Determine the value of x to the nearest thousandth in the equation 8(2)^x+3=48

solong [7]

You probably mean either

$8\cdot2^x + 3 = 48$

$8\cdot2^{x+3} = 48$

Write 8 = 2³, so that in the first interpretation,

$8\cdot2^x = 2^3 \cdot 2^x = 2^{x + 3}$

and in the second,

$8\cdot2^{x+3} = 2^3 \cdot 2^{x+3} = 2^{x + 6}$

Then in the first interpretation, we have

$2^{x + 3} + 3 = 48 \implies 2^{x + 3} = 45 \implies x + 3 = \log_2(45) \implies x = \log_2(45) - 3 \approx \boxed{2.492}$

Otherwise, the second interpretation gives

$2^{x + 6} = 48 \implies x + 6 = \log_2(48) \implies x = \log_2(48) - 6 \approx -0.415$

The height of a ball in meters is modeled by f(x) equals negative 5X squared +50 X where X is the time in seconds after it is hi

luda_lava [24]

Answer:

10 seconds

Step-by-step explanation:

Find the zeros by equating f(x) to zero, that is

- 5x² + 50x = 0 ← factor out - 5x from each term

- 5x(x - 10) = 0

Equate each factor to zero and solve for x

- 5x = 0 ⇒ x = 0

x - 10 = 0 ⇒ x = 10

x = 0 denotes the time when the ball is struck and x = 10 when the ball returns to the ground.

Time in air = 10 - 0 = 10 seconds
