Answer:
Bot 2
Step-by-step explanation:
Lets find both robots rate per second.
Bot 1:
16 / 2 = 8 clicks per second
Bot 2:
30 / 3 = 10 clicks per second
Now multiply by 10 to see who clicks the most.
Bot 1:
8 * 10 = 80 clicks in 10 seconds
Bot 2:
10 * 10 = 100 clicks in 10 seconds.
With this information, its clear that bot 2 clicks the most in the least amount of time.
Best of Luck!

how would I graph this correctly?
Answer:
You would shade the fourth quadrant (bottom right).
Step-by-step explanation:
Due to the domain and range sets, you're given the facts that x must be greater than or equal to 0, but y is less than or equal to zero. This gives you what quadrant the graph should be in. Since you're not given an equation to follow like y=ax+b, then I can not say that this will give you a line.
f(x)=-x^2+3 find f(-2)
Answer:
f(-2) = - 1
Step-by-step explanation:
you could begin by understanding that f(x) is an alternate and informative version of y = -x^ + 3
The difference (critical) is that f(x) tells you how to substitute for x on the right.
You need to pay attention to doing something with - 2
f(-2) = - (-2)^2 + 3
Notice what you did. Wherever there is an x on the right, you put in a -2.
f(-2) = - (4) + 3
f(-2) = - 1

If f(x) = 10x - 5, what is f-1(f(3))?
Answer:
if the question is what is f(x) -1 ( f(x) )
then the answer is;
=10x-5 -1[10(3)-5]
=10x-5 -1(30-5)
=10x-5-1(25)
=10x-5-25
=10x-30

PLEASE IF YOU CAN I'D APPRECIATE ALL HELP. THIS IS MY LAST ATTEMPT AT IT AND IT'S DUE SOON.
Answer:
114°
Step-by-step explanation:
(x+95)°=6x°[being vertically opposite angles]
or, 95=6x-x
or, 95= 5x
or, 95/5 = x
or, 19 = x
Then,
(x+95)°
= 19+95°
= 114°
Answer:
114 Degrees
Step-by-step explanation:
x=19
You do this by setting (x+95)=6x and then solving for x.

Answer:
Step-by-step explanation:
When the numerator is more than the denominator the fraction is more (> 1) than one.
If the numerator is less than the denominator the fraction is less ( < 1 ) than one.
1/2 : 53/100 = 100/106 (< 1)
1/2 : 13/22 = 22/26 ( < 1 )
1/2 : 24/50 = 50/48 ( > 1 )
1/2 : 47/100 = 100/94 ( > 1 )

Geometry problem help!
Please refer to the image below...
Answer:
A. 1/3
B. √10
C. -1, 1
D. √8, 6
E. congruent and opposite pairs parallel
F. perpendicular, not congruent
G. rhombus, explanation below
Step-by-step explanation:
Hey there! I'm happy to help!
-----------------------------------------------------------------
A.
Slope is the rise over the run. Let's look at F to G.
We are going from -1 to 2 on our x-axis (run), so our run is 3 units.
Our rise is 1 unit as we go from 2 to 3 on the y-axis.
[tex]slope=\frac{rise}{run} =\frac{1}{3}[/tex]
This slope is the same for all of the sides.
-----------------------------------------------------------------
B.
We will use the distance formula (which is basically just the Pythagorean Theorem) to calculate the length of each side. Let's go between F and G again, but this distance is the same for all the sides.
[tex]\sqrt{(x_{2}-x_1)^2+(y_{2}-y_1)^2 } \\\\(x_1,y_1)=(-1,2)\\\\(x_2,y_2)=(2,3)\\\\\\\sqrt{(2+1)^2+(3-2)^2 } \\\\\sqrt{(3)^2+(1)^2 }\\\\\sqrt{9+1 }\\\\\sqrt{10}[/tex]
-----------------------------------------------------------------
C.
The diagonals are the lines that connect the non-adjacent vertices.
Our two diagonals are FH and GE.
-----------------------------
FH
We go from x-value -1 to 1 from F to H, so our run is 2.
We go from y-value 2 to 0. so our rise is -2.
[tex]slope=\frac{rise}{run} =-\frac{2}{2} =-1[/tex]
-----------------------------
GE
We go from x-value -2 to 2 from E to G, so our run is 4.
We go from y-value -1 to 3. so our rise is 4.
[tex]slope=\frac{rise}{run} =\frac{4}{4} =1[/tex]
-----------------------------------------------------------------
D.
Let's use the distance formula on each of our diagonals.
-----------------------------
FH
[tex]\sqrt{(x_{2}-x_1)^2+(y_{2}-y_1)^2 } \\\\(x_1,y_1)=(-1,2)\\\\(x_2,y_2)=(1,0)\\\\\\\sqrt{(1+1)^2+(0-2)^2 } \\\\\sqrt{(2)^2+(-2)^2 }\\\\\sqrt{4+4 }\\\\\sqrt{8}[/tex]
-----------------------------
GE
[tex]\sqrt{(x_{2}-x_1)^2+(y_{2}-y_1)^2 } \\\\(x_1,y_1)=(-2,-1)\\\\(x_2,y_2)=(2,3)\\\\\\\sqrt{(2+2)^2+(3+1)^2 } \\\\\sqrt{(4)^2+(4)^2 }\\\\\sqrt{16+16 }\\\\\sqrt{36}\\\\6[/tex]
-----------------------------------------------------------------
E.
They are congruent as they all have the same length (√10) and the opposite sides are parallel as they have the same slope (1/3)
-----------------------------------------------------------------
F.
They are perpendicular diagonals as their slopes are negative reciprocals (1 and -1), and they are not congruent as they have different lengths (√8 and 6).
-----------------------------------------------------------------
G.
Parallelogram- quadrilateral with opposite pairs of parallel sides.
Rhombus- a parallelogram with four equal sides
Square- a rhombus with four right angles
We can see that this is a parallelogram as we saw that the opposite sides are parallel due to having the same slope, and the perpendicular diagonals show that as well. This is also a rhombus because if we use that distance formula on all the sides, it will be the same. It is not a square though because it does not have four right angles, so this is a rhombus.
-----------------------------------------------------------------
Have a wonderful day and keep on learning!

Answer:
|x| = 8
Answer: x = 8, -8
Step-by-step explanation:
| | this symbol represents absolute value. When you remove absolute value it creates a ± sign on the opposite side.
x = ± 8
This means x = 8 and x = -8
The solutions are 8 and -8.

Let x represent the side length of a square. Find a regular polygon with side length x whose perimeter is twice the perimeter of the square. Find a regular polygon with side length x whose perimeter is three times the length of the square
Answer:
Step-by-step explanation:t55
An octagon has 8 sides. If each of them has a length of x, then the perimeter is 8x which is twice the perimeter of the square. (The square has a perimeter of 4x)
A dodecagon is a 12 sided regular polygon. It will have 12 sides all of which are equal to x. Since the square has a perimeter of 4x and the dodecagon has a perimeter of 12x the perimeter of the dodecagon is 3 times that of the given square.
