Answer:

28.26

Step-by-step explanation:

area of a circle is (pi)(r)^2

radius is half of the diameter

6/2=3

3 feet is the radius

a= 3.14 (3)^2

=3.14 x 9

= 28.26 feet

Hi!

-------------------------------------------------------------------------------------------------------------

Area of a circle = \pi r^2

Radius (r) = \frac{diameter}{2}

-------------------------------------------------------------------------------------------------------------

In this problem:

r= \frac{6}{2}

r= 3

3.14 (3)^2

3.14(9)

28.26

A report states that the mean household income last year for a certain rural county was $46,200 and the median was $54,500. If a
Masja [62]

Answer:

skewed to the left

Step-by-step explanation:

A histogram is used to represent data graphically. the histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval. the frequency is usually on the vertical axis while the class interval is usually on the horizontal axis.

If the mean is greater than the median, the histogram would be skewed to the right

If the mean is less than the median, the histogram would be skewed to the left.

The mean in this question is $46,200 while the median is $54,500. So, the histogram would be skewed to the left

Find the value of x that makes A||B
neonofarm [45]

Answer:

x = 10

Step-by-step explanation:

(4x)° & (3x+10)° are corresponding angles. If both the angles will be equal , then we can say that A║B.

4x=3x+10\\=>4x-3x=10\\=>x=10

If the value of x will be 10 , then it will make A║B.

Calculus help needed!
mezya [45]

f(x)=\ln x\\\\g(x)=\ln11x=\ln11+\ln x\ \ (\ln11=const.)\\\\h(x)=\ln x^2=2\ln x\\\\p(x)=\ln3x^2=\ln 3+\ln x^2=\ln3+2\ln x\ \ (\ln3=const.)

Used:

\ln a+\ln b=\ln(ab)\\\\\ln a^n=n\log a


Functions have the same derivatives if they differ a constant.

h(x) = f(x); g(x) = f(x) + const.

h'(x) = f'(x)

g'(x) = (f(x) + const.)' = f'(x) + (const.)' = f'(x) + 0 = f'(x)

h'(x) = g'(x)


Therefore yuor answer is A. f'(x)=g'(x)



f'(x)=(\ln x)'=\dfrac{1}{x}\\\\g'(x)=(\ln11x)=\dfrac{1}{11x}\cdot11=\dfrac{1}{x}

Used:

(\ln x)'=\dfrac{1}{x}\\\\f'(g(x))=f'(g(x))\cdot g'(x)
