write a quadratic function that has a graph that contains the following points, (-2, 0), (4, -12), (5,0).

ankoles [38]

Answer:

f(x) = 2x^2 - 6x - 20.

Step-by-step explanation:

(-2, 0) and (5, 0) are 2 zeroes of the function so we can write the function as

f(x) = a(x + 2)(x - 5) where a is a constant.

Now as (4, -12) is a point on the graph:

-12 = a(4 + 2)(4 - 5)

-12 = a * 6 * -1

-6a = -12

a = 2.

So f(x) = 2(x + 2)(x - 5)

f(x) = 2x^2 - 6x - 20.

The center of a circle is at (−5, 2) and its radius is 7. What is the equation of the circle?

Rainbow [258]

Answer:

(X+5)^2 + (Y-2)^2 =49

Step-by-step explanation:

Equation of the circle

(X-a)^2+(Y-b)^2= r^2

lara [203]

She needs to purchase a cover to protect the hot tub of an area of 38.5 square feet.

<h3>What is a circle?</h3>

It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

Claire has a hot tub with a diameter of 7 feet. She wants to purchase a cover to protect the hot tub.

The area of the circle is given by

$\rm Area = \dfrac{\pi}{4}d^2$

We have d = 7 ft, then the area of the circle will be

$\rm Area = \dfrac{3.14}{4}*7^2\\\\Area = 38.5 \ ft^2$

More about the circle link is given below.

Find the Range of the graph

givi [52]

Answer: Range is a set/group of y-value points of a function. If/when the dot is filled in, the number is included in the set. This is signified by a bracket []. If/when the dot is not filled in, the number is not included in the set. This is signified by a parentheses (). The range of this graph is [4,-9).
