Answer:

The 3rd one again

Step-by-step explanation:

(a+−2)(8 $a^{2}$ +−5a+3)

=(a)(8 $a^{2}$ )+(a)(−5a)+(a)(3)+(−2)(8 $a^{2}$ )+(−2)(−5a)+(−2)(3)

=8 $a^{3}$ −5 $a^{2}$ +3a−16 $a^{2}$ +10a−6

=8 $a^{3}$ −21 $a^{2}$ +13a−6

hope this helped:)

Suppose you place 16 green, 25 blue, and 9 yellow marbles in a non-transparent bag. you then randomize the marbles by shaking th

Leni [432]

Answer: $\frac{12}{49}$

Step-by-step explanation:

16 green + 25 blue + 9 yellow = 50 Total

First pick: 25 blue out of 50 total = $\frac{25}{50} = \frac{1}{2}$

Second Pick: 24 blue out of 49 total = $\frac{24}{49}$

First Pick AND Second Pick

$\frac{1}{2}$ x $\frac{24}{49}$ = $\frac{24}{(2)49}$ = $\frac{12}{49}$

A clown is shot out of cannon with a velocity of 200 feet per second at an angle of 24°

Nadusha1986 [10]

Answer:

Vertical component of velocity is $81.35 ft/sec.$

Horizontal component of velocity is $182.6 ft/sec$ .

Step-by-step explanation:

Horizontal component of velocity is defined as:

$v_{x} = v\times cos\theta$

Vertical component of velocity is defined as:

$v_{y} = v\times sin\theta$

Where $v_{x} , v_{y}$ are the horizontal and vertical components of velocity.

$v$ is the actual velocity and

$\theta$ is the angle with horizontal axis at which the object was thrown.

Here, we are provided with the following:

$v = 200 ft/sec$

$\theta = 24^\circ$

$v_{x} = 200 \times cos24^\circ\\\Rightarrow 200 \times 0.913\\\Rightarrow v_{x} = 182.6 ft/sec$

$v_{y} = 200 \times sin24^\circ\\\Rightarrow 200 \times 0.407\\\Rightarrow v_{y} = 81.35 ft/sec$

So, Vertical component of velocity is $81.35 ft/sec.$

Horizontal component of velocity is $182.6 ft/sec$ .
