Using graph paper, solve the following inequality. Then click on the graph until the correct one is displayed. y ≥ |x - 1|

The expression [tex] x^3y [/tex] means that you have to cube the value of [tex] x [/tex] and multiply it by the value of [tex] y [/tex].

So, the value of [tex] x [/tex] is 5, which becomes 125 when cubed. When we multiply it by the value of [tex] y [/tex], which is 10, the result is 1250:

[tex] x^3y = 5^3\cdot 10 = 125\cdot 10 = 1250 [/tex]

The value of the expression x^3 * y^1 * x^3 * y^1 when x = 5 and y = 10 is 156250.

Let's substitute the values of x and y into the expression:

x^3 * y^1 * x^3 * y^1

When x = 5 and y = 10:

(5^3) * (10^1) * (5^3) * (10^1)

Now, calculate the values:

(5^3) = 5 * 5 * 5 = 125

(10^1) = 10

Now, plug these values back into the expression:

125 * 10 * 125 * 10

Multiply the numbers:

125 * 10 * 125 * 10 = 156250

So, the value of the expression x^3 * y^1 * x^3 * y^1 when x = 5 and y = 10 is 156250.

Answer:

24

Step-by-step explanation:

We want the ratios to be equal

18:x    9:12

18                 9

--------- =   -----------

x                  12

We divide by 2 to get from 18 to 9

x ÷2 =12

Multiply each side by 2

x ÷2*2 =12*2

x = 24

18:24    9:12

Answer:

24 is your answer

Step-by-step explanation:

18 : x = 9 : 12

You are solving for x. First, simplify the ratio on the right side.

(9/3) : (12/3) = 3 : 4

Next, solve for x. Multiply. Remember that what you do to the numerator, you do to the denominator.

3 : 4 = 18 : x

3 (6) : 4 (6) = 18 : x

Simplify

18 : 24 = 18 : x

x = 24

Answer:2 pi

Step-by-step explanation:

Answer:

   = -sqrt(2)

Step-by-step explanation:

tan theta = -1

we know tan = opposite/ adjacent

So opposite/adjacent = -1

Multiply by adjacent on each side

opposite = - adjacent

We also know from pythagorean theorem that

opposite ^2 + adjacent ^2 = hypotenuse ^2

Substituting in for adjacent

opposite ^2 + (-opposite ) ^2 = hypotenuse ^2

opposite ^2 + opposite ^2 = hypotenuse ^2

2 opposite ^2 = hypotenuse ^2

 Taking the square root on each side

sqrt(2 opposite ^2)   =  sqrt(hypotenuse ^2)

sqrt(2) opposite = hypotenuse

We are now set to find the sec

sec theta = hypotenuse / adjacent

               = sqrt(2) opposite/ adjacent

Replace the opposite = -adjacent

                 = sqrt(2) (-adjacent)/adjacent)

                 = -sqrt(2)

The value of secθ for 3π/ 2 < θ< 2π is √2. This is because tanθ is negative in Quadrant III and sec²θ = 1 + tan²θ. Therefore, secθ = √2.

Step 1: Determine the quadrant of θ

We know that 3π/ 2 < θ< 2π, which means that θ is in Quadrant III. In Quadrant III, tanθ is negative and secθ is positive.

Step 2: Use the identity sec²θ = 1 + tan²θ to solve for secθ

The identity sec²θ = 1 + tan²θ can be used to solve for secθ given tanθ. Substituting tanθ = -1 into the identity, we get:

sec²θ = 1 + (-1)² = 2

Taking the square root of both sides, we get:

secθ = √2

Therefore, the value of secθ for 3π/ 2 < θ< 2π is √2.

Subtract 40 from each side

x^2 + 6x -40 =0

Factor,  what 2 numbers multiply to -40 and add to 6

10 * -4 = -40    10+-4 = 6

(x+10) (x-4) = 0

Using the zero product property

x=-10    x=4

Answer:

x = −10 and x = 4

Step-by-step explanation:

We are given the following quadratic equation and we are to solve it to find the two solution for the variable x:

[tex]x^2+6x=40[/tex]

Rearranging the equation by putting the constant on the same side as the variables to get:

[tex]x^{2} +6x-40=0[/tex]

Step-by-step explanation:

The distribution of sample means has a standard deviation that is the pipe standard deviation divided by the square root of the sample size. Thus, the standard deviation of the sample mean is 0.003/√9 = 0.001.

Then the limits on sample mean are 1.010 - 1×0.001 = 1.009 and 1.010 +2×0.001 = 1.012. The proportion of the normal distribution that lies between -1 and +2 standard deviations is about 81.9%.

The problem involves statistical calculation involving mean, standard deviation, and Z-scores of a normal distribution. We first calculate sample standard deviation, then the Z-scores for the given range. After finding probabilities for the Z-scores, we subtract to get the final probability of 0.8185.

Evaluating functions is the process of substituting a specific value in place of the variable in a function to compute a result. For example, given the function f(x) = x^2, if asked to find f(2), you would replace x with 2 resulting in 4.

Evaluating functions in mathematics involves inserting a specific numerical value or a variable into a function to compute a result. For example, if you're given the function f(x) = x^2, and you're asked to find f(2), you simply substitute 2 in place of x in the function, resulting in 2^2, which equals 4.

For instance, if we were to evaluate f(5) for the given function, it would give the result 25 because 5^2 = 25. Hence, simply put, to evaluate a function is to replace the variable with the input value, and compute the result.

Answer:

This question is not as hard as it seems.

Let the first number = x.

The other number will be x - 16.

The sum of both the number is 52.

So, x+x-16 = 52

Which would simplify to 2x -16 = 52.

When I add 16 to both sides, it would give me 2x = 68.

Then, divide both sides by 2.

This leaves us with x = 34.

Since we have x, now x-16 would be 34-16 = 18.

The two numbers are 34 and 18, this answer is correct because both of them add up to give me 52.
