Yankees. If he shuffles the cards what is the probability that the first card he picks is a Tigers
player?

Answer:

Step-by-step explanation:

Definition

               a fixed point (the focus ), and

               a fixed straight line (the directrix )

From the graph we can see that this is indeed so. We can even calculate the parabola equation from the given graph but since that is not required, I am not illustrating the steps here to do that

(Note on last question: If you exclude these two points then y > 0 between x=2 and x=6.Specifically it is 0 at x =2 and x=6 and > 0. So if you include these two points then y ≥ 0.  I have taken it as excluding the two points, x = 2 and x =6)

Answer:

Step-by-step explanation:

Rise over run is the slope, m

m=2/5

a)  the slope is 2/5 = .4 which is below the boundary guideline.  So no this is not with in carpenter's guidelines

b) the image below show a line with slope 2/5 but with intercept 3

c) the stairs can be draw on the line with rise 2 run 5   from the line.  see image

d)equation is in image

2.

a) count the squares

horizontal distance =3

vertical distance =3

b)  slope is vertical distance over horizontal distance  so m= 3/3 =1

Answer:

20

Step-by-step explanation:

The didderence between -3 and 2 is 5 so to account for those two sides we have 5·2=10.

The difference between 9 and 4 is also 5 so to account fo the other two sides we also have 5·2=10

Adding these together we have 10+10=20.

Answer:

B, C, D are the answers

Step-by-step explanation:

Cost of the item you multiply with amount

The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.

With that being said, here is the order of the numbers from smallest to largest:

4.38

4.5

4.6

4.9

Answer:

Here are the numbers ordered from closest to zero to farthest from zero:

4.38 (closest to zero)

4.5

-4.6

-4.9 (farthest from zero)

Step-by-step explanation:

Answer:

\(f(x)=9(x+\frac{1}{6})^2-\frac{21}{4}\)

Step-by-step explanation:

So, we need to find the equation of a parabolic function that goes through the points (-3,67) and (-1,1) and has a stretch factor of 9.

In other words, we want to find a quadratic with a vertical stretch of 9 that goes through the points (-3,67) and (-1,1).

To do so, we first need to write some equations. Let's use the vertex form of the quadratic equation. The vertex form is:

\(f(x)=a(x-h)^2+k\)

Where a is the leading coefficient and (h,k) is the vertex.

Since a is the leading coefficient, it's also our stretch factor. Thus, let a equal 9.

Also, we have two points. We can interpret them as functions. In other words, (-3,67) means that f(-3) equals 67 and (-1,1) means that f(-1) equals 1. Write the two equations:

\(f(x)=a(x-h)^2+k\\f(-3)=67=9((-3)-h)^2+k\)

And:

\(f(x)=a(x-h)^2+k\\f(-1)=1=9((-1)-h)^2+k\)

Now, we essentially have a system of equations. Thus, to find the original equation, we just need to solve for the vertex. To do so, first isolate the k term in the second equation:

\(1=9(-1-h)^2+k\\k=1-9(-1-h)^2\)

Now, substitute this value to the first equation:

\(67=9(-3-h)^2+k\\67=9(-3-h)^2+(1-9(-1-h)^2)\)

And now, we just have to simplify.

First, from each of the square, factor out a negative 1:

\(67=9((-1)(h+3))^2+(1-9(((-1)(h+1))^2)\)

Power of a product property:

\(67=9((-1)^2(h+3)^2)+(1-9((-1)^2(h+1)^2))\)

The square of -1 is positive 1. Thus, we can ignore them:

\(67=9(h+3)^2+(1-9(h+1)^2)\)

Square them. Use the trinomial pattern:

\(67=9(h^2+6h+9)+(1-9(h^2+2h+1))\)

Distribute:

\(67=(9h^2+54h+81)+(1-9h^2-18h-9)\)

Combine like terms:

\(67=(9h^2-9h^2)+(54h-18h)+(81+1-9)\)

The first set cancels. Simplify the second and third:

\(67=36h+73\)

Subtract 73 from both sides. The right cancels:

\(67-73=36h+73-73\\36h=-6\)

Divide both sides by 36:

\((36h)/36=(-6)/36\\h=-1/6\)

Therefore, h is -1/6.

Now, plug this back into the equation we isolated to solve for k:

\(k=1-9(-1-h)^2\)

First, remove the negative by simplifying:

\(k=1-9((-1)(h+1))^2\\k=1-9((-1)^2(h+1)^2)\\k=1-9(h+1)^2\)

Plug in -1/6 for h:

\(k=1-9(-\frac{1}{6}+1)^2\)

Add. Make 1 into 6/6:

\(k=1-9(-\frac{1}{6}+\frac{6}{6})^2\\ k=1-9(\frac{5}{6})^2\)

Square:

\(k=1-9(\frac{25}{36})\)

Multiply. Note that 36 is 9 times 4:

\(k=1-9(\frac{25}{9\cdot4})\\ k=1-\frac{25}{4}\)

Convert 1 into 4/4 and subtract:

\(k=\frac{4}{4}-\frac{25}{4}\\ k=-\frac{21}{4}\)

So, the vertex is (-1/6, -21/4).

Now, plug everything back into the very original equation with 9 as a:

\(f(x)=a(x-h)^2+k\\f(x)=9(x+\frac{1}{6})^2-\frac{21}{4}\)

And this is our answer :)
