The number y of hits a new website receives each month can be modeled by y = 4070ekt, where t represents the number of months th

makvit [3.9K]

Answer:

k = 0.2645

Step-by-step explanation:

Given model:

y = 4070 $e^{kt}$

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 $e^{3k}$

$\frac{9000}{4070}$ = $e^{3k}$

$\frac{900}{407}$ = $e^{3k}$

Taking natural logarithm on both sides, we get:

$ln\frac{900}{407}$ = $ln(e^{3k})$

$ln\frac{900}{407}$ = 3k lne

lne=1

$ln \frac{900}{407}$ = 3k

or k = $\frac{1}{3}$ $ln\frac{900}{(407)}$

k = $\frac{1}{3}$ (0.7936)

k = 0.2645

What is the inequality of 5(3-x)-4(2-3x)>2

Aneli [31]

5(3 - x) - 4(2 - 3x) > 2

15 - 5x - 8 + 12x > 2 distributed 5 and 4 on the left side

7 + 7x > 2 added like terms (15 and -8) and (-5x and 12x)

-7 -7

7x > -5

$\frac{7x}{7} > \frac{-5}{7}$

$x > \frac{-5}{7}$

Please help me with this

Tatiana [17]

Answer:

A= 65 in. ^2

Step-by-step explanation:

first make them into different shapes

I made 3 different rectangles

#1 4 by 6

#2 4 by 8

#3 3 by 3

for a area of a rectangles you do base times the height

#1 6*4 = 24

#2 4*8 = 32

#3 3*3 = 9

now you add them up

24+32+9

= 65 in. ^2
