Find the magnitude of the vector from the origin to (-7,5) and write the vector as the sum of unit vectors.

Answer:

First Picture: 2032*93 = 188976, 425/25 = 17

Second Picture: the machine is dividing the number by 6

Third picture: 85

Step-by-step explanation:

Second Picture: 36/6 = 6 and 54/9 = 6 therefore the machine is dividing by six

Third Picture: a multiple of 7 is 84 (7*12 = 84). 85 is one more than a multiple of 7. Therefore 85 is the answer. A formula can be 7x + 1 = (then try out different numbers in the grid)

7x+1 = 85

7x = 84

x = 84/7

x = 12

Therefore 85 is one more than a multiple of 7.

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Answer:

\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)

Step-by-step explanation:

Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.

\(A = \frac{h_{b}+b}{2}\)

Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.

By using trigonometric relations we will see that the area is:

How to find the area of one triangular section?

Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.

Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).

h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:

tan(60°) = x/h

x = tan(60°)*h

Then our two catheti are h and tan(60°)*h.

This means that the area will be:

Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

Answer:

A. EAJ and IAH

Step-by-step explanation:

The answer is A. EAJ and IAH because if you notice, angle "EAJ" starts at "E", goes down to "A", and to the right to "J". Now, if you would again notice, angle "IAH" stars at "I", goes up to "A", and to the left to "H".

The definition of a verticle angle are angles opposite each other where two lines cross.

I have attacked an image below of an example of a verticle angle. If you would notice, the image of the vertical angle I attached looks the same as option "A. EAJ and IAH".

The image vertices of L′M′N′ if the preimage is rotated 90° clockwise are,

⇒ L′(- 1, 4), M′(-1, 0), N′(- 3, 4)

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

Triangle LMN is drawn with vertices at L(−4, −1), M(0, −1), N(−4, −3).

Now, We know that;

The rule of rotation 90° clockwise is,

⇒ (x, y) = (y, - x)

Thus, We get;

L = (- 4, - 1)

L'= (- 1,  4)

M = (0, - 1)

M' = (- 1, 0)

N = (- 4, - 3)

N' = (- 3, 4)

Hence, The image vertices of L′M′N′ if the preimage is rotated 90° clockwise are,

⇒ L′(- 1, 4), M′(-1, 0), N′(- 3, 4)

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Answer: 2x + 4x = (2 + 4)x = 6x

Step-by-step explanation:

The expression 2x + 4x represents the cost of buying the same number of cases of spring water and sparkling water. To express the total cost, we need to add the cost of buying the two types of water.

Since the expression 2x represents the cost of buying x cases of spring water, and 4x represents the cost of buying x cases of sparkling water, the total cost can be expressed as:

2x + 4x = (2 + 4)x = 6x

Therefore, the total cost of buying x cases of spring water and sparkling water can be expressed as 6x.

Alternatively, you can think of it as buying x cases of spring water at a cost of 2x dollars and x cases of sparkling water at a cost of 4x dollars. So the total cost is (2x+4x) dollars which is 6x dollars.

Answer:

\( a=1.58, \: \: a =-7.58\)

Step-by-step explanation:

Since, circle of center (-3 , -2) is passing through the points (0 , -6) and (a , 0).

Therefore, points (0 , -6) and (a , 0) will be equidistant from the center of the circle (-3 , -2).

Hence,

Distance between (0 , -6) and (-3 , -2) = Distance between (a , 0) and (-3 , -2).

\( [0-(-3)]^2 + [-6-(-2)]^2=[a-(-3)]^2 + [0-(-2)]^2\)

\( [0+3]^2 + [-6+2]^2=[a+3]^2 + [0+2]^2\)

\( [3]^2 + [-4]^2=[a+3]^2 + [2]^2\)

\( 9 + 16=[a+3]^2 + 4\)

\( 25=[a+3]^2 + 4\)

\( 25-4=[a+3]^2\)

\( 21=[a+3]^2\)

\( [a+3]^2=21\)

\( [a+3]=\pm\sqrt {21} \)

\( a=\pm\sqrt {21} - 3\)

\( a=\sqrt {21} - 3, \: \: a =-\sqrt {21} - 3\)

\( a=1.58257569, \: \: a =-7.58257569\)

\( a=1.58, \: \: a =-7.58\)

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A
