The parent function f(x)=√x is transformed to g(x) = f(-x) - 2. Which graph represents g(x)?

Answer:

72

Step-by-step explanation:

8 x 3² = 8 x 3 x 3

          = 8 x 9

          = 72

[P.S. If you meant (8 x 3)² the answer is:

(8 x 3)² = (24)²

            = 24 x 24

            = 576     ]  

In the equation given, the quadratic inequality  that shows the relationship above is: option B. y ≥ 0.2(x + 4)(x - 10).

Note that a quadratic function exist in factored form is as:

y = a(x - a)(x - b)

The zeros of the equation is seen at x = (-4, 10)

Therefore, one need to write an expression for the quadratic inequality and so it will be:

y ≥ a(x - a)(x - b)    

Also note that at At point (6, -8), we also have:

-8 = a(6 - (-4))(6 - 10)  

-8 = a(6 + 4)(6 - 10)

-8 = a(10)(-4)

-8 = -a(40)

a = 0.2.

Therefore, In the equation given, the quadratic inequality  that shows the relationship above is: option B. y ≥ 0.2(x + 4)(x - 10).

Answer:

N: 30 B:150

Step-by-step explanation:

Supplementary angles add up to 180 meaning their equations must also add up to 180:

(3x + 18) + (2x + 142) = 180

Solve for x:

5x + 160 = 180

5x = 20

x = 4

Substitute 4 in all values of x to obtain the measure of the two angles:

N: 3(4) + 18 = 30

B: 2(4) + 142 = 150

This result is approximate.

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

Explanation:

mu = 750 = mean

sigma = 75 = standard deviation

The raw scores or x values are x = 750 and x = 825

Let's compute the z score for each x value

z = (x - mu)/sigma

z = (750 - 750)/75

z = 0

and

z = (x - mu)/sigma

z = (825 - 750)/75

z = 1

Therefore P(750 ≤ x ≤ 825) is equivalent to P(0 ≤ z ≤ 1) in this context.

Use a z score table to determine that

P(z ≤ 0) = 0.5

P(z ≤ 1) = 0.84314 approximately

So,

P(a ≤ z ≤ b) = P(z ≤ b) - P(z ≤ a)

P(0 ≤ z ≤ 1) = P(z ≤ 1) - P(z ≤ 0)

P(0 ≤ z ≤ 1) = 0.84314 - 0.5

P(0 ≤ z ≤ 1) = 0.34314 approximately

The value 0.34314 then converts to 34.314% which rounds to 34%

Or you could use the empirical rule as shown below. The pink section on the right is marked 34% which is approximate. This pink section is between z = 0 and z = 1.

The true statement is h(2)=16.

The domain of a function is the set of values that we are allowed to plug into our function. The range of a function is the set of values that the function assumes.

Given:

domain of -3 ≤ x ≤ 11 and a range of 1 ≤ h(x) ≤ 25,

Also, h(8) = 19 and h(-2) = 2,

Now,

2=h(-2)< h(2)<h(8) =19

h(8)=19≠21

h(13)> h(8) =19

h(-3)< h(-2) =2  [1 ≤ h(x) ≤ 25]

Hence, h(2)=16

A function assigns the values. The half life of the substance is 6.25 days.

A function assigns the value of each element of one set to the other specific element of another set.

Given the function for the substance as [tex]N= N_o e^{-kt}[/tex], therefore, the half life of the substance can be written as,

[tex]N= N_o e^{-kt}\\\\\dfrac{N}{N_o}= e^{-kt}[/tex]

Since we need to find the half life, therefore, the ratio of the initial mass and the mass after half-life will be 1/2.

[tex]\dfrac12= e^{-kt}\\\\\ln (0.5) = -kt[/tex]

Given the value of k is 0.1109, therefore,

[tex]\ln (0.5) = -kt\\\\\ln (0.5) = -(0.1109)t\\\\t = 6.25[/tex]

Answer:

y = 5x - 6

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 5 and c = - 6 , then

y = 5x - 6 ← equation of line

The equation represents a linear function with a slope of 5 and a y-intercept of -6 is y = 5x - 6.

The equation of a linear function is typically written in the form "y = mx + b," where "m" represents the slope and "b" represents the y-intercept.

Given that the slope is 5 and the y-intercept is -6, the equation becomes:

y = 5x - 6

Here's the calculation:

The slope (m) is 5, and the y-intercept (b) is -6. Therefore, the equation becomes:

y = 5x - 6

This equation represents a linear function with a slope of 5 and a y-intercept of -6.

Hence the equation represents a linear function with a slope of 5 and a y-intercept of -6 is y = 5x - 6.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

Given the cost price of all the fishing rods is $23,000, also the selling price of all the fishing rod is $49,000. Therefore, the total profit from this transaction is,

Profit = $49,000 - $23,000 = $26,000

Since the profit on a single fishing rod is $250, while the total profit is $26,000. Therefore, the number of fishing rods can be written as,

Number of Fishing rod = Total profit/ Profit per rod

                                      = $26,000 / $250

Let the age of Clayman be x

Let the age of Ato be y

If the sum of ages of Clayman and Ato is 25 years. then;

x + y = 25

x = 25 - y ...... 1

In five years time;

Age of Clayman = x + 5

Age of Ato = y + 5

If in five years' time, the age of Ato will twice the age of Clayman now, then;

y+5 = 2x ............. 2

Substitute equation 1 into 2

y +5 = 2(25-y)

y + 5 = 2(30 - y)

y + 5 = 50 - 2y

3y = 45

y = 15
