Let f(x)=14/7+2e^−0.6x . What is f(3) ? Enter your answer, rounded to the nearest tenth, in the box.
Gelneren [198K]

Answer:

f(3)=1.9

Step-by-step explanation:

we have

f(x)=\frac{14}{7+2e^{-0.6x}}

we know that

f(3) is the value of the function for the value of x equal to 3

so

substitute the value of x=3 in the function

f(3)=\frac{14}{7+2e^{-0.6(3)}}=1.9

For f(x) = 2x+1 and g(x) = 3x-7, find (f-g)(x)
marissa [1.9K]

Answer:

(f - g)(x) = -x + 8

General Formulas and Concepts:

  • Order of Operations: BPEMDAS

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 2x + 1

g(x) = 3x - 7

(f - g)(x) = f(x) - g(x)

<u>Step 2: Simplify</u>

  1. Set up:                              (f - g)(x) = (2x + 1) - (3x - 7)
  2. Distribute -1:                     (f - g)(x) = 2x + 1 - 3x + 7
  3. Combine like terms:        (f - g)(x) = -x + 8

A cannon ball is launched at 6 feet per second from the top of a platform 12 feet above the ground.
AleksAgata [21]
A.) y = ut - 1/2gt^2 + 12
y = 6t - 1/2(9.8)t^2 + 12
y = 6t - 4.9t^2 + 12

b.) The y-intercept is 12

c.) The y-intercept represent the height of the ball at time t = 0

d.) At the time the ball reaches the ground, y = 0
-4.9t^2 + 6t + 12 = 0
t = 2.29 seconds
Therefore, it took the ball 2.29 seconds to reach the ground.
