Answer 1

Answer: Choice B

[tex]\frac{1}{\sqrt{65}}<-4, 7>[/tex]

===============================================================

Explanation:

Consider a right triangle with legs a = 4 and b = 7. Through the pythagorean theorem, the hypotenuse is

c = sqrt(a^2+b^2) = sqrt(4^2+7^2) = sqrt(65)

This represents the length of the vector <-4,7>

Dividing each component by the length will normalize the vector. This is the same as multiplying by [tex]\frac{1}{\sqrt{65}}[/tex] which is what choice B shows. The phrasing "normalize the vector" means "make the vector to be of length 1". A common application of normalizing vectors will come up in computer graphics.

The original vector and the vector mentioned in choice B point in the same direction. The only thing that has changed is the length from sqrt(65) to 1.

3. The sum of the second and third terms of a Geometric Progression is 48. If the sum of third and fourth terms is 144, find the first term of the progression.

Answers

Answer:

gọi

Step-by-step explanation:

We have that the  first term of the progression is

b=4

From the Question we are told that

Third terms of a Geometric Progression is 48

Sum of third and fourth terms is 144

[tex]x_3+x_4=144[/tex]

Generally the equation for the common ratio  is mathematically given as

   [tex]\frac{br^2+br^3}{br+br^2}=\frac{144}{48}\\\\\frac{br^2+br^3}{br+br^2}=3[/tex]

  r=3

Therefore

Since

   [tex]br+br^3=48\\\\b(3)+b(3)^3=48[/tex]

  b=4

Given the directed line segment AB: Point A is the _____ with coordinates Point B is the point with coordinates ______.​

Answers

In the given line segment, the coordinates of Point A and Point B is (1, 3) and (4, 6).

What is a line segment?A line segment in geometry is a section of a straight line that is enclosed by two clearly defined endpoints and contains all of the points on the line that lies inside those endpoints. The Euclidean distance between two ends of a line segment determines its length. A square, for instance, is a two-dimensional geometry with four equal-length sides. In a square, all four interior angles are right angles, and the opposing sides are parallel to one another.

So, according to the given image:

Coordinates of point A: (1, 3)Coordinates of point B: (4, 6)

Then, Point B is the point with coordinates (4, 6), while Point A is the line (1, 3).

Therefore, in the given line segment, the coordinates of Point A and Point B is (1, 3) and (4, 6).

Rosa completed her chemistry lab in 35.7 minutes. Dale completed the same lab in 36.5 minutes. Who completed their lab first, Rosa or Dale? A Rosa B Dale ​

Answers

Answer:

A. Rosa

Step-by-step explanation:

Since both measurements of time are using the same units, minutes, we can simply compare them and decide which one is the smallest number. The smallest number represents who took the least amount of time and therefore shows who completed their lab first.

35.7 _ 36.5

35.7 < 36.5

Rosa with 35.7 minutes, completed her lab first.

Answer:

Rosa would have finished first

Step-by-step explanation:

If Rosa finished her chemistry lab in 35.7 minutes and Dale in 36.5 it doesn't matter about the decimal 35 comes before 36 therefore Rosa finished first.

If the 102,619 residents of a city are divided into 57 equal groups, then some residents don’t fit into a group.

How many residents would be in a group?

How many residents would not fit into a group?

Answers

Hey there! Here is your answer:

102,600 would be in a group. 19 would not be in a group.

Step-by-step explanation:

We can figure this out by doing 102,619 divided by 57. This gives us:

1,800 R 19

Now we need to multiply 1800 by 57 to see how many residents there are:

1,800 x 57 = 102,600

Our remainder tells us how many residents would not fit into a group. Since our remainder is 19, 19 would not be in a group.

I hope this helps!

Write each decimal as a percent and a fraction -0.04

Answers

Answer:

-4%   -1/25

Step-by-step explanation:

To convert a decimal to a percentage, multiply it by 100.

-0.04 * 100 = -4

To convert a decimal to a fraction, put the decimal as a fraction over 1 and multiply until the numerator (top number) is a whole number and then simplify.

[tex]\frac{-0.04}{1}[/tex] x [tex]\frac{100}{100}[/tex] = [tex]\frac{-4}{100}[/tex]

-4/100 simplified = -1/25 (because 4 goes into 100 25 times)

Two functions are always equivalent if their graphical representations are the same.

What is a function?

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The collection includes all locations on the surface of the shape (x, f(x)) that make up a function of f's graph. We may alternatively say that the graph of f is the curve of y = f. (x). As a result, the diagram of an equation is a particular instance of the graphs of functions.

Two functions are always equivalent if their graphical representations are the same.
