Answer:

$6 (6x^{2} - 4x - 3)$

Step-by-step explanation:

$36x^{2} - 24x - 18$

$= 6 (6x^{2}) - 6 (4x) - 6(3)$

$= 6 (6x^{2} - 4x - 3)$

Answer:

6(6x^2-4x-3)

Step-by-step explanation:

A blimp is 1600 meters high in the air and measures the angles of depression to two stadiums to the east of the blimp. if those

Sonja [21]

The two stadiums are 2,871 meters

A blimp = point A

stadium 1 = point B

stadium 2 = point C

height of the blimp , AD = 1600

depression angle of stadium 1 , ∠y = 71.7°

depression angle of stadium 2 , ∠x = 25.2°

distance between the two stadiums = d

So, it forms 2 triangles ABD and ACD,

Using the trigonometric ratios,

tan θ = Altitude / Base

DC = AD × tan (90° - x)

= 1600 × tan( 90° - 25.2° )

= 1600 × cot(25.2°)

= 1600 × 2.13

DB = AD × tan (90° - y)

= 1600 × tan( 90° - 71.7° )

= 1600 × cot(71.7°)

= 1600 × 0.33

∴ d = DC - DB

= 1600 * [ tan( 90° - 25.2° ) - tan( 90° - 71.7° ) ]

= 2,871 meters

The range of the function f(k) = k2 + 2k + 1 is {25, 64}. What is the function’s domain?

s344n2d4d5 [400]

{k^2 + 2k + 1 = 25, k^2 + 2k + 1 = 64}
{k^2 + 2k - 24 = 0, k^2 + 2k - 63 = 0}
{(k - 4)(k + 6) = 0, (k - 7)(k + 9) = 0}
{k = -6, 4, -9, 7)
Therefore, range = {-9, -6, 4, 7)

A video game sets the points needed to reach the next level based on the function g(x) = 7(3)^(x − 1), where x is the current le

AleksandrR [38]

Good morning.

In level 4, the experience needed is:

$\mathsf{g(4) = 7\cdot3^{4-1}}\\ \\ \mathsf{g(4) = 7\cdot3^3 = 7\cdot27}\\ \\ \mathsf{g(4) = 189}$

In the hardest settings, the multiplier is:

$\mathsf{h(4) = 4\cdot 4}\\ \\ \mathsf{h(4) = 16}$

So, the adjusted experience points are: multiplier . base experience

$\mathsf{E(x) = h(x)g(x)}\\ \\ \mathsf{E(4) = h(4)g(4) = 16\cdot 189}\\ \\ \boxed{\mathsf{E(4) = 3024 \ points}}$
