Answer:

[tex]f(x) = {x}^{2} - 13x + 30[/tex]

Step-by-step explanation:

A quadratic equation may be expressed as a product of the two binomials. The roots of the equations are 3 and 10, so the factors are (x-3) and (x-10).

f(x) = (x-3)(x-10)

f(x) = x^2 - 13x + 30

Answer:

515.5 mph

Step-by-step explanation:

I am fairly confident we are taking the same test/quiz thing right now and I figured this one out so here ya go:

60 degrees + 11 sec = 60.183 degrees

3960 * cos(60.183) = 1969       some number in relation to the distance to the poles

2 * pi * 1969 = 12371.8

12371.8 / 24 = 515.5mph

look up "How to Calculate Rotational Speed Around Earths Axis" on YT, video is by " VAM! Physics & Engineering" that is where I found the formula stuffs

Answer:

2 50ml bottles

Step-by-step explanation:

Reading through the question, we have:

For 80mL

[tex]C_1 = \pounds 55[/tex]

For 2 50mL bottles.

The cost is calculated by the original cost + half the original cost.

i.e.

[tex]C_2 = \pounds 45 + \frac{1}{2} * \pounds 45[/tex]

[tex]C_2 = \pounds 45 + \pounds 22.5[/tex]

[tex]C_2 = \pounds 67.5[/tex]

Next, is to calculate the unit price of each.

For 80mL

[tex]C_1 = \pounds 55[/tex]

[tex]Unit\ price = 55/80[/tex]

[tex]Unit\ price = 0.6875[/tex]

For 2 50mL bottles.

[tex]C_2 = \pounds 67.5[/tex]

[tex]Unit\ price - 67.5/(2 * 50)[/tex]

[tex]Unit\ price = 67.5/100[/tex]

[tex]Unit\ price = 0.675[/tex]

By comparison, the 2 50mL is the best buy because it has smaller unit price

Answer:

2x² - 7x - 15

Step-by-step explanation:

Given

(2x + 3)(x - 5)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(x - 5) + 3(x - 5) ← distribute parenthesis

= 2x² - 10x + 3x - 15 ← collect like terms

= 2x² - 7x - 15

minimum is: (8,5)

36-4+1         32+1     31

i hope this helps you!

Answer:

The answer is 9.

Step-by-step explanation:

Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.

1. Plug in X: 3(2)^2 -2(2) + 1

2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1

3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1

4. Addition: -4 + 1 = -3, so it is now 12-3

5. Subtraction: 12-3 = 9, so the answer is 9!

I hope this helps.

Answer:

21 x 21 = 441

Step-by-step explanation:

Whenever there is an exponent that is the many times you multiply the base by itself to.

Power is the result of multiplying two numbers together. The value of 21^2 is 441.

Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.

Given that 21 has a power of 2, therefore, 21 to the power 2 means that 2 should be multiplied by itself twice.

21^2

= 21²

= 21 × 21

= 441

Hence, the value of 21^2 is 441.

Answer:

9:3

Step-by-step explanation:

Please find attached the information required to answer this question

From the upper right corner, there are 8 people who do not like reading.

On the lower right corner of the table, there is 1 one person who does not like reading and playing video games

On the lower left corner, there are two people who do not like playing video games.

The total number of people who do not like reading = 8 + 1 = 9

The total number of people who do not like playing video games = 2 + 1 = 3

= 9 : 3

Answer:

A. 38°

Step-by-step explanation:

angle of tangents of circle = (Bigger arc - smaller arc) / 2

x = (218 - 142) / 2 = 76 /2 = 38°

Step-by-step explanation:

The equation is given as;

−4(x−3)=20

Gwendolyn's flaw is in the following lines;

−4x + 12 = 20

−4x = 32

When collecting like terms, the moment 12 crosses over, it becomes - 12 and not + 12

The correct solution is given as follows;

Step 1: Expand the brackets

This results to;

- 4x - (-4 * 3) = 20

-4x + 12 = 20

Step 2: Collect like terms

This results to;

- 4x = 20 - 12

- 4x = 8

Step 3: Solve for x

x = 8 / (-4)

x = -2

8x - 10 = 70

8x = 70 + 10

8x = 80 / : 8

x = 10

Answer:

x = 180

∠DBC = 23

∠ABC = 157

Step-by-step explanation:

A straight line is always 180 degrees

A to D line = 180

6x + 19 + x = 180

7x + 19 = 180

      -19     -19

7x = 161

/ 7     / 7

161 /7 = 23

x = 23

Then plug it in

6x + 19

6 ( 23 ) + 19 = 157

x

x = 23

Answer:

Step-by-step explanation:

3/4*8=6

The requried number of Ruth filled with soda is 6 cups.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,

To find the number of cups Ruth filled with soda, we need to divide the amount of soda she poured into cups by the amount of soda in each cup.

Ruth poured 1/8 liter of soda into cups. To convert this to cups, we need to know that 1 liter is equal to 4 cups. So, 1/8 liter is equal to:

(1/8) x 4 cups = 0.5 cups

Ruth has 3/4 liters of soda in her refrigerator, which is equal to:

(3/4) x 4 cups = 3 cups

So, the number of cups Ruth filled with soda is:

= 3 / 0.5
= 6 cups

Thus, the requried number of Ruth filled with soda is 6 cups.
