Find the limit as limit x-->infinity (e^-2x)*cosx.

1 answer:

3 0

We are asked to evaluate the limit of (e^-2x)*cosx as x approaches infinity. we can rewrite the equation into cos x / e ^2x. we substitute x with infinity. This is equal to 1/infinity. a number divided by infinity is equal to zero. Hence the answer to this problem is zero

A cylinder has a circular base with a diameter of 12 ft the height of the cylinder is 4 feet what is the volume of the cylinder

Murrr4er [49]

Answer:

$452\ ft^{3}$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

we have

$r=12/2=6\ ft$ ----> the radius is half the diameter

$h=4\ ft$

substitute the values

$V=(3.14)(6^{2})(4)=452\ ft^{3}$

Use the relationship between the

The equation x° = 180° - (37°+ 53°) can be used to find the value of x.

Step-by-step explanation:

Step 1; There are three lines in the given diagram. There are a baseline and two other lines. Out of the other two lines, one extends above and below the baseline whereas the other extends only above. Since the baseline is horizontal and the others are at angles we have the sum of all the three angles as 180° i.e. 37°, x°, and 53°.

37° + x° + 53° = 180°.

Step 2; To solve the value of x, we keep the unknown value at the left-hand side whereas all the known values are taken to the right side of the equation.

x° = 180° - (37°+ 53°).

So the fifth option can be used to determine the value of x.

The Jackson family drove 496 miles in 8 hours. Which is the unit rate in fraction form?

vagabundo [1.1K]

You find the unit rate by dividing 496 by 8
so
$\frac{496}{8} = \frac{62}{1}$
