Area of a circle = pi*r^2

6*6*pi = 36pi = 113m2 C

Answer:

c. 113 m^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

Using 3.14 as an approximation for pi

A = 3.14 ( 6)^2

A = 3.14 *36

A =113.04

Answer:

total number of people on Friday = 285

total number of people on Saturday = 355

total increment = 355-285 = 70

total increase percentage = 70÷285*100

= 24.56%

hope it helps!

Can someone help me with this math hw ​
AveGali [126]

Answer:

Step-by-step explanation:

F(x) = x² - 2x + 1

      = (x - 1)²

By comparing this equation with the vertex form of the quadratic equation,

y = (x - h)² + k

Here, (h, k) is the vertex

Vertex of the parabola → (1, 0)

x-intercepts → (x - 1)² = 0

                       x = 1

y-intercepts → y = (0 - 1)²

                       y = 1

Now we can draw the graph of the given function,

From this graph,

As x → 0,

\lim_{x \to 0^{-}} (x-1)^2=1

\lim_{x \to 0^{+}} (x-1)^2=1

f(0) = (0 - 1)²

     = 1

Since, \lim_{x \to 0^{-}} (x-1)^2=\lim_{x \to 0^{+}} (x-1)^2=1

Therefore, given function is continuous at x = 0.

I cant solve this can i get some help? <br> 2 cos x + √ 2 = 0
Alexandra [31]

Answer:

Step-by-step explanation:

2 cos x + √ 2 = 0

2 cos x = -√ 2

cos x = -√ 2  / 2

x = arcCos(  -√ 2  / 2 )

so to solve we have to use  "co-terminal " angles .. do you know what I'm saying?  do you understand the words coming out of my mouth :DDDDD OKay back to math and not movie lines .. :P

x = arcCos(  √ 2  / 2 )

x = 45 °

now find the "co terminal" angle that is on 45 ° but in the correct quadrant... since the  -√ 2   is negative.. we now that we go down the y axis.. but also positive on the x axis.. soooo.. that put the angle in the 4th quadrant... so this is an angle of 315° if we go in the CCW  ( counter clock wise )  direction but it's also -45°  in the CW  (clock wise )  direction

below is the table to remember the trig special angles

notice how it's  1,2,3,4    .. so it's super easy to remember.. the trig books don't show you this "trick"   :P

copy and paste this to your computer some where handy

Sin(0) = 0/2      =0  

Sin(30)= \sqrt{1}/2   = 1/2  

Sing(45) =\sqrt{2}/2 =\sqrt{2}/2  

Sin(60)=\sqrt{3}/2   = \sqrt{3}/2  

Sin(90)=\sqrt{4}/2   = 1  

Cos is exactly the same but counts backwards from 90°

Cos(90) = 0/2       = 0

Cos(60) = \sqrt{1} /2   = 1/2

Cos(45) = \sqrt{2}/2    =\sqrt{2}/2

Cos(30) = \sqrt{3}/2   =\sqrt{3}/2

Cos(0) = \sqrt{4}/2    = 1
