Answer:

y=-7(x+1)^2 +8

Step-by-step explanation:

Vertex as shown in vertex form, and solve for the coefficient by plugging in the point.

y=-9(x+1)^2+8

start with the vertex form of a parabola:

y=a(x-h)^2+k , "h" and "k" are the vertex coordinates, and "a" is the leading coefficient.

1. plug in the vertex coordinates

y=a(x+1)^2+8

2. to find "a", plug in the point coordinates in the function from step 1 for x and y

-1=a(-2+1)^2+8

when you solve this equation, you will find that a=-9

3. substitute "a" value in the equation from step 1

The difference between consecutive integral squares must be greater than 1000. (x+1)^2-x^2>=1000, so x>=999/2 implies x>=500. x=500 does not work, so x>500. Let n=x-500. The sum of the square of n and a number a little over 1000 must result in a new perfect square. By inspection, n^2 should end in a number close to but less than 1000 such that there exists 1000N within the difference of the two squares. Examine when n^2=1000. Then, n=10sqrt(10). One example way to estimate sqrt(10) follows.

3^2=9, so 10=(x+3)^2=x^2+6x+9. x^2 is small, so 10=6x+9. x=1/6 implies sqrt(10)\approx 19/6. This is 3.16.

Then, n approx 31.6. n^2<1000, so n could be 31. Add 500 to get the first square and 501 to get the second. Then, the two integral squares are 531^2 and 532^2. Checking, 531^2=281961 and 532^2=283024. 282,000 straddles the two squares, which have a difference of 1063. The difference has been minimized, so N is minimized N=282000 implies 282

For pictures of two rectangular pens, see the attachment.

Area of rectangle = length × width

A = x × y

1200 = xy

     y = 1200/x

The entire length of the fence

P = 3x + 4y

P = 3x + 4800x⁻¹

Find dimentions will minimize the length of fencing, if P' = 0.

P = 3x + 4800x⁻¹

P' = 3 - 1 × 4800x⁻¹⁻¹

0 = 3 - 4800x⁻²

4800x⁻² = 3

4800/x² = 3

4800 = 3x²

According to the question,

A norman window has the shape of a rectangle surmounted by a semicircle.

Let The width of rectangle be x and height be y

It is given that  the diameter of the semicircle is equal to the width of the rectangle

Therefore , Diameter of circle = x

Radius = x/2

Perimeter of window  = 32 = Perimeter of rectangle + Perimeter of semi-circle

=> 32 = Width + 2height + πr

=> x + 2y + πx/2 = 32

=> 2x + 4y +  πx = 64

Solving for y,

=> 4y = 64 - 2x - πx

=> y = 64  - 2x - πx/ 4 ----------(1)

Area of the window = Area of rectangle + area of semi-circle

=> A = Width × hiegth +  πx²/8

=> A = xy + πx²/8

Substituting the value of y from equation (1)

=> A =  x (  64  - 2x - πx/ 4  ) + πx²/8

[tex]A = x ( \frac{64 - 2x -\pi x}{ 4} ) + \frac{\pi x^2}{8}\\A = ( \frac{ 64x - x^2 ( 2 + \pi)}{4 } ) + \frac{\pi x^2}{8}[/tex]

As there is sufficient evidence to conclude that the population mean weight is at least 16 ounces.

What is standard deviation ?

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Think about the following data: 2, 1, 3, 2, 4. The average and the total square of the observations' departures from the mean will be 2.4 and 5.2, respectively. This means that (5.2/5) = 1.01 will be the standard deviation.

The following null and alternative hypotheses need to be tested

H0 :  µ  = 16

Hα :  µ  < 16

Since both AB  and BA exist, where B is also a n×n square matrix.

On using the rank–nullity theorem, we get

nullity of a matrix be n minus the rank of the matrix.

So let  U  be a matrix whose columns are a basis for the nullspace of  AB, so that  ABU = 0.

Pre-multiplying both sides by  A−1 , we obtain  BU=0,

As B and AB have the same rank.

Similarly, let  V  be a matrix whose columns are a basis for the null space of  ATBT, so that  ATBTV=0 .

Pre-multiplying both sides by (A−1)T , we get

Answer:

  a. $461.67

  b. $12771.73

Step-by-step explanation:

You want to know the monthly payment and total amount paid for a car that costs $12500 when $4000 is the down payment and the interest is 3.8% for 19 months.

The formula for the monthly payment is ...

  A = P(r/12)/(1 -(1 +r/12)^-n)

where P is the amount borrowed at interest rate r compounded monthly for n months.

Here, the down payment of $4000 reduces the loan amount to ...

  $12500 -4000 = 8500

So, the monthly payment is ...

  A = 8500(0.038/12)/(1 -(1 +0.038/12)^-19) ≈ 461.67

Matteo needs to pay $461.67 each month.

The total Matteo pays for the car will be the sum of the down payment and the 19 monthly payments:

  total = $4000 +19×461.67 = $12771.73

Matteo will end up paying $12771.73 for his car.

Step-by-step explanation:

The object is undergoing uniform circular motion. The radius of the circular path is equal to 0.50 meters. The centripetal force, F, acting on the object can be calculated using the equation F= mv^2/r in hporizontal circular path

m is the mass of the object, v is the velocity of the object and r is the radius of the circular path.

F = (1.0 kg) (5.0 m/s)^2 / 0.50 m

F = 50.0 kg m/s^2

The object is undergoing uniform circular motion, which means it is moving at a constant speed in a circular path with its center at point O. The radius of the circular path is equal to 0.50 meters. The force acting on the object is known as the centripetal force, and can be calculated by using the equation F= mv^2/r. This equation requires the mass of the object (m), its velocity (v), and the radius of the circular path (r). In this case, the mass is 1.0 kg, the velocity is 5.0 m/s, and the radius is 0.50 m. Plugging these values into the equation gives the centripetal force acting on the object as 50.0 kg m/s^2.

When the data set is extremely small, the algorithm might fail to detect the inherent clusters in the data set. When the data set has a high degree of overlap between clusters, the algorithm might generate too many clusters and fail to capture the underlying structure of the data.

Partitional clustering algorithms can automatically determine the number of clusters, which is often perceived as an advantage. However, this is not always the case. For example, when the data set is small the algorithm might be unable to detect the true clusters in the data set. Additionally, when the data set has high levels of overlap between clusters, the algorithm might generate too many clusters and fail to recognize the underlying structure of the data. In these cases, the automatic determination of the number of clusters can be disadvantageous as it fails to capture the true structure of the data.
