Conclusion:

To transform f(x) = 2x² – 44x + 185, start by factoring out 2 from the first two terms.

Next, create a perfect square trinomial while preserving the function's value:

f(x) = 2(x² – 22x + 121) + 185 – 242

The final expression in vertex form becomes f(x) = 2 (x – 11 )² + -57.

The equation is:
f(x) = 2x² - 44x + 185
f(x) = 2(x² - 22x + 121 - 121) + 185 =
= 2(x² - 22x + 121) - 242 + 185 =
= 2(x - 11)² - 57
Conclusion:
The vertex is located at (11, -57) and the vertex form is: f(x) = 2(x - 11)² - 57

The graphs of f(x) = 10x and its translation, g(x), are shown. On a coordinate plane, 2 exponential functions are shown. f (x) a
PIT_PIT [12445]

Answer:

g(x)=(10)^{x-3}

Detailed explanation:

* Let’s clarify the procedure for solving this problem

- An exponential function can be expressed as f(x)=a(b)^{x}, where

 a signifies the starting amount (x = 0), and b denotes the growth factor

- If b > 1, it qualifies as an exponential growth function

- If 0 < b < 1, it is categorized as an exponential decay function

- Horizontal translation to the right by h units results in the new function being g(x)=a(b)^{x-h}

- Conversely, if translated to the left by h units, the function modifies to g(x)=a(b)^{x+h}

 the new function will be

- A vertical upward shift by k units alters the function to g(x)=a(b)^{x}+k

- A vertical downward shift by k units means the new function accounts for g(x)=a(b)^{x}-k

* Now, let’s solve the problem

∵ f(x) is an exponential function

∵ The points (0, 1), (1, 10), (2, 100) are points of f(x)

- g(x) is the transformation of f(x)

∵ The points (3, 1), (4, 10), (5, 100) belong to g(x)

∵ The point (0, 1) on f(x) transforms to (3, 1) on g(x)

∵ The point (1, 10) on f(x) transforms to (4, 10) on g(x)

∵ The point (2, 100) on f(x) translates to (5, 100) on g(x)

∵ Notably, all y-coordinates of f(x) match those of g(x)

 indicating no vertical translation

∴ Hence, no vertical translation occurred

∵ The x-coordinates of f(x) are increased by

   3 units to yield the x-coordinates for g(x)

∴ This shows that f(x) is translated 3 units to the right

∵ f(x)=(10)^{x}

∴ g(x)=(10)^{x-3}

- Refer to the corresponding graph for greater clarity

# The red curve denotes f(x)

# The blue curve signifies g(x)

A hollow sphere sits snugly in a foam cube so that the sphere touches each side of the cube. Find the volume of the foam.
Leona [12618]

Answer:

                          π

V-foam = 4r³( 2 - ----- )

                             3

Step-by-step explanation:

Let r denote the radius of the sphere. The volume of the sphere is expressed as

V = (4/3)(π)(r³).

Next, understand that the cube's side length is 2r, hence the cube's volume is

V = (2r)³, which equals 8r³.

The volume of the foam is derived from the cube's volume subtracting that of the sphere:

V-foam = 8r³ - (4/3)(π)(r³). This can be simplified to

                          π

V-foam = 4r³( 2 - ----- )

                             3

lawyer [12517]
I am hesitant to provide a definite answer since I'm not completely certain, but it's clear you can discard options C and D right away since the rate of change cannot be negative. Between options A and B, I would lean towards option B. I would have asked you to consider me the brainliest if I were correct, but I suspect this is for the IA4, where you're unable to check your grade... haha. Apologies, but I hope this assists you in some way!

If Ana devotes all her time to making fudge, she can make 3 pounds of fudge an hour, and if he devotes all her time to making to
lawyer [12517]

Answer: Ana should produce more fudge, and Leo should produce more toffee.

Step-by-step explanation:

Comparative advantage defined: A person or country has a comparative advantage producing a good if their opportunity cost for it is lower than someone else's.

In this case, Ana and Leo will both benefit if they focus on the product for which they have the lower opportunity cost.

(a) Ana’s production possibilities:

If she spends all her time making fudge: 3 pounds; or toffee: 2 pounds.

Opportunity cost of 1 pound fudge = 2/3 = 0.66 pounds toffee

Opportunity cost of 1 pound toffee = 3/2 = 1.5 pounds fudge

(b) Leo’s production opportunities:

All time making fudge: 4 pounds; or toffee: 5 pounds.

Opportunity cost of 1 pound fudge = 5/4 = 1.25 pounds toffee

Opportunity cost of 1 pound toffee = 4/5 = 0.8 pounds fudge

Since Ana’s opportunity cost for fudge is lower than Leo’s, she should specialize in fudge production.

Conversely, Leo has a lower opportunity cost for toffee, so he should focus on producing toffee.
