Answer:
Greater.
Step-by-step explanation:
The in the function
, the square root term
has to give a real number if
is to be real. This can only happen if
because if
then
will give a complex number and therefore
will not be real.
Thus, the domain for f(x) is all real numbers<em><u> greater</u></em><u> </u>than or equal to 2.
It is -11.34
-$68.04 divide by 6 is -$11.34, so instead of 11.34, it's -11.34
Area = perimeter + 132.
Let each side of the city be x miles long, then:-
x^2 = 4x + 132
x^2 - 4x - 132 = 0
x = [-(-4) +/- sqrt((-4)^2 - 4 * 1 *-132)] / 2
x = 13.66, -9.66 We ignore the negative
So the city has dimension of 13.66 * 13.66
13.7 * 13.7 to nearest 10th
Answer:
The revenue for Granton location is 175 thousand dollars
Step-by-step explanation:
Given
Cedarton 121
Rimber 189
Linton 147
Mean = 158
Required
Revenue for Granton location.
To calculate the revenue for Granton location, we make use of mean formula.
Mean is calculated by Summation of Observation divided by number of observations.
Since Granton location is unknown; Let it be represented by letter G.
So, the summation of observation becomes 121 + 189 + 147 + G
Summation = 457 + G
The number of observations = 4
Recall that Mean = Summation ÷ Number
By substituting 158 for mean, 457 + G for summation and 4 for number, we have
158 = (457 + G) ÷ 4
158 = ¼(457 + G)
Multiply both sides by 4
4 * 158 = = 4 * ¼(457 + G)
632 = 457 + G
Make G the subject of formula
G = 632 - 457
G = 175
Hence, the revenue for Granton location is 175 thousand dollars
<span>●(a + b)^2 = (a +b) (a +b)
(a + b) (a + b) = a*a + a*b + b*a+ b*b = a^2 + 2ab + b^2
●(a – b)^2 (a - b) (a -b)
(a - b) (a -b) = a*a + -ab - ba + b*b = a^2 - 2ab + b^2
●(a - b)(a + b). =
= (a - b) (a + b) = a*a + ab - ba - b*b = a^2 - b^2
