10, 7, 4, 1, -2, ...

Which function describes the value of the nth term in the sequence?
A. a(n) = – 3n + 10
B. a (n) = -3n + 13
C. a (n) = 10n
D.a (n) = 15n - 6

Answer:

-4636833600

Step-by-step explanation:

6 x 92 x 10^-3 + 4 x 84 x 10^-2

552 x 10^-3 + 4 x 84 x 10^-2

552 x 1000 = 552,000 +4 = 552,004 x 84 = 46368336 x -100 = -4636833600

Answer:

25.67 ; 25.71 ; 25.79

Step-by-step explanation:

Give the measurement :

25.67 cm, 25.79 cm, and 25.71 cm.

Arrangement of numbers on a line plot is arranged in ascending order ( lowest to highest)

Hence,

25.67 < 25.71 < 25.79

Therefore they will follow the arrangement :

25.67 ; 25.71 ; 25.79

Answer:

5.65685425 i

which is answer choice B

Step-by-step explanation:

Answer:

a) The addition property of equality

b) The division property of equality

Step-by-step explanation:

Here, we want to know the correct step to use

From the given question, to proceed;

All we have to do is to move the value that has a negative value on the left hand side to the right hand side

what accompanies this is the addition of the both terms, on the right hand side

After this, we now proceed to divide the sum by the coefficient of x

Thus, the correct choices are;

a) The addition property of equality

b) The division property of equality

Answer:

Step-by-step explanation:

The only way in which you can truly simplify this is to factor the quantity within parentheses.  Use the quadratic formula for this purpose:

y^2 - 2y + 4 has coefficients {1, -2, 4}.  The discriminant is b^2 - 4ac, which here is (-2)^2 - 4(1)(4), or 4 - 16, or -12.  Since the discriminant is negative, we know that the roots of this quadratic are complex, different:

       -b ± i√(discriminant)

y = ---------------------------------

                    2a

                -(-2) ±i√12          2 ±i2√3)

Then y = ------------------- = ---------------- = 1 ±i√3

                        2                       2

and we end up with these three factors:  x, x - 1 +i√3, x - 1 -i√3

So the original expression becomes -3·y·(y-1i√3)(y - 1 -i√3)

Answer:

38m

Step-by-step explanation:

Area of rectangle = length x breadth

perimeter of a rectangle = 2 x( length + breadth)

The factors of 18 are 1,2, 3,6,9,18

The possible areas and perimeters of the flowerbed based on the factors are

1 x 18 = 18cm^2  Perimeter = 2(1+18) = 38

2 x 9 = 18cm^2  perimeter = 2 (2+9) = 22

3 x 6 = 18cm^2 perimeter = 2 (6 +3) = 18

the greatest is 38m

Answer: x + 10

Step-by-step explanation:

The 10th term of the arithmetic sequence will be:

= a + 9d

where a = 3x + 4

d = x + 10 - (3x + 4)

= x + 10 - 3x - 4

= -2x + 6

Therefore, a + 9d = 3x + 4 + (-2x + 6)

= 3x + 4 - 2x + 6

= 3x - 2x + 4 + 6

= x + 10

Answer:

33 degrees

Step-by-step explanation:

180 - 23 - 124 = 33 because all interior angles of a triangle add up to 180 degrees.

Answer:

5+k = 11

Step-by-step explanation:

"Sum of a number" means addition.

"A number k and five" means you add the variable k and 5

"Is 11" tells you that the answer will be 11

You need to add K and 5 and get 11. Use this to set up an equation. Solve for K if need be. This results in k=6 but i believe that is not part of the prompt. Happy mathing ;)
