What irrational number is associated with a point on a number line?
In this problem we find the location of a point on a number line, which is related to an inexact irrational number, that is, an irrational number that is not equivalent to any rational number. The point is between two exact irrational numbers, that is, √16 = 4 and √25 = 5.
There are two options: (i) √17, (ii) √24. √24 is close to 5, but √17 is close to 4. Thus, the number shown on the number line could be related to the inexact irrational number √17.

if alpha and beta are the roots of the equation 4 x square - 5 x - 1 equals to 0 find the quadratic equation whose roots are two minus alpha coma to minus beta
Answers
Answer:
4x² -11x +5 = 0
Step-by-step explanation:
Given α and β are roots of 4x² -5x -1 = 0, you want to find the quadratic equation that has (2-α) and (2-β) as its roots.
Factored formFactoring out the leading coefficient, we can write the factored form of the given quadratic as ...
4(x -α)(x -β) = 0 = 4x² -5x -1
When the roots are changed from α and β to (2-α) and (2-β), the factored form of the new equation is ...
4(x -(2 -α))(x -(2 -β)) = 0
4(x -2 +α)(x -2 +β) = 0
Negating both factors allows us to write this in a familiar form:
4((2 -x) -α)((2 -x) -β) = 0
Comparing to the original factored quadratic, we see that this is the original with x replaced by (2 -x). Then the quadratic we seek is ...
4(2-x)² -5(2 -x) -1 = 0 . . . . . . . . . . . original with x replaced by (2-x)
4(4 -4x +x²) -10 +5x -1 = 0 . . . . simplify a bit
4x² -11x +5 = 0 . . . . . . . . . . simplify
The quadratic whose roots are (2-α) and (2-β) is 4x² -11x +5 = 0.

questionamy is eight years older than twice her cousin alicia’s age. the sum of their ages is less than 32.let x represent alicia's age.which inequality represents alicia’s possible age?
Answers
An inequality that represents Alicia’s possible age is x < 8.
For given question,
let x represent Alicia's age.
Amy is eight years older than twice her cousin Alicia’s age.
So, Amy's age would be 2x + 8
The sum of their ages is less than 32.
We write above statement in mathematical expression.
sum of their ages = (2x + 8) + x
= 3x + 8
The sum of their ages is less than 32.
We use the symbol < for 'less than'
So, the mathematical expression form of given statement would be,
(3x + 8) < 32
So, we get an inequality 3x + 8 < 32
⇒ 3x < 32 - 8
⇒ 3x < 24
⇒ x < 24/3
⇒ x < 8
Therefore, an inequality that represents Alicia’s possible age is x < 8.

A soup recipe requires 6 ounces of bouillon plus 2 ounces for each quart of water used.
This relationship is represented by the equation b = 2q +6, where b represents the
number of ounces of bouillon and q represents the number of quarts of water
Answers
Answer:
Slope=1.000/2.000=0.500
b-i
q-i
b-(2*q+6)=0
Step-by-step explanation:
1.1 Solve b-2q-6 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line b-2q-6 = 0 and calculate its properties
Notice that when b = 0 the value of q is 3/-1 so this line "cuts" the q axis at q=-3.00000
q-intercept = 6/-2 = 3/-1 = -3.00000
When q = 0 the value of b is 6/1 Our line therefore "cuts" the b axis at b= 6.00000
b-intercept = 6/1 = 6.00000
Slope is defined as the change in q divided by the change in b. We note that for b=0, the value of q is -3.000 and for b=2.000, the value of q is -2.000. So, for a change of 2.000 in b (The change in b is sometimes referred to as "RUN") we get a change of -2.000 - (-3.000) = 1.000 in q. (The change in q is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 1.000/2.000 = 0.500
Slope = 1.000/2.000 = 0.500
b-intercept = 6/1 = 6.00000
q-intercept = 6/-2 = 3/-1 = -3.00000

Don't know if this will help but if your looking for an endpoint, I did -2 = x+7/2 To find X. I got -2 from the X coordinate with midpoint. To get rid of the fraction I multiplied by 2 which leads to -4=x+7 since it cancels out the denominator/bottom fraction. X should be -11. Same thing with Y coordinate. 3= y- 17/2. Should give you 6=y- 17 which then becomes Y=23.

The volume of a rectangular prism if the length is 10ft is 250ft2.
What is a prism?A transparent optical prism is a device intended to refract light and has flat, polished surfaces. Prisms do not have two parallel surfaces; at least one of their surfaces must be slanted. Since a triangular prism with a triangular base and rectangular sides is the traditional geometrical shape of an optical prism, this type is typically meant when the word "prism" is used in everyday speech. Certain optical prism varieties don't actually have geometric prism shapes. Any material that transmits the wavelengths for which it is intended can be used to create prisms. Glass, acrylic, and fluorite are common building blocks.
From description, l = 2h = 2w
Since it has a square base,w=h
V = lwh = 2w•w•w = 2w3
Surface area, A = 2(wl+hl+hw) = 2(2w2+2w2+w2) = 250
5w2=250/2 = 125
w2= 25
V= 2(5)3 = 2(125)= 250 ft2
