Answer:

sqrt(5)

Step-by-step explanation:

Honestly think this person means to find the magnitude of the vector.  You can use dot product here, the vector with itself... But that isn't the last step.

v dot v=4+1=5

and so |v|=sqrt(5)

One side of a rectangle is three times as long as another. If its area is 363 square centimeters, find its dimensions.
Yakvenalex [24]

9514 1404 393

Answer:

  11 cm by 33 cm

Step-by-step explanation:

You can solve this problem mentally as follows.

Consider the rectangle as 3 squares, side-by-side. Then the area of each of those squares is 363/3 = 121 cm^2. From your knowledge of the squares of numbers, you know that 121 = 11^2. So, the width of the rectangle is 11 cm, and the length is 3 times that, or 33 cm.

_____

Using variables, we can let w represent the width. Then 3w can represent the length, and the area is ...

  A = LW

  A = (3w)(w) = 3x^2 = 363

  w^2 = 363/3 = 121

  w = √121 = 11

  3w = 3·11 = 33

The width is 11 cm; the length is 33 cm.

Help me pls

Answer:

We know that Amber decided to mail copies of her photo to the 45 residents of her grandmother's assisted living facility, and after this, the function representing the photo shares is:

f(x) = 3*(4)^x + 45

We do not know the initial function, but with the given information we can assume that the original equation is:

g(x) = 3*(4)^x

Then the new function is:

f(x) = g(x) + 45.

This is a vertical translation, remember that for a function h(x), a vertical translation of N units is written as:

k(x) = h(x) + N

if N is positive, we have a translation of N units up

if N is negative, we have a translation of N units down.

in this case we have;

f(x) = g(x) + 45

This means that f(x) is a vertical translation of 45 units of g(x), then:

the graph of the new function is 45 units above the original function.
