Sammy has 2 pair of jeans, 3 pair of black pants, and 1 skirt. She also has 2 pink shirts, 4 striped shirts, and 2 hooded sweats

Diano4ka-milaya [45]

Answer: 72

Step-by-step explanation:

Ok, in her legs the options are:

2 jeans + 3 black pants + 1 skirt = 6 options.

on her torso the options are:

2 pinks shirts + 4 striped shirts = 6 options.

And on top of that she has:

2 hooded sweatshirts = 2 options.

The total number of combinations is equal to the product of options for each type of garmet; this is:

C = 6*6*2 =36*2 = 72

So she has 72 different outfits.

The height, h, in metres, of a rocket t seconds after it is launched is approximately modelled by the quadratic relation h = 80t

8_murik_8 [283]

Answer: 5 s

Step-by-step explanation:

Given

Height of the rocket can be modelled as $h=80-16t^2$

Rocket will land on earth when it's height becomes 0

$\Rightarrow 80t-16t^2=0\\\Rightarrow t(80-16t)=0\\\\\Rightarrow t=0\ \text{or}\ t=\dfrac{80}{16}=5\ s$

Neglecting 0 value

Thus, rocket remains in air for 5 s.
