Answer:

bot 2

Step-by-step explanation:

first find out how many clicks they do in 1 second

16 ÷ 2 = 8

30 ÷ 3 = 10

so know we know that bot 2 clicks 2 more rimes in a second than bot 1

so if we times both the numbers by 10 to find out how many times they click in 10 secs

so bot 1 clicks 80 times

bot 2 clicks 100

Lane went to the bookstore he spent 1/3 of his money on a pen and 4/6 of it on books what fraction of his money did he have left

Mumz [18]

Answer: I believe that it might be $1.00

Step-by-step explanation: Well the problem doesn’t tell you how much money he HAD, so if you do 1/3+4/6 you should get 6/6 or 1 as the amount that Lane had.

Vector question. Let v=<-2,1> u=<3,-5> , find:

lyudmila [28]

Answer:

1. ) $\vec {v}.\vec{u}= -11$

2.) The angle between v and u is 147.52°.

Step-by-step explanation:

Given:

$\vec {v}= ( -2 , 1 )\\\vec {u}= ( 3 , -5 )$

To Find:

1. $\vec {v}.\vec{u}= ?$

2. $\theta = ?$

Solution:

$\vec {v}.\vec{u}$ is scalar product given as,

$\vec {v}.\vec{u}=|\vec {v}||\vec {u}|\cos \theta$

$|\vec {v}|=|(-2, 1)|=\sqrt{(-2)^{2} +1^{2}}=\sqrt{5}\\|\vec {u}|=|(3, 5)|=\sqrt{(3)^{2} +(-5)^{2}}=\sqrt{34}$

$\vec {v}.\vec{u}=(-2i +j).(3i-5j)\\$

Here only i.i = j.j =1 and i.j = j.i = 0

∴ $\vec {v}.\vec{u}=(-2\times 3 +1\times -5)\\\vec {v}.\vec{u}=-6-5=-11 \\$

Now, Substituting the above values we get

$-11=\sqrt{5}\times \sqrt{34}\cos \theta\\ \cos \theta=\frac{-11}{\sqrt{170}} \\ \cos \theta =-0.84366\\\therefore \theta =cos^{-1}(-0.84366)\\\therefore \theta =147.52\°$

As it is negative mean $\theta$ is in Second Quadrant Because Cosine is negative in Second Quadrant.

1. ) $\vec {v}.\vec{u}= -11$

2.) The angle between v and u is 147.52°.

If the complement of an angle measures 22 degrees what is the measure of its supplement?

sergiy2304 [10]

The complement of an angle is
angle+complement=90 degrees

angle+supplement=180

so if angle+22=90
subtract 22
angle=68

supplement=

68+supplement=180
subtract 68
supplement=112

The graph of a function f(x)=5to the power of x -5 contains the point (2,y) what is the value of y

Mila [183]

I believe this this the function.

$f(x) = {5}^{x - 5}$
