Step-by-step explanation:

There could be multiple ways of doing this. I would personally...

Add all the test scores together.

Then divide the amount of scores.

For example:

90 + 87 + 82 + 91 + 95 = 445

c. -1(1)/(2),(1)/(4),2
b. 1(1)/(2),(1)/(4),-2
d. -1(1)/(2),-(1)/(4),2

Answers

Answer:

Step-by-step explanation:

Rational zeros of f(x) = 8x³-6x²-23x +6 is equals to [tex]2, \frac{-3}{2} , \frac{1}{4}[/tex].

What are rational zeros?

"A rational zero of a polynomial P(x) is defined as when the variable x = p/q  and P (p/q) = 0 where p and q are any integers."

According to the question,

Given,

f(x) = 8x³-6x²-23x +6

Factor of 6 'p' =±1, ±2, ±3, ±6

Factor of 8 'q' = ±1 , ±2, ±4 , ±8

Using trial and error method x=2 is a common factor

Substitute x=2 in f(x) we get,

f(2) = 8(2)³ -6(2)² -23(2) +6

     = 64-24-46+6

      =0

(x-2) is a factor of f(x).

Divide f(x) by (x-2)

[tex]\frac{8x^{3}-6x^{2} -23x+6 }{(x-2)}[/tex]

= 8x²+10x-3

Factorize it we get,

8x²+12x-2x-3

= 4x(2x+3) - 1(2x+3)

= (4x-1)(2x+3)

For rational zeros ,Substitute f(x=(p/q)) =0

x-2=0

x=2

2x+3=0

x= -3/2

     = [tex]-1\frac{1}{2}[/tex]

4x-1 =0

x=1/4

Hence, Option (C) is the correct answer.

List all of the different natural numbers that each leave a remainder of 2 when divided into 83

Answers

Answer:

1, 3, 9, 27, 81

Step-by-step explanation:

A remainder of 2 indicated that the multiplication of any factors will be two less than 83.

Step 1: 83-2=81

Step 2: Find all factors of 81

1, 3, 9, 27, 81

All the different natural numbers are;

⇒ 3, 6, 9, 81

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

All the different natural numbers that each leave a remainder of 2 when divided into 83.

Since, The remainder is 2

So, The value of number = 83 - 2

                                       = 81

Now, All the factors of 81 are,

⇒ 3, 6, 9, 81

Thus, All the natural number which divides the 83 and leave the remainder 2 are,

⇒ 3, 6, 9, 81

Which of the following is an equation of the line tangent to the graph of x^2 - 3xy = 10 at the point (1, -3)?

Answers

Answer:

Step-by-step explanation:

slope = m = y'

x² - 3xy = 10

2x - 3y - 3xy' = 0

at (1, -3)

2(1) - 3(-3) - 3(1)y' = 0

2 + 9 = 3y'

y' = 11/3

equation of tangent:

y = -3 + (11/3) (x - 1) = 11x/3 - 20/3

Plant food is indeed dung or a mix of nitrates that are also given to soil to make it fruitful. Plant fertilizers are available in a variety of formats in the market, including water-soluble plant fertilizer, sustained-release crop fertilizer, and many others. Natural organic food is the best option for fertilizing.

Feeding the plants on a normal basis ensures optimum growth, the production of attractive blossoms and fruit, and the developing resistance to harsh weather and disease.As only one amount of plant-based foods remains every day, this connection is not a function. This statement is about the connection between the group of plant food left and the length of stay.

Answers

Esta pregunta esta incompleta

Pregunta completa

El señor Juan tiene una tienda de abarrotes y sus ventas son al mayoreo y al menudeo. La semana pasada recibió dos toneladas de azúcar en 40 sacos de 50 kg cada uno.

Con el azúcar de un saco empacó bolsas de 250 cada una.¿cuantas bolsas en paco​

Answer:

200 bolsas.

Step-by-step explanation:

Se nos dice en la pregunta,

La semana pasada recibió dos toneladas de azúcar en 40 bolsas de 50 kg cada una.

Esto significa

1 bolsa = 50 kg de azúcar.

1 kg = 1000 gramos

50 kg = 50 × 1000 gramos

= 50000 gramos

Por tanto, 1 bolsa contiene = 50000 gramos de azúcar.

A partir de la pregunta anterior, se nos pregunta cuántas bolsas de azúcar obtendría si cada bolsa contuviera 250 gramos.

Por lo tanto:

50000/250 gramos

= 200 bolsas.

Por lo tanto, obtendría 200 bolsas.

Answer:

Step-by-step explanation:

The length of a rectangle is three times the width. The perimeter is 96 cm. Find the length and width of the rectangle.

Answers

Answer:

Length = 36cm

Width = 12 cm

Step-by-step explanation:

Perimeter = all the sides added up.

Perimeter of a rectangle = L + L + W + W OR  2L + 2W

We are given that the length = 3 times the width. So L = 3W

P = 2L + 2W

96 = 2 (3W) + 2W

96 = 6W +2W

96 = 8W (divide both sides by 8)

W = 12 cm

To find the length-  we know the length is 3 times the width.

So L = 3 x 12 = 36 cm

Step-by-step explanation:

Using the slope intercept form. The slop is 0

Answer: m = 0

Explanation: The equation y = 3 can be thought of as y = 0x + 3.

So our line has a slope of 0 and a y-intercept of 3.

When the equation of any line reads "y = a number",

it's graph will always be a flat or horizontal line.
