Step-by-step explanation:

The absolute maximum of the function is 184 and the minimum value of the function is -72.

If the graph of an absolute value function opens downward, the y-value of the vertex is the maximum value of the function.

Given the function f(x) = x⁴-18x²+9 at the interval [-5, 5], the absolute maximum and minimum values at this endpoints are as calculated;

At end point x = -5

f(-5) = (-5)⁴-18(-5)²+9

f(-5) = 625-450+9

f(-5) = 184

At end point x = 5

f(5) = (5)⁴-18(5)²+9

f(5) = 625-450+9

f(5) = 184

To get the critical point, this point occurs at the turning point i.e at

dy/dx = 0

if y = x⁴-18x²+9

dy/dx = 4x³-36x = 0

4x³-36x = 0

4x (x²-9) = 0

4x = 0

x = 0

x²-9 = 0

x² = 9

x = ±3

Using the critical points [0, ±3]

when x = 0, f(0) =  0⁴-18(0)+9

f(0) = 9

Similarly when x = 3, f(±3)=  (±3)⁴-18(±3)²+9

f(±3) = 81-162+9

f(±3) = -72

It can be seen that the absolute minimum occurs at x= ±5 and the absolute minimum occurs at x =±3

absolute maximum = 184

absolute minimum = -72

Hence, the absolute maximum of the function is 184 and the minimum value of the function is -72.

If there are 5 orange beads, and 3 purple beads, that means there is 8 beads that aren't pink in the bag.

If the rest are pink, and it's 3/5, that means 8 is 2/5. Divide by 2, and 4 is 1/5.

We can conclude that there are 12 pink beads, which is 3/5 of the total beads, by adding 2/5 and 1/5 (8 and 4)

Hey there!

In order to find the area of a triangle, you need to:

Multplipy the base by the height

Then you take that product and multiply it by 1/2 (basically divide it by 2)

Then you get your area!

Base: 19

Height: 12

19 x 12

228

228 x 1/2

228/2

114

So the area of this triangle is [tex]144[/tex] [tex]inches^2[/tex]

---Multiply a x c

Quadratic Form: ax^2 + bx + c

4 x -25 = -100

---Find a factor pair of -100 that adds up to -15

-20 x 5 = - 100

-20 + 5 = -15

---Separate the b term into your two factors

4n^2 + 5n - 20n - 25

This can take some trial and error (though there are only two options) because when you factor, you want the inside of the parentheses to be the same. If you look at the next step, (4n + 5) appears twice.

---Factor each binomial

n(4n + 5) - 5 (4n + 5)

---Rewrite

(n - 5)(4n + 5)

What you're really doing here is factoring out the (4n + 5), which leaves you with the terms that you factored out in the previous step. You then combine these terms into one set of parenthesis.

Answer: (n - 5)(4n + 5)

∠ABO = ∠BOC = 60° (alternate-interior angles)

……………………………………………

In ΔOAB ,we have :

OA = OB and ∠ABO = 60°

Then ,

ΔOAB is an equilateral triangle.

then
