The domain of the function 3x² + 6x – 8 is a real number and the range of the function 3x² + 6x – 8 will be (-11, ∞).

The domain means all the possible values of the x and the range means all the possible values of the y.

The function is given below.

f(x) = 3x² + 6x – 8

The range of the function will be

f(x) = 3x² + 6x – 8

f(x) = 3x² + 6x + 3 – 11

f(x) = 3(x² + 2x + 1) – 11

f(x) = 3(x + 1)² – 11

Then the range of the function will be from -11 to infinity.

More about the domain and range link is given below.

Answer:

$172.80

Step-by-step explanation:

The phone cost $800

Decreases by 2/5 every year. So the cost would be 3/5 (instead of doing 800 - 800 *2/5 its easier to just do 800*3/5)

Here is a equation for this question:

[tex]800* (\frac{3}{5})^{t}[/tex]

t = time in years

So we can plug in 3 for t

[tex]800* (\frac{3}{5})^{3}[/tex]

[tex]800* (\frac{27}{125})[/tex]

[tex]172.8[/tex]

So the phone is now worth $172.80

The p-value shows that onea type of high school might not be better equip students to attain high academic honors at this college.

A p-value simply means a statistical measurement that is used to validate a hypothesis against the observed data.

Here, from the table, the p-value is 0.0393. Since the p-value is less than the level of significance which is 0.05, we are going to reject the null hypothesis.

It simply means that the observed values don't support the proportion given. Here, the p-value shows that one type of high school might not be better equip students to attain high academic honors at this college.

The linear cost function of the computer shop in this scenario will be C(x) = 649x + 1500.

From the information, the linear cost function is C(x) = 649x + 1500 and the linear revenue function will be R(x) = 899x.

The cost of selling 37 computers will be:

C(x) = 649x + 1500

C(x) = 649(37) + 1500

C = 25513

The revenue from selling 37 computers will be:

R(x) = 899x.

R = 899(37)

R = 33263

The breakeven point will be:

649x + 1500 = 899x

899x - 649x = 1500.

250x = 1500

Answer:

p > 8

Step-by-step explanation:

8p - 48 > 4p - 16

plus 48 on both sides

8p > 4p + 32

minus 4p on both sides

4p > 32

divide 4 on both sides, 32 ÷ 4 = 8, so,

p>8

Answer:

P > 8 ??? I don't know if this is right and if its not then sorry lol

Step-by-step explanation:

Multiply 8(p-6) and 4(p-4)

You will get 8p - 48 > 4p - 16

Then add 48 to -16

Then you will get 8p > 4p + 32

Then subtract 4p from 8p

Then you will get 4p > 32

Then divide 4 from 4p and 32

Then you will get p > 8

Answer:

We know that:

small diameter = 2 * 10^-2 in

large diameter = 6 * 10^-2 in

We want to know how many times larger is the thin diameter compared to the large one.

We will do this as follows:

large diameter = k * small diameter

where k is the number of times that we want to find

6 * 10^-2 = k * 2 * 10^-2

k = (6 * 10^-2) / (2 * 10^-2)

k = 3

This means that the large diameter is 3 times the small one.

The mean of the sampling proportion is 0.03 and the standard deviation of the sampling proportion is 0.008 if the probability that a student forgets to bring their ID with them when they take their SAT is 3%. and a random sample of 500 students was selected.

It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.

We have:

p = 0.03

n = 500 students

[tex]\rm {\hat p} - Normal[/tex]

So the mean:

[tex]\rm \mu _\hat p \ = \ p \ = \ 0.03[/tex]

For standard deviation:

[tex]\rm \sigma_p = \sqrt{\frac{pq}{m} }[/tex]

q = 1 - p = 1 - 0.03 = 0.97

[tex]\rm \sigma_p = \sqrt{\frac{0.03\times 0.97}{500} }[/tex]

[tex]\rm \sigma_p = 0.008[/tex]

Thus, the mean of the sampling proportion is 0.03 and the standard deviation of the sampling proportion is 0.008 if the probability that a student forgets to bring their ID with them when they take their SAT is 3%. and a random sample of 500 students was selected.

Answer:

Step-by-step explanation:

Answer:

Below in bold.

Step-by-step explanation:

a) we need the grestest common factor of  theses values

153 = 3 * 3 * 17

255 =  3 * 5*17

357 = 3 * 7 * 17

The GCF = 3 * 17 = 51.

a) the least possible number of children  is 3.

b) The maximum number is 51 ( as 51 is the GCF of the given values).

c) the least possible number of fruits is when  b)  occurs, that is:

153/51, 255/51 and 357/51

= 3 apples , 5 oranges and 7 pears.

d) the maximum number of fruits is :

153/3, 255/3 and 357/3

= 51 apples , 85 oranges and 119 pears.

Answer:

a) 3 children

b) 51 children

c) 3 apples, 5 oranges and 7 pears

d) 51 apples, 85 oranges and 119 pears

Step-by-step explanation:

lnc - Least possible number of children in group

mnc - maximum possible number of children in group

a - Apples

o - Oranges

p - Pears

a = 153

o = 255

p = 357

a)

To solve this, find the highest divisor for the apples, oranges and pears.

[tex]a = \frac{153}{51} [/tex]

[tex]a = 3[/tex]

[tex]o = \frac{255}{85} [/tex]

[tex]o = 3[/tex]

[tex]p = \frac{357}{119} [/tex]

[tex]p = 3[/tex]

In order for each child to get 51 apples, 85 oranges and 119 pears, there would need to be a minimum of 3 children in the group.

[tex]lnc \: = 3[/tex]

b)

To solve this, find the lowest divisor for the apples, oranges and pears.

[tex]a = \frac{153}{3} [/tex]

[tex]a = 51[/tex]

[tex]o = \frac{255}{5} [/tex]

[tex]o = 51[/tex]

[tex]p = \frac{357}{7} [/tex]

[tex]p = 51[/tex]

In order for each child to get 3 apples, 5 oranges and 7 pears, there would need to be a maximum of 51 children in the group.

[tex]mnc = 51[/tex]

c)

In a group of 51, each child will get:

- 3 apples

- 5 oranges

- 7 pears

d)

In a group of 3, each child will get

- 51 apples

- 85 oranges

- 119 pears

Answer:

[tex] \: [/tex]

Step-by-step explanation:

We'll solve this using the Pythagorean theorem, we know that,

[tex]\\ {\longrightarrow \pmb{\sf {\qquad (Hypotenuse {)}^{2}= (Base) {}^{2} + (Perpendicular {)}^{2} }}}[/tex]

So, As it is given in the question that, the length of one leg of a right triangle is 9 ft and the length of the hypotenuse is 3 feet longer than the other leg and we are to find the length of the hypotenuse and the other leg.

[tex] \: [/tex]

Let us assume the other leg as x ft and therefore the hypotenuse will be (x + 3) ft.

[tex] \: [/tex]

Now, substituting the values in the formula :

[tex] \\ {\longrightarrow \pmb{\sf {\qquad (x + 3 {)}^{2} = (9 {)}^{2} + (x) {}^{2} }}} \\ \\ [/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad (x {)}^{2} + 2.x.3 + {(3)}^{2} =81 + (x) {}^{2} }}} \\ \\ [/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad \cancel{ (x {)}^{2}} + 2.x.3 +9 =81 + \cancel{(x) {}^{2} }}}} \\ \\ [/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad 6x + 9 =81 }}} \\ \\ [/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad 6x =81 - 9 }}} \\ \\ [/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad 6x =72 }}} \\ \\ [/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad x = \frac{72}{6} }}} \\ \\ [/tex]

[tex]{\longrightarrow \pmb{\frak {\qquad x =12 }}} \\ \\ [/tex]

Answer:

129.3mm chain left without beads

Step-by-step explanation:

Equation:

400mm long chain - [(40 x 1.7mm) + (27 x 6.5mm) + (8 x 3.4mm)]

                   = chain left without beads

Calculation:  

         40 beads x 1.7mm = 68mm

         27 beads x 6.5mm = 175.5mm

         8 beads x 3.4mm = 27.2mm

         (68mm + 175.5 mm + 27.2mm) = 270.7mm chain with beads

         400mm chain - 270.7mm chain with beads

                   = 129.3mm chain left without beads
