I believe it’s the second one because it’s the only one that has the same variable.

The speed of sound in air is a linear function of the air temperature. When the air temperature is 10°C, the speed of sound is 337 m/s. When the air temperature is 30°C, the speed of sound is 349 m/s.

Can you please explain the process of writing this function as a linear equation?

Answer:

  process: substitute the given point values into the 2-point form of the equation for a line

Step-by-step explanation:

There are more than a half-dozen different forms of the equation for a line. They are useful for different purposes. One of them is the "two-point form".

Using x as the independent variable, and y as the dependent variable, the equation can be written as ...

  y -y1 = (y2 -y1)/(x2 -x1)/(x -x1)

where (x1, y1) and (x2, y2) are the two points.

__

Here, your two points are ...

  (t, s) = (10, 337) and (30, 349)

Using s in place of y, and t in place of x, these two points go into the formula like this:

  s -337 = (349 -337)/(30 -10)(t -10)

Simplifying the fraction, this is ...

  s -337 = (12/20)(t -10)

And writing it as a decimal, we get ...

  s -337 = 0.6(t -10)

_____

Additional comments

Adding y1 to both sides of the above form gives you ...

  y = (y2 -y1)/(x2 -x1)/(x -x1) +y1

This is the form I usually prefer to use, because it can lead directly to slope-intercept form. For this problem, the form shown above gets you to the answer you're looking for.

__

This "two-point form" is an expansion of the "point-slope form", which is ...

  y - k = m(x -h) . . . . . . . line with slope m through point (h, k)

where the equation for slope is ...

  m = (y2 -y1)/(x2 -x1)

and (x1, y1) is used instead of (h, k).

Answer:

The actual linear equation is s= 0.6t + 331 which can be rearranged to make s-337 = 0.6( t-10 ).

Step-by-step explanation:

Any linear equation has the formula y=Mx + c , where x is the independent variable , y is the dependent variable , m is the slope of the line and c is the y-intercept .

here y is replaced by “s” which stands for speed of sound and x is replaced by “t” which stands for temperature.

To find the slope , we divide gain  of “s” by gain of “t “

i.e. [tex]m= \frac{349-337}{30-10}= \frac{12}{20} = 3/5[/tex]

So the slope of the equation is 3/5 Or 0.6

lets plug s=337 and t= 10 into the equation s= 0.6t+ c

[tex]337= \frac{3}{5} (10) + c\\337 = 6 + c\\C= 331\\Hence the equation becomes s= 0.6t+ 331 \\Rearranging the equation , s-331 = 0.6t \\ subtracting 6 from both sides, s-331-6 = 0.6t-6\\S-337 = 0.6 ( t- 10 ) , which is given in your book.\\\\[/tex]

The last line is s-337 = 0.6t - 6 = 0.6(t-10 ) , which is given in your book.

Find the measure of the vertex angle.

Answers

Answer:

∠ Y = 34°

Step-by-step explanation:

Since XY = ZY then the triangle is isosceles and the base angles are congruent, thus

∠ X = ∠ Y , that is

6x - 23 = 4x + 9 ( subtract 4x from both sides )

2x - 23 = 9 ( add 23 to both sides )

2x = 32 ( divide both sides by 2 )

x = 16

Thus

∠ Z = 4x + 9 = 4(16) + 9 = 64 + 9 = 73° = ∠ X

Hence

vertex angle Y = 180° - (73 + 73)° = 180° - 146° = 34°

Answer: the answer is d :)

The equation to represent the total cost of printing the calendars is y=500+2.50x.

What is the slope intercept form?

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

1) Given that, the cost of printing is $500, plus $2.50 per calendar.

Let the number of calendars be x and let the total cost be y.

So, the equation is y=500+2.50x

2) Each calendar will sell for $5.00 each.

The total income, y, for selling x calendars.

So, the total income is y=5.00x

Cameron estimates that the math class will sell 200 calendars.

So, the total cost = 5.00×200

= $1000

Now, y=500+2.50x

Substitute x=200 in y=500+2.50x, we get

y=500+2.50×200

y=1000

Hence, option D is the correct answer.

Therefore, the equation to represent the total cost of printing the calendars is y=500+2.50x.

Manuel wants to earn at least $44 trimming trees. He charges $6 per hour and pays $4 in equipment fees. What are the possible numbers of hours Manuel could trim trees? Use (t) for the number of hours. Write your answer as an inequality solved for (t).

Answers

Given:

Manuel wants to earn at least $44 trimming trees.

He charges $6 per hour and pays $4 in equipment fees.

To find:

The possible numbers of hours Manuel could trim trees.

Solution:

Let t be the numbers of hours Manuel could trim trees.

Earnings of Manuel in one hour = $6

Earnings of Manuel in t hour = $6t

He pays $4 in equipment fees. So, we will subtract this from the income.

[tex]\text{Total earnings}=6t-4[/tex]

Manuel wants to earn at least $44 trimming trees. It means, total earnings must be greater than or equal to 44.

[tex]6t-4\geq 44[/tex]

[tex]6t\geq 44+4[/tex]

[tex]6t\geq 48[/tex]

Divide both sides by 6.

[tex]t\geq \dfrac{48}{6}[/tex]

[tex]t\geq 8[/tex]

Therefore, the required number of hours must be greater than or equal to 8 hours.

You pick a card at random. Without putting the first card back, you pick a second card at random. Card numbers are 2, 3, 4, and 5 What is the probability of picking a 2 and then picking a number greater than 3? (Write your answer as a fraction or whole number.)

Answers

Answer:

1/6

Step-by-step explanation:

When trying to calculate the probability of a sequence of events you need to multiply the probability of the first event happening by the probability of the second event happening. There are a total of 4 numbers (2,3,4,5) and only one is a 2. Therefore the probability of the first pick being a 2 is 1/4. Now there are only 3 cards left (3,4,5) and only 2 numbers are greater than 3 so the probability of picking one of these cards is 2/3. Now that we have both of these probabilities we simply multiply them together.

1/4 * 2/3 = 2/12 or 1/6

Therefore, the probability of picking a 2 and then picking a number greater than 3 is 1/6
