Answer:
The area is changing by the rate of 44.62 meters per sec.
Step-by-step explanation:
Let x be the side of the square and r be the radius of the circle,
Then, the area outside the circle but inside the square is,
V = Area of square - area of circle,
∵ Area of a square = side² and area of a circle = (radius)²,
Thus,
Differentiating with respect to t ( time )
We have,
x = 20 meters, r = 3 meters,
Answer:
a) The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9.

Answer:
DL = 5.87 un.
LN = 10.98 un.
DN = 14.4 un.
Step-by-step explanation:
<u>Given:</u>
∆DLN,
LF ⊥ DN ,
DF = 4
m∠N = 23º,
m∠D = 47º
<u>Find:</u>
DL, LN, DN
Solution:
In right triangle DFL, DF = 4, m∠D = 47º, so
and
In right triangle LFN, LF = 4.29 units, m∠N = 23º, so
and
Hence,
DN = 4.29 + 10.11 = 14.4 units

Step-by-step explanation:
3 gallons of blue paint and 5 gallons of yellow paint and this answer is a fraction so is the answer.
Answer:
See below in bold.
Step-by-step explanation:
Factored form:
f(x) = -5(x + 7)(x - 9)
Standard form:
f(x) = -5(x^2 + 7x - 9x - 63)
f(x) = -5(x^2 - 2x - 63)
f(x) = -5x^2 + 10x + 315.
