No. It is not a square. Clearly this quadrilateral does not match all of the critera needed to fit the image/idea of a square. Although all of the vertices are 90 degree angles and the polygon is indeed a quadrilateral, the sides of the figure are not all the same length. That image is not one of squarish preportions. Therfore, it is not a square.

P.S. I tried to add in mathmatic words. Im not that much of a knowitall. Hope they get u an A+!!!

A point on the rim of a wheel has a linear speed of 33 cm/s. If the radius of the wheel is 50 cm, what is the angular speed of t

Zigmanuir [339]

Answer:

The angular speed of the wheel in radians per second is 0.66.

Step-by-step explanation:

Recall the following statement:

A linear speed (v) is given by,

$v=\omega \times r$ ...... (1)

Here, $\omega$ represents the angular speed of the wheel and r represents the radius of the wheel.

From the given information:

Linear speed (v) = 33 cm/s

Radius of the wheel (r) = 50 cm

Now to find the angular speed in radian per second.

$33 =50 \times \omega$

Divide both sides by 50.

$0.66 rad/sec= \omega$

Hence, the angular speed of the wheel in radians per second is 0.66.

Answer:

Step-by-step explanation:

f'(x)=-sin x

$f'(x)=\frac{cos \frac{\pi }{3} -cos (\frac{-\pi }{3}) }{\frac{\pi }{3} -(\frac{-\pi }{3}) } \\-sin x=\frac{\frac{1}{2} -\frac{1}{2} }{\frac{\pi }{3} +\frac{\pi }{3} } \\sin x=0\\at x=c ,sin c=0,c=0$

c=0∈(-π/3,π/3)

3x +15 = 2x + 10 + x + 5

Shkiper50 [21]

Answer:

The equation is true.

Step-by-step explanation:

Simplify. Combine like terms:

3x + 15 = (2x + x) + (10 + 5)

3x + 15 = (3x) + 15

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3x and 15 from both sides:

3x (-3x) + 15 (-15) = 3x (-3x) + 15 (-15)

3x - 3x = 15 - 15

0 = 0

~ True. The two expressions are equal to each other.
