One teacher wants to give each student 1 1/5 slices of pizza. If the teacher has 12 slices of pizza, then how many students will

yKpoI14uk [10]

Answer:

Step-by-step explanation:

You just have to convert the fraction into numerical form.

1 and 1/5

change it to

1 and 2/10

so 1.2

You then divide 12 by 1.2 which gives you 10.

Will give brainliest answer please help

Oxana [17]

Answer:

$a^{2}(24a^{2}+36a+12)$

Step-by-step explanation:

Area of rectangle= Length*Width

so $(6a^{2}+9a+3)*4a^{2}$ multiply each coefficient of a times 4a^2

$24a^{4}+36a^{3}+12a^{2}$ then take a^2 common factor so it will be

$a^{2}(24a^{2}+36a+12)$ =area

Find parametric equations for the path of a particle that moves along the circle x2 + (y − 1)2 = 16 in the manner described. (En

ArbitrLikvidat [17]

Answer:

a) $x = 4\cdot \cos t$ , $y = 1 + 4\cdot \sin t$ , b) $x = 4\cdot \cos t$ , $y = 1 + 4\cdot \sin t$ , c) $x = 4\cdot \cos \left(t+\frac{\pi}{2} \right)$ , $y = 1 + 4\cdot \sin \left(t + \frac{\pi}{2} \right)$ .

Step-by-step explanation:

The equation of the circle is:

$x^{2} + (y-1)^{2} = 16$

After some algebraic and trigonometric handling:

$\frac{x^{2}}{16} + \frac{(y-1)^{2}}{16} = 1$

$\frac{x^{2}}{16} + \frac{(y-1)^{2}}{16} = \cos^{2} t + \sin^{2} t$

Where:

$\frac{x}{4} = \cos t$

$\frac{y-1}{4} = \sin t$

Finally,

$x = 4\cdot \cos t$

$y = 1 + 4\cdot \sin t$

a) $x = 4\cdot \cos t$ , $y = 1 + 4\cdot \sin t$ .

b) $x = 4\cdot \cos t$ , $y = 1 + 4\cdot \sin t$ .

c) $x = 4\cdot \cos t''$ , $y = 1 + 4\cdot \sin t''$

Where:

$4\cdot \cos t' = 0$

$1 + 4\cdot \sin t' = 5$

The solution is $t' = \frac{\pi}{2}$

The parametric equations are:

$x = 4\cdot \cos \left(t+\frac{\pi}{2} \right)$

$y = 1 + 4\cdot \sin \left(t + \frac{\pi}{2} \right)$
