Answer:
2. x
² + y
²
= 4
3. x² + y² = 23
Step-by-step explanation:
The equation of a circle with center
(
a
,
b
) and radius r is:
(
x
−
a
)²
+ (
y
−
b
)
² = r
²
Explanation:
Here,
a
=
0
, b
=
0
, r
=
2
The equation is:
(
x
-0
)
² + (
y
-0
)
² = (
2 )
²
that is: x
² + y
² = 4
Thus:
x
² + y
²
= 4
3. Each point on a circle has the same distance from the center. This distance is the radius r of the circle.
Here,
(
-3
,
4
) is a point on the circle, meaning that the radius of the circle is the distance between (
0
,
0
)
, the center, and (
-3
,
4
)
.
thus a circle centered on the origin will have an equation of:
x² + y² =r²
And, (
-3
,
4
) lies on the circle, we have:
(-3)² + (4)² = r²
9 + 14 = 23
substituting;
x² + y² = 23
20% of $19,400 is $3,880
($19,400 / 5 = $3,880)
subtract 20% from the original value
($19,400 - $3,880 = $15,520)
it's now worth $15,520
Answer:
Unit rate of oreos = 19.23 cents/oz
Unit rate of Chips Ahoy = 17.86 cents/oz
The cheapest and most affordable is the chips ahoy because it has a lower unit rate.
Step-by-step explanation:
Oreos 2.98 for 15.5.Oz or chips ahoy for 2.50 for 14.Oz I pick chips ahoy BUT ITS ASKING UNIT RATE CENTS PER OZ
We would be finding the Unit Rate of each product.
For Oreos
Oreos $2.98 for 15.5.Oz
We convert dollars to cents
1 dollars = 100 cents
2.98 dollars = x
x = 2.98 × 100 cents
= 298 cents
Hence, the unit rate in cents/oz
= 298 cents/15.5 oz
= 19.225806452 cents/oz
= 19.23 cents/oz
For Chips ahoy
$2.50 for 14.Oz
We convert dollars to cents
1 dollars = 100 cents
2.50 dollars = x
x = 2.50 × 100 cents
= 250 cents
Hence, the unit rate in cents/oz
= 250 cents/14 oz
= 17.857142857 cents/oz
= 17.86 cents/oz
Therefore, the cheapest and most affordable is the chips ahoy because it has a lower units rate.
4,800 and 60 looks to be what you're looking for.
Deuces!
