Marat540 [252]

Answer:

Volume = 160 cm³   (Unit = cm³)

Step-by-step explanation:

Length = 4 cm

Width = 4 cm  (Because it's a square based cuboid!)

Height = 10 cm

<em><u>Now, Volume:</u></em>

Volume = Length * Width*Height

Volume = 4 * 4 * 10

Volume = 160 cm³

What is the inverse of the function f(x) = 3x - 122
Damm [24]

Answer:

Step-by-step explanation:

y = x/4 - 12

x = y/4 - 12

y/4 - 12 =x

y/4 = x + 12

y = 4x + 48

h(x) = 4x + 48

y = 3x - 122

x = 3y - 122

3y - 122 = x

3y = x + 122

y = x/3 + 122/3

f^-1(x) = x/3 + 122/3

Find the specified vector or scalar. Show your work.
OleMash [197]

We sum vectors by summing the coefficient of corresponding coordinates:

v = ai+bj,\quad w = ci+dj \implies v+w = (a+c)i+(b+d)j

So, in your case, we have

u+v = (-4+4)i + (1+1)j = 0i+2j = 2j

The norm of a vector is the square root of the sum of the squares of its coefficients:

u = ai+bj \implies ||u||=\sqrt{a^2+b^2}

So, in your case, we have

||u+v|| = ||0i+2j|| = \sqrt{0^2+2^2} = \sqrt{4}=2

Jackrabbits are capable of reaching speeds up to 40 miles per hour. How fast is this in feet per second? (Round to the nearest w
Sonja [21]

Answer:

173/3 feet per second

Step-by-step explanation:

So we know that jackrabbits can travel at 40 miles per hour, and we are trying find how fast they can travel in feet per second. To do this, we must first convert the 40 miles per hour into feet per hour:

\frac{40mi}{1hr}*\frac{5280ft}{1mi}=\frac{211200ft}{1hr}

So now we know that 40 miles per hour is equal to 211200 feet per hour. Now we have to convert feet per hour to feet per second. To do this, we must first find the feet per minute (60 min = 1 hr):

\frac{211200ft}{1hr}*\frac{1hr}{60min}=\frac{211200ft}{60min}=\frac{3520ft}{1min}

So now we know that 211200 feet per hour is equal to 3520 feet per minute. Now we have to convert feet per minute into feet per second (60 s = 1 min):

\frac{3520ft}{1min}*\frac{1min}{60s}=\frac{3520ft}{60s}=\frac{176ft}{3s}=\frac{173}{3}ft/s

So now we know that 3520 feet per minute is equal to 173/3 feet per second.

Since 40 miles per hour equals 211200 feet per hour which equals 3520 feet per minute which equals 173/3 feet per second, 40 miles per hour equals 173/3 feet per second.

The jackrabbits can run at 173/3 feet per second.

I hope this helps. :)
