the vertex of this parabola is at (3,-2). When the x-vaue is 4, the y-value is 3. What is the coefficient of the squared express

bixtya [17]

<h3>Answer: 5</h3>

=========================================================

Explanation:

Vertex form is

y = a(x-h)^2 + k

We are told the vertex is (3,-2), so we know (h,k) = (3,-2)

y = a(x-h)^2 + k will update to y = a(x-3)^2 - 2

--------

Then we also know that (x,y) = (4,3) is a point on the parabola. Plug those x and y values into the equation and solve for 'a'

y = a(x-3)^2 - 2

3 = a(4-3)^2 - 2

3 = a(1)^2 - 2

3 = a - 2

3+2 = a

5 = a

a = 5

This is the coefficient of the x^2 term since the standard form is y = ax^2+bx+c.

United States facing a budget deficit of 1.5 billion, population was 3.9 million how much would each person have to contribute t

Diano4ka-milaya [45]

Answer:

Each person would have to contribute to contribute $385 to pay a 1.5 deficit.

Step-by-step explanation:

To determine:

How much would each person have to contribute to pay a 1.5 deficit if United States facing a budget deficit of 1.5 billion and 3.9 million population?

Fetching Information and Solution Steps:

United States facing a budget deficit of 1.5 billion
Population = 3.9 million

We have to determine how much would each person have to contribute to pay a 1.5 deficit.

Just dividing 1500 millions (1.5 billion) by 3.9 million as:

$\frac{1500}{3.9} =384.6153$

which is rounded to $385.

Therefore, each person would have to contribute to contribute $385 to pay a 1.5 deficit.

What is the surface area of the sphere?

Fantom [35]

Answer:

<em>The surface area of the sphere is 314 mi².</em>

Step-by-step explanation:

According to the given diagram, the diameter of the sphere is 10 mi.

If the radius is $r$ , then diameter $=2r$

So....

$2r=10\\ \\ r=\frac{10}{2}= 5$

<u>Formula for the surface area of a sphere</u>: $A_{S}= 4\pi r^2$

Plugging the value of $r$ into this formula, we will get...

$A_{S}=4\pi(5)^2\\ \\ A_{S}=4\pi(25)\\ \\ A_{S}=4(3.14)(25)\ \ [Using\ \pi=3.14]\\ \\ A_{S}=314$

So, the surface area of the sphere is 314 mi².
