We can use the vertex form
$y = a {(x - h)}^{2} + k$
to find the equation of the graph. We know that a is the coefficient, and since the graph opens upwards and is slightly stretched vertically, we know that a is 1/3. On the graph, we see that the vertex of the parabola is at (0,-1). Therefore, h is 0 and k is -1.
Our vertex form equation is
$y = \frac{1}{3} {x}^{2} - 1$
Which is D

Find the center of the circle whose equation is x² + y² = 4.

Varvara68 [4.7K]

Answer:

The center of circle is $(0,0)$

Step-by-step explanation:

We need to find the center of the circle of the equation $x^{2}+y^{2}=4$

Since, the general equation of circle is $(x-h)^{2}+(y-k)^{2} = r^{2}$

Where (h,k) is center of circle and r is radius.

Re-write the circle equation is $x^{2}+y^{2}=4$ as,

$x^{2}+y^{2}=2^{2}$

Compare $x^{2}+y^{2}=2^{2}$ with $(x-h)^{2}+(y-k)^{2} = r^{2}$

so, $(x-0)^{2}+(y-0)^{2} = 2^{2}$

Hence, the center of circle is $(0,0)$

Avicenna, a major insurance company, offers five-year life insurance policies to 65-year-olds. If the holder of one of these pol

ki77a [65]

Answer:

Avicenna can expect to lose money from offering these policies. In the long run, they should expect to lose ___33__ dollars on each policy sold

Step-by-step explanation:

Given :

The amount the company Avicenna must pay to the shareholder if the person die before 70 years = $ 26,500

The value of each policy = $497

It is given that there is a 2% chance that people will die before 70 years and 98% chance that people will live till the age 70.

The expected policy to be sold= policy nominal + chances of death

= 497 + [98% (no pay) + 2% (pay)]

= 497 + [98%(0) + 2%(-26500)]

(The negative sign shows that money goes out of the company)

= 497 - 2% (26500)

= 497 - 530

=33

Therefore the company loses 33 dollar on each policy sold in the long run.

Step-by-step explanation:

If you find where the line crosses the y-axis, and count to the next official and visible vertex, you will get 3 up or down, over 1 left or right. It's called rise over run. And as the line is drawn from the left to right side, it's a negative line.
