Answer:
<h2>
70cm/s</h2>
Step-by-step explanation:
Area of a square with side of length L is expressed as A = L². The rate at which the area is increasing will be expressed as dA/dt.
dA/dt = dA/dL * dL/dt where
dL/dt is the rate at which each side of the square is increasing.
Since dA/dL = 2L, dA/dt = 2L dL/dt
Given dL/dt = 5cm/s and the Area of the square = 49 cm²
49 = L²
L = √49
L = 7cm
dA/dt = 2(7) * 5
dA/dt = 14*5
dA/dt = 70cm/s
The rate at which the area of the square is increasing is 70cm/s
Answer:
4 ml
Step-by-step explanation:
m = D/ v where m is mass and D is density and V is volume
.875 = 3.5 / V
Multiply each side by V
.875 V = 3.5
Divide each side by .875
V = 3.5/.875
V =4

Step-by-step explanation:
Answer:
A least-squares solution of is a vector such that for all in .
C. The statement is true because the general least-squares problem attempts to find an that maximizes .
Step-by-step explanation:
The above statement is actually the one that validates the least-square solution statement.
