Answer:

The correct option is B.

Step-by-step explanation:

The number of members of an online community increases each month. It is represented by the function

M(t)=N(1+r)^t

Where N is the initial number of members and r is the rate of increase.

The initial value for the function is N, because at t=0 the value of M is N. So, option A is incorrect.

The value of M is product of N and (1+r)^t. The second term is free from N, because second term does not contain N. therefore the second factor does not depend on N. So, option B is correct.

It is an exponential growth function, therefore it can not be linear. So, option C is incorrect.

The initial value is constant. In the given function only the value of t can be changed. So, option D is incorrect.

You are dealt one card from 52 card deck. Find the possibility that you are dealt a heart or a picture card
PIT_PIT [208]

Answer:

<h2>11/26</h2>

Step-by-step explanation:

Since we have 13 heart card then

p(heart) = 13/52

Since we have 12 picture card then

p(picture) = 12/52

Since we have 3 heart and picture (at the same time) card then

p(heart∩picture) = 3/52

finally,

the possibility that you are dealt a heart or a picture card = p(heart or picture)

p(heart or picture) = 13/52 + 12/52 - 3/52 = 22/52

You have an initial amount of $55 in a savings account and you deposit an equal amount into your account each week. After 6 week
bonufazy [111]
Given:
initial deposit = 45
total deposit = 105
w = weekly deposit
x = no. of weeks = 5 weeks
y = amount in dollars
45 + 5w = 105
45 + 5w = 105
5w  = 105 - 45
5w =  60
w = 60/5
w = $12 weekly deposit.

y = $45 + $12x  
<span>x = (y - 45)/12

</span>To check:
y = 45 + 12(5)
y = 45 + 60
y = 105 total deposit in 5 weeks

x = (105-45)/12
x = 60/12
x = 5 weeks

I hope this help
