Answer:
<u><em>k = 0.2645</em></u>
Step-by-step explanation:
Given model:
y = 4070 
y = no. of hits website received = 9000 (in 3rd month)
t= no. of months website has been operational = 3
put in the above equation:
9000 = 4070 
= 
=
<u><em>Taking natural logarithm on both sides, we get:</em></u>
=
= 3k ln<em>e</em>
ln<em>e</em>=1
= 3k
or k = 

k =
(0.7936)
<em>k = 0.2645</em>

Answer:
Please check the explanation.
Step-by-step explanation:
Let us consider

To find the area under the curve
between
and
, all we need is to integrate
between the limits of
and
.
For example, the area between the curve y = x² - 4 and the x-axis on an interval [2, -2] can be calculated as:

=


solving


![=\left[\frac{x^{2+1}}{2+1}\right]^2_{-2}](https://tex.z-dn.net/?f=%3D%5Cleft%5B%5Cfrac%7Bx%5E%7B2%2B1%7D%7D%7B2%2B1%7D%5Cright%5D%5E2_%7B-2%7D)
![=\left[\frac{x^3}{3}\right]^2_{-2}](https://tex.z-dn.net/?f=%3D%5Cleft%5B%5Cfrac%7Bx%5E3%7D%7B3%7D%5Cright%5D%5E2_%7B-2%7D)
computing the boundaries

Thus,

similarly solving


![=\left[4x\right]^2_{-2}](https://tex.z-dn.net/?f=%3D%5Cleft%5B4x%5Cright%5D%5E2_%7B-2%7D)
computing the boundaries

Thus,

Therefore, the expression becomes



square units
Thus, the area under a curve is -10.67 square units
The area is negative because it is below the x-axis. Please check the attached figure.
Answer:
22°
Step-by-step explanation:
this is a right angle. right angles = 90°. you can now subtract 90-68 to give you 22.
Answer:
there would be 67.2 in 2 containers
Step-by-step explanation:
if you take 672 and divide that by 5 you get 134.4 so if you take that number and divide it by 2 you would get 67.2 hope this helps
