The closest point is (3.5, 1.9) and the distance is 1.96 units
How to determine the point and the distance?The coordinate is given as:
(4, 0)
The equation of the function is
y = √x
The distance between two points is calculated using
d = √(x2 - x1)^2 + (y2 - y1)^2
So, we have the following points
(x1, y1) = (4, 0) and (x2, y2) = (x, 0)
This gives
d = √(x - 4)^2 + (√x - 0)^2
Evaluate the difference
d = √(x - 4)^2 + (√x)^2
Evaluate the exponent
d = √x^2 - 8x + 16 + x
Evaluate the like terms
d = √x^2 - 7x + 16
Next, we differentiate using a graphing calculator
d' = (2x - 7)/[2√(x^2 - 7x + 16)]
Set to 0
(2x - 7)/[2√(x^2 - 7x + 16)] = 0
Cross multiply
2x - 7 = 0
Add 7 to both sides
2x = 7
Divide by 2
x = 3.5
So, we have:
Substitute x = 3.5 in y = √x
y = √3.5
Evaluate
y = 1.9
So, the point is (3.5, 1.9)
The distance is then calculated as:
d = √(x2 - x1)^2 + (y2 - y1)^2
This gives
d = √(3.5 - 4)^2 + (1.9 - 0)^2
Evaluate
d = 1.96
Hence, the closest point is (3.5, 1.9) and the distance is 1.96 units

Part B: Divide the polynomial f (x) by (x2 - x - 2) to
create a rational function g(x) in simplest factored form.
Determine g(x) and find its slant asymptote.
Part C: List all locations and types of discontinuities of
the function g(x).
a) The polynomial f(x) in expanded form is f(x) = x³ + 10 · x² - 20 · x - 24.
b) The rational function g(x) in factored form is g(x) = [(x - 6) · (x + 3)] / (x - 2). there is no slant asymptotes.
c) There is one evitable discontinuity at x = - 1, and one definitive discontinuity at x = 2, where there is a vertical asymptote.
How to analyze polynomial and rational functions
a) In the first part of this question we need to determine the equation of a polynomial in expanded form, derived from its factor form defined below:
f(x) = Π (x - rₐ), for a ∈ {1, 2, 3, 4, ..., n} (1)
Where rₐ is the a-th root of the polynomial.
If we know that r₁ = 6, r₂ = - 1 and r₃ = - 3, then the polynomial in factor form is:
f(x) = (x - 6) · (x + 1) · (x + 3)
f(x) = (x - 6) · (x² + 4 · x + 4)
f(x) = (x - 6) · x² + (x - 6) · (4 · x) + (x - 6) · 4
f(x) = x³ - 6 · x² + 4 · x² - 24 · x + 4 · x - 24
f(x) = x³ + 10 · x² - 20 · x - 24
The polynomial f(x) in expanded form is f(x) = x³ + 10 · x² - 20 · x - 24.
b) The rational function is introduced below:
g(x) = (x³ + 10 · x² - 20 · x - 24) / (x² - x - 2)
g(x) = [(x - 6) · (x + 1) · (x + 3)] / [(x - 2) · (x + 1)]
g(x) = [(x - 6) · (x + 3)] / (x - 2)
The slope of the slant asymptote is:
m = lim [g(x) / x] for x → ± ∞
m = [(x - 6) · (x + 3)] / [x · (x - 2)]
m = 1
And the intercept of the slant asymptote is:
n = lim [g(x) - m · x] for x → ± ∞
n = Non-existent
Hence, there is no slant asymptotes.
c) There is vertical asymptote at a x-point if the denominator is equal to zero. There is one evitable discontinuity at x = - 1, and one definitive discontinuity at x = 2, where there is a vertical asymptote.

The length of a rectangle is twice the width. Given that the perimeter of the rectangle is 24 feet, how many square feet are in the area of the rectangle?
Answer:
Area = 32feet²
Step-by-step explanation:
Perimeter of a rectangule = 2(length+width)
Then:
g = 2w Eq. 1
2(g+w) = 24 Eq. 2
g = length
w = width
From Eq. 2:
(2*g + 2*w) = 24
2g + 2w = 24
2w = 24 - 2g Eq. 3
Matching Eq. 1 and Eq. 3
g = 24 - 2g
g + 2g = 24
3g = 24
g = 24/3
g = 8 feet
From Eq. 1
g = 2w
8 = 2w
8/2 = w
w = 4 feet
Check:
From Eq. 2
2(g+w) = 24
2(8+4) = 24
2*12 = 24

The figure is not drawn to scale.) Solve the triangle.
round your answers to the nearest tenth.
If there is more than one solution, use the button labeled "or".
The given triangle has three angles with measurements: ∠A = 69°, ∠B = 52°, and ∠C = 59° respectively. Using the law of cosines, these angles are calculated from the given lengths of the triangle.
What is the law of cosines?The law of cosines gives the relationship between the lengths of sides and the angles of the triangle ABC.
According to the law of cosines:
Cos A = (b² + c² - a²)/2bc
Cos B = (a² + c² - b²)/2ac
Cos C = (a² + b² - c²)/2ab
Calculation:For the given triangle ABC,
a = 75, b = 63, and c = 69
So, using the law of cosines,
Cos A = (b² + c² - a²)/2bc
⇒ Cos A = (63² + 69² - 75²)/2×63×69
⇒ Cos A = 5/14
⇒ A = Cos⁻¹(5/14) = 69.07
∴ ∠A = 69°
Similarly,
Cos B = (a² + c² - b²)/2ac
⇒ Cos B = (75² + 69² - 63²)/2×75×69
⇒ Cos B = 31/50
⇒ B = Cos⁻¹(31/50) = 51.6 ≅ 52
∴ ∠B = 52°
Cos C = (a² + b² - c²)/2ab
⇒ Cos C = (75² + 63² - 69²)/2×75×63
⇒ Cos C = 179/350
⇒ C = Cos⁻¹(179/350) = 59.2
∴ C = 59°
Thus, the angles of the triangle ABC are 69°, 52°, and 59° respectively.

The baseball team has a double-header on Saturday. The probability that they will win both games is 34%. The probability that they will win the first game is 75%, What is the probability that the team will win the second game given that they have already won the first game?
Considering the definition of conditional probability, the probability that the team will win the second game given that they have already won the first game is 45.33%.
Definition of probabilityProbability is the greater or lesser chance that a given event will occur.
In other words, the probability establishes a relationship between the number of favorable events and the total number of possible events.
Conditional probabilityConditional probability is the probability that a given event will occur given that another event occurs. The conditional probability operator is the │ sign.
In other words, the conditional probability is the probability of some event A , given the occurrence of some other event B and is denoted by P(A|B) and is read “the probability of A , given B ”.
Then, when an event influences the outcome of a second event, the probability of the second event is said to be a conditional probability and is calculated using the expression:
P(A|B)= P(A∩B) ÷ P(B)
where:
the probability of event B cannot be zero.P(A∩B) is the probability of both events happening.Probability that the team win the second gameIn this case, you know that:
B: The baseball team win the first game.A: The baseball team win the second game.The probability that they will win both games is 34% → P(A∩B)= 0.34The probability that they will win the first game is 75% → P(B)= 0.75Replacing in the definition of conditional probability:
P(A|B)= 0.34 ÷ 0.75
P(A|B)= 0.4533= 45.33%

Which of the following equations has a minimum value of (3,-10)? y = 2x2 + 40x + 203 y = x2 + 6x + 19 y = 2x2 − 12x + 8 y = -2x2 + 12x − 8
Answer:
y = 2x² − 12x + 8
Step-by-step explanation:
FIRST METHOD :
y = 2x² − 12x + 8
= (2x² − 12x) + 8
= 2 (x² − 6x) + 8
= 2 (x² − 6x + 9 − 9 ) + 8
= 2 (x² − 6x + 9) − 2×9 + 8
= 2 (x² − 6x + 9) − 18 + 8
= 2 (x² − 6x + 9) − 10
= 2 (x − 3)² − 10
Then ,the equation has a extremum value of (3,-10)
Since the number 2 in the equation y = = 2 (x − 3)² − 10 is greater than 0
(2 > 0) , the graph (parabola) opens upward
Therefore ,the extremum (3,-10) is a minimum.
SECOND METHOD :
the graph of a function of the form f(x) = ax² + bx + c
has an extremum at the point :
[tex]\left( -\frac{b}{2a} ,f\left( -\frac{b}{2a} \right) \right)[/tex]
in the equation : f(x) = 2x² − 12x + 8
a = 2 ; b = -12 ; c = 8
Then
[tex]-\frac{b}{2a} = -\frac{-12}{2 \times 2} = 3[/tex]
Then
[tex]f\left( -\frac{b}{2a} \right) = f(3) = 2(3)^2- 12(3) + 8 = 18 - 36 + 8 = -18 + 8 = -10[/tex]
the graph of a function f(x) = 2x² − 12x + 8
has an extremum at the point (3 , -10)
Since the parabola opens up ,then the extremum (3,-10) is a minimum.

f(4)=14
Step-by-step explanation:
a) u do it by substituting 4 in places where there r 'x'
since this one say f(4) it only can go to the function which says f(x)
f(x)=4x-2
f(4)=4(4)-2, so according to BODMAS rule multiplication comes first rather than subtraction
so, f(4)=16-2=14
f(4)=14
do the others based on this, hope i explained well, if i did, please gimme brainliest :)
Please help, will mark brainliest.
Divide the interval [3, 5] into [tex]n[/tex] subintervals of equal length [tex]\Delta x=\frac{5-3}n = \frac2n[/tex].
[tex][3,5] = \left[3+\dfrac0n,3+\dfrac2n\right] \cup \left[3+\dfrac2n,3+\dfrac4n\right]\cup\left[3+\dfrac4n,3+\dfrac6n\right]\cup\cdots\cup\left[3+\dfrac{2(n-1)}n, 3+\dfrac{2n}n\right][/tex]
The right endpoint of the [tex]i[/tex]-th subinterval is
[tex]r_i = 3 + \dfrac{2i}n[/tex]
where [tex]1\le i\le n[/tex].
Then the definite integral is given by the Riemann sum
[tex]\displaystyle \int_3^5 \sqrt{8+x^2} \, dx = \lim_{n\to\infty} \sum_{i=1}^n \sqrt{8+{r_i}^2} \Delta x = \boxed{\lim_{n\to\infty} \frac2n \sum_{i=1}^n \sqrt{17 + \frac{12i}n + \frac{4i^2}{n^2}}}[/tex]
What is the distance from (-3,8) and (13,-6)?
Answer:
d ≈ 21.26 units
Step-by-step explanation:
calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 3, 8 ) and (x₂, y₂ ) = (13 - 6 )
d = [tex]\sqrt{13-(-3))^2+(-6-8)^2}[/tex]
= [tex]\sqrt{(13+3)^2+(-14)^2}[/tex]
= [tex]\sqrt{16^2+196}[/tex]
= [tex]\sqrt{256+196}[/tex]
= [tex]\sqrt{452}[/tex]
≈ 21.26 units ( to 2 dec. places )
Answer:
The distance is 21.3

Which number can each term of the equation be multiplied by to illuminate the fractions before solving 6-3/4x+1/3=1/2x+5
[tex]\boldsymbol{\sf{6-\dfrac{3}{4}x+\dfrac{1}{3}=\dfrac{1}{y}x+5 }}[/tex]
Convert 6 to the fraction 18/3.
[tex]\boldsymbol{\sf{\dfrac{18}{3} -\dfrac{3}{4}x+\dfrac{1}{3}=\dfrac{1}{y}x+5 }}[/tex]
Since the fractions 18/3 and 1/3 have the same denominator, we add their numerators to calculate them.
[tex]\boldsymbol{\sf{\dfrac{18+1}{3}-\dfrac{3}{4}x=\dfrac{1}{2}x+5 \ \longmapsto \ \ [Add \ 18+1] }}[/tex]
[tex]\boldsymbol{\sf{\dfrac{19}{3}-\dfrac{3}{4}x=\dfrac{1}{2}x+5 }}[/tex]
Subtract [tex]\bf{\frac{1}{2}x }[/tex] on both sides.
[tex]\boldsymbol{\sf{\dfrac{19}{3}-\dfrac{3}{4}x-\dfrac{1}{2}x=5 }}[/tex]
Combine [tex]\bf{-\frac{3}{4}x}[/tex] and [tex]\bf{-\frac{1}{2}x}[/tex] to get [tex]\bf{-\frac{5}{4}x}[/tex].
[tex]\boldsymbol{\sf{\dfrac{19}{3}-\dfrac{5}{4}x=5 }}[/tex]
Subtract 19x from both sides.
[tex]\boldsymbol{\sf{-\dfrac{5}{4}x=5-\dfrac{19}{3} }}[/tex]
Convert 5 to the fraction 15/3.
[tex]\boldsymbol{\sf{-\dfrac{4}{5}x=\dfrac{15}{3}-\dfrac{19}{3} }}[/tex]
Since the fractions 15/3 and 19/3 have the same denominator, we add their numerators to calculate them.
[tex]\boldsymbol{\sf{-\dfrac{5}{4}x=\dfrac{15-19}{3} \ \longmapsto \ \ [Subtract \ 15-19] }}[/tex]
[tex]\boldsymbol{\sf{-\dfrac{5}{4}x=-\dfrac{4}{3} }}[/tex]
Multiply both sides by -4/3, the reciprocal of -4/3.
[tex]\boldsymbol{\sf{x=-\dfrac{4}{5}\left(-\dfrac{4}{5}\right) }}[/tex]
Multiply -4/3 by -4/5 (to do this, multiply the numerator by the numerator and the denominator by the denominator).
[tex]\boldsymbol{\sf{x=\dfrac{-4(-4)}{3\times5} \ \ \longmapsto \ \ Multiply, \ numerator \ and \ denominator. }}[/tex]
[tex]\red{\boxed{\boldsymbol{\sf{\blue{Answer \ \ \longmapsto \ \ \ \ x=\frac{16}{15} }}}}}[/tex]
