the jasmine family kept a log of the distance they traveled during a trip, as represented by the graph below
during which interval was their average speed the greatest

Nathan's salary is $48 and Will's salary which three times of Nathan's salary is $144.

What is salary?

An employment contract may include a salary clause as a type of recurring payment from an employer to an employee. In contrast, piece wages are paid separately for each job, hour, or other unit rather than on a regular schedule. Salary can also be seen from the perspective of operating a corporation as the expense of obtaining and keeping employees to carry out operations; this is known as a personnel expense or salary expense. Payroll accounts are used in accounting to record salaries.

It is given in the question that Will's salary is three times Nathan's salary.

So, lets assume that Nathan's salary is X it implies that Will's salary will be 3 times X = 3X

Together they earn $ 192.

So,

X + 3X = 192

4X = 192

X = 192/4

X = 48

Therefore, Nathan's Salary is $48

Since, Will's salary is 3 times of Nathan's salary,

So,

Will's salary = 3 (48) = 144

Therefore, Will's Salary is $144

Let g = cost of granola bars

b = cost of a bottle of water

10g+12b = 23

5g + 4b = 10

Multiply the second equation by -2

-10g -8b = -20

Add this to the first equation

10g+12b = 23

-10g -8b = -20

---------------------

4b = 3

Divide by 4

4b/4 = 3/4

b = 3/4 or .75

Now find g

5g + 4(3/4) = 10

5g + 3 = 10

The slope of the line = change in y / change in x = 4/3.

The slope of a line is the rise over the run, which is the change in y/change in x = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

To calculate the slope of the line that is given, chose any two points on the line as plotted in the given graph, say:

We need to use simple division to solve the problem. The number of cards each friend received is 11.

It is said that Landon has 56 cards, he kept 12 cards for himself, so we can subtract 12 cards from the whole lot to get the total number of cards he distributes among his friends.

56-12=44

There are 44 cards that he will distribute among his friends equally, we can get that by simply dividing the total number of cards by the number of friends which is 4.

number of cards for each friend=44/4=11

There is a mistake in the first step. The correct way to add the linear expression is (−3.78b + 12) − (4.82b − 16) = -8.6b + 18

An expression is used to show the relationship between the variables.

The linear expression to add is as follows: (−3.78b + 12) − (4.82b − 16)

Firstly we open the bracket on the right side by multiplying the negative sign by the numbers in the brackets.

(−3.78b + 12) − (4.82b − 16)

−3.78b + 12 - 4.82b + 16

Combine like terms

−3.78b + 12 - 4.82b + 16

-3.78b - 4.82b + 12 + 16

The slope of the line is 3/7.

The slope of line will be calculated using the formula :

Slope = [tex] \frac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

The first point is (-2, 7) and second point is (-9, 4). So, [tex] y_{2}[/tex] = 4, [tex] y_{1}[/tex] = 7, [tex] x_{2}[/tex] = -9 and [tex] x_{1}[/tex] = -2. Keep the values in formula to find the values of slope of the line.

Slope = (4 - 7)/(-9 - -2)

The name for the angle <2&<7 is an alternate interior angle by a transversal x.

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.

The angle pairs are given.

From the diagram:

<2&<7 = Alternate interior angle by a transversal x

<5 & <8 = Consecutive exterior angle by a transversal x

<9 & <16 = Consecutive exterior angle by a transversal x

<1 & <3 = Corresponding angles by transversal x

<4 & <3 = Adjacent angle by transversal g

<14 & <15 = Consecutive interior angle by a transversal y

Answer:

  27. 48°, 132°

  28. The expressions resolve to both angles being 0°, a contradiction to the lines being distinct.

Step-by-step explanation:

Given a figure showing parallel lines crossed by a transversal with marked angles, you want to know (27) the measures of consecutive interior angles that have a ratio of 4:11, and (28) the contradiction in corresponding angles being marked (60-2x)° and (2x-60)°.

The two marked angles are consecutive interior angles, so are supplementary. Using x for the smaller angle value, we can write the equation ...

  x/(180-x) = 4/11 . . . . . the given ratio of the two angles

Multiplying by 11(180-x) gives ...

  11x = 4(180-x)

  15x = 4(180) . . . . add 4x and simplify

  x = 48 . . . . . . . . divide by 15

Then the obtuse angle is ...

  180 -48 = 132

The measures of the angles are ∠1 = 48°, ∠2 = 132°.

The two marked corresponding angles are congruent, so ...

  (60 -2x)° = (2x -60)°

  4x = 120 . . . . . . . . . . . divide by °, add 2x+60

  x = 30 . . . . . . . . . . divide by 4

  60 -2x = 60 -2(30) = 0

  2x -60 = 2(30) -60 = 0

The marked values require the angles to be 0°, which means the transversal is coincident with each of the "parallel" lines.

The given angle values require the lines not to be distinct, as the diagram shows they are.

Step-by-step explanation:

this is really hard to read but you have to see which y values increase by a constant amount. Only the last case is linear in which each value increases by 3

the dimensions of the box that minimize the amount of material used is 4.641cm by 4.641cm by 2.32cm

Let the side of the square base be x

h be the height of the box

Volume V = x²h

50 = x²h

h = 50/x² ..... 1

Surface area =  x² + 2xh + 2xh

Surface area S =  x² + 4xh  ...... 2

Substitute 1 into 2;

From 2; S =  x² + 4xh

S = x² + 4x(50/x²)

S = x² + 200/x

To minimize the amount of material used; dS/dx = 0

dS/dx = 2x - 200/x²

0 = 2x - 200/x²

0 = 2x³ - 200

2x³ = 200

x³ = 100

x = ∛100

x = 4.6416cm

Since V = x²h

50 = 4.642²h

h = 50/21.548

h = 2.32cm

Hence the dimensions of the box that minimize the amount of material used is 4.641cm by 4.641cm by 2.32cm

Yes, I do agree with Jamie.

1 is NEITHER a prime number NOR a composite number.

Reason for agreeing:-

We know that a PRIME NUMBER is any given number that has only one as a factor. I.e it is only divisible by 1 AND ITSELF.

And, a COMPOSITE NUMBER is any number that is divisible by a number other than one and itself.

Here in the case of 1, we see that it is divisible by 1 and itself, and since it cannot have any other factor we can't put in either of the two categories

The four functions with a local minima are:

y = x², y = |x|, y = sin x, y = cos x

A function f(x) has a local minima if its second derivative, f''(x) > 0 at the point where f'(x) = 0.

We use this to find which among the functions y = x, y = x², y = x³, y = |x|, y = 1/x, y = eˣ, y = √x, y = ln x, y = sin x, y = cos x, y = int(x), y = 1/(1+e⁻ˣ) has a local minima.

y' = 1. There is no point x such that y' = 0. So it has no local minima.

y' = 2x

y' = 0

⇒ 2x = 0

⇒ x = 0

y'' = 2 > 0

So y = x² has a local minima at x = 0

y' = 3x²

y' = 0

⇒ 3x² = 0

⇒ x = 0

y'' = 6x = 0 at x = 0

So y = x³ has no local minima.

i.e., y = x, when x ≥ 0 and y = -x , when x < 0

So y ' = 1, when x ≥ 0 and y' = -1, when x < 0

But at x = 0, y = 0 and y' = 0.

Now y'' = 0 everywhere. But the graph of y = |x| clearly shows that y = |x| has a local minimum at x = 0.

y' = -1/x²

Here, y' is nowhere zero and hence doesn't has a local minima.

y' = eˣ

 eˣ is nowhere zero and hence it does not has a local minima.

y' = 1/2√x

Here also  y' is nowhere zero and hence it does not has a local minima.

y' = 1/x

Here also y' is  nowhere zero and hence it does not has a local minima.

y' = cos x

y' = 0

⇒ cos x = 0

⇒ x = (2n+1)π/2, n = 0,1,2,....

y'' = -sin x

-sin ((2n+1)π/2)  = -1, when n = 0,2,4,... and -sin ((2n+1)π/2)  = 1, when n = 1,3,5,....

So y = sin x has local minima at x = (2n+1)π/2, where n = 1,3,5,....

y' = -sin x

y' = 0

⇒ -sin x = 0

⇒ x = nπ

y'' = -cos x

-cos(nπ) = (-1)ⁿ⁺¹

So, -cos(nπ) = 1, when n = 1,3,5,.... and -cos(nπ) = -1, when n = 0,2,4,...

Hence y = cos x has local minima at x = nπ with n = 1,3,5,....

y' = x

y' = 0

⇒ x = 0

y'' = 1 >0

So y = int (x) has local minima at x = 0

y' = e⁻ˣ/(1+e⁻ˣ)²

y' = 0

⇒ e⁻ˣ/(1+e⁻ˣ)² = 0

⇒ e⁻ˣ = 0

⇒ 1/eˣ = 0 which is not possible anywhere.

Hence y = 1/1+e⁻ˣ has no local minima.

Finally the four functions with local minima are:

y = x², y = |x|, y = sin x, y = cos x
