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


Answer:
it is A i could be wrong
Step-by-step explanation:
Answer:
2, 3, 4, 7
Step-by-step explanation:
there is no information/data recorded from 7 - 9
10 is an outlier it is far from the rest of the data
there is a group of information/data from 0 - 2
there is not information/data at 3
hope this helps :)
<span>If (x, 7√3) is a point on the unit circle, then x2 + (7√3)2 = 1 and </span>-1 ≤ x ≤ 1. <span>So, x2 = 1- (7√3)2 = 1- 147 = -146</span> <span>Since there is no value of x where -1 ≤ x ≤ 1 and x2 = -146, the given point is NOT on the unit circle.
