domain is all real numbers
range is all real numbers greater than 3

Answer 2

Answer:

Step-by-step explanation: Domain are the set of x -values. Here x values from negative to positive.

Range is the set of y values. The graph clearly shows that the values never dip below 3.

Hence the answer is ;

Domain : All x values

Range: never dips below 3.

We can use the right outside diagonal of the empty Lacsap's triangle as the coefficients of a polynomial: $$t^3 + 6t^2 + 12t + 8.$$ If we replace every $t$ with $t-1,$ we get $$(t-1)^3 + 6(t-1)^2 + 12(t-1) + 8.$$Expand and simplify this polynomial. Enter the polynomial as your answer.

Answers

The given equation with t -1 is:
(t – 1)^3 + 6 (t – 1)^2 + 12 (t – 1) + 8

Expand each term before combining for easier visualization:
(t – 1)^3 = t^3 – 3 t^2 + 3t – 1
6 (t – 1)^2 = 6 t^2 – 12 t + 6
12 (t – 1) = 12 t - 12

Then substitute and combine:
-> t^3 – 3 t^2 + 3t – 1 + 6 t^2 – 12 t + 6 + 12 t – 12 + 8

t^3 + 3 t^2 + 3 t + 1 (ANSWER)

Final answer:

To expand the given polynomial $(t-1)^3 + 6(t-1)^2 + 12(t-1) + 8$, we can apply the binomial theorem to each term and then combine like terms.

Explanation:

To expand the polynomial $$(t-1)^3 + 6(t-1)^2 + 12(t-1) + 8,$$ we can start by applying the binomial theorem to each term:

$$(t-1)^3 = t^3 - 3t^2 + 3t - 1$$

$$6(t-1)^2 = 6(t^2 - 2t + 1) = 6t^2 - 12t + 6$$

$$12(t-1) = 12t - 12$$

$$8$$

Now, we can combine like terms:

$$t^3 - 3t^2 + 3t - 1 + 6t^2 - 12t + 6 + 12t - 12 + 8$$

Cancelling out terms that add up to zero, we are left with:

$$t^3 + 6t^2 + 12t + 8$$

How do I find slope?

Suppose m<3 = 105. find m<6

Answers

To find the measure of angle 6, we can use the fact that angles 3 and 6 are vertical angles (opposite angles formed by the intersection of two lines). Therefore, their measures are equal.

Given that[tex]$ m\angle 3 = 105^\circ $, we have $ m\angle 6 = m\angle 3 = 105^\circ $.So, the measure of angle 6 is $ \boxed{105^\circ} $.[/tex]

The measure of angle 6 is 105 degrees. This is because angles 3 and 6 are vertical angles, meaning they are formed by intersecting lines and are opposite each other. According to the Vertical Angles Theorem, vertical angles are congruent, meaning they have the same measure. Therefore, if angle 3 measures 105 degrees, angle 6, being its vertical angle, also measures 105 degrees. This principle holds true regardless of the specific configuration of lines or shapes, as long as the angles are formed by intersecting lines. Hence, in this case, the measure of angle 6 directly corresponds to the measure of angle 3 due to their relationship as vertical angles, resulting in both having a measure of 105 degrees.

For what values of r does the function y = erx satisfy the differential equation y'' − 6y' + 2y = 0? (enter your answers as a comma-separated list.)

Answers

The values of [tex]r[/tex] is [tex]\boxed{r = 3 - \sqrt7 }[/tex] and [tex]\boxed{r = 3 + \sqrt 7 }.[/tex]

Further explanation:

Given:

The function is [tex]y = {e^{rx}}.[/tex]

The differential equation is [tex]y'' - 6y' + 2y = 0\,\,\,\,\,or\,\,\,\,\dfrac{{{d^2}y}}{{d{x^2}}} - 6\dfrac{{dy}}{{dx}} + 2y = 0[/tex]

Explanation:

The given function can be expressed as follows,

[tex]y = {e^{rx}}[/tex]

Differentiate the above equation with respect to [tex]x[/tex].

[tex]\begin{aligned}\frac{{dy}}{{dx}} &= \frac{d}{{dx}}\left( {{e^{rx}}} \right)\\&= {e^{rx}} \times \frac{d}{{dx}}\left( {rx} \right)\\&= {e^{rx}} \times r\\&= r{e^{rx}}\\\end{aligned}[/tex]

Again differentiate with respect to [tex]x[/tex].

[tex]\begin{aligned}\frac{{{d^2}y}}{{d{x^2}}} &= \frac{d}{{dx}}\left( {r{e^{rx}}} \right)\\&= r\frac{d}{{dx}}\left( {{e^{rx}}} \right)\\&=r\times {e^{rx}} \times\frac{d}{{dx}}\left( {rx} \right)\\&= {r^2}{e^{rx}}\\\end{aligned}[/tex]

Now solve the differential equation.

[tex]\begin{aligned}y'' - 6y' + 2y &= 0\\{r^2}{e^{rx}} - 6r{e^{rx}} + 2{e^{rx}} &= 0\\{e^{rx}}\left( {{r^2} - 6r + 2} \right) &= 0\\{r^2} - 6r + 2 &= 0\\\end{aligned}[/tex]

Solve the quadratic equation [tex]{r^2} - 6r + 2 = 0.[/tex]

[tex]\begin{aligned}D&= {b^2} - 4ac\\&={\left( { - 6} \right)^2} - 4\left( 1 \right)\left( 2 \right)\\&= 36 - 8\\&= 28\\\end{aligned}[/tex]

The value of [tex]r[/tex] can be obtained as follows,

[tex]\begin{aligned}r&= \frac{{ - b \pm \sqrt D }}{{2a}}\\r&=\frac{{ - \left( { - 6} \right) \pm \sqrt {28} }}{{2 \times 1}} \\ r &= \frac{{6 \pm 2\sqrt7 }}{2}\\r&= 3 \pm \sqrt7\\r&= 3 - \sqrt 7 \,\,\,\,\,\,\,or\,\,\,\,\,\,\,r = 3 + \sqrt7 \\\end{aligned}[/tex]

The values of [tex]r[/tex] is [tex]\boxed{r = 3 - \sqrt7 }[/tex] and [tex]\boxed{r = 3 + \sqrt 7 }.[/tex]

A 1-ounce serving of cream cheese contains 7.8

grams of saturated fat. How much saturated fat is in 12

ounces of cream cheese?

Answers

Sent a picture of the solution to the problem (s). Proportions are a quick set up to find a part of two things being compared. You will use this method a lot in math and science.

Final answer:

To find the total grams of saturated fat in 12 ounces of cream cheese, multiply the grams per ounce (7.8) by the total ounces (12), which equals 93.6 grams.

Explanation:

To answer this question, we need to multiply the amount of saturated fat in one ounce of cream cheese by the total number of ounces you have. Since one ounce of cream cheese contains 7.8 grams of saturated fat, you would multiply 7.8 by 12 (the total number of ounces) to get the total amount of saturated fat.

7.8 grams of saturated fat per ounce × 12 ounces = 93.6 grams

So, 12 ounces of cream cheese contains 93.6 grams of saturated fat.

The price of a shampoo, cut, and style at the hairstyling salon where you work is $18.00. You generally get a 20% tip from each customer, and the salon owner pays you 1/4 of each job's cost. On a typical day, you give shampoos, cuts, and styles to 8 customers. About how much can you expect to earn on such a day?

Answers

$4.5 per service x 8 = $36.00

$18.00 x 8 = $144 x 20% = $29.00

$65.00

Answer:

You can expect $65.00 to earn on such a day.

Step-by-step explanation:

The price of shampoo, cut and style = $18.00

you generally get a tip from each customer = 20% of $18.00

0.20 × 18.00 = $3.60

Salon owner pays 1/4 of each job's cost = [tex]\frac{1}{4}[/tex] of $18.00

[tex]\frac{1}{4}[/tex] × 18.00 = $4.50

Total earning from each customer = 3.60 + 4.50 = $8.10

On a typical day, you serve 8 customers,

so the earning of each day = 8.10 × 8 = $64.80 ≈ $65.00

You can expect $65.00 to earn on such a day.

The equation y = 6.3x + 67.4 is the equation of a linear model in a scatter plot comparing the ages of boys between 2 and 10 years old open (x) and their average heights in centimeters open (y).

What is the average height of a 5-year-old boy?

98.9 cm

78.7 cm

67.4 cm

62.4 cm

Answers

Since the age of the boy is represented using x,
when the boy is 5 years old, x = 5.
y = 6.3x + 67.4
= 6.3(5) + 67.4
= 98.9

Since the average height of an age group is represented using y,
when y = 98.9, the average height of a 5-year-old boy is 98.9 cm.

The answer is 98.9 cm.

The average height of a 5 year old baby can be obtained by substituting the x and y values into the regression equation ; Hence, the average height of the baby is 98.9 cm

Given the linear regression equation :

y = 6.3x + 67.4

x = age of baby = 5 ; y = height of baby

The average height of a 5 year old baby is thus :

y = 6.3(5) + 67.4

y = 31.5 + 67.4

y = 98.9

Hence, the average height a 5 year old baby will be 98.9cm

Divide 300 in a ratio of 3:7

Answers

now, if we divide 300 by (3+7), we get 10 equal pieces, then we give 3 of those pieces to one side, and 7 of those pieces to the other side.

[tex]\bf \textit{300 at 3:7 ratio}\qquad \cfrac{3\left( \frac{300}{3+7} \right)}{7\left( \frac{300}{3+7} \right)}\implies \cfrac{3\left( \frac{300}{10} \right)}{7\left( \frac{300}{10} \right)}\implies \cfrac{3(30)}{7(30)}\implies \cfrac{90}{210}[/tex]

and of course, 90 + 210 = 300.

Final answer:

To divide 300 by a ratio of 3:7, calculate the value of each part by dividing 300 by the sum of the ratio parts (10) and then multiply by each part of the ratio to get 90 and 210, respectively.

Explanation:

To divide 300 in a ratio of 3:7, first add the parts of the ratio together to determine how many parts you will split 300 into.

In this case, 3 + 7 equals 10 parts.

Then, you divide 300 by 10 to find out how much one part is worth.

This gives 300 ÷ 10 = 30. Now, to find the amounts corresponding to the ratio, multiply the single part value by the numbers in the ratio. For the first part (ratio 3), multiply 30 by 3 to get 90.

For the second part (ratio 7), multiply 30 by 7 to get 210.

So, 300 divided in a ratio of 3:7 gives us 90 and 210, respectively.
