Answer:

a ≈ 1.8

Step-by-step explanation:

a / sin (180 - 105 - 15)° = 2 /sin 105°

a = (2 /sin 105°) x sin 60°

a = (2 / 0.97) x 0.87

a = 1.79    (≈ 1.8)

Answer:

5x^3-2x^2+2x+9

Step-by-step explanation:

(5x^3+4x^2)−(6x^2−2x−9)

To find the opposite of 6x^2−2x−9 find the opposite of each term.

5x^3+4x^2−6x^2+2x+9

Combine 4x^2 and 6x^2 to get −2x^2.

5x^3-2x^2+2x+9

The number N of cars produced at a certain factory in 1 day after t hours of operation is given by Upper N (t )equals 800 t minu
Elden [556K]

Answer:

The cost C as a function of t is C(t) = 30,000 + 6,400,000 t - 40,000 t²

Step-by-step explanation:

The function N(t) = 800 t -  5t², represents the number of cars produced at a time t hours in a day, where 0 ≤ t ≤ 10

The function C(N) = 30,000 + 8,000 N, represents the cost C​ (in dollars) of producing N cars

We need to find The cost C as a function of the time t

That means Substitute N in C by its function by other word find the composite function (C о N)(t)

∵ C(N) = 30,000 + 8,000 N

∵ N(t) = 800 t - 5 t²

- Substitute N in C by 800 t - 5 t²

∴ C(N(t)) = 30,000 + 8000(800 t - 5 t²)

- Multiply the bracket by 8000

∴ C(N(t)) = 30,000 + 8000(800 t) - 8000(5 t²)

∴ C(N(t)) = 30,000 + 6,400,000 t - 40,000 t²

- C(N(t) = C(t)

∴ C(t) = 30,000 + 6,400,000 t - 40,000 t²

The cost C as a function of t is C(t) = 30,000 + 6,400,000 t - 40,000 t²

WILL NAME brainliest
kolezko [41]

Answer:

x=13

Step-by-step explanation:

By the definition of an angle bisector, we have that 8x-23=5x+16.

We can add 23 to both sides to get 8x=5x+39.

We can then subtract 5x from both sides to get 3x=39.

We can finally divide both sides by 3 to get \boxed{x=13}
