Answer:

12.60

Step-by-step explanation:

I don't feel like explaining it, since I'm not good at giving detail sorry <3

Step-by-step explanation:

an = A×n² + B×n + C

a1 = -5 = A×1² + B×1 + C = A + B + C

a2 = -4 = A×2² + B×2 + C = 4A + 2B + C

a3 = -1 = A×3² + B×3 + C = 9A + 3B + C

a2 - a1 = -4 - -5 = 1 = 4A+2B+C-A-B-C = 3A + B

3A = 1 - B

A = (1 - B)/3

a3 - a2 = -1 - -4 = 3 = 9A+3B+C-4A-2B-C = 5A + B

3 = 5A + B = 5(1 - B)/3 + B

9 = 5(1 - B) + 3B = 5 - 5B + 3B = 5 - 2B

4 = -2B

B = -4/2 = -2

A = (1 - -2)/3 = (1 + 2)/3 = 3 / 3 = 1

-5 = A+B+C = 1 - 2 + C = -1 + C

-4 = C

so,

an = n² - 2n - 4

Step-by-step explanation:

9514 1404 393

Answer:

  80 tickets

Step-by-step explanation:

Let 'a' represent the number of adult tickets sold. Then a-30 is the number of student tickets sold. The total revenue is ...

  8a +4(a -30) = 840

  12a -120 = 840 . . . . . . eliminate parentheses

  a -10 = 70 . . . . . . . . . divide by 12

  a = 80 . . . . . . . . . . . add 10

The drama class sold 80 adult tickets.

Answer:

449/100

Step-by-step explanation:

1.67 + 2.82 = 4.49

4.49 = 4(0.01) + 49(0.01) = 449(0.01)

Multiplying 449 by 0.01 is the same as dividing 449 by 100

4.49 as fraction = 449/100

Answer:

1/2

Step-by-step explanation:

that's the answer because 2/8-1/4 is 1/2

A projectile is an object launched into space, and moving under the influence of gravity and momentum. The stone here is an example. Thus, the time taken for the stone to reach the ground is 10 seconds.

On launching of the stone into space, it behaves as a projectile. Thus moving under the influence of gravity and its momentum. Its momentum is the product of its mass and velocity.

The height h, is given as:

h = 16[tex]t^{2}[/tex] + 32t + 240

Differentiating the expression with respect to t, we have;

32t + 32 = 0

t = -1 seconds

Substitute the value of time, t, in the equation for the height;

h = 16 - 32 + 240

  = 224

h = 224 m

Total height, S = 240 + 224

                         = 464

S = 464 m

The total height covered by the stone is 464 m.

From the second equation of free fall,

S = Ut + [tex]\frac{1}{2}[/tex]g[tex]t^{2}[/tex]

S = [tex]\frac{1}{2}[/tex]g[tex]t^{2}[/tex]

464 = [tex]\frac{1}{2}[/tex]*9.8*[tex]t^{2}[/tex]

[tex]t^{2}[/tex] = [tex]\frac{928}{9.8}[/tex]

  = 94.694

t = [tex]\sqrt{94.694}[/tex]

 = 9.7311

t ≅ 10 seconds

The time taken for the stone to hit the ground is 10 seconds.

Thus option A is the required answer.

Answer:

Step-by-step explanation:

(fog)(x) = f[g(x)]

(fog)(x) = f[(4/x - 5)]

(fog)(x) = 1 / ((4/x - 5) - 9)

(fog)(x) = 1 / (4/x - 14)

(gof)(x) = g[f(x)]

(gof)(x) = g[1/(x - 9)]

(gof)(x) = (4/ 1/(x - 9)) - 5

(gof)(x) = (4•(x - 9)/1) - 5

(gof)(x) = (4x - 36) - 5

(gof)(x) = 4x - 41

Answer:

5 23/80

Step-by-step explanation:

First, you need to find the least common multiple of 16 and 10 to add the fractions. The LCM of 16 and 10 is 80. You have to multiply 5 to 16 to get 80 and 8 to 10 to get 80, so you also multiply the numerator by those numbers. In the end you would get 4 15/80+1 8/80, which equals 5 23/80.
