Answer:
- ac = -16
- b = 0
- -4, 4
- (4x -1)(4x +1)
Step-by-step explanation:
a) ac is the product of the leading coefficient (16) and the constant (-1).
ac = (16)(-1) = -16
__
b) b is the coefficient of x. There is no x term, so ...
b = 0
__
c) Two factors that add to give zero must be opposites. That is, they must be the square root of the opposite of -16, and the opposite of that.
the two numbers are -4 and 4
__
d) The factored form for the two numbers p and q just found is ...
ax^2 +bx +c = (ax +p)(ax +q)/a
= (16x -4)(16x +4)/16
= (4x -1)(4x +1) . . . . factored form of 16x^2 -1
The length of side a is c:8
Now Tim gets $500 after it $45 was added to what he had last week
That means that
"What Tim earned last week" + $45 = $500
Subtract $45 from $500
$500-$45= $455
If you're not sure check your work
If I make $455 now and next week I get $45 more next week
$455+$45=$500
Next week I make $500
Answer:
Theory
Step-by-step explanation:
The term theory is associated to a "set of logical interrelated concepts, statements, propositions, and definitions", who are "derived from philosophical and logical beliefs from scientific data and from which questions and hypotheses can be deduced, characterize, tested and verified".
So then we can conclude that :
A set of logically interrelated concepts, statements, propositions, and definitions supported by data, testing, and verification to account for or characterize some phenomena is called theory.
