Answer:

2. there are 6 tens and 5 ones.

3. The total value of the coins = 52. This is the answer because you can count 5 dimes and 2 pennies. A dime is worth 10 cents, so 10 x 5 = 50. A penney is worth one cent. 1 x 2 = 2. 50 + 2 = 52

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.

Simplify as far as possible.<br>1<br>3cos (180° + x)sin (360° - X)<br>sin (360° + x)cos (180° - x)​
KengaRu [80]

Answer:

See below

Step-by-step explanation:

cos (180 + x) = - cos x

sin (360 + x) = sin x

sin 360 - x) = -sin x

cos (180 - x) = - cos x

3cos (180° + x)sin (360° - X) = -3cos x (- sin x) = 3 cosx sinx

sin (360° + x)cos (180° - x)​ = sin x (- cos x) = -sinx cosx

3cos (180° + x)sin (360° - X)sin (360° + x)cos (180° - x)​

= 3 cosx sinx (-sinx cosx) = -3 (sin x)^2 (cos x)^2

I am not sure what the question really is, but hopefully the above can steer you in the right direction.
