can anyone hknow number 2?

Answer:

[tex]x = 8 \\ x = - 9[/tex]

Step-by-step explanation:

[tex]2 {x}^{2} + 2x - 144 = 0 \\ 2 {x}^{2} + 18x - 16x - 144 = 0 \\ 2x(x + 9) - 16(x + 9) = 0 \\ (2x - 16)(x + 9) = 0 \\ \\ 2x - 16 = 0 \\ 2x = 0 + 16 \\ 2x = 16 \\ \frac{2x}{2} = \frac{16}{2} \\ x = 8 \\ \\ x + 9 = 0 \\ x = 0 - 9 \\ x = - 9[/tex]

Answer:

g= L/(T/2π)²

Step-by-step explanation:

To solve for L in the equation T=2π√L/g, we square both sides to get T² = 4π²L/g. Then, multiplying both sides by g gives gT² = 4π²L. Finally, dividing by 4π² gives the rearranged formula L = gT²/(4π²).

The initial formula T=2π√L/g denotes the period of one swing of a simple pendulum, where T is the period, L is the length of the string, and g is the acceleration due to gravity. To solve for L, we first need to square both sides of the equation to get rid of the square root, resulting in T² = 4π²L/g. Then we multiply both sides by g to get gT² = 4π²L. Finally, we divide both sides by 4π² to solve for L: L = gT²/(4π²). This is the rearranged formula to solve for the length of the pendulum in terms of π, T, and g.

Answer:

median = 5

Step-by-step explanation:

The median is the middle value of the data arranged in ascending order. If there is no exact value in the middle then it is the average of the 2 values on either side, that is

3  ,   3  ,  5  ,   5  ,   7  ,   9

                   ↑ middle

median = [tex]\frac{5+5}{2}[/tex] = [tex]\frac{10}2}[/tex] = 5

Answer:

The median is 5.

Step-by-step explanation:

First we must arrange them in order.

3, 3, 5, 5, 7, 9

we must cross out the numbers to find the middle number so,

we cross the beginning and last number which in this is case is 3 and 9

3, 5, 5, 7

we must do the same thing we did so in this case the beginning is 3 and 7 is the end so we must cross them out

5,5

we have two numbers and no number in the middle

in this case we add the 2 numbers together so,

5 + 5 = 10

then we must divide the answer by 2

10/2 = 5

So, the median is 5

Hope this helps :)

Answer:

25%

Step-by-step explanation:

$122.80 + $40.94 = $163.74

$163.74 - 25% = $122.80

Answer:

The answer is C

Step-by-step explanation:

122.80 plus 40.94 equals 163.74

163.74 subtract 25% equals 122.80

The expression equivalent to (25x - 10y) is (5(20x - 10y)) thus option D, is correct.

To determine the equivalent expression, we can use the distributive property, which states that (a(b + c) = ab + ac). In this case, option D,(5(20x - 10y)), applies the distributive property by multiplying 5 to both terms within the parentheses. The result is [tex]\(5 \times 20x - 5 \times 10y\)[/tex], which simplifies to (100x - 50y). Therefore, option D is equivalent to (25x - 10y).

Understanding the distributive property is fundamental in algebraic simplification. When applying the distributive property to option D, each term inside the parentheses is multiplied by 5, resulting in the expression (100x - 50y). This matches the given expression (25x - 10y), confirming that option D is the correct equivalent expression.

Recognizing and using algebraic properties, such as the distributive property, is crucial for simplifying expressions and identifying equivalent forms. In this case, option D accurately represents the given expression in a different but equivalent form, providing a valuable tool for algebraic manipulation and problem-solving in mathematics.

Final answer:

The expression that is equivalent to 25x – 10y is 5(5x – 2y), where 5 is factored out as the greatest common factor.

(Option A)

Explanation:

The expression equivalent to 25x – 10y can be found by factoring the greatest common factor out of each term. Looking at 25x and -10y, the largest number that divides both 25 and 10 is 5. Factoring a 5 out of each term, we get 5(5x – 2y). Hence, the equivalent expression is 5(5x – 2y).

So, the answer to the question is:

The factored expression, 5(5x – 2y), is the result of extracting the greatest common factor from 25x – 10y. This simplified form is equivalent to the original expression and confirms that option A, 5(5x – 2y), is the correct answer.

After calculating the unit rates and applying the given code, the final answer to the puzzle is 12.

The puzzle involves analyzing the unit rates of different line graphs and then performing a specified mathematical operation on them using a given code.

Calculate the unit rates for each graph:

Graph A: 8/4 = 2

Graph B: -6/3 = -2

Graph C: 10/5 = 2

Graph D: -8/4 = -2

Graph E: 8/4 = 2

Graph F: -6/-3 = 2

Area of bigger circle = 36.32cm²

Step-by-step explanation:

Kindly find attached rough sketch for your reference

This problem bothers on the mensuration of flat shapes, a circle

Kindly find attached

Given data

Area of small circle =9cm³

Say we assume the all unit is in cm

From the diagram we can see that the diameter of the small circle is the radius of the bigger circle

So let us solve for the diameter of the small circle

9= πr²

r²=9/3.142

r²= 2.86

r=√2.86

r= 1.7cm

But diameter of small circle

d= 2r

d= 1.7*2= 3.4cm

Hence the radius of the bigger circle is 3.4cm

Area of bigger circle =πr²

=3.142*3.4²

=3.142*11.56

Area of bigger circle = 36.32cm²

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

V is the midpoint of QS and W is the midpoint of RS.

Now,

Since, V is the midpoint of QS and W is the midpoint of RS.

Hence, We get;

⇒ QV = VS

And, RW = WS

Cleary, Triangle QRS and Δ VWS are congruent.

Hence, We can formulate by the definition of proportional;

⇒ VS / QS = VW / QR

Substitute all the values, we get;

⇒ 2a / 4a = (2a - 2) / (3a + 6)

⇒ 1/2 = (2a - 2) / (3a + 6)

⇒ 3a + 6 = 2 (2a - 2)

⇒ 3a + 6 = 4a - 4

⇒ 6 + 4 = 4a - 3a

⇒ 10 = a

⇒ a = 10

Thus, The value of length VS = 2a

                                             = 2 × 10

                                             = 20 units

Therefore, The length of VS will be 20 units.

Step-by-step explanation:

The cost to rent each chair is $1.5 and each table is $6.

To solve this problem, let's denote the cost of renting one chair as C and one table as T.

From the given information, we can set up a system of equations:

1. 8C + 3T = 30 (for the first scenario with 8 chairs and 3 tables)

2. 2C + 5T = 33 (for the second scenario with 2 chairs and 5 tables)

Use the elimination method.

First, multiply equation 1 by 2 and equation 2 by 8 to eliminate C:

1. 16C + 6T = 60

2. 16C + 40T = 264

Now, subtract equation 1 from equation 2:

(16C + 40T) - (16C + 6T) = 264 - 60

34T = 204

Now, divide both sides by 34:

T = 204 / 34 = 6

Now, we have found that the cost to rent one table is $6.

Substitute T = 6 into equation 1:

8C + 3(6) = 30

8C + 18 = 30

8C = 30 - 18

8C = 12

C = 12 / 8

= 1.5

Therefore, the cost to rent one chair is $1.5.

Therefore, the cost to rent each chair is $1.5 and each table is $6.

Answer:

x = 58

Step-by-step explanation:

We can use algebra to solve this one! Since <FAE + <FA= 180 we can write :

x + 7 + 2x -1 = 180

Let's simplify the left side to :

3x + 6 = 180

Subtract 6 to isolate the variable.

3x = 174

Divide both sides by 3 to get

x = 58
