Answer:

the range for f(x) = (x-4) (x-2) is [-1,∞)

Step-by-step explanation:

all real numbers greater than or equal to -1

The range of the function is all real numbers greater than or equal to -1

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

Let the function be represented as A

Now , the value of A is

f ( x ) = ( x - 4 ) ( x - 2 )   be equation (1)

On simplifying , we get

f ( x ) = x ( x - 2 ) - 4 ( x - 2 )

f ( x ) = x² - 2x - 4x + 8

f ( x ) = x² - 6x + 8  

Now , the range of the function is set of possible y values

The vertex of the parabola is at ( 3 , -1 )

So , the range of the function is f ( x ) ≥ -1 and the interval is [ -1 , ∝ ]

Hence , the range of the function is f ( x ) ≥ -1

Answer:

Step-by-step explanation:

The domain of a function is the set for which the function is defined. Our function is the function [tex]h(x) = 6x-4[/tex]. This function is defined regardless of the value of x, so it is defined for every real value of x. That is, it's domain is the set {x|x is a real number}.

The range of the function is the set of all possible values that the function might take, that is {y|y=6x-4}. Recall that every real number y could be written of the form y=6x-4 for a particular x. So the range of the function is the set {y|y is a real number}.

Note that as x gets bigger, the value of 6x-4 gets also bigger, then it doesn't approach any particular number. Note also that as x approaches - infinity, the value of 6x-4 approaches also - infinity. In this case, we don't have any horizontal asymptote. Since the function is defined for every real number, it doesn't have any vertical asymptote. Since h is a linear function, it cannot have any oblique asymptote, then h doesn't have any asymptote.

Answer:

About 2.569 seconds

Step-by-step explanation:

To solve this problem, you can separate it into two half parabolas. The beginning part is initial upward rising. To calculate the amount of time that this part of the dive takes, you can use the formula [tex]v_f=v_o+at[/tex], where [tex]v_f[/tex] is the final velocity, [tex]v_o[/tex] is the initial velocity, a is the acceleration due to gravity, and t is the amount of time it takes. You know that the final velocity is 0, since the diver is reaching the terminal of their dive. Therefore, you can set up the following equation (assuming that the acceleration due to gravity is 32ft/s^2):

[tex]0=5+(-32)t[/tex]

[tex]t=5/32[/tex] seconds

To find the height that this indicates the diver has risen, you can plug this time into the following formula: [tex]d=v_o t+\frac{1}{2}at^2[/tex]

[tex]d=5(5/32)+\frac{1}{2}\cdot 32\cdot (5/32)^2\approx 1.172[/tex] feet

For the second part, you can use the equation [tex]d=v_o t+\frac{1}{2}at^2[/tex] again. Since the initial velocity for this part is 0, you can set up the following equation:

[tex]92+1.172=\frac{1}{2}\cdot 32 \cdot t^2[/tex]

[tex]t \approx 2.413[/tex]

Adding this to the time that the first part of the dive takes, you get a total of about 2.569 seconds. Hope this helps!

Answer: x = 13

Step-by-step explanation: When solving an equation like this, we are trying to get our variable which is our letter by itself.

So we first want to ask ourselves what is the 14 doing to x. Well, we can see that it's being added to x so to get x by itself, we will do the opposite of addition which is subtraction. So we subtract 14 from both sides of the equation.

The +14 -14 cancels out so we're left with x on the left.

On the right, we must subtract 14 from 27 to get 13.

So we have x = 13 which is the solution to this equation.

Answer:

[tex]x = 13[/tex]

Step-by-step explanation:

[tex]x + 14 = 27 \\ x = 27 - 14 \\ x = 13[/tex]

Answer:

Bronze

Step-by-step explanation:

To know the metal used to produce necklace, we must calculate the density of the necklace. This is illustrated below below:

Mass of necklace = 192g

Volume = 19.5cm^3

Density =...?

Density of a substance is simply defined as the mass of the substance per unit volume.

Density = Mass /volume

Density = 192g / 19.5cm^3

Density = 9.85g/cm^3

Now comparing the density of the necklace with the density of various metals in the table, we can see that the density of the necklace matches that of bronze.

Therefore, the necklace is made of bronze.

Answer:

14 inches

Step-by-step explanation:

Length of the hole = 16(½) inches

Length of the dirt = 8(¾)inches

The distance between the top of the pile to the bottom of the hole = ?

Since the dirt is beside the hole and not inside the hole, we can find it's length using addition.

Distance from the top to the bottom = length of dirt + length of the hole

Length of dirt = 8×¾ = 6 inches

Length of the hole = 16 × ½ = 8 inches

Distance from the top of the dirt to the bottom of the hole = (6 + 8) inches

Distance from the top of the dirt to the bottom of the hole = 14 inches

Note: the only way we can use subtraction here is if the hole was filled with dirt, what's the distance that's left

Distance left = length of hole - length of dirt

Distance left = 8 - 6 = 2 inches .

But what the question requested was the distance from the top of the dirt to the bottom of the hole

Every time, this second restaurant is less expensive; therefore, Lisa should decide to get pizzas for her group from the second restaurant.

All items and services purchased for resale of consumption throughout the production process are included in spending on goods and services, excluding capital goods whose consumption is recorded as consumption for fixed capital.

We have For the first restaurant

the total cost per pizza is $16 + $5 = $21.

For the second restaurant

the total cost per pizza is $17.

If Lisa purchases x pizzas,

the total cost from the first restaurant will be $21x + $5 = $21x + $5.

The total cost from the second restaurant will be $17x.

If x = 1, the first restaurant will cost $26 and the second restaurant will cost $17, so the second restaurant is cheaper.

If x = 2,

the first restaurant will cost $47 and the second restaurant will cost $34, so the second restaurant is cheaper.

If x = 3, the first restaurant will cost $68 and the second restaurant will cost $51, so the second restaurant is cheaper.

So, in every case, the second restaurant is cheaper, and Lisa should choose the second restaurant to purchase pizzas for her party.

Total distance traveled = 56 m

Total displacement is 12 m

Direction of coach is westward

Step-by-step explanation:

It is given that football coach first go 12 meter westward then 16 meter eastward.

So no position of coach in eastward direction = 16 - 12 = 4 m

And then 22 m west westward

Therefore position of coach now is 22-4 = 18 m westward

And finally 6 m eastward

Therefore final position of coach is 18-6= 12 m westward

So displacement of coach is 12 m and direction is westward.

Total distance traveled = 12+16+22+6= 56 m

Answer:

see below

Step-by-step explanation:

If the two angles form a straight angle, their sum is 180

2x+50  + 6x+2 = 180

Combine like terms

8x +52 = 180

Subtract 52 from each side

8x+52-52 = 180-52

8x =128

divide each side by 8

8x/8 = 128/8

x =16

2x+50 = 2(16)+50 = 32+50 = 82

6x+2 = 6(16)+2 =96+2 = 98

Answer:

The speed of the airplane was 800 mph and the wind, 480 mph.

Step-by-step explanation:

distance'd'/speed'v'=travel time't' and the distances are the same. The wind speed works against the plane upwind and helps the plane downwind, of course.

considering x=speed of airplane without wind

c=speed of wind

->Forward trip:

d/v=t

4800/(x-c)=15

320= x-c ---> eq(1)

->Return trip:

4800/(x+c)=10

480 = x+c --->eq(2)

Adding eq(1) and (2)

  x-c + x+c = 320+ 480

x= 800 mph

eq(1)=> 320= x-c

c= 800 - 320

c=480mph

The speed of the airplane was 800 mph and the wind, 480 mph.

Step-by-step explanation:

just did the T3ST :)

The equation that represents the quadratic regression is y = 3.06 + 0.33x + 2.09x².

To find the quadratic regression equation that fits these data:

First, we determined the following values,

mean of x = 0

mean of y = 17

the correlation coefficient r = 0.9960376489

The precise metric used in a correlation analysis to quantify the strength of the linear relationship between two variables is the correlation coefficient. In a correlation report, r stands for the coefficient.

A = 3.060606061

B = 0.3333333333

C = 2.090909091

And the quadratic regression can be modeled by the Quadratic regression: y=A+Bx+Cx².

Therefore, the equation is y = 3.06 + 0.33x + 2.09x².
