷ 100 =
29,400 ÷ 100 =
294
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 210 =
294 - 210 =
84
1) Write the number in exponential form with a base of 10:
3√1000 = 3√10^3
2) Reduce the index of radical and exponent with 3:
3√10^3=10
