Find the x-intercepts of the parabola with vertex (1, -9) and y intercept at (0, -6).
weqwewe [10]
  • Vertex Form: y = a(x - h)^2 + k, with (h,k) as the vertex.

So firstly, plug the vertex into the vertex form: y=a(x-1)^2-9

Next, we first need to solve for a. Plug (0,-6) into the equation to solve for a as such:

-6=a(0-1)^2-9\\-6=a(-1)^2-9\\-6=a-9\\3=a

<u>Now we know that our equation is y = 3(x - 1)^2 - 9.</u>

Now to solve for the zeros (x-intercepts). Set y to 0 and add 9 to both sides of the equation: 9=3(x-1)^2

Next, divide both sides by 3: 3=(x-1)^2

Next, square root both sides: \pm\sqrt{3}=x-1

Next, add 1 to both sides: 1\pm\sqrt{3}=x\\2.73,-0.73=x

<u>Your x-intercepts are (-0.73,0) and (2.73,0), or B.</u>

A tetrahedron is a triangular pyramid whose four faces are identical equilateral triangles. The total lateral surface area is 93
Westkost [7]

Answer:

SA = 124 cm²

Step-by-step explanation:

The lateral surface area is the area of all sides besides that base, so 93 cm² is the sum of 3 sides of the tetrahedron.  

93/3 = 31 cm² per side, there are 4 sides, so 31(4) = 123 cm² is the total surface area

What is the best approximation for the area of a circle with a diameter of 19 meters?
FromTheMoon [43]
A = \pi r^{2} is the equation used for determining area from radius.  We're given diameter, so to get the radius simply divide by 2. 19/2 = 9.5.

A = (3.14)(9.5)^{2}, when solved, equals 283.385 m^(2).  After rounding to the nearest tenth, we get 283.4 m^{2}
