Find the equation of the parabola in general form

Answers

Answer:

x^2-4x+3

Step-by-step explanation:

Since the zeroes of the quadratic are 1 and 3, we can set up an equation in factored form:

(x-1)(x-3)

=x^2-4x+3

We can further check that this is the right answer by evaluating it at the vertex:

(2)^2-4*2+3=-1

Since that corresponds to the graph, the answer is x^2-4x+3

Answers

Answer:

The Answer is 16.

Step-by-step explanation:

I took the test. I hope this helped! :)

The remainder when 73,847 is divided by 43 will be 16.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The mathematical expression is,

''73,847 is divided by 43''

Now,

Find the remainder when 73,847 is divided by 43 as;

43 ) 73,847 (1717

    - 43

   --------

      308

    - 301

     -------

          74

          43

Complete Question

The alternative hypothesis is [tex]H_a : p > 0.9[/tex] and it is found the statistic is 1.04 Test the claim with 5% significance level. is the test left right or two tailed and what is the p value

Answer:

    This a right tailed test

  The p-value is   p-value  = 0.14917

Step-by-step explanation:

From the question we are told that

   The alternative hypothesis is [tex]H_a : p > 0.9[/tex]

   The test statistics is  [tex]z = 1.04[/tex]

    The level of significance is  [tex]\alpha = 0.05[/tex]

Generally this a right tailed test because from the alternative hypothesis p > 0.9 i.e due to the greater than sign signifying that test will be focusing on the right tail of the normal curve

From the z table the area under the normal curve to the right corresponding to 1.04 is  

     P( Z>  1.04 )  = 0.14917

Generally the p-value is mathematically represented as

      p-value  =  P( Z>  1.04 )  = 0.14917

3x-4y+z=-5
6x-4y+z=1
x+y+z=6

Answers

Answer:

first equation and second equation

Step-by-step explanation:

it is more easier because both of them have the same y

Answer:

Use equation (1) and equation(2) and eliminate 4y+z

Step-by-step explanation:

3x-4y+z=-5     ...(1)

6x-4y+z=1        ...(2)

x+y+z=6          ...(3)

First, you find the equation that you can use the elimination method on;

there are multiples of them.

However, I would use equation (1) and equation(2) and eliminate 4y+z :

 3x-4y+z=-5

- 6x-4y+z=1  

         -3x=-6

            x=2

As you can see, both the terms with y and z are eliminated in one step, exposing the variable x.

From here is just my advice:

There are multiple ways for you to answer this question. In math, the process may sometimes not matter if the answer was correct. Nevertheless, you should try finding one way that fits you or makes it easier to solve. I personally think that how I have been trying this helped me later when math got more complicated. (Also, it was fun for me to find another way that I was not taught of)

A picture frame has a perimeter of 62 inches. The difference between the
length and twice the width is 1 inch. What are the length and width of the
frame?

Answers

Answer: each width = 10, each length = 21

Explanation: from the question we know that L=2w + 1 and we also know that a rectangle has the perimeter of 62 when we plug it in the equation we will get 62= 2(2w+1+w) we will multiply the 2 now and we will get 62=4w+2+2w we will combine like terms and we will minus two from both sides ending up with 60=6w we will divide six from both sides and we will get w=10 then we will use l=2w+1 to find the length and it will be 21

Cada semana de los últimos 3 años Lucía ha hecho 120 km en bicicleta y cada mes 100 km corriendo y 15 km nadando. Debe cambiar la bicicleta cada 20.000 km. ¿Tiene que cambiarla ya?

Answers

Answer:

Lucía no tiene que cambiar ya la bicicleta porque ha recorrido 18,720 km.

Step-by-step explanation:

Para determinar la respuesta tienes que encontrar la cantidad de km que Lucía ha hecho en 3 años multiplicando los 120 km que hace a la semana por la cantidad de semanas que hay en 3 años. Para determinar las semanas, tienes que considerar que en 1 año hay 52 semanas:

Semanas=52*3= 156 semanas

120*156=18,720 km

De acuerdo a esto, la respuesta es que Lucía no tiene que cambiar ya la bicicleta porque ha recorrido 18,720 km.

Clear Mark for Review Jamal's lawn is shaped like a square with an area of 224.9 ft. Which measurement is closest to the side length of his lawn in feet?​

Answers

Answer: 15 feets

Step-by-step explanation:

Given that :

Area of square shaped lawn = 224.9 ft²

Measurement closest to side length of the lawn :

Since the length is square shaped ;

Area of square formula = a²; where a = side length of the square

Area = a²

224.9 ft² = a²

Take the square root of both sides

√224.9ft² = √a²

14.996666 ft = a

a = 14.996666 ft

a = 15 ft

Hence, the side length of the lawn is closest to 15 feets

The full title of the book is Tea Leaves: Being a Collectionof Letters and Documents Relating to the Shipment of Tea to the AmericanColonies in the year 1773, by the East India Tea Company.1 Our numbers were between twenty-eight and thirty. . . . I had but afew hours warning of what was intended to be done. We first talked of[setting fire to] the ships, but feared the fire would [spread] to thetown. We then proposed sinking them, but dropped that [idea]through fear that we should alarm the town before we could [finish.]2 We had [noticed] that very few persons remained on board theships. So, we finally concluded that we could take possession of them,and discharge the tea into the harbor without danger or opposition.To prevent discovery, we agreed to [dress] to resemble Indians asmuch as possible. [We smeared] our faces with grease and lamp blackor soot, and should not have known each other except by our voices.Our most intimate friends among the spectators had not the leastknowledge of us.3 At the appointed time, we met in an old building at the head of thewharf. We fell in one after another, as if by accident, so as not to excitesuspicion. We placed a sentry at the head of the wharf, another in themiddle, and one on the bow of each ship as we took possession. Weboarded the ship moored by the wharf1. Our leader, in a very stern andresolute2 manner, ordered the captain and crew to open the hatchways.[He ordered them to] hand us the hoisting tackle and ropes, assuringthem that no harm was intended them. The captain asked what weintended to do. Our leader told him that wewere going to unload the tea, and ordered himand the crew below. They instantly obeyed.4 Some of our number then jumped into thehold, and passed the chests to the tackle. Asthey were hauled on deck, others knockedthem open with axes. Others raised them tothe railing and discharged their contentsoverboard. All who were not needed fordischarging this ship went on board theothers, [tied] them to the wharf, where thesame ceremonies were repeated. We weremerry, in an undertone, at the idea of makingso large a cup of tea for the fishes. [But we]were as still as the nature of the case wouldadmit, using no more words than wereabsolutely necessary. We [moved quickly]from the moment we left our dressing-room.I never worked harder in my life.Boston Tea Party Eyewitness Account:John Andrews1 Inhabitants: people who live in a certain area2 Infernal: awful; related to the mythical world of the dead3 They say the actors were Indians from Narragansett.
