If a car is traveling east when it passes the camera, will its position be positive or negative 60 seconds after it passes the camera? If we multiply two positive numbers, is the result positive or negative?
Step-by-step explanation:
I can only answer part 2 of your question, "If we multiply two positive numbers, is the result positive or negative?". if you multiply 2 positive numbers your answer would be positive.
If we multiply two positive numbers, then the result is also positive.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that If a car is traveling east when it passes the camera, then;
the position be positive 60 seconds after it passes the camera.
Therefore, If we multiply two positive numbers, then the result is also positive.

A coin is weighted so that the probability of heads is 0.64. On average, how many coin flips will it take for the tails to first appear
Answer:
1.563
Step-by-step explanation:
Given :
Probability of head, p = 0.64
Number of flips it would take for tail to appear first :
Treatting the question as a geometric function :
Using the relation :
1 / p
Expected number of flips until first tail :
1 / P = 1/ 0.64 = 1.5625
E(x) = expected number of flips until first tail = 1.563

I just need help with this one question, im having trouble with it. Find an equation of the line that is perpendicular to the line shown below and passes through the point (-4,5). Show your work.
Answer:
[tex]y=\frac{-1}{2}x +3[/tex]
Step-by-step explanation:
Take any two points from the graph
(2 , 0) ; (0 , -4)
Slope = [tex]\frac{-4-0}{0-2}\\\\[/tex]
[tex]= \frac{-4}{-2}\\\\= 2[/tex]
Slope of the perpendicular line = -1/m = -1/2 = -1/2
m = -1/2 ; (-4 , 5)
y - y1 = m(x - x1)
[tex]y - 5 = \frac{-1}{2}(x -[-4] )\\\\y - 5= \frac{-1}{2}(x + 4)\\\\y - 5 = \frac{-1}{2}x +\frac{-1}{2}*4\\\\y-5 = \frac{-1}{2}x -2\\\\y = \frac{-1}{2}x-2+5\\\\y=\frac{-1}{2}x + 3[/tex]

An open-top box with a square base is to have a volume of 4 cubic feet. Find the dimensions of the box (in ft) that can be made with the smallest amount of material.
Answer:
The dimension of box=[tex]2ft\times 2ft\times 1ft[/tex]
Step-by-step explanation:
We are given that
Volume of box=4 cubic feet
Let x be the side of square base and h be the height of box
Volume of box=[tex]lbh=x^2h[/tex]
[tex]4=x^2h[/tex]
[tex]h=\frac{4}{x^2}[/tex]
Now, surface area of box,A=[tex]x^2+4xh[/tex]
[tex]A=x^2+4x(\frac{4}{x^2})=x^2+\frac{16}{x}[/tex]
[tex]\frac{dA}{dx}=2x-\frac{16}{x^2}[/tex]
[tex]\frac{dA}{dx}=0[/tex]
[tex]2x-\frac{16}{x^2}=0[/tex]
[tex]2x=\frac{16}{x^2}[/tex]
[tex]x^3=8[/tex]
[tex]x=2[/tex]
[tex]\frac{d^2A}{dx^2}=2+\frac{32}{x^3}[/tex]
Substitute x=2
[tex]\frac{d^2A}{dx^2}=2+\frac{32}{2^3}=2+4=6>0[/tex]
Hence, the area of box is minimum at x=2
Therefore, side of square base,x=2 ft
Height of box,h=[tex]\frac{4}{2^2}=1 ft[/tex]
Hence, the dimension of box=[tex]2ft\times 2ft\times 1ft[/tex]
