trapecia [35]

Answer:

Step-by-step explanation:

Given that there are two vectors U = (-8,0,1)

V = (1,3,-3)

To find projection of u on V and also projection of V on U

First let us find the dot product U and V

U.V = $-8(1)+0(3)+1(-3)\\= -11$

Projection of U on V = $\frac{U.V}{|V|} \\=\frac{-11}{\sqrt{1+9+9} } \\=\frac{-11}{\sqrt{19} }$

Similarly projection of V on U

= $\frac{U.V}{|U|} \\=\frac{-11}{\sqrt{64+0+1} } \\=\frac{-11}{\sqrt{65} }$

Which of the following function types exhibit the end behavior (PICTURE INCLUDED)

Nostrana [21]

Answer:

$y=x^n$ ; $n$ is even and greater than zero.

The absolute value function $y=|x|$

Step-by-step explanation:

The power function;

$y=x^n$ ; $n$ is even and greater than zero, is symmetric with respect to the positive y-axis.

As $x\rightarrow \infty,f(x)\rightarrow \infty$ and as $x\rightarrow -\infty,f(x)\rightarrow \infty$

The absolute value function $y=|x|$ also has the same end behavior.

The remaining functions in the options provided do not exhibit this end behavior.

See graph in attachment.

Given the function f(x)=2x-1<br> Evaluate: <br>a) 2f(x) <br> b) f(2x)

Dmitrij [34]

Answer:

a) 2f(x) = 4x - 2

b) f(2x) = 4x - 1

Explanation:

Given function:

f(x) = 2x - 1

a) 2f(x)

2f(x) = 2(2x - 1)

= 4x - 2

b) f(2x)

f(2x) = 2(2x) - 1

= 4x - 1

A basketball player has a 50% chance of making each free-throw. What is the probability that the player makes at least 11 out of

vitfil [10]

Answer:

100/2048=0.048828125%

Step-by-step explanation:

He has a 50% chance of making each free-throw, so 1/2*1/2*1/2*1/2*1/2*1/2*1/2*1/2*1/2*1/2*1/2=1/(2^11)=1/2048

to get a percentage you time by 100 to get 100/2048
