A computer store decides to increase the prices of all the items it sells by 15%. the store manager uses matrices to prepare the
Andrews [41]

The matrix exists as a set of numbers placed in rows and columns to create a rectangular array. The manager could achieve scalar multiplication on Matrix A, utilizing the scalar 1.15.

<h3>What is the matrix?</h3>

The matrix exists as a set of numbers placed in rows and columns to create a rectangular array. The numbers exist named the elements, or entries, of the matrix. Matrices contain wide applications in engineering, physics, economics, and statistics as well as in different branches of mathematics.

Increasing the price by 15% would mean we exist taking 100% of the value + another 15%

100 + 15 = 115%

115% = 115/100 = 1.15.

Multiplying every value in Matrix A by 1.15 will give the price raised by 15%.

Therefore, the correct answer is option c. by multiplying each entry of matrix a by 1.15.

The population of Rock Springs is growing at a constant rate. The expression represents the increase in population in x years. 4
shusha [124]
The expression is given such as:
45, 200 + 1900x

We are asked to solve for the initial production, which means we have x = 0
The solution is shown below:
45, 200 + 1900*0
= 45,200 +0
=45, 200

The answer is letter "C" 45, 000.

What’s the answer please
Stells [14]

Answer:

The length of LK is 52 units.

Step-by-step explanation:

According to the Euclidean Geometry, if two triangles are similar, then every pair of respective sides are proportional and reports the same ratio. In this case, we construct the following formula:

\frac{LM}{LJ} = \frac{LN}{LK} (1)

If we know that LJ = 39, LM = 21 and LN = 28, then the length of LK is:

LK = \frac{LJ\times LN}{LM}

LK = \frac{39\times 28}{21}

LK = 52

The length of LK is 52 units.

6) use the steps to solve this system of equations. Show your work.<br><br> Y=x+2 Y=x^2-4
zepelin [54]

y= x + 2 and  y = x^2 - 4

Substitute mx + b for y

x^2 - 4 = x + 2

Solve for x

x^2 - 4 = x + 2

x^2 - x - 6 = 0

(x - 3)(x + 2) = 0

x - 3 = 0; x = 3

x + 2 = 0; x = -2

Substitute the first x value  into the linear equation and solve for y

y = 3 + 2

y = 5

One solution is (3, 5)

Substitute the second x value into the  linear equation and solve for y

y = -2 + 2

y = 0

Another solution is (-2 , 0)
