A submarine travels through the water at an elevation of - 203 meters (it travels below the surface). The sub starts to rise. Th

e elevation changes by 4.3 meters per minute for the first 15 minutes. The sub continues to rise at 5.2 meters per minute for the next 12 minutes. What is the elevation of the submarine after it has been rising for 27 minutes? Assume that sea level is at an elevation of 0 feet.

Well see here that it practically gives us the answer. The submarine rises 4.3 meter each minute of the first 15 minutes. Multiplying these two given numbers you get 64.5  . Great we're halfway through. Now onto the second equation. 5.2 times 12 . easy right? The answer round to 62.4 . Now all that's left to do is add the two together. After the 27 minutes the submarine should be at an elevation of 126.9 feet. rounding to 127 if you teacher requires you to round the numbers.

Find the inverse f^-1(x) if f(x)=x+2
stiks02 [169]

Answer:

f^-1(x) = x - 2

Step-by-step explanation:

To find the inverse of a function in terms of x and y, you would sway x and y in the function. We can rewrite f(x) = x + 2 as y = x + 2, since f(x) is basically y in a function. The inverse of y = x + 2 would be x = y + 2. Now, solve for y.

x = y + 2

-2 both sides.

x - 2 = y

y = x - 2

The inverse of y = x + 2 would be y = x - 2, so the inverse of f(x) = x + 2 would be f^-1(x) = x - 2 (f^-1(x) means the inverse of f(x)).

f^-1(x) = x - 2

I hope you find this helpful. :)

What is...a increased by 25%
Gelneren [198K]

Answer:

  1..25a

Step-by-step explanation:

a + 25%·a = a(1 + 0.25) = 1.25a

_____

<em>Comment on percentages</em>

The symbol "%" is a shorthand way to write "/100", so 25% = 25/100 = 0.25.

Of course, 100/100 = 100% = 1.

Adding 25% of something to 100% of it gives 125% of it, the original amount multiplied by 125/100 = 1.25.

PRECALC HELP<br> please help with the image above (translation up and down)
garik1379 [7]

Answer:

fourth option

Step-by-step explanation:

Given f(x) then f(x + a) represents a horizontal translation of f(x)

• If a > 0 then a shift left of a units

• If a < 0 then a shift right of a units

Thus

f(x) = (x - 11)³ ← has been translated right by 11 units

Given f(x) then f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Thus

f(x) = (x - 11)³ + 4

represents a translation 11 units right and 4 units up
