A bike tire just ran over a nail and it is losing pressure at a rate of 10% every minute the tire pressure is currently 1464 kPa
SOVA2 [1]

Answer:

Correct answer:  p = 510.465 kPa

Step-by-step explanation:

Initial pressure p = 1,464 kPa

after one minute p₁ = 1,464 · 0.9

after two minutes p₂ = p₁ · 0.9 = (1,464 · 0.9) = 1,464 · 0.9²

after three minutes p₃ = p₂ · 0.9 = (1,464 · 0.9²) · 0.9 = 1,464 · 0.9³

.............................................................

after n minutes  pₙ = 1,464 · 0.9ⁿ

in accordance with the foregoing

after ten minutes p₁₀ = 1,464 · 0.9¹⁰ = 1,464 · 0.3487 = 510.465 kPa

p₁₀ = 510.465 kPa

F(x)=x^2 g(x)=x^2-8 we can think of g as a translated (shifted) version of f
laiz [17]

Answer:

Shift f 8 units down.

Step-by-step explanation:

The complete question is

f(x) =x^2 ,g(x) ​ =x^2-8. ​ We can think of g as a translated (shifted) version of f. Complete the description of the transformation. Use nonnegative numbers. To get the function g, shift f by___ units.

We know that g is obtained by shifting f, k units up or down (depending of the value of k, if positive, the shifting is up, or down otherwise). At any point x, we get g(x) by adding k units to the value of f(x). That is

g(x) = f(x)+k

If we replace the meaning of f,g we get

x^2-8 = x^2

by substracting x^2 on both side we get that k = -8. This means that to get g, we must shift f 8 units down
