Answer:

plan 1: y=3x+50

plan 2: y=10x

Step-by-step explanation:

for plan 1, since she would have to pay $3 per visit and x is the visits per month, than you would calculate the total cost per visits by 3x. and since there is a starting fee of $50, the total goes up from 50 and never below, therefore 50 is the y-intercept

plan 2, its the same thing as plan 1 but instead of $3 per visit it is $10 and there is no starting fee, so no y-intercept

Plan 1: 50= 1x+3
Plan 2: 10=1x+b
(X = 1,2,3,4,5, etc...)
If you keep listing them out filling in x that should fill in the boxes.

The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there a

STatiana [176]

Answer:

24761 mosquitoes

5.4 days

Step-by-step explanation:

Let the equation that shows the population of the mosquitoes after x days,

$A=P(1+r)^x$

Where,

P = Initial population,

r = rate of increasing per day,

Here, A = 1000, when x = 0,

$1000=P(1+r)^0\implies P = 1000$

A = 1900 when x = 1,

$1900 = P(1+r)^1\implies 1900 = 1000(1+r)\implies 1.9 = 1 + r\implies r = 0.9$

Thus, the required function that represents the population after x days,

$A=1900(1+0.9)^x=1900(1.9)^x$

If x = 4,

The number of mosquito after 4 days,

$A=1900(1.9)^4 = 24760.99\approx 24761$

If A = 60,000,

$60000 = 1900(1.9)^x$

$\frac{600}{19}=1.9^x$

Taking log both sides,

$\log(\frac{600}{19})=x\log 1.9$

$\implies x = \frac{\log(\frac{600}{19})}{\log 1.9}=5.378\approx 5.4$

Thus, there will 60,000 mosquitoes after 5 days.

Can someone please help me with these problems. Thank you

P(3) = 1/6
P(odd) = 3/6 = 1/2 ........(odd = 1,3,5)
P(less than 5) = 4/6 = 2/3.....(less than 5: 1,2,3,4)
P(prime) = 3/6 = 1/2 ..........(prime: 2,3,5)
P(4 or 6) = 2/6 = 1/3
P(not 1) = 5/6 .....................(not 1: 2,3,4,5,6)

hope it helps
