PLEASE HELP The Vertex Of This Parabola Is At (-2, 1). Which Of The Following Could Be Itsequation?

Answers

Answer 1

Answer:

A. [tex]x = 4\cdot (y-1)^{2}-2[/tex]

Step-by-step explanation:

From the image attached below statement we understand that a parabola with a horizontal axis of symmetry and whose vertex is centered at [tex]V(x,y) = (h,k)[/tex] is defined by the following expression:

[tex]x-h = C\cdot (y-k)^{2}[/tex] (1)

Where [tex]C[/tex] is the parabola factor, when [tex]C > 0[/tex], the parabola is oriented in the +x direction, otherwise is oriented in the -x direction. Hence, we may conclude that equation of the parabola is of the form:

[tex]x+2 = C\cdot (y-1)^{2}[/tex]

[tex]x = C\cdot (y-1)^{2}-2[/tex], where [tex]C > 0[/tex]

The correct answer is A.

A

Write the equation of an ellipse with the following characteristics: center =(1,-3) vertices=(-6,-3),(8,-3)
Foci =(-4.7,-3),(6.7,-3)

Answers

Answer:

(x-1)²/49 + (y+3)²/16.51 = 1

Step-by-step explanation:

vertex (8,-3)     Foci (6.7,-3)   center (h,k) = (1,-3) , major axis parallel to x axis

a  is the distance of the vertex from the center, and c   is the distance of the foci from the center. b is semi-minor axis

b² = a² - c²         Ellipse equation: (x-h)²/a² + (y-k)²/b² = 1

a = 8-1 = 7         c = 6.7 - 1 = 5.7

b² = 7² - 5.7² = 16.51

Ellipse equation:  (x-1)²/49 + (y- -3)²/16.51 = 1  i.e. (x-1)²/49 + (y+3)²/16.51 = 1

Evaluate the expression |2x-5| for x = -3 and for x = 3

Absolute value = positive

A small artichoke contains about 9 milligrams of vitamin C. It also contains about 15​% of the recommended amount of vitamin C an average adult should get each day. About how many artichokes would an average adult have to eat in a day to get the necessary amount of vitamin​ C.

Answers

Answer:

7 Artichokes

Step-by-step explanation:

To figure this out, we need to find out how much Vitamin C an average adult needs. We set up a proportion.

[tex]\frac{9}{15} = \frac{x}{100}[/tex]

[tex]15x=900[/tex]

[tex]x=60[/tex]

Now, since each artichoke is worth 9 milligrams, we divide 60 by 9.

[tex]60/9=6.66666...[/tex]

So, to get the necessary amount of Vitamin C, we round up to 7.

Monica had a savings account that paid her an interest rate of 4%. After she had this account for 12 years, she had received $192 in interest. How much money had she put into the account at the beginning of the 12 years?

Answers

Answer:

Money she put in her account = $400

Step-by-step explanation:

As, to find the interest the formula is PTR/100 = I

Where P = Principcal

And T = time (in years)

And R = rate

And I = interest

So here p is not present we need to find it

R = 4%

And T = 12 years

And I = $192

= p x 4 x 12 /100 = 192

P x 4 x 12 = 19200

P x 48 = 19200

P = 19200/48

P = 400

So Principcal = $400
