ANSWER

circle

EXPLANATION

The given equation is

{x}^{2}  +  {y}^{2}  = 25

To determine the type of conic, we analyze the coefficient and sign of the quadratic terms.

If the coefficient of the quadratic terms are equal and have the same sign,then the conic is a circle.

If the coefficient of the quadratic terms are equal and have opposite signs,then the conic is a hyperbola.

If the coefficient of the quadratic terms are not equal and have the same sign,then the conic is an ellipse.

Since the coefficients are all 1 and the signs are positive, the given conic is a circle.

A. What is the area of the base? Use complete sentences to explain your reasoning.
Lynna [10]

Answer:

<u>For the first answer (A)</u>

Leah drives 45 miles per hour for 2 hours then 32 miles per hour for 90 minutes . What is her average speed
Citrus2011 [14]

Answer:

 =39.42857143 miles per hour

Step-by-step explanation:

To find the average speed, we need to the total distance and the total time

Distance 1

45 miles for 2 hours

45*2 = 90 miles

Distance 2

90 minutes * 1 hour/60 minutes = 1.5 hours

32 miles * 1.5 hours =48 miles

The total distance = 90+48 = 138 miles

The total time = 2 +1.5 = 3.5 hour

The average speed = total distance/ total time

                                  = 138/3.5

                                  =39.42857143 miles per hour
