Evaluate the summation of 3 times negative 2 to the n minus 1 power, from n equals 1 to 5. A) −93. B) −33. C) 33. D) 93

lions [1.4K]

∑ ( from n = 1 to n =5 ) 3 · ( -2 ) ^( n -1 )
a 1 = 3 · ( -2 ) ^0 = 3
a 2 = 3 · ( - 2 ) = - 6
a 3 = 3 · 4 = 12
a 4 = 3 · ( - 8 ) = - 24
a 5 = 3 · 16 = 48
3 - 6 + 12 - 24 + 48 = 33

Simplify the expression. State any excluded values.<br><br> x^ 2 - 36/42x - 7x^ 2

REY [17]

Consider the expression $x^2-\dfrac{36}{42}x-7x^2.$

This expression contains two terms with $x^2,$ group them:

$x^2-7x^2=x^2(1-7)=-6x^2.$

Now simplify term $\dfrac{36}{42}x=\dfrac{6}{7}x.$

Now $x^2-\dfrac{36}{42}x-7x^2=-6x^2-\dfrac{6}{7}x=6\left(-x^2-\dfrac{1}{7}x\right)=-6x\left(x-\dfrac{1}{7}\right).$

This expression is defined for all x.
