The two functions below are used to represent the height of a rocket above the ground after it is launched. Which rocket reaches

Korvikt [17]

Answer:

Rocket B reaches a maximum height that is greater than the maximum height of Rocket A.

Step-by-step explanation:

A graph quickly shows the answer to this question.

In vertex form, the equation for Rocket A is ...

y = -6(x² -16x +8²) +6(8²)

y = -6(x -8)² +384 . . . . . . . . . maximum height is 384 feet

The corresponding equation for Rocket B is ...

y = -4(x² -20x +10²) +4(10²)

y = -4(x -10)² +400 . . . . . . . . maximum height is 400 feet

Rocket B reaches a maximum height greater than that of Rocket A.

What is the solution of the equation 14^x=5? Round your answer to the nearest ten-thousandth.

deff fn [24]

Take ln to both sides
ln 14^x = ln 5
then you'll get
x ln 14 = ln 5
divide both sides by ln 14
x = 0.6098533345
after rounding
x = 0.6099

good morning,

Answer:

10×(1-0.2ⁿ)

Step-by-step explanation:

1.6/8=0.2

0.32/1.6=0.2

0.064/0.32=0.2

let S represent the sum of n term then S=8×[(1-0.2ⁿ)/(1-0.2)] = 10×(1-0.2ⁿ).
