Answer:
5x4
Step-by-step explanation:
5x4=20
P = 12.
So,
15(12) + 70V < 400
V < (400 - 180)/17
V <3.14
So the max number of video can fit is 3.
Answer:
a) P=2(L+W)
b)
c)-2 inch/hour
Step-by-step explanation:
given:
length of the rectangle as L inches
width of the rectangle as W inches
a) The perimeter is defined as <u>the measure of the exterior boundaries</u>
therefore, for the rectangle the perimeter 'P' will be
P= length of AB+BC+CD+DA (A,B,C and D are marked on the figure attached)
Now from figure
P= L+W+L+W
OR
=> P=2L+2W .....................(1)
b)now dp/dt can be found as by differentiating the equation (1)
.............(2)
c)Now it is given for the part c of the question that
L=40 inches
W=104 inches
dL/dt=2 inches/hour
dW/dt= -3 inches/hour (here the negative sign depicts the decrease in the dimension)
substituting the above values in the equation (2) we get
Since there is four person, just ÷2 all of the required ingredients
We have that
1)<span>Circle W has center (−3, 0) and radius 8
the equation of a circle W is
(x+3)</span>²+(y)²=8²
2)<span>Circle V is a translation of circle W, 2 units down.
the center of circle V--------> (-3,0-2)---------> (-3,-2)
3)</span><span>Circle V is a dilation of circle W with a scale factor of 2.
then the radius circle V is 8*2------> 16 units
</span>the equation of a circle V is
(x+3)²+(y+2)²=16²
therefore
case <span>A. Circle V and circle W are similar.---------> is correct
</span>because I can transform circle V to circle W using only translations, rotations and scaling (In the case of circles, no rotations are necessary).
case <span>B. Circle V and circle W have the same center.-------> is not correct
case </span><span>C. The radius of circle V is 16.-----------> is correct
case </span><span>D. The center of circle V is (−5, 0).----------> is not correct
the answer is
</span> case A. Circle V and circle W are similar.---------> is correct
case C. The radius of circle V is 16.-----------> is correct
