Answer:
(-5, 0) and (5, 0)
Step-by-step explanation:
This equation fits the form for a hyperbola with x-intercepts. The standard form for such an equation is

To get the equation in the question into this standard form, divide each term by 400.

To find the x-intercepts, make <em>y</em> = 0.

The vertices are located at the points (-5, 0) and (5, 0).
<em>Note: </em>There are no <em>y</em>-intercepts; making <em>x</em> = 0 produces no real solutions for <em>y</em>.
Answer:
a)
g(3.5), g(26.92)
or
g(3.5)=3.5^2, g(26.92)=26.92^2
Answer:
Jenna needs 2 yards of ribbon to wrap 4 boxes.
Step-by-step explanation:
First, we can find how many inches of ribbon she needs.
18*4=72
She needs 72 inches of ribbon for 4 yards.
There are 36 inches in a yard.
72/36=2
Jenna needs 2 yards of ribbon to wrap 4 boxes.
Volume of a ball = (4/3)πr³
When r = 18cm, V = (4/3)×3.14×18³ =24416.64 cm³
When r = 12cm, V = (4/3)×3.14×12³ =7234.56 cm³
Difference = 24416.64 - 7234.56 = 17182.08 cm³
the volume of air in the larger ball is <span>17182.08 cm³ greater than smaller ball </span>
