The distance between Q(-1, a) and P(3, -2) is 4√5. Find all possible values of a
The numerical values of a in the points Q(-1, a) and P(3, -2) with a distance of 4√5 are 6 and -10.
What is the numerical value of a?The distance formula used in finding the distance between two points is expressed as;
D = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² )
Given the data in the question;
Point Q( -1, a )
x₁ = -1y₁ = aPoint P( 3, -2 )
x₂ = 3y₂ = -2Distance D = 4√5To find the numerical value of a, plug the given coordinates into the distance formula and simplify.
D = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² )
4√5 = √( ( 3 - (-1) )² + ( -2 - a )² )
4√5 = √( ( 3 - (-1) )² + ( -2 - a )² )
Square both sides
( 4√5 )² = ( 3 - (-1) )² + ( -2 - a )²
( 4√5 )² = ( 3 + 1 )² + ( -2 - a )²
( 4√5 )² = ( 4 )² + ( -2 - a )²
80 = 16 + ( -2 - a )²
80 - 16 = ( -2 - a )²
64 = ( -2 - a )²
( -2 - a )² = 64
Expand the parenthesis
( -2 - a )( -2 - a ) = 64
a² + 4a + 4 = 64
a² + 4a + 4 - 64 = 0
a² + 4a - 60 = 0
solve for a
( a - 6 )( a + 10 ) = 0
a - 6 = 0, a + 10 = 0
a = 6, a = -10
Therefore, the values of a are 6 and -10.

Which inequality in vertex form represents the region less than the quadratic function with vertex (-2, 2) and
includes the point (-4, 14) on the boundary?
Answer:
(a) y < 3(x +2)² +2
Step-by-step explanation:
You want to know the inequality representing the region less than the quadratic with vertex (-2, 2) and containing the point (-4, 14).
Vertex formThe vertex form equation for a quadratic with vertex (h, k) and some scale factor 'a' is ...
y = a(x -h)² +k
For the given vertex (-2, 2), the boundary line equation is ...
y = a(x -(-2))² +2 = a(x +2)² +2
Scale factorThe value of 'a' is positive when the curve opens upward.
Here, the point (-4, 14) has a y-value greater than that of the vertex, so we know the curve opens upward (a > 0).
The only reasonable answer choice is ...
y < 3(x +2)² +2

16x + 3 what is x
Answer:
x = 8
Step-by-step explanation:
17x-5 = 16x + 3
Step 1: Subtract 16x from both sides.
17x−5−16x=16x+3−16x
x−5=3
Step 2: Add 5 to both sides.
x−5+5=3+5
x=8
The solution to the equation is x = 8.
To solve the equation 17x - 5 = 16x + 3 and find the value of x, we can follow these steps:
Start by simplifying both sides of the equation by combining like terms. Add 5 to both sides to move the constant term to the right side of the equation:
17x - 5 + 5 = 16x + 3 + 5
17x = 16x + 8
Next, we want to isolate the x term on one side of the equation.
Subtract 16x from both sides:
17x - 16x = 16x - 16x + 8
x = 8
Therefore, the solution to the equation is x = 8.

Write a polynomial P(x) of degree 4 and with zeros 1, 3/2, (which of multiplicity one) and 0 (of multiplicity 2).
Answer
The polynomial is
P(x) = 2x⁴ - 5x³ + 3x²
Explanation
We are told to write a polynomial of degree 4 with zeros (roots)
x = 1
x = (3/2) = 1.5
x = 0
x = 0 (multiplicity of 2 means it appears twice)
So, we can piece together the polynomial
P(x) = (x - 1) (x - 1.5) (x) (x)
We can write this as
P(x) = x² (x - 1) (x - 1.5)
= (x³ - x²) (x - 1.5)
We can multiply through by 2 to turn the 1.5 into a whole number
P(x) = (x³ - x²) (2x - 3)
= x³ (2x - 3) - x² (2x - 3)
= 2x⁴ - 3³ - 2³ + 3x²
= 2x⁴ - 5x³ + 3x²

. let ???? be a discrete random variable that is uniformly distributed over the set of integers in the range [????, ????], where ???? and ???? are integers with ???? < 0 < ????. find the pmf of the random variables max(0,????) and min(0,????).
Filling in the blanks, I assume you're talking about a random variable [tex]X[/tex] distributed uniformly over the integers [tex]a\le x\le b[/tex]. Let both [tex]a,b>0[/tex] so we can write the support of [tex]X[/tex] as the set
[tex]S = \{-a, -a+1, -a+2, \ldots, -1, 0, 1, \ldots, b-2, b-1, b\}[/tex]
Note that [tex]|S| = a+b+1[/tex], so the PMF of [tex]X[/tex] is
[tex]\mathrm{Pr}(X=x) = \begin{cases}\frac1{a+b+1} & \text{if } x\in S \\ 0 & \text{otherwise}\end{cases}[/tex]
Let [tex]Y=\max\{0,X\}[/tex]. Then
[tex]Y = \max\{0,X\} = \begin{cases}0 & \text{if } X\le0 \\ X & \text{if } X>0 \end{cases}[/tex]
which tells us
[tex]\displaystyle \mathrm{Pr}(Y=0) = \mathrm{Pr}(X\le0) = \sum_{x=-a}^0 \mathrm{Pr}(X=x) = \frac{a+1}{a+b+1}[/tex]
and
[tex]\displaystyle \mathrm{Pr}(Y\neq0) = \mathrm{Pr}(X>0) = \sum_{x=1}^b \mathrm{Pr}(X=x) = \frac b{a+b+1}[/tex]
Hence the PMF of [tex]Y[/tex] is
[tex]\mathrm{Pr}(Y=y) = \begin{cases}\frac{a+1}{a+b+1} & \text{if } y=0 \\\\ \frac b{a+b+1} & \text{otherwise}\end{cases}[/tex]
Let [tex]Z=\min\{0,X\}[/tex]. The same reasoning applies, but this time
[tex]Z = \min\{0,X\} = \begin{cases} 0 & \text{if } X \ge 0 \\ X & \text{if } X < 0 \end{cases}[/tex]
Now
[tex]\displaystyle \mathrm{Pr}(Z=0) = \mathrm{Pr}(X\ge0) = \sum_{x=0}^b \mathrm{Pr}(X=x) = \frac{b+1}{a+b+1}[/tex]
and
[tex]\displaystyle \mathrm{Pr}(Z\neq0) = \mathrm{Pr}(X<0) = \sum_{x=-a}^{-1} \mathrm{Pr}(X=x) = \frac a{a+b+1}[/tex]
so that
[tex]\mathrm{Pr}(Z=z) = \begin{cases}\frac{b+1}{a+b+1} &\text{if }z=0 \\\\ \frac a{a+b+1} & \text{otherwise}\end{cases}[/tex]

find all values of x for which (f∘g)(x)=(g∘f)(x).
f(x)=x/(x+2), g(x)=x^2
Step-by-step explanation:
(f○g)(x) means f(g(x))
(g○f)(x) means g(f(x))
f(g(x)) means to use the expression of g(x) as input to f(x). so, we replace all simple x in f(x) by g(x) = x².
f(g(x)) = x²/(x² + 2)
using the same principle we get for
g(f(x)) = (x/(x + 2))² = x²/(x + 2)²
now we need to solve
x²/(x² + 2) = x²/(x + 2)²
let's multiply both sides with both denominators :
x²(x + 2)² = x²(x² + 2)
x²(x² + 4x + 4) = x²(x² + 2)
so, one solution is clear : x = 0.
because then we have 0 = 0.
for x <> 0 we can divide both sides by x² and get
x² + 4x + 4 = x² + 2
4x + 4 = 2
4x = -2
x = -2/4 = -1/2
both expressions are equal for x = 0 and x = -1/2
