Answer 1

So sorry I replied so late but I'll leave the answer here just in case.

Answer:

7. Domain: [0,30]  Range: [0,7]

8. f(20) = 4.67 or 4 2/3; After 20 seconds, the squirrel is 4.67 meters away from the camera.

9. x = 1.25 and x = 21.43; The quirrel is 4 meters away from the camera at 1.25 seconds and 21.43 seconds.

10. At 2.5 and 19.29 seconds

11. 10 seconds

12. The squirrel went to the back of the camera, away from its line of view.

Step-by-step explanation:

7. The line is between 0 and 30 on the x-axis and is between 0 and 7 on the y-axis.

8. The slope of the third part of the line is not a whole number, so you need to calculate it. The rise is -7 meters and run is 15 seconds, so the slope is -7/15. Plugin -7/15 into the slope-intercept form (y = mx+b) and the equation is f(x) = -7/15 x+14. Plugin x=20 into the equation:

f(20) = -7/15(20)+14

f(20) = -9.33+14

f(20) = 4.67

9. The first slope of the graph will also need to be calculated. Rise is 7-3 (4) and the run is 5. Slope = rise/run = 4/5 = 0.8. Plugin the slope into y = mx+b with the y-intercept, and the equation is f(x) = 0.8x+3. Replace f(x) with 4 and solve the equation.

4 = 0.8x+3

1 = 0.8x

x = 1.25

There is another x value that matches with f(x) = 4 in the third part of the graph, so we'll use the slope-intercept form for the previous question for this one.

4 = -7/15 x+14

-10 = -7/15 x

x = 21.43

10. The squirel is 5 meters away from the camera twice, so we'll be using the same equations for the previous question.

5 = 0.8x+3

2 = 0.8x

x = 2.5

5 = -7/15 x+14

-9 = -7/15 x

x = 19.29

11. The squirrel is 7 meters away between 5 and 15 seconds. 15-5 = 10.

12. The squirrel most likely went somehwere where the camera can't see it, and it's probably the back of it.

Find the new set of coordinates given the scale factor for k > 1. E = (-1, -2), F = (2, -5), G = (5, -1), H = (1, 1) Scale factor = 6 E'= F' = G' = H' =

Answers

Answer:

The new set of coordinates are [tex]E'(x,y) = (-6,-12)[/tex], [tex]F'(x,y) = (12,-30)[/tex], [tex]G'(x,y) = (30,-6)[/tex] and [tex]H'(x,y) = (6,6)[/tex].

Step-by-step explanation:

Vectorially speaking, dilation can be defined by this equation:

[tex]D'(x,y) = O(x,y) +k\cdot (D(x,y)-O(x,y))[/tex] (1)

Where:

[tex]O(x,y)[/tex] - Center of dilation.

[tex]D(x,y)[/tex] - Original point.

[tex]k[/tex] - Scale factor.

[tex]D'(x,y)[/tex] - Dilated point.

Let suppose that center of dilation is located at origin, we determine the new set of coordinates below:

[tex]E'(x,y) = O(x,y) +k\cdot (E(x,y)-O(x,y))[/tex]

[tex]E'(x,y) = (0,0) +6\cdot (-1,-2)[/tex]

[tex]E'(x,y) = (-6,-12)[/tex]

[tex]F'(x,y) = O(x,y) + k\cdot (F(x,y)-O(x,y))[/tex]

[tex]F'(x,y) = (0,0) +6\cdot (2,-5)[/tex]

[tex]F'(x,y) = (12,-30)[/tex]

[tex]G'(x,y) = O(x,y) + k\cdot (G(x,y)-O(x,y))[/tex]

[tex]G'(x,y) = (0,0) + 6\cdot (5,-1)[/tex]

[tex]G'(x,y) = (30,-6)[/tex]

[tex]H'(x,y) = O(x,y) +k\cdot (H(x,y)-O(x,y))[/tex]

[tex]H'(x,y) = (0,0) + 6\cdot (1,1)[/tex]

[tex]H'(x,y) = (6,6)[/tex]

The new set of coordinates are [tex]E'(x,y) = (-6,-12)[/tex], [tex]F'(x,y) = (12,-30)[/tex], [tex]G'(x,y) = (30,-6)[/tex] and [tex]H'(x,y) = (6,6)[/tex].

Using the permutation formula, it is found that 5040 passwords are possible.

The order is important, as 1234 is a different password than 2134, for example, hence the permutation formula is used to solve this question.

What is the permutation formula?

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this problem, 4 digits are taken from a set of 10, hence:

[tex]P_{(10,4)} = \frac{10!}{6!} = 5040[/tex]

5040 passwords are possible.

Step-by-step explanation:

If 3 feet is 0.9144 and you have 12ft, you first need to divide the 12 by 3 and you get 4. Now that you have the scale factor you multiply the 0.9144 by 4 and you get 3.6576 but they want it to the nearest hundredth (second number after the decimal point) so the answer will be 3.66m

2.2     Factoring  x6 - x3 - 1

The first term is,  x6  its coefficient is  1 .

The middle term is,  -x3  its coefficient is  -1 .

The last term, "the constant", is  -1

Step-1 : Multiply the coefficient of the first term by the constant   1 • -1 = -1

Step-2 : Find two factors of  -1  whose sum equals the coefficient of the middle term, which is   -1 .

The inner circumference of a hollow cylindrical pipe is 4.5 metres and outer circumference is 4.6 metres. Find the cost of painting both its inner and outer sides at the rate of 20 per metre square, if it is 8 metres tall.

Answers

Answer:

[tex]\$527.2[/tex]

Step-by-step explanation:

[tex]r_i[/tex] = Inner radius

Inner circumference = 4.5 m

[tex]2\pi r_i=4.5\\\Rightarrow r_i=\dfrac{4.5}{2\pi}\\\Rightarrow r_i=\dfrac{2.25}{\pi}[/tex]

[tex]r_o[/tex] = Outer radius

Outer circumference = 4.6 m

[tex]2\pi r_o=4.6\\\Rightarrow r_o=\dfrac{4.6}{2\pi}\\\Rightarrow r_o=\dfrac{2.3}{\pi}[/tex]

h = Height of cylindrical pipe = 8 m

Total surface area to be painted

[tex]s=\pi r_i^2h+\pi r_o^2h\\\Rightarrow s=\pi h(r_i^2+r_o^2)\\\Rightarrow s=\pi\times 8((\dfrac{2.25}{\pi})^2+(\dfrac{2.3}{\pi})^2)\\\Rightarrow s=26.36\ \text{m}^2[/tex]

Cost of painting 1 square meter is 20

Cost of painting the inner and outer surfaces is [tex]20\times 26.36=\$527.2[/tex]

The total cost painting the surfaces is [tex]\$527.2[/tex].

what is 9 ounces equal to in pounds? please answer in fractions:)

Answers

Answer:

9/16

Step-by-step explanation:

First, note that 10000 multiplied by .5625 will get rid of the decimal point. Therefore, make a fraction where the numerator is .5625 times 10000 and denominator is 10000 like this:

   

.5625 x 10000

 

   

10000

Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:

   

5625 /10000

The greatest common factor of 5625 and 10000 is 625, which means you can divide the numerator and denominator by 625 and keep the same value:

   

5625 ÷ 625 /10000 ÷ 625

And when calculating the numerator and denominator in our fraction above, we get .5625 as a fraction in the simplest form possible:

 .5625  =  

   

9 /16

 

   

this would be the answer 0.5625
