None of the pairs will deliver (g×f)(a). If you intend (g∘f)(a), then ...
... selection 3 is appropriate.
Answer:
d
Step-by-step explanation:
Let the first number be x and decide number be y
therefore x+y = -42
also. x-y = 52 using the process of elimination
we get: 2x = 10
we divide both sides by 2, which gives us x=5
then we substitute the value of x in the first equation
that gives us. 5+y = -42
thus. y = -47
Pat's fund earned is $526.40 more than Sam's fund.
Sam's investment :
9400*.052 = 488.80*7 = $3,421.60
Pat's investment :
9400*.06 = 564*7= $3,948.00
$3,948.00-$3,421.60=$562.40
The answer to your question is going to be D. $526.40.
Hope this helps you!!:))
You apply the rule to put the exponent in front, and lower it by one. But since this is a nested expression, you apply it twice:
4*(5x^3-4)^3 * 3*5x^2 =
60x^2 (5x^3-4)^3
