=3^a is 3^-2 and a is -2

The vectors u=[−10 5], v=[13 −5], and w=[−11 25] are linearly dependent. we can find the scalars c1, c2, and c3 that satisfy the equation u+v+w=0.

To find the scalars that satisfy the equation u+v+w=0, we need to determine a nontrivial linear combination of the vectors that equals zero.

To check for linear independence, we construct a matrix A using the given vectors as its columns. If the rank of A is less than the number of columns (in this case, 3), then the vectors are linearly dependent.

A = [u v w] = [[-10 5] [13 -5] [-11 25]]

We can row reduce the matrix A to determine its rank. After row reduction, we find that the rank of A is 2, which is less than 3. Therefore, the vectors u, v, and w are linearly dependent.

To find the scalars that satisfy the equation u+v+w=0, we can write it as a linear combination:

c1u + c2v + c3w = 0

Substituting the values of u, v, and w, we have:

c1[-10 5] + c2[13 -5] + c3[-11 25] = [0 0]

Simplifying, we get the system of equations:

-10c1 + 13c2 - 11c3 = 0

5c1 - 5c2 + 25c3 = 0

Answer:

30.2083 square feet

Step-by-step explanation:

For a second order differential equation t²y'' - 4ty' + 6y = 0, general solution is of the form y(t) = c₁t² + c₂t³, so another solution other than y₁(t) = t² is y₂(t) = t³.

Given solution to t²y'' - 4ty' + 6y = 0 is

y₁(t) = t²

Using the method of reduction of order, let us assume, y₂(t) = v(t)y₁(t) is a solution to t²y'' - 4ty' + 6y = 0 for suitable choice of v(t). So,

y₂ = vt²

y₂' = 2vt + t²v'

y₂'' = 2v + 2tv' + 2tv' + t²v''

y₂'' = 2v + 4tv' + t²v''

Substituting this

t²×( 2v + 4tv' + t²v'') - 4t×(2vt + t²v') + 6×(vt²) = 0

t⁴v'' = 0

v'' = 0

v' = c, c is a constant

v = ct

Therefore, y₂(t) = ct×t²

y₂ (t) = ct³

Therefore general solution will be y(t) = c₁t² + c₂t³

Answer:

Option (1)

Step-by-step explanation:

Lines X and Y are intersecting at a point.

Two pairs of vertical angles have been formed at the point of intersection.

1). ∠1 and ∠3

2). ∠2 and ∠4

It's given that m(∠1) = m∠3 = 55° [Since pair of vertical angles are equal in measure]

If line Y is rotated 5° clockwise about the point of intersection of both the lines,

∠1 and ∠3 both will increase by 5°.

Therefore, measure of angles 1 and angle 3 will become (55° + 5° = 60°).

Option (1) will be the answer.

The new measure of angle 3 is 60 degrees

When a point or line is rotated, it must be rotated about a point of rotation

The angle measure is given as:

\(\angle 1 = 55^o\)

By vertical angle theorem, we have:

\(\angle 3 = \angle 1\)

So, the angle measure becomes

\(\angle 3 = 55^o\)

The angle of rotation is given as: 5 degrees.

So, the new measure of angle 3 is:

\(\angle 3 = 55^o + 5^o\)

\(\angle 3 = 60^o\)

Hence, the new measure of angle 3 is 60 degrees

The new path is 400 feet shorter than the original path.

Here we have to find that the new path is how much shorter than the old path.

Given data:

xy = 1200 feet

yz = 500 feet

They are perpendicular.

The original path = 1200 + 500

= 1700 feet

The new path is in the form of a right-angle triangle, and we have to find the hypotenuse.

Formual to find the hypotenus:

Hypotenus² = Perpendicular² + Base²

Perpendicular = 500

base = 1200

hypotenus² = 500² + 1200²

= 250000 + 1440000

= 1690000

hypotenuse = 1300

shortest path = 1300 feet

Difference = original path- shortest path

= 1700 - 1300

= 400feet

Therefore 400 shorter feet is the new path.

The best type of study to make this determination would be an Experimental study.  (C)

In an experimental study, the researcher manipulates one or more variables and measures the effect on another variable. In this case, the variable being manipulated is the new medicine, and the variable being measured is the healing time of the bruise.

By comparing the healing time of bruises treated with the new medicine to those not treated, the pharmaceutical company can determine if their new medicine is effective.

An experimental study (C) is the best choice for this type of research because it allows the researcher to control for other variables that may affect the outcome, such as the severity of the bruise or the age of the patient. This control helps to ensure that any differences in healing time are due to the new medicine and not other factors.

A survey would not be appropriate because it would not allow for the manipulation of variables or the control of other factors.

A simulation would also not be appropriate because it would not involve actual patients or real bruises. An observational study would not be appropriate because it would not allow for the manipulation of variables or the control of other factors.

We determined the points of intersection, identified which function is on top in different intervals, and integrated the absolute difference between the functions over the interval [-3, 5].

To find the area of the region enclosed by the graphs of f(x) = x^2 - x - 5 and f(x) = x + 10, we need to determine the points of intersection between the two functions and integrate the absolute difference between them.

First, let's find the points of intersection by setting the two equations equal to each other:

x^2 - x - 5 = x + 10

Rearranging the equation, we get:

x^2 - 2x - 15 = 0

Factoring the quadratic equation, we have:

(x - 5)(x + 3) = 0

So the two points of intersection are x = 5 and x = -3.

Next, we need to determine which function is on top in the region

between these two intersection points.

For x < -3, the function f(x) = x + 10 is on top.

For -3 < x < 5, the function f(x) = x^2 - x - 5 is on top.

For x > 5, the function f(x) = x + 10 is on top.

To find the area, we integrate the absolute difference between the two functions over the interval [-3, 5].

∫[from -3 to 5] |(x^2 - x - 5) - (x + 10)| dx

Simplifying, we have:

∫[from -3 to 5] |x^2 - 2x - 15| dx

Now, we split the integral into two parts based on the intervals where the absolute value changes its sign.

∫[from -3 to 5] (x^2 - 2x - 15) dx + ∫[from -3 to 5] -(x^2 - 2x - 15) dx

Integrating each part separately, we obtain:

[(1/3)x^3 - x^2 - 15x] from -3 to 5 - [(1/3)x^3 - x^2 - 15x] from -3 to 5

Simplifying further, we get:

[(1/3)(5)^3 - (5)^2 - 15(5)] - [(1/3)(-3)^3 - (-3)^2 - 15(-3)]

Calculating the values, we find:

[125/3 - 25 - 75] - [-27/3 - 9 + 45/3]

The final result is the absolute value of the difference of these two values.

There are many more people awaiting such a transplant than there are available organs, leading to a large backlog of patients who are not able to receive an organ transplant.

In 2008, the United States Department of Health and Human Services reported that there were approximately 113,000 patients in the United States awaiting organ transplants. Of those, only 28,535 received an organ transplant that year. This is a ratio of approximately 1 in 4. This can be expressed mathematically as 28,535/113,000 = 0.25, or one fourth. This means that for every 4 people awaiting an organ transplant in the United States in 2008, only 1 actually received one.

Answer:

\(m\widehat{VU}=120^{\circ}\)

Step-by-step explanation:

The angle \(\angle TUV\) forms arc \(\widehat{TV}\). The measure of this arc is twice the measure of angle \(\angle TUV\), since \(U\) is a point on the circle. Since \(\overline{TU}\) forms an arc \(\widehat{TU}\), we can set up the following equation:

\(\widehat{TV}+\widehat{VU}=\widehat{TU}\).

Since arc TU represents half of a circle and there are 360 degrees in a circle, we can substitute the following values and solve for the measure of arc VU:

\(\\2\cdot 30^{\circ}+\widehat{VU}=180^{\circ},\\60^{\circ}+\widehat{VU}=180^{\circ},\\m\widehat{VU}=\boxed{120^{\circ}}\)

Step-by-step explanation:

1. first we need to make an equation we know 15apples plus a block of cheese that costs $2.75 adds up to $6.20 so we would write this as

      15a+2.75=6.20

(the reason we write 15 apples as 15a is because we don't know how much each apple cost but we know there is 15 of them)

2. the aim of the question is to figure out how much each apple cost so we would get a on its own we would do this by -2.75 from each side and divide by 15 to get the coast of each apple

     15a=3.45

(from this we know 15 apples cost 3.45 but we want to know what each apple coast so we divide by 15 on each side)

     a=0.23

so each apple coast 0.23

Since we are given that ΔA'B'C' is formed after a sequence of transformations applied to ΔABC.

The first is a reflection across a line and second is a translation.

The co-ordinates of point C are (-4, -2). After reflection from the line y = x, the co-ordinates becomes  (2, -4).

Also, the coordinates of point C' are (12, 0).

So, to reach point C' from point C, we should add 10 units to the x-coordinate and 4 units to the y-coordinate.

That is, the translation of 10 units right and 4 units up.

Thus, the complete transformation is

The sequence of transformations that maps ∆ABC to ∆A′B′C′ is a reflection across the line y = x followed by a translation 10 units right and 4 units up.

Making the equation false

The value of the smiley face provided in the question is 908.

The first step is to determine the value of each of the shapes.

The value of the rectangle would be determined first. Using the third given equation, let r represent the value of one rectangle.

(4 x r) + (2 x r) - (3 x r) = 15

4r + 2r - 3r = 15

3r = 15

r = 15 / 3 r

r = 5

The next step is to determine the value of the triangle. The second equation would be used. Let t represent the value of the triangle.

(3 x 5) + (4 x t) = 47

15 + 4t = 47

4t = 47 - 15

4t = 32

t = 32 / 4

t = 8

Finally, the value of the star would be determined. Let the value of the star be represented with s. Using the first equation:

5 + (3 x 8) - s = 17

5 + 24 - s = 17

29 - s = 17

s = 29 - 17

s = 12

Now, the value of the smiley face can be determined:

12 x (8  + 12 - 5) + 8(8 . 12 - 5)

12 x (15) + 8(91)

180 + 728 = 908.

What is the rate of change?

The rate of change is also called the slope. On a graph, the rate of change is the ratio of the change in the y-values to the change in the x-values between two data points.

As Carlos has a steady pace and his changes in distance from the lake are constant, his distance graph would be a straight line with a constant slope. On the other hand, Stephanie has a slower rate of change when she turns at the lake. Therefore, her distance graph would be a curve.

Since the graph should show the distance of the two runners from the lake over time, the X-axis should represent time (in minutes), and the Y-axis should represent the distance (in meters).

Based on the given information, the graph that best represents the distance of the two runners from the lake over time is:

Graph C:

In Graph C, the line represents Carlos's distance from the lake, and the curve represents Stephanie's distance from the lake.

The line is straight, indicating that Carlos's rate of change is constant, and the curve shows that Stephanie's rate of change is slower as she turns at the lake.
