What is the nth term of this number sequence 25, 20, 15, 10, 5
Please answer it

Answers

Answer 1

Answer:

[tex]a_{n}[/tex] = 30 - 5n

Step-by-step explanation:

There is a common difference between consecutive terms, that is

20 - 25 = 15 - 20 = 15 - 20 = 10 - 15 = 5 - 10 = - 5

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 25 and d = - 5, thus

[tex]a_{n}[/tex] = 25 - 5(n - 1)

    = 25 - 5n + 5

    = 30 - 5n

Is(0,-2) a solution of x+y=6

Answers

Answer:

no

Step-by-step explanation:

x+y=6

Substitute the point into the equation and see if it is true

0 + -2 = 6

-2 =6

This is not true so the point is not a solution

Answer: No

Step-by-step explanation:

To see if (0.-2) is a solution of x+y=6, we can plug it in and solve.

0+(-2)=6            [add]

-2≠6

Since -2 does not equal 6, we know that (0,-2) is not a solution.

What is the coordinate of the midpoint of DA?
D

Answers

Answer:

6

Step-by-step explanation:

Coordinate of point D = -6

Coordinate of point A = 18

The coordinate of the midpoint of DA = the coordinate of the point that is half the distance from D to A.

Distance of DA = |18 -(-6)| = |18 + 6| = 24

Midpoint = ½ the distance of DA = ½*24 = 12

Coordinate of the midpoint of DA = coordinate of D + 12 = -6 + 12 = 6

Or,

Coordinate of A - 12 = 18 - 12 = 6

Therefore, coordinate of the midpoint of DA = 6.

What is h(x) = f(x)g(x)?
O h(x) = 6x2 – 10x - 4
O h(x) = 6x2 – 12x - 4
O h(x) = 6x2 + 2x - 4
O h(x) = 6x2 + 14x + 4

Answers

Answer:

A. h(x) = 6x2 – 10x – 4

Step-by-step explanation:

Got 100% on edge.

The value of h(x) is h(x) = 6x^2 -10x + 4

How to determine the composite function?

The functions are given as:

f(x) = 2x - 4

g(x) = 3x + 1

So, we have:

h(x) = f(x)g(x)

This gives

h(x) = (2x - 4) * (3x+ 1)

Evaluate

h(x) = 6x^2 + 2x - 12x - 4

This gives

h(x) = 6x^2 -10x + 4

Hence, the value of h(x) is h(x) = 6x^2 -10x + 4

Answers

Answer:

Total variable costs for the summer at each price:

a. = $10,185

b. = $5,820

c. = $1,455

Step-by-step explanation:

a. 35 lawns per week x 12 weeks x $24.25 variable cost

= 35 * 12 * $24.25

= $10,185

b. 20 lawns per week x 12 weeks x $24.25 variable cost

= 20 * 12 * $24.25

= $5,820

c. 5 lawns per week x 12 weeks x $24.25 variable cost

= 5 * 12 * $24.25

= $1,455

d. The variable cost, as can be seen from above, changes based on the volume of activity or production.  The number of lawns influenced the cost, since the other indexes are the same in each case.
