Increase the to y-values of their directrixes, and the equations are

y = 2*x^2 + 15x + 18

y = -2*x^2 + 4x + 8

y = -x^2 + 3x + 8

Hope it helps.

With the form f(x+a) the vertex of the parabola will be shifted to left with a>0 and to the right with a<0. The larger the magnitude of a the more shift. So we can simply sort by the value a in descending order:

f(x+3)-->f(x+2)-->f(x)-->f(x-1/2)-->f(x-4)-->f(x-7)

<h2>Answer:</h2>

Part A

<u>The area is 20x5+16x4−26x3+22x2+32x−24 sqaure units</u>

Part B

<u>Yes the answer is polynomial</u>

Part C

<u>The degree is 5</u>

<h2>Step-by-step explanation:</h2><h3>Part A</h3>

The solution is given in the attached figure

In mathematics, a polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. So the answer is a polynomial in our case.

The degree of a polynomial is the highest degree of its individual terms with non-zero coefficients. The degree of an expression is the sum of the exponents of the variables that appear in the polynomial, and thus is a non-negative integer. In our case the degree of the polynomial is 5.

Triangle RST has vertices located at R (2,3), S (4,4), and T (5,0).

Mazyrski [523]

The slope of RS, RT, and ST are 1/2, -1 and -4 respectively

<h3>Triangle and slopes</h3>

Given the folllowing coordinates R (2,3), S (4,4), and T (5,0) os triangle RST

The formula for calculating the distance is expressed as:

D = √(x2-x1)²+(y2-y1)²

For length RS:

D = √(4-3)²+(4-2)²

RS = √1+4
RS= √5

For length RS:

RT = √(0-3)²+(5-2)²

RT = √9+9
RT= 3√2

For length ST:

D = √(0-4)²+(5-4)²

ST = √16+1
ST= √17

Since all the sides are different, the triangle is a scalene triangle.

For the slope of the sides

For the side RS;

Slope = 4-3/4-2

Slope of RS = 1/2

For the side RT:

Slope = 0-3/5-2

Slope of RT = -3/3 = -1

For the side ST

Slope of ST = 0-4/5-4
Slope of ST = -4/1 = -4

Hence the slope of RS, RT, and ST are 1/2, -1 and -4 respectively

Find P(A or B), if events A and B are overlapping.

BlackZzzverrR [31]

The answer is 7/9

P(A or B) = P(A) + P(B) - P(A and B)
P(A) = 11/18
P(B) = 5/18
<span>p(A and B) = 2/18
</span>P(A or B) = 11/18 + 5/18 - 2/18 = (11 + 5 - 2)/18 = 14/18 = 7/9

Marylou is blowing up a beach ball. The package says that the ball has a diameter of 18 inches. What is the volume of the beach

Arturiano [62]

<span>Use the formula below to find the volume of the beach ball.
Remember that the radius is one-half of the diameter.
V=3/4 pi r^3 =4/3(3.14)(9 in)^3 =3,052.08
Therefore, the beach ball has a volume of 3,052.08 cubic inches when it is completely full.
