Answer:

x = 0

Step-by-step explanation:

A line that has undefined slope is a vertical line. A vertical line has an equation in the form "x = anumber"

In the given information, (0,5), x is 0 and y is 5. What we need is the information on x.

x is 0.

x = 0 is the equation of the line.

Answer:

x=0.

Step-by-step explanation:

undefined slope is a vertical line. if it passes through (0,5) it means its on the y line

To determine which is the best buy, we need to first find the unit price of each

8 oz $2.40

Unit price

$2.40/8 = $0.3

1 oz = $0.3

24 oz $6.48

Unit price

$6.48/24 =$0.27

1 oz = $0.27

64 oz $14.08

Unit price

$14.08/64 =$0.22

From the above the best best buy is the one with the lowest price which is $0.22

The best buy is;

64 oz $14.08

and the unit rate is $0.22 per oz

Answer:

Equation of the parabola:

The height of the arch 18 meters from the center is 6.75m

Explanation:

The arch feet are 72m apart and the origin half way between them. This means that the axis of symmetry (or the x.coordinate of the vertex) is x = 0

Since it's an arch, the parabola is concave down, with it's maximum at the vertex, y = 9. This means that the vertex is at (0, 9). Also, we can see that the y-intercept is y = 9

Finally, we know the two roots of the parabola: x = -36 and x = 36. This is because the points x = -36 and x = 36 are 72m apart, with the center at the original, as the problem says. SInce x = 36 is a root, this means that at that point the y value is 0.

With all this, we can try to find the general form of a parabola. The general form is:

c is the y-intercept. We know that c = 9

We can find the value of b, because we know the coordinates of the vertex. The x-coordinate of the vertex is:

SInce the x-coordinate of the vertex is x = 0

If we solve:

So far we have:

Finally, to find a, we can use the point (36, 0) (one of the roots)

And solve:

Thus, the equation of the arch is:

Evaluating this equation for x = 18, we can find the height of the arch:

Answer:

x=5

Step-by-step explanation:

If the slope is undefined, it is a vertical line. Since the slope-intercept equation is y=mx+b, but the slope is undefined, the equation would have to be the x coordinate, because that is the unchanging variable in a vertical line. So, the answer is x=5.

Answer:

Step-by-step explanation:

To find k, we use

∫∞−∞∫∞−∞fXY(x,y)dxdy=1.

Thus, we have

1=∫∞−∞∫∞−∞fXY(x,y)dxdy=∫10∫10x+cy2dxdy=∫10[12x2+cy2x]x=1x=0dy=∫1012+cy2dy=[12y+13cy3]y=1y=0=12+13c.

Therefore, we obtain c=32.

To find P(0≤X≤12,0≤Y≤12), we can write

P((X,Y)∈A)=∬AfXY(x,y)dxdy,for A={(x,y)|0≤x,y≤1}.

Thus,

P(0≤X≤12,0≤Y≤12)=∫120∫120(x+32y2)dxdy=∫120[12x2+32y2x]120dy=∫120(18+34y2)dy=332.

We can find marginal PDFs of X and Y from their joint PDF. This is exactly analogous to what we saw in the discrete case. In particular, by integrating over all y's, we obtain fX(x). We have

Marginal PDFs

fX(x)=∫∞−∞fXY(x,y)dy, for all x,fY(y)=∫∞−∞fXY(x,y)dx, for all y.

Example

In Example 5.15 find the marginal PDFs fX(x) and fY(y).

The absolute value function as piecewise function of y = -3(x + 24)/4 and y = 3(x - 38)/4

The absolute value function is commonly understood as a function providing the distance the number is from zero on a number line.

y = 3/4|x-6|-8

y = 3/4(-(x-6))-8

y= 3/4( -x + 6) -8

y = 3(-x + 6 - 32)/4

4y = -3x - 24

y = -3(x + 24)/4

For another function of y

y = 3/4|x-6|-8

y= 3/4( x - 6) -8

y = 3(x - 6 - 32)/4

4y = 3(x - 38)

1. The simple interest rate is 80%

2. The interest earned on the account after 10 years is $75

Simple interest can be defined as a mathematical or arithmetic method of calculating the charge of interest on a given loan.

The formula for simple interest is expressed as;

I = PRT/100

Where;

From the information given, we are to determine the interest rate, R

Substitute the values into the formula, we have;

320 = 200 × R × 2/100

Now, cross multiply, we have;

320(100) = 400R

Find the product of the values

400R = 32000

Divide both sides by the coefficient of the interest rate, we get

R = 32000/400

Find the quotient

R = 80%

If the interest for 2 years is $15

Then in 10 years = $x
