Debora [2.8K]3 years ago
4 0

Answer:

Step-by-step explanation:

a1 = 7

a2 = 4(7) = 28

a3 = 4(28) = 112

a4 = 4(112) = 448

a5 = 4(448) = 1792

a6 = 4(1792) = 7168

Employees at a company are given a three digit employee identification code. If each digit cannot be repeated, how many differen
Papessa [141]
720 codes.



There are 10 digits possible for the first digit of the code.

Since there can be no repeated digits, you subtract 1 and find there are only 9 possible digits for the second digit in the code.

Finally, subtract 1 again to find there are only 8 possible digits for the last digit.

Multiply these together to find the number of combinations.

10 * 9 * 8

90 * 8

720

So, there are 720 combinations if digits cannot be repeated.

Use the distributive property to simplify the expression.
horrorfan [7]

\huge\mathbb{ \underline{SOLUTION :}}

<h3>Given:</h3>
  • \bold{-6(2^2+3)-2(1^2-2)}

\\

The \mathrm{distributive \: property} states that an expression that is given in the form of \small\sf{ A(B + C)} can be solved as \small\sf{A \times (B + C) = AB + AC} . So:

\small\longrightarrow\sf{-24-18-2+4}

\small\longrightarrow\sf{-42+2}

▪ \large\tt{All \:  \: options \: \: are \: \: wrong}

\\

\huge \mathbb{ \underline{ANSWER:}}

\small\longrightarrow\sf{−6 (2^2+3) − 2 (1^2 - 2) = \underline{-6(4+3)}}

Could someone please explain how to solve for the area?
aniked [119]

9514 1404 393

Answer:

  280.6 square units

Step-by-step explanation:

The formula for the area of an n-gon with radius r is useful here:

  A = (n/2)r²sin(360°/n)

For your hexagon (n=6) with radius r=6√3, the area is ...

  A = (6/2)(6√3)²sin(360°/6) = 324sin(60°) = 162√3 ≈ 280.6 . . . square units

The area of the poster is (x^2+2x-15) inches the width is (x-3) inches calculate the dimensions of the poster board when x=14
givi [52]

Answer:

The poster is 11 inches wide and 19 inches in height.

Step-by-step explanation:

We take the given equation: (x^2+2x-15) and we add in 14 as our x variable:

((14)^2+2(14)-15) the answer we get from that is 209. The area of the poster is 209 square inches. Then we find the width by taking (x-3) in this case x is 14 so the width of the poster is 11. In order to find the height we divide the height by the width and we get 19.

Therefore:

Height= 19 Inches

Width= 11 Inches

Total Area= 209 Square Inches
