Answer:

Step-by-step explanation:

(f• g)(x) = f(x) × g(x)

= $2^{x}$ × (2x - 5)

To evaluate (f • g)(3) , substitute x = 3 into the expression

= 2³ × ( 2(3) - 5)

= 8 × (6 - 5)

= 8 × 1

= 8

Nathan went down to candy world and bought 9 2/3 pounds of lemon drops for him. Nathen gave 5/8 of lemon drops to Darren and Dar

Assoli18 [71]

Answer: $3\dfrac{5}{8}\text{ pounds}$

Step-by-step explanation:

Given : Total amount of candies bought by Nathan $=9\dfrac{2}{3}\text{ pounds}=\dfrac{3\times9+2}{3}\text{ pounds}=\dfrac{29}{3}\text{ pounds}$

Since Nathen gave $\dfrac{5}{8}$ of lemon drops to Darren , the amount of lemon drops Darren got = $\dfrac{5}{8}\times\dfrac{29}{3}=\dfrac{145}{24}\text{ pounds}$

Also, since Darren gave $\dfrac{3}{5}$ of his lemon drops to Mitchel.

The amount of lemon drops Mitchel got = $\dfrac{3}{5}\times\dfrac{145}{24}=\dfrac{29}{8}=3\dfrac{5}{8}\text{ pounds}$

Hence, The amount of lemon drops Mitchel got = $3\dfrac{5}{8}\text{ pounds}$

Nuclear Power Plant Some nuclear power plants utilize "natural draft" cooling towers in the shape of a hyperboloid, a solid obta

luda_lava [24]

Answer:

592.4 feet

Step-by-step explanation:

The cross section of the tower can be modeled by a hyperbola with its vertex at (x, y) = (100, 360) and its center at (0, 360). The point (x, y) = (200, 0) helps define the equation of it.

Basic form:

((x -h)/a)^2 -((y -k)/b)^2 = 1

Filling in (h, k) = (0, 360) and a=100, we can find b using the given point:

(200/100)^2 -((0-360)/b)^2 = 1

(360/b)^2 = 3 . . . . . . . . . . . . . . . rearrange, simplify

b^ = 360^2/3 = 43200

So, the equation of the hyperbola is ...

x^2/10000 - (y-360)^2/43200 = 1

Then for x = 150 (the distance from center at the top, we can find y to be ...

(150/100)^2 - (y -360)^2/43200 = 1

1.25 = (y -360)^2/43200

y = 360 +√(1.25·43200) ≈ 592.379

The height of the tower is about 592.4 feet.
