Yes, these numbers meet the triangular inequalities, then these can be the measures of the sides of a triangle.

Remember that if A, B, and C are the sides of a triangle, then the triangle inequality says that:

A + B > C

A + C > B

C + B > A

As long as 3 values are solutions of the inequalities, then these can be the sides of a triangle.

if we use:

A = 7

B = 10

C = 10

Then we get:

7 + 10 > 10 ---> 17 > 10

7 + 10 > 10 ---> 17 > 10

10 + 10 > 7 ---> 20 > 7

A, C, B, and D make up the list of ABCD's angles, from largest to smallest, with 90°, 54°, 24°, and 12°, respectively.

The sides of a triangle, or angle, are two rays that make up the figure. The Law of Cosines can be used to find Angle A. We can solve for the angle A by using the formula

                               c² = a² + b² - 2abcos(C).

Since we know the lengths of all sides, we can substitute in the values.                                    

                        c² = 122 + 102 - 2(12)(10)cos(A)

                          Cos(A) = (144 + 100 - 120)/240

                       = 24/240

                       = 0.1

In the end, we use the inverse cosine to determine the angle A, which is roughly 74 degrees.

The same formula can be used to determine Angle D.

                                c² = 62 + 102 - 2(6)(10)cos(D)

                              Cos(D) = (36 + 100 - 60)/120

                                       = 76/120

                                               = 0.63 .

When we take the inverse cosine, we get the angle D, which is about 27.3 degrees.

The same formula can be used to determine Angle C.

                                 c² = 122 + 62 - 2(12)(6)cos(C)

                                      Cos(C) = (144 + 36 - 72)/144

                                                 = 108/144

                                       = 0.75

When we take the inverse cosine, we get the angle C, which is about 36.9 degrees.

The same formula can be used to determine Angle B.

                              c² = 122 + 102 - 2(12)(10)cos(B) .

                               Cos(B) = (144 + 100 - 120)/240

                                                 = 24/240

                                                = 0.1

We obtain the angle B, which is roughly 74 degrees, by applying the inverse cosine.

Therefore, ABCD's angles, from largest to smallest, are as follows: angle C (36.9°), angle B (74°), and angle D (27.3°)

Step-by-step explanation:

Patricia has  6 cans of almonds that each contain eight 1/3 cup servings, meaning that Patricia has a total of

6 cans x 8 servings x 1/3 cup = 16 cups of almonds

If she needs 2.25 cups of almonds, that would be equal to

A two variable linear equation means an equation having two variables. It is usually represented as ax+by =c. We can solve a two variable linear equation in many ways.

If the linear equation is only given, to solve it we have to calculate the x-intercept and y-intercept. It is one way of solving a two variable linear equation. Lets look into an example.

 2x+5y = 19

The x intercept is when y=0,

then, 2x+ (5×0) = 20

          2x = 20, x=10

y intercept is when x=0, then

2×0 + 5y = 20

   5y = 20,  y= 20/5 =4

So, by solving the equation, we get x=10 at x intercept and y=4 at y intercept.

If one the values are given , we can substitute it in the equation to calculate the other variable.

In the equation, 2x+3y= 12, if y=2, we can calculate by substituting.

    2x + (3×2) = 12

     2x = 12-6

     2x = 6

      x =3

So when y=2 then x=3.

Constraints are the restrictions on the domain of a linear equation, like a number of days or students should be a positive integer.

So, we can solve a two variable linear equation through different ways.

Out of the given vectors is in the span of the other vectors,  b. One of the vectors is in the span of the other vector. Since u and v have the same last component, they are linearly dependent, so u is in the span of v and w.

If a set of vectors is linearly dependent, then one of the vectors can be expressed as a linear combination of the other vectors. This means that one vector is in the span of the other vectors. In this case, u can be expressed as a linear combination of v and w, so u is in the span of the other vectors.  

To check for linear dependence, we can first check for a zero row in the matrix formed by the vectors. If there is a zero row, then the vectors are linearly dependent. In this case, the last row of the matrix formed by the vectors is [3,3,0], which is a zero row, so the vectors are linearly dependent.  We can also check for linear dependence by computing the determinant of the matrix formed by the vectors.

The average velocity (in m/s) over the given time intervals is [1,2]

Part A.

Keep in mind that the formula for average velocity is

(Y2 - Y1)/V avg = displacement/time interval (t2 - t1)

Given that the rock's position at time t is determined by:

y = 16t - 1.86*t^2

Part 1

for the time period [1, 2]

Y1 = 16*1 - 1.86*12 = 14.14 m when t1 = 1 sec.

Y2 = 16*2 - 1.86*22 = 24.56 m when t2 = 2 sec.

So

average Velocity = (24.56 - 14.14)/(2 - 1) (2 - 1) = 10.42 m/s V avg

Part 2.

for the time period [1, 2]

Y1 = 16*1 - 1.86*12 = 14.14 m when t1 = 1 sec.

Y2 = 16*1.5 - 1.86*1.52 = 19.815 m when t2 = 1.5 sec.

So,

average Velocity  = (19.815 - 14.14)/(1.5 - 1) (1.5 - 1) = 11.35 m/s V avg

Part 3.

During the period [1, 1] .1]

Y1 = 16*1 - 1.86*12 = 14.14 m when t1 = 1 sec.

Y2 = 16*1.1 - 1.86*1.12 = 15.3494 m when t2 = 1.1 sec.

So,

average Velocity  = (15.3494 - 14.14)/(1.1 - 1) (1.1 - 1)

average Velocity = 12.094 m/s and equals 12.09 m/s (In two decimal places)

Part 4.

During the period [1, 1] .01]

Y1 = 16*1 - 1.86*12 = 14.14 m when t1 = 1 sec.

Y2 = 16*1.01 - 1.86*1.012 = 14.262614 m when t2 = 1.01 sec.

So,

average Velocity = (14.262614 - 14.14)/(1.01 - 1) (1.01 - 1)

12.26 m/s and V avg = 12.2614 m/s (In two decimal places)

Part 5.

During the period [1, 1] .001]

Y1 = 16*1 - 1.86*12 = 14.14 m when t1 = 1 sec.

Y2 = 16*1.001 - 1.86*1.0012 = 14.15227814 m when t2 = 1.001 sec.

So,

average Velocity = (14.15227814 - 14.14)/(1.001 - 1) (1.001 - 1)

12.28 m/s V avg = 12.27814 m/s (In two decimal places)

Part B.

Rock's immediate velocity will be determined by:

d[16t - 1.86t2]/dt = V= dy/dt

Velocity = 16*1 - 2*1.86*t

time = 1 second,

Velocity = 16 - 2*1.86*1

average velocity at time t is equal to V = 12.28 m/s.

The linear equation y = - 4 · x + 1 includes point (x, y) = (2, - 7).

In this problem we need to plot a linear equation on Cartesian plane, linear equations are first polynomials of the form:

y = m · x + b

Where:

If we know that b = 1 and (x, y) = (2, - 7), then the equation of the line is:

- 7 = 2 · k + 1

- 8 = 2 · k

k = - 4

y = - 4 · x + 1

Now we proceed to graph the line. First, find two points of the line:

x = 0

y = - 4 · 0 + 1

y = 1

x = 1

y = - 4 · 1 + 1

y = - 3

The artist charges $25 for a small painting and $65 for a large painting.

How to substitute two equations?

To substitute one equation into another, you can replace one of the variables in the second equation with the expression from the first equation.

Let K be the price of small painting and L be the price of large painting.

From the information given, we know that:

Last month:

6K + 8L = $670 (1)

This month:

12K + 10L = $950 (2)

We have two equations and two unknowns, so we can use a system of equations to find the values of K and L.

Solving the system of equations:

From (1) equation, we have:

6K + 8L = $670

From (2) equation, we have:

12K + 10L = $950

Now we can solve for K (small painting) by multiplying equation (1) by 2 and equation (2) by -1 and adding the two equations together:

12K + 16L = $1340

-12K - 10L = -$950

0K + 6L = $390

Therefore, L = $390 / 6 = $65

Now we can substitute this value of L back into the first equation (1) and solve for K:

6K + 8($65) = $670

6K = $670 - 8($65) = $670 - $520 = $150

K = $150 / 6 = $25

So, the artist charges $25 for a small painting and $65 for a large painting.
