(x-1)(5x+2)

Step-by-step explanation:

5 $x^{2}$ + 2x - 5x - 2

(5 $x^{2}$ + 2x) (- 5x - 2)

x(5x + 2) -1(5x + 2)

(x-1)(5x+2)

5 less the quotient of 14 times a number x and 9

AURORKA [14]

Answer:

$\frac{14x}{9}-5$

Step-by-step explanation:

14 times a number x : 14* x = 14x

Quotient of 14 times a number x an 9 : $\frac{14x}{9}$

5 less the quotient of 14 times a number x and 9 :

$\frac{14x}{9}-5$

Gnoma [55]

Answer:

10 pairs

It is a combination

Explanation:

This is a combination because the order does not matter: the Beagle - Collie couple is the same as the Collie - Beagle couple, so it is only counted once.

The formula for combinations is:

$C(m,n)=\dfrac{m!}{n!\cdot (m-n)!}$

For five diffferent dogs to be put in pairs, the number of different pairs is:

$C(5,2)=\dfrac{5!}{2!\cdot (5-2)!}=\dfrac{5\times 4}{2}=10$

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.
