Answer:

  a. $16.90

  b. 23.5%

Step-by-step explanation:

a. After the two discounts, the original price is multiplied by ...

  (1 -10%)(1 -15%) = 0.90×0.85 = 0.765

Then the original price is found from ...

  $12.93 = 0.765 × original price

  original price = $12.93 / 0.765 ≈ $16.90

__

b. The effective discount from the original price is ...

  1 -0.765 = 0.235 = 23.5%

Step-by-step explanation:

To find the derivative of

3x+5, apply sum rule

\( \frac{d}{dx}(3x + 5) = \frac{d}{dx} 3x + \frac{d}{dx} 5\)

The derivative of

\( \frac{d}{dx} kx = k\)

And

\( \frac{d}{dx} c = 0\)

So we have

\( \frac{d}{dx} 3x + 5 = 3\)

So the derivative of the function is 3,

Since linear equations have a constant slope, the slope at any point will be 3.

So the slope of the tangent line is 3.

Answer: Shop A

15% of 240 is 36 and 240-36 is 204 so shop B is more expensive.

The price of a telephone at shop A is less than the price of a telephone at shop B. Then the telephone is bought from shop A.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

The price of a telephone is $200 in shop A and $240 in shop B. If you get a 15% discount shop B.

The price of the telephone after the discount at shop B will be given as,

⇒ (1 - 0.15) x $240

⇒ 0.85 x $240

⇒ $204

The price of a telephone at shop A is less than the price of a telephone at shop B. Then the telephone is bought from shop A.

Answer:

9 7/8

Step-by-step explanation:

1. 4 3/8 can be converted into the improper fraction 35/8, and 5 1/2 can be converted into 11/2.

2. Now that we have 35/8 + 11/2, we have to find a common denominator. Since 2 goes into 8 four times, we can turn 11/2 into 44/8 by multiplying the numerator and denominator (the top and the bottom numbers) by 4.

3. Now we have 35/8 + 44/8. At this point, the all we have to do is add the numerators (the top numbers). 35+44=79, so our answer is 79/8, which we can simplify to 9 7/8.

The property lose $5,400.33 by 2050 and it is by $5197.46 less.

A model function is a way of describing a real-life system or situation using mathematical concepts and language

The initial  function is g(x) = 250(0.9)^x and the new function is g(x) = 250(0.88)^x

In 2050, x = 2050 -2020 = 30.

Using g(x) = 250(0.9)^x and x = 30:

g(x) = 250(0.9)^30 = $10,597.79    (Remember: multiply by 1000)

Using g(x) = 250(0.88)^x and x = 30:

g(x) = 250(0.88)^30 = $5,400.33

Thus, the property lose $5,400.33 by 2050.

Answer:

(x-1)(x-4)

Step-by-step explanation:

I used long division with polynomials to help me find the other factor to this problem.  Divide x cubed -5x squared -6x+8 by x+2 to get x squared -5x+4.

Hope this helps!

Answer:  (x + 2) (x - 4) (x - 1)

Step-by-step explanation:

Use synthetic division. If the remainder (last digit) is zero, then it is a factor. The other digits represent the coefficients of the reduced polynomial.

x³ - 3x² - 6 + 8   ; x + 2 = 0  --> x = -2

-2  |  1   -3    -6    8

    |  ↓   -2   10   -8  

       1    -5    4    0    → remainder is 0

Reduced polynomial: x² -5x + 4

                                = (x - 4) (x - 1)

Factored form: (x + 2) (x - 4) (x - 1)

The minimum surface area that such a box can have is 380 square

Represent the base length with x and the bwith h.

So, the volume is

V = x^2h

This gives

x^2h = 500

Make h the subject

h = 500/x^2

The surface area is

S = 2(x^2 + 2xh)

Expand

S = 2x^2 + 4xh

Substitute h = 500/x^2

S = 2x^2 + 4x * 500/x^2

Evaluate

S = 2x^2 + 2000/x

Differentiate

S' = 4x - 2000/x^2

Set the equation to 0

4x - 2000/x^2 = 0

Multiply through by x^2

4x^3 - 2000 = 0

This gives

4x^3= 2000

Divide by 4

x^3 = 500

Take the cube root

x = 7.94

Substitute x = 7.94 in S = 2x^2 + 2000/x

S = 2 * 7.94^2 + 2000/7.94

Evaluate

S = 380

Hence, the minimum surface area that such a box can have is 380 square

Answer: C

Step-by-step explanation:

Point D is at -14 on the number line.

In Mathematics, the midpoint of a line segment with two end points can be calculated by adding each end point on a line segment together and then divide by two (2).

Since E is the midpoint of line segment CD, we can logically deduce the following relationship:

Line segment CD = Line segment C + Line segment D

Midpoint E = (point C + point D)/2

By substituting the given points into the equation above, we have the following:

Answer:

it is not always true that 75% of a number will be greater than 50% of any other number

Step-by-step explanation:

Leila's statement is not true. It is possible for 50% of a number to be greater than 75% of another number.

For example, consider the numbers 10 and 100. 50% of 10 is 5, and 75% of 100 is 75. In this case, 50% of 10 (5) is greater than 75% of 100 (75).

Here's another example: 50% of 20 is 10, and 75% of 30 is 22.5. In this case, 50% of 20 (10) is again greater than 75% of 30 (22.5).

Therefore, it is not always true that 75% of a number will be greater than 50% of any other number.

Answer: The area of the floor of the store room is 1080 m^2

Step-by-step explanation:

We can begin by using the information provided about the ratios of the dimensions of the store room to set up a system of equations.

Let's call the height of the store room h, the length l, and the breadth b.

From the first ratio given, we know that:

h/l = 5/4

From the second ratio given, we know that:

h/b = 2/3

We can also use the information about the total area of the four walls to set up another equation.

The total area of the four walls is the sum of the area of the top and bottom walls (length x height) and the area of the two side walls (breadth x height).

So we have:

2lh + 2bh = 2760

We can now use the first two equations to solve for one of the variables in terms of the other two.

We can cross-multiply and simplify the first equation:

l = (4/5)h

We can cross-multiply and simplify the second equation:

b = (3/2)h

We can now substitute these expressions for l and b into the equation for the total area of the four walls:

2(4/5)h^2 + 2(3/2)h^2 = 2760

Solving for h, we get:

h = 30

Now that we know the value of h, we can use the equations l = (4/5)h and b = (3/2)h to find the values of l and b.

l = (4/5)h = (4/5)(30) = 24

b = (3/2)h = (3/2)(30) = 45

Now we have all the information we need to find the area of the floor, which is the product of the length and breadth of the store room

Area of floor = lb = 2445 = 1080 m^2

Explanation: By using the information about the ratios of the dimensions of the store room and the total area of the four walls, we set up a system of equations and used algebra to solve for the height, length and breadth of the store room. With this information, we were able to find the area of the floor of the store room.

e. None of the above.

what is algebra?

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas.

To check whether the relation is functional, we need to make sure that each x-value is associated with only one y-value.

We can see that the pairs (6,7), (-2,9), (8,8), and (-4,9) all have different x-values, and therefore are associated with different y-values. This means that the relation is currently functional.

To determine which ordered pair could not be substituted so that the relation is functional, we need to find an x-value that is associated with two different y-values.

Let's look at each of the answer choices and see if they fit this criteria:

a. (9,9): This pair does not already appear in the relation, so it's possible that it could be added without affecting the functionality of the relation.

b. (2,9): This pair does not already appear in the relation, so it's possible that it could be added without affecting the functionality of the relation.

c. (7,8): This pair does not already appear in the relation, so it's possible that it could be added without affecting the functionality of the relation.

d. (8,3): This pair does not already appear in the relation, so it's possible that it could be added without affecting the functionality of the relation.

Since none of the answer choices would result in an x-value being associated with two different y-values, the correct answer is:

Answer:

38.9?? or 40??

Step-by-step explanation:

you  put the base and the height together then multiply it by 2

The function representing the situation is f(x) = 2(x + 1)^2 + 2. Option C.

To determine which function represents the given situation, we can use the information provided about the minimum point and the point on the parabola.

We are given that the minimum of the graph of the quadratic function is located at (-1, 2). This means that the vertex of the parabola is at (-1, 2).

The standard form of a quadratic function is f(x) = a(x - h)^2 + k, where (h, k) represents the vertex.

In this case, h = -1 and k = 2, so the equation becomes f(x) = a(x + 1)^2 + 2.

Additionally, we know that the point (2, 20) lies on the parabola. We can substitute these coordinates into the equation to solve for the value of a:

20 = a(2 + 1)^2 + 2

20 = 9a + 2

18 = 9a

a = 2

Substituting the value of a back into the equation, we have:

f(x) = 2(x + 1)^2 + 2

So the function that represents the given situation is f(x) = 2(x + 1)^2 + 2, which is option C.
