If y=2x-8 what is the minimum value of the product xy
The minimum value of the product is -8.
What is the minimum value?The minimum value is the y value of the lowest point on the graph.
The function y = 2x-8 and we have to find the minimum value of the XY.
Plugging the value of y in the product;
[tex]\rm f(x)=x(2x-8)\\\\f(x)=2x^2-8x[/tex]
f(x) represents an upward parabola and we know that for an upward parabola, the minimum point is the vertex.
So in order to find the minimum value, we find the y coordinate of the vertex of the parabola.
The x-coordinate of the parabola is given by;
[tex]\rm = \dfrac{-b}{2a}\\\\=\dfrac{-8}{2\times 2}\\\\ =\dfrac{-8}{4}\\\\=-2[/tex]
The y -coordinate of the parabola is;
[tex]\rm f(x)=2x^2-8x\\\\f(2)=2(2)^2-8(2)\\\\f(2)=2\times 4-16\\\\ f(2)=8-16\\\\ f(2)=-8[/tex]
The vertex is (2,-8)
Hence, the minimum value of the product is -8.

evaluate (√2 + √3)² (√5 - √2)²
Answer:
35 -10√10 + 14√6 - 8√15Step-by-step explanation:
(√2 + √3)² · (√5 - √2)²
use (a ± b)² = a² ± 2ab + b²
= [(√2)² + 2(√2)(√3) + (√3)²] · [(√5)² - 2(√5)(√2) + (√2)²]
= (2 + 2√6 + 3) · (5 - 2√10 + 2)
= (5 + 2√6)(7 - 2√10)
use FOIL: (a + b)(c + d) = ac + ad + bc + bd
= (5)(7) + (5)(-2√10) + (2√6)(7) + (2√6)(-2√10)
= 35 - 10√10 + 14√6 - 4√60
= 35 - 10√10 + 14√6 - 4√(4 · 15)
= 35 - 10√10 + 14√6 - 4 · √4 · √15
= 35 -10√10 + 14√6 - 4 · 2 · √15
= 35 -10√10 + 14√6 - 8√15

C) 14
D) 15
As per the Intersecting Chords theorem, if two chords cross in a circle, the products of the chord segments' measures are equal. The measure of the line segment is DF is 14 units.
What is Intersecting Chords theorem?If two chords cross in a circle, the products of the chord segments' measures are equal.
As per the Intersecting Chords theorem, the product of DF and FB will be equal to the product of CF and FA, therefore,
DF×FB = CF×FA
(x+8) × 8 = 16 × 7
(x+8) = (16×7)/8
(x+8) = 14

tank. Write an equation to represent the number of gavons of gas g in her
tank after d days. Then, find the amount of gas in her tank after 8 days.
linear application
The amount of gas in her tank after 8 days given the linear equation g = 213 - 1.6d is 200.2 gallons of gas
Linear equationGallons of gas used per day = 1.6 gallonsNumber of days = dQuantity of gas = gThe equation
g = 213 - 1.6d
Gas remaining after 8 days
g = 213 - 1.6(8)
= 213 - 12.8

What is the probability?Probability is the branch of mathematics, which discusses the occurrence of a random experiment.
