The answer is D. The relative minimum and maximums are where they kind of curve and come back up or down. So that is 64 and -36.

Find the equation of the circle: y-intercepts 4 and –8, contain (–12, –8)

laila [671]

Answer:

(x +6)^2 +(y +2)^2 = 72

Step-by-step explanation:

The given points are vertices of a right triangle. The circle circumscribing that triangle (through all 3 vertices) will have its center at the midpoint of the hypotenuse:

((0, 4) +(-12, -8))/2 = (-6, -2)

The equation of a circle with center (h, k) through point (a, b) is ...

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

For center (-6, -2) and point (0, 4), the equation is ...

(x +6)^2 +(y +2)^2 = (0+6)^2 +(4 +2)^2

(x +6)^2 +(y +2)^2 = 72

The following graph shows a seventh-degree polynomial:

LenaWriter [7]

Part 1: The zeroes are -5 with a multiplicity of 2, -1 with a multiplicity of 1, 4 with a multiplicity of 3, 7 with a multiplicity of 1.

Part 2: The possible factored form of the function is (x + 8)^2(x + 1)(x - 4)^3(x - 7)

A car dealership paid $9,000 for a car. The sticker price is $10,395 for a customer to buy the car. a. What’s the markup in doll

Sladkaya [172]

Answer:

1) To determine how much the change of $9,000 to $10,395, we must subtract 9,000 from 10,395;

10,395 - 9,000 = $1,395 is the change in price (an increase).

Formula to find percentage of change;

Change in price/original amount x 100% (100/100)

Replace those values:

1,935 (change in price/increase) 100
