Alright,Alex let say we have factored a quadratic into two binomial, for example

[tex](5x + 3)(6x - 4)[/tex]

If we set both of those equal to zero

[tex](5x + 3)(6x + 4) = 0[/tex]

We can used the zero product property in this case to find the roots of the quadratic equation.

This means that

[tex]if \: ab = 0 \: then \: a = 0 \: and \: b = 0[/tex]

This means we set each binomal equal to zero to find it root.

[tex]5x + 3 = 0[/tex]

[tex]5x = - 3[/tex]

[tex]x = - \frac{3}{5} [/tex]

[tex]6x + 4 = 0[/tex]

[tex]6x = - 4[/tex]

[tex]x = - \frac{2}{3} [/tex]

So our roots are negative 3/5 and negative 2/3 using zero product property

Is a triangle with side lengths of 5, 10, and 15 a right triangle? Explain

Answers

Answer:

No, it is not a right triangle.

Step-by-step explanation:

Using the property of the right triangle, square root (5^2 + 10^2) = 5root(5), and it is not equal to 15, so it is not a right triangle.

If triangle is a right triangle we can use Pythagorean theorem, c^2=a^2+b^2
c=15, a=5, b=10
15^2=5^2+10^2
225=25+100
225=125
225 is not equal to 125 therefore, this triangle is not a right triangle.

Allison has a loyalty card good for a discount at her local hardware store. The item she wants to buy is priced at $36, before discount and tax. After the discount, and before tax, the price is $30.96. Find the percent discount.

Answers

Answer:

14%

Step-by-step explanation:

Original price of item = $36

Price after discount = $30.96

Percentage discount = x

To get the percent discount

x = 36 - 30.96/36

x = 5.06/36

x = 0.14

Percentage discount = 0.14 % 100

Percentage discount = 14%

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures cell phones, can be modeled by the polynomial 2x2 + 55x + 10. The cost, in dollars, of producing the cell phones can be modeled by 2x2 – 15x – 40. The variable x represents the number of cell phones sold.

What expression represents the profit, and what is the profit if 240 cell phones are sold?

40x – 30; $2,400
40x – 30; $9,570
70x + 50; $16, 850
70x + 50; $28,800

Answers

Answer:

Given that the equation of the revenue is R=2x2+55x+10 and the equation of the cost is C=2x2 – 15x – 40, you will get the profit by subtracting the revenue from the cost: R-C=P. Therefore, P=(2x2+55x+10)-(2x2 – 15x – 40). You will get P=70x+50 where x is is the number of cellphones sold. If 240 cellphones are sold, then the profit is 16850 dollars.

Step-by-step explanation:

The profit expression is 70x + 50 and the profit if 240 cell phones are sold is $16,850

How to calculate profit

Revenue, R = 2x² + 55x + 10Cost, C = 2x² – 15x – 40

where,

x = number of cell phones sold.

Profit = Revenue - cost

= (2x² + 55x + 10) - (2x² – 15x – 40)

= 2x² + 55x + 10 - 2x² + 15x + 40

Profit = 70x + 50

If x = 240

Profit = 70x + 50

= 70(240) + 50

= 16,800 + 50

= $16,850

Answer:

Option B

Step-by-step explanation:

Volume of a cube is:

[tex]A = s^3[/tex]

s - side length

All sides are the same length in a cube.

We are given the information that the total volume of the cube is 10 cubic feet.

[tex]10=s^3\\\\\sqrt[3]{10}=\sqrt[3]{s^3}\\\\\boxed{2.154435... = s}[/tex]

2.154435... ≈ 2.15

The approximate height of the cube is 2.15 inches.

Since the height of the shelf is 24 inches tall, the cube should be able to fit.

2.15 < 24

Option B should be the correct answer.

Triangle XYZ is shown on the coordinate plane below:
If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?

Answers

Answer:

Step-by-step explanation:

Triangle XYZ has been reflected across a line y = 1,

Therefore, line y = 1 will work like a mirror and all the distance of the points of the points from this line will be equal after the reflection about this line.

Distance of X from this line = 2 units

After reflection distance of X' from the line of reflection will be 2 units in opposite side.

Therefore, coordinates of X' will be (3, 3)
