Write an equation to present her daily earnings?
Let daily sales be represented by x and daily earnings be represented by y.
y is calculated as thus;
Convert percentage to decimal
Hence, her daily earnings is
The answer is B) 20
Because you have 5 brands and you combine each with the 4 others, so 5*4=20
Since you mentioned calculus, perhaps you're supposed to find the area by integration.
The square is circumscribed by a circle of radius 6, so its diagonal (equal to the diameter) has length 12. The lengths of a square's side and its diagonal occur in a ratio of 1 to sqrt(2), so the square has side length 6sqrt(2). This means its sides occur on the lines 
and 
.
Let 
be the region bounded by the line 
and the circle 
(the rightmost blue region). The right side of the circle can be expressed in terms of 
as a function of 
:
Then the area of this circular segment is
Substitute 
, so that 
Then the area of the entire blue region is 4 times this, a total of 
.
Alternatively, you can compute the area of in polar coordinates. The line becomes 
, while the circle is given by 
. The two curves intersect at 
, so that
so again the total area would be 
.
Or you can omit using calculus altogether and rely on some basic geometric facts. The region is a circular segment subtended by a central angle of 
radians. Then its area is
so the total area is, once again, .
An even simpler way is to subtract the area of the square from the area of the circle.
Answer:
Slope = -1.5
Step-by-step explanation:
The two points are: (1, 1) and (3, -2)
Slope = (-2 - 1) / (3 - 1)
Slope = -1.5
Answer:
Option B
Step-by-step explanation:
Let's take a vertex G of quadrilateral GHJK to understand the rule for the translation,
From the graph attached,
Coordinates of G → (-5, 5)
Coordinates of the image point G' after the translation → G'(-5, 5)
Let the point G is translated 'a' units to the right and 'b' units down,
Rule for this translation,
G(x, y) → G'(x + a, y - a)
By this rule,
G(-5, 5) → G'(-5 + a, 5 - a)
-5 + a = -5 ⇒ a = 0
5 - a = 5 ⇒ a = 0
Therefore, vector that defines the translation will be,
<0, 0>
Option B is the the correct option.
