Solve the problem below. Write the answer in the space provided.

1/2 of 4 feet = ___________
inches

Answer:

(-1 + √2) and (-1 - √2)  

Step-by-step explanation:

Given in the question the equation

y = x² + 2x - 1

To find the x-intercept, substitute in 0 for y

0 = x² + 2x - 1

To find value of x use quadratic equation

x = -b ± √b²-4ac / 2a

  here a = 1

           b = 2

           c = -1

x1 = -2 + √2²-4(1)(-1) / 2(1)

   = -2 + 2√2 / 2

   = -1 + √2  

x2 = -2 - √2²-4(1)(-1) / 2(-1)

   = -2 - 2√2 / -2

   = -1 - √2  

To simplify 16m^2/24m^7, you divide both numbers by 8 and subtract the exponents, getting 2/3m^(-5), which is then rewritten with positive exponents as 2/(3m^5).

To simplify the expression 16m^2/24m^7, we need to reduce the fraction by dividing both the numerator and the denominator by their greatest common factor. Additionally, we apply the laws of exponents to simplify the expression further.

First, we observe that 16 and 24 have a common factor of 8. So we divide both by 8:

16 / 8 = 2
24 / 8 = 3

Now our expression looks like this:

2m^2 / 3m^7

Next, we apply the laws of exponents. Since both the numerator and denominator have the base m, we subtract the exponent in the numerator from the exponent in the denominator:

m^2 / m^7 = m^(2-7) = m^(-5)

Combining the reduced coefficients and the exponents, we get:

2/3m^(-5)

To have positive exponents, we can write:

2/(3m^5)

                                =        96            +     168    +  280

                                =  544

Answer: third option

Step-by-step explanation:

To solve the problem you must apply the proccedure shown below:

- Descompose the numerator and the denominator of the given fraction into its prime numbers:

[tex]64=2*2*2*2*2*2\\144=2*2*2*2*3*3[/tex]

Then you can rewrite:

[tex]64=2^6\\144=2^4*3^2[/tex]

Then:

[tex]\±\sqrt{\frac{{2^6}}{{2^4*3^2}}}=\±\frac{2^3}{2^2*3}=\±\frac{8}{4*3}=\±\frac{8}{12}[/tex]

Therefore, the answer is: [tex]-\frac{8}{12}\ and\ \frac{8}{12}[/tex]

Answer:

The correct answer is option 3

-8/12 and 8/12

Step-by-step explanation:

It is given that square roots of 64/144

The given number is a fraction.

The numerator of  the square root and denominator both are perfect squares. So it is easy to find the square root of given number

To find the square root of 64/144

we have , √64 = ±8 and 144 = ±12

√(64/144) = ± 8/12

Therefore, √(64/144) = 8/12 or √(64/144) = -8/12

Therefore the correct answer is option 3

Answer:

First figure

Step-by-step explanation:

From given graph we can see that the point (3,0) and (3,1) lie on the given graph.

90 degree rotation counterclockwise around origin:The point (x,y) is rotated 90 degree counterclockwise about origin then the point changed by the rule

[tex](x,y)\rightarrow(-y,x)[/tex]

When the point (x,y) is reflected across x- axis then point is transformed   by the rule

[tex](x,y)\rightarrow (x,-y)[/tex]

Point (3,0) is rotates 90 degree counter clockwise about origin then the point will be (0,3) after rotation.

When the point (0,3) is reflected across x- axis then the point becomes

(0,-3).

The point (3,1) becomes (-1,3) after 90 degree counterclockwise rotation.

After reflection across x- axis, the point becomes (-1,-3)

(0,-3) and (-1,-3) lie in the firs figure.

Hence, it is true.

Answer:

The total weight of the bowling ball in ounces is 173 ounces

Step-by-step explanation:

To find this, first change the pounds to ounces by multiplying by 16.

10lbs * 16 = 160 ounces

Now add the ounces to that.

160 + 13 = 173 ounces

The total weight of Nene's bowling ball is 10.8125 pounds, after converting 13 ounces to pounds (since there are 16 ounces in 1 pound) and adding it to the 10 pounds.

To find the total weight of Nene's new bowling ball, we must first recognize that the weight is given in two different units: pounds and ounces. There are 16 ounces in 1 pound.

Step 1: Identify the weight in pounds and ounces.

Weight in pounds: 10 pounds

Weight in ounces: 13 ounces

Step 2: Convert the ounces to pounds. Since there are 16 ounces in 1 pound, we divide 13 ounces by 16 to get the weight in pounds.

13 ounces / 16 = 0.8125 pounds

Step 3: Add the weights to get the total weight in pounds.

10 pounds + 0.8125 pounds = 10.8125 pounds

Therefore, the total weight of the bowling ball is 10.8125 pounds.

The product of √3 and √2 is √6, which is an irrational number. Thus, the expression represents the product of two irrational numbers resulting in an irrational number. The correct answer is option B.

To solve the question about the expression √3 · √2, we need to consider both the nature of the numbers involved and the result of their multiplication.

First, know that both √3 and √2 are irrational numbers. An irrational number cannot be expressed as a simple fraction, which is the case for both of these numbers.

When multiplying two irrational numbers, the result can be rational or irrational depending on the values involved. However, in this case:

Since √6 is not a perfect square and cannot be simplified to a rational number, it is also irrational.

Therefore, the correct answer is: B. It represents the product of two irrational numbers and is equivalent to an irrational number.

The measure of side length x to the nearest tenth is approximately 2879.4 meters.

The figure in the image is a right triangle.

From the figure;

Angle θ is the complement of the given angle.

Ange θ = 90 - 10 = 80 degrees

Adjacent to angle θ = 500 m

Hypotenuse = x

To solve for the hypotenuse of the right triangle, we use the trigonometric ratio:

Note that;

cosine = adjacent / hypotenuse

Hence;

cos( θ ) = adjacent / hypotenuse

Plug in the values:

cos( 80 ) = 500 / x

Solve for x:

x × cos( 80 ) = 500

x = 500 / cos( 80 )

x = 2879.4 m

Tina's mum and Vida's mum cooked a total of 70 dishes together by adding the 50 dishes cooked by Tina's mum to the 20 dishes cooked by Vida's mum.

The question you've asked relates to simple addition, which is a basic arithmetic operation. To find out how many dishes Tina's mum and Vida's mum cooked altogether, we simply add the two numbers together:

Number of dishes Tina's mum cooked = 50

Number of dishes Vida's mum cooked = 20

Total number of dishes cooked = 50 (Tina's mum) + 20 (Vida's mum) = 70 dishes

So, Tina's mum and Vida's mum cooked 70 dishes in total.

Answer:

The range of the graph is all real numbers greater than or equal to 0.

Step-by-step explanation:

Consider the provided function [tex]f(x)=\sqrt{x}[/tex].

Domain of the function is the set of all possible x values which a function can take.

Range of the function is the set of all output values or the values produced by the function.

Now, consider the provided function.

The value of x can not be a negative number because the square root of negative number is not a real number.

Thus, the domain of the function must be zero or greater than zero.

The graph of the function is shown in figure 1.

From the graph it can be observed that the values produced by that function is all real numbers greater than or equal to 0.

Therefore, the required answer is: The range of the graph is all real numbers greater than or equal to 0.

Answer:

y = (-1)*2^(x + 1)

Step-by-step explanation:

This one is not a line. It is something raised to a power. In addition, there is an ugly minus sign somewhere.

First of all, every answer is some sort of power of 2. All of them are 2^x but we don't exactly know how x words. It is not a simple y = 2^x because the first one is - 4 not - 2.

So there is an extra power somehow.

Try

y = 2^(x + 1) That looks promising

x = 1

y = 2^(1 + 1)

y = 2^2

y = 4

===============

Try another one

x = 2

y = 2^(2 + 1)

y = 2^3

y = 8

==============

I think you'll find that the other two are well behaved. and come to the answer (except for the minus) as they should.

What about that minus.

y = (-1)*2^(x + 1) should give a minus y value for any term.

They will have $16.75 left.

There are many methods of doing this. This one finds the median; however, instead of halving, you can use quarters instead.

First order the data, ascendingly:

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

Find the median:

For an even number of values: The number of values / 2

For an odd number of values: The number of values + 1 / 2

11 is odd.

11 + 1 / 2

12 / 2 = 6

The median is at the 6th position.

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

The median is 20.

Other method:

You don't need this step.

Using the values lower than the median, exclusive, find the median of the lower values;

For an odd number of values: The number of values + 1 / 2

10, 17, 18, 18, 18

5 + 1 / 2 = 6 / 2 = 3

The median of the lower values is at position 3.

This is the lower quartile.

10, 17, 18, 18, 18

Other method:

For an odd number of values: The number of values + 1 / 4

11 + 1 / 4 = 12 / 4 = 3

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

Using the values greater than the median, exclusive, find the median:

For an odd number of values: The number of values + 1 / 2

20, 25, 25, 30, 30

5 + 1 / 2 = 6 / 2 = 3

The median of the upper values is at position 3.

20, 25, 25, 30, 30

This is 25.

This is the upper quartile.

Other method:

For an odd number of values: (The number of values + 1 / 4) * 3

(11 + 1 / 4) * 3 = (12 / 4)  * 3 = 3 * 3 = 9

10, 17, 18, 18, 18, 20, 20, 25, 25, 30, 30

Your interquartile range is 3 - 25

25 - 3 = 21

20x^4-39x^3-16x

Make sure to multiply all the terms by each other in the two parentheses

To multiply the given expressions (5x^2-6x+2)(4x^2-3x), we use the distributive property. The resulting expression is 20x^4 - 39x^3 + 18x^2.

To multiply the given expressions (5x^2-6x+2)(4x^2-3x), we can use the distributive property of multiplication. We multiply each term in the first expression by each term in the second expression and then simplify the resulting terms by combining like terms.

First, let's multiply the first terms: 5x^2 * 4x^2 = 20x^4.

Next, let's multiply the outer terms: 5x^2 * -3x = -15x^3.

Then, let's multiply the inner terms: -6x * 4x^2 = -24x^3.

Finally, let's multiply the last terms: -6x * -3x = 18x^2.

Now, let's combine all the resulting terms together: 20x^4 - 15x^3 - 24x^3 + 18x^2 = 20x^4 - 39x^3 + 18x^2.
