Write An Equation For Each Quadratic Function Whose Graph Is Shown

Answers

Answer 1

Answer:

9. y=5[tex]x^{2}[/tex]

10. y=2/3[tex]x^{2}[/tex]

11. y=1/10[tex]x^{2}[/tex]

12. y=-1/4[tex]x^{2}[/tex]

Step-by-step explanation:

9. Use vertex form (y=a(x-h)^2+k) and insert the vertex (0,0) as (h, k).

y=a(x-0)^2 +0

Substitute the x and y values for the given point on the graph, (-1, 5)

5=a(-1-0)^2+0

Solve for a.

5=a(-1)^2

5=a

Substitute a in vertex form and solve for general form (ax^2 +bx+c)

y=5[tex]x^{2}[/tex]

Use this method to find the rest of the equations.

Please help me as soon as possible, it would be great if you gave me an explanation!

Answers

For number 20:

Because a triangle is 180 degrees, we will equal all the angles we know to that. So, this is how we will write our equation:

Solve for x:

60 + x + 20 + 3x = 180

4x = 100

x = 20

Using 75, you can find the angle measure by plugging 75 where x is present in the angle measures. For example:

x = 20,

20 + 20 = 40

3(20) = 60

-

For number 21:

The shape shown is basically two triangles, so 180 x 2 is 360. Again, same procedure. Add all known angle measures and make an equation where they all equal 360.

Solve for x:

x-5+x+35+1.4x+x=360

x = 75

By isolating x, you should get an answer of 75. Now, plug that into each of the equations:

x = 75

75 + 35 = 110

75 - 5 = 70

1.4(75) = 105

Step-by-step explanation:

If LP = 15 and PR = 9, find LR. Explain. LR = 24 because 15 + 9 = 24 according to the addition property of equality. LR = 6 because LR + LP = PR according to the Segment Addition Postulate, and 6 + 9 = 15 using substitution. LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution. LR = 6 because 15 − 9 = 6 according to the subtraction property of equality.

Answers

Step-by-step explanation:

Given,

LP = 15, PR = 9

Point P lies on the line segment PR. It would mean that,

LP + PR = LR

⇒LR = 15 + 9

⇒ LR = 24

Hence, "LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution" is the correct option.

The students at Norton School were asked to name their favorite type of pet. Of the 430ilar results, about students surveyed, 258 said that their favorite type of pet was a dog. Suppose that only 100 students were surveyed, with similar results about how many students would say that a dog is their favorite types of pet?

Answers

Answer: 60

Step-by-step explanation:

From the question, we are informed that 430 students were surveyed and 258 said that their favorite type of pet was a dog. The fraction/decimal of those that chose dog as their favorite pet will be:

= 258/430

= 3/5

= 0.6

Suppose that only 100 students were surveyed, the number of students that would say that a dog is their favorite types of pet will be:

= 0.6 × 100

= 60

the cost (in dollars)of making u cell phones is represented by C=20u+61. How many cell phones are made when the cost is $481

Answers

Answer:

U=21

Step-by-step explanation:

What they are asking for is U. They tell you that the cost is 481 so the C is 481

481=20u+61

You minus 61 from 481 which is 420.

420=20u

Then you divide 20 from 420 and you will get 21.

Answers

Going from f(x) = x to g(x) = f(x-6) = x-6 will move the graph 6 units to the right.

Effectively replacing x with x-6 shifts the xy axis 6 units to the left, giving the illusion the function curve shifts 6 units to the right.

Answer: shifts 6 units to the right.

Caitlyn spends $17 at the store. She buys a mop for $5 and 3 bottles of floor cleaner. If x represents the cost of each bottle of cleaner, the equation that can be used to find the value of x is 3 x + 5 = 17. Which shows the first step that should be taken to verify that $4 is the solution to the equation?
3 (4) minus 5 = 17
3 (4) = 17 + 4
3 (4) + 5 = 17 + 5
3 (4) + 5 = 17

Answers

Answer:

3(4) + 5 = 17

Step-by-step explanation:

Caitlyn spends $17. Buys mop for $5 and 3 floor cleaner. x=cleaner

3x + 5 = 17

3(4) + 5 = 17

12 + 5 = 17

17 = 17 (true)

It would have to be the last one 3(4)+5=17

Let us hold what we have got." Indeed, there was some disposition to take this stand. Some of the stockholders were seriously alarmed when our production reached one hundred cars a day. They wanted to do something to stop me from ruining the company, and when I replied to the effect that one hundred cars a day was only a trifle and that I hoped before long to make a thousand a day, they were inexpressibly shocked and I understand seriously contemplated court action. . . . The temptation to stop and hang on to what one has is quite natural. I can entirely sympathize with the desire to quit a life of activity and retire to a life of ease. I have never felt the urge myself but I can comprehend what it is although I think that a man who retires ought entirely to get out of a business. There is a disposition to retire and retain control.
