Answer:
2+i or 2-i (D)
Step-by-step explanation:
First you use the quadratic formula. X= (-b +/-
)/2a
a=1
b=-4
c=5
X= (4 +/-
)/2
X=(4 +/-
)/2
The square root of -4 is 2i. i=√-1. Therefore 2i= 2√-1 .If you simplify that, it becomes √-4i.
X= (4+/- 2i)/2
X= 2+/-i
X= 2+i or 2-i
14.6 is the constant because no matter how many hours she will work (that number could change) it will always be a linear growth of 14.6.
Answer:
first one: B and C
Second one: x=12, y=10 so the answer is B.
Step-by-step explanation:
First one: Irrational numbers are any numbers that go on forever in the decimal without ever repeating. Any square roots of numbers that aren't perfectly square, such as 4 and 9, are irrational. And anything with pi, or
, is always irrational.
Second one: 144 and 100 are perfect squares, meaning it can be created by multiplying the same number by itself, in this case 12 and 10. Subtract those and you get 2.
Answer:
144
Step-by-step explanation:
so if we have 120 and we need to find out what the original prices we could add 20% of 120 which will get us to 144
The amount due for the first term of payment is the product of the
total sales and the percentage.
(1)
Amount
due = ($85,000)(0.04) = $3,400
The total amount due for the second term of payment is the product of
the total sales and the percentages together with all the fees specified in the
item (insurance, maintenance, and utilities).
(2)
Amount
due = ($85,000)(0.03) + $175 + $50 + $345 = $3,120
If we are to compare the two amounts, using the second term of
payment, lesser amount will be paid. Thus, the answer to this item is the
second choice.
