Any of a number of on-line, spreadsheet, or calculator tools will find the matrix product for you.

The input and output of one such tool is shown below.

__

As you know, each term in the product matrix is the sum of products of a row in the left matrix and a column in the right matrix. The coordinates of that row and column are the coordinates of the result in the product matrix.

For example, row 2, column 1 of the product matrix is the sum of products ...

A large jar contains 500 marbles. All of the marbles in the jar are either blue or yellow, and there are 3 times as many blue marbles as yellow marbles. Which equation can be solved to find the number of yellow marbles in the jar?

Answers

Answer:

The equation to solve to find the number of yellow marbles =

3y + y = 500

4y = 500

The number of yellow marbles = 125

Step-by-step explanation:

Let the number of

Blue marbles = x

Yellow marbles = y

A large jar contains 500 marbles.

x + y = 500

All of the marbles in the jar are either blue or yellow, and there are 3 times as many blue marbles as yellow marbles.

3y = x

Hence, we substitute 3y for ymx in the above equation

3y + y = 500

4y = 500

y = 500/4

y = 125

The number of yellow marbles = 125

if a trail runner zig-zags 15m to the west and then 15m to the east:

what is the runner's total distance?
what is the runner's total displacement?​

Answers

Answer:

Total distance = 30m

Total displacement = 0m

Step-by-step explanation:

a) Distance is a scalar quantity that does not specify direction

Hence if a trail runner zig-zags 15m to the west and then 15m to the east, the total distance will be the sum of the distance travelled both to the west and east.

total distance =  distance through west + distance through east

total distance = 15m + 15m

total distance = 30m

Hence the runner's total distance is 30m

b) Displacement is a vector quantity and it specifies direction. Hence we will take into consideration the direction taken

Since East direction is positive, the displacement through east is +15m

Since West direction is negative, the displacement through west is -15m

Total displacement  = +15 - 15

Total displacement = 0m

Hence the runner's total displacement is 0m

Describe the sequence of transformations that maps PQR into P'Q'R' use the drop-down menus to explain your answer

Answers

Answer:

Rotation of 180° clockwise around the origin

Step-by-step explanation: if you rotate the first triangle 90 degrees, it will be in the lower quarter, so you need to rotate it 1 more time.

The transformations are clockwise rotation 180° and translation down by 1 unit.

What is rotation?

Rotations are transformations that turn a shape around a fixed point. To rotate a shape we need: a centre of rotation. an angle of rotation (given in degrees) a direction of rotation – either clockwise or anti-clockwise.

From the given graph, the coordinates of triangle PQR are P(2, 1), Q(4, 6) and R(4, 1).

Rotating a point that has the coordinates (x,y) 180° about the origin in a clockwise direction, we have (-x,-y).

Here,

P(2, 1) → P'(-2, -1)

Q(4, 6) → Q'(-4, -6)

R(4, 1) → R'(-4, -1)

The translation down by 1 unit, we get (x, y-k)

P'(-2, -1) → P'(-2, -2)

Q'(-4, -6) → Q'(-4, -7)

R'(-4, -1) → R'(-4, -2)

The coordinates of triangle P'Q'R' are P'(-2, -2), Q(-4, -7) and R'(-4, -2)

Therefore, the transformations are clockwise rotation 180° and translation down by 1 unit.

In △PQS, m∠Q=22°, m∠S=65°, and s=176. Identify q rounded to the nearest tenth.

Answers

So you would use law of sines to find q

So, sin(22)/q = sin(65)/176

(176sin(22)) / sin(65) = q

q = 72.7465

Rounded to the nearest tenth would be
72.7

So the last answer choice

Using the law of sines, the value of q is: D. 72.7.

What is the Law of Sines?

The law of sines is given as: sin A/a = sin B/b = sin C/c.

Thus, given △PQS, where:

m∠Q = 22°

m∠S = 65°

s = 176

Applying the law of sines, we have:

sin Q/q = sin S/s

Substitute

sin 22/q = sin 65/176

q = (sin 22 × 176)/sin 65

q = 72.7

Therefore, using the law of sines, the value of q is: D. 72.7.

Using the BODMAS rule, the value of the expression  (4+7x2 –8) is 10.

What is BODMAS?

BODMAS is a system that decides the preference of mathematical operations to solve an expression.

B stands for Bracket

O stands for of

D stands for division

M stands for multiplication

A stands for addition

S stands for subtraction.

So,  In the given expression (4 + 7 x 2 – 8) first, we will do multiplication

i.e. 4+14-8

Secondly, we will do the addition

i.e. 18-8

Lastly, we will subtract
