What values of A and B will result in an equation with infinite solutions? Enter the answers in the boxes.
A=

Answers

Answer:

A =  6  +  B /x −  4 /x

B  =  Ax  +  4  −  6 x

x = b-4/a-6

Step-by-step explanation:

hope this helps :)

The values of A and B that will result in an equation with infinite solutions are 6 and 4

Infinite solution of an equation

For an equation to have infinite number of solutions, the equations on both sides must be the same,

Given the equation

Ax + 4 = 6x + B

If the equation has infinite number of solution, then

Ax = 6x

A= 6

Similarly

4 = B

B = 4

Hence the values of A and B that will result in an equation with infinite solutions are 6 and 4

Question 5 of 10
The graph shows the function f(x) = 2^x.
What is the value of x when f(x) = 4?

Answers

Answer:

A. 2

Step-by-step explanation:

Our y-axis is equivalent to f(x), so we can use it to find the value of x when f(x) = 4. If we look at the graph, we can find that an f(x) value of 4 (or, a y-value of 4) has an x-value of 2.

We could also figure this out by making f(x) equal to 4 in the equation:

[tex]4=2^{x}[/tex]

2 times itself how many times is equal to 4? Well, 2 times 2 is equal to 4, so 2 times itself two times is equal to 4. x is equal to 2:

[tex]4=2^{2}[/tex]

Either way works. If you have any more questions, let me know! :)

A company estimates that it can sell 3,000 units each month of its product if it prices each unit at $80. However, its monthly number of sales will increase by 10 units for each $0.10 decrease in price. The company has fixed costs of $250. The cost to make each unit is $4.20. Find the level of production that maximizes the company's profit.

The Should Produce _________
Units at a price of $__________
Which will yield a profit of $_______

Answers

9514 1404 393

Answer:

5290 units$57.10 per unit$279,591 profit

Step-by-step explanation:

For price p, the quantity q of units sold is said to be ...

  q = 3000 +10(80-p)/0.10 . . . . for price in dollars

Then the revenue will be ...

  r(p) = p·q = p(3000 +100(80-p)) = 100p(110 -p)

The cost is said to be ...

  c(q) = 250 +4.20q

  c(p) = 250 +4.20(100(110 -p)) = 250 +420(110 -p)

Then the profit function is ...

  P(p) = r(p) -c(p)

  P(p) = 100p(110 -p) -(250 +420(110 -p)) = (110 -p)(100p -420) -250

__

Ignoring the vertical offset of -250, the quadratic has zeros at 110 and 4.2. So, its line of symmetry (and vertex) will be found at ...

  p = (110 +4.2)/2 = 57.1 . . . . dollars per unit

The quantity that should be produced at that price is ...

  q(57.1) = 100(110 -57.1) = 5290 . . . . units produced

The profit at that price is ...

  P(57.1) = (110 -57.1)(100·57.1 -420) -250 = 52.9(5290) -250

  = $279,591 . . . . best profit

_____

Additional comment

After you have seen a few of these, you can write down the revenue function based on the rate of change of units sold.

If p is the price of a unit, then 80-p is the number of dollars of decrease in price for a price of p. Then (80 -p)/0.10 is the number of 10¢ decreases in price. The increase in units sold is 10 times this, or 10(80 -p)/0.10 = 100(80 -p). When that is added to 3000 units sold, the total is ...

  3000 +100(80 -p) = 3000 +8000 -100p

  = 11000 -100p = 100(110 -p) . . . . . quantity sold at price p

Revenue is the product of price times the number of units sold at that price.

Profit is the difference between revenue and cost.

y = - [tex]\frac{1}{2}[/tex] x + 1

Step-by-step explanation:

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (4, - 1) ← 2 points on the line

The  price that would maximize total revenue would be $ 23.

As long as that a football team charges $ 30 per ticket and averages 20,000 people per game, and each person spend an average of $ 8 on concessions, and for every drop of $ 1 in price, the attendance rises by 800 people, to determine what ticket price should the team charge to maximize total revenue, the following calculation must be performed:

20,000 x 30 + 20,000 x 8 = 760,000 24,000 x 25 + 24,000 x 8 = 792,00024,800 x 24 + 24,600 x 8 = 792,00025,600 x 23 + 25,600 x 8 = 793,600  26,400 x 22 + 26,400 x 8 = 792,000

Grams is used for smaller objects, and liters is used for a liquid, centimeters, is used to measure distance, and same with yards,feet,kilometers, meters. the correct answer is pounds.

Ron weighs the books so he uses to pound unit to measure the weight of the books.

What are units of measurement?

The group of units used to quantify different physical quantities is collectively known as the units of measurement. Since ancient times, we have measured these things using many units, including length, mass, volume, current, and temperature. Since then, these units of measurement have changed, and we now use new, more practical and user-friendly systems of measurement.

Centimetres are used to measure distance, same as yards, feet, kilometres, and metres are used to measure larger objects, liquids are measured in litres, and tiny objects are measured in grammes.

Since Ron weighs the books so he uses to pound unit to measure the weight of the books.

Therefore, the correct answer would be pound.

Hence, he weighs the books so he uses to pound unit to measure the weight of the books.

Two skyscrapers are under construction in Atlanta. They will sit on opposite sides of Peachtree St. and

the front view of the two buildings and included the following statement: ABCD ~ JKLM. It was also given

b.) Which line segments could be used to model the height of the smaller building?

c.) What is the height of the taller building? Explain your reasoning.

d.) What is the height of the smaller building? Explain your reasoning.

e.) Would it make sense to say that the scale factor from smaller building to taller building is 3/4?
Explain your reasoning.

Answers

A rectangle is a quadrilateral which has the length of its opposite sides to be equal. Thus, the following are the solutions to the questions:

a) The rectangle used to model the taller building is ABCD.

b) The line segment used to model the height of the smaller building is JM = KL.

c) The height of the taller building is 200 feet.

d) The height of the smaller building is 150 feet.

e) Yes, the scale factor from small to tall building is [tex]\frac{3}{4}[/tex].

Rectangles have equal length of opposite sides , and the sum of its interior angles to be [tex]360^{o}[/tex]. Since the two given skyscrapers were modeled with respect to rectangles ABCD and JKLM, then the answers to the questions are:

a) The rectangle used to model the taller building is ABCD. Since the length of a rectangle is always greater than its width. So that the height; AD = BC.

b) The line segment that can be used to model the height of the smaller building is; JM = KL. This represent the width of the rectangular model for the small building.

c) The height of the taller building is AD = BC = 200 feet. The width of a rectangle is often smaller than its length, which in this case is the height.

d) The height of the smaller building is JM = KL = 150 feet. The length of a rectangle is usually longer than its width.

e) Yes, it would make sense because:

scale factor = [tex]\frac{height of the smaller building}{height of the taller building}[/tex]

                   = [tex]\frac{150 ft}{200ft}[/tex]

                   = [tex]\frac{15}{20}[/tex]

scale factor = [tex]\frac{3}{4}[/tex]

Answer:

Interval notation:  (-∞, 4]

Step-by-step explanation:

Given the quadratic function, f(x) = -(x + 5)(x + 1), where the vertex occurs at point, (-3, 4):

Since the graph of the parabola opens down, then it means that the vertex  is its maximum point. In reference to the vertical points on the graph (i.e., the range values), then the vertex sets the maximum range value of k = 4. This implies that the maximum possible range value is from negative infinity to positive 4.

Therefore, the range of the function is: all real numbers less than to or equal to 4.
