Answer:
7 days
Step-by-step explanation:
(a) Filling in the given information will result in two equations in the two unknowns. Dividing one by the other will tell you the value of b.
n=2
1.8 = A₀·b²
n=3
2.4 = A₀·b³
Dividing the second equation by the first gives ...
2.4/1.8 = (A₀·b³)/(A₀·b²) = b
4/3 = b
__
(b) Substituting this into the first equation, we can find A₀.
1.8 = A₀·(4/3)²
1.8(9/16) = A₀ = 1.0125
A₀ is the value of A when n=0. It is the area of the patch at the beginning of observation, before any days passed.
__
(c) The area will be 7 cm when ...
1.0125·(4/3)^n = 7
(4/3)^n = 7/1.0125 . . . . . . . . . . . . divide by A₀
n·log(4/3) = log(7/1.0125) . . . . . . take logarithms
n = log(7/1.0125)/log(4/3) ≈ 6.72092
It will take about 7 days for the area of the patch to exceed 7 cm.

Answer:
y=4x+3
Step-by-step explanation:
Slope of the line is 4
So the equation of the parallel line is y=4x+b
To find b we use the points
-5=(4)(-2)+b
Solve
-5=-8+b
3=b
Then submit the values
y=4x+3

x2 + 7y if x = -5 and y = -8
Answer:
x2 + 7y = -64 (if x = -5 and y = -8)
Step-by-step explanation:
x2 + 7y
(-5 × 2) + (7 × -8)
-10 + -54 which is the same as -10 - 54
-64
The value of expression x² + 7y at x = - 5 and y = - 8 is, - 31.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ x² + 7y
And, x = - 5 and y = - 8
Now, Substitute the value of x and y in the expression, we get;
⇒ x² + 7y
⇒ (-5)² + 7×- 8
⇒ 25 - 56
⇒ - 31
Thus, The value of expression is, - 31.

How many milliliters are 1/5 liter
1/5 liters = 200 milliliters
Multiply polynomials
Answer -2x^4 - 2x^3 + 22x^2 - 30x + 12
Here's your solution
=> (2x^2 - 4x + 2) - (x^2 + 3x - 6)
=> (2x^2 - 4x + 2) -x^2 - 3x + 6
=> firstly multiple whole with -x^2
=> -x^2(2x^2 - 4x + 2) = -2x^4 + 4x^3 - 2x^2
=> now with -3x
=> -3x(2x^2 - 4x + 2) = -6x^3 +12x^2 -6x
=> with 6
=> 6(2x^2 - 4x + 2) = 12x^2 - 24x + 12
=> now add all terms
=> -2x^4 - 2x^3 + 22x^2 - 30x + 12
hope it helps and your day will be full of happiness ^_^

Between 12:00 PM and 1:00 PM, cars arrive at a local bank's drive-thru at the rate of cars per hour ( car per minute). The formula below from probability can be used to determine the probability that a car will arrive within t minutes of 12:00 PM. Use this information to answer the questions given below in parts (a)(e).
Complete question :
Between 12:00 PM and 1:00 PM, cars arrive at Citibank’s drive-thru at the rate of 6 cars per hour (0.1 car per minute). The following formula from statistics can be used to determine the probability that a car will arrive within t minutes of 12:00 PM. F(t)=1−e^−0.1t
Determine how many minutes are needed for the probability to reach 80%.
Answer:
16.09 minutes
Step-by-step explanation:
Given the function :
F(t)=1−e^−0.1t
To attain 80% probability ; 80% = 0.8
0.8 = 1 - e^-0.1t
0.8 - 1 = - e^-0.1t
-0.2 = - e^-0.1t
Take the In of both sides
In(0.2) = In( e^-0.1t)
−1.609437 = - 0.1t
Divide both sides by - 0.1
−1.609437 / -0.1 = - 0.1t / 0.1
16.09 = t
Hence, the time it'll take will be 16.09 minutes
Answer:
80/100=0.80
.8=1-e^-0.3t
.8+1=-e^-0.3t
1.8=-e^-.3t
t=5.36

Mariela bought gas for her car. Gas costs $2.12 per gallon, and
Mariela bought 23.5 gallons. How much did Mariela spend on gas?
Round to the nearest cent.

Let X and Y be the following sets: X = {0, 12, 23} Y = {3, 12, 15) Which of the following is the set X/Y?
Answer:
set X/Y = {0,23}
Step-by-step explanation:
We are given the sets;
X = {0, 12, 23}
Y = {3, 12, 15}
Now, we want to find the set X/Y.
The set X/Y means the set that has numbers which are only in set X but not in set Y.
The numbers from inspection of both sets are 0 and 23.
Thus;
set X/Y = {0,23}
A bag contains 8 red M&Ms, 13 blue M&Ms, 4 brown M&Ms, and 8 green M&Ms. An M&M is picked at random from the bag. What is the probability of picking: A Red M&M:
Given:
Number of red M&Ms = 8
Number of blue M&Ms = 13
Number of brown M&Ms = 4
Number of green M&Ms = 8
An M&M is picked at random from the bag.
To find:
The probability of picking a red M&M.
Solution:
We have,
Number of red M&Ms = 8
Total number of M&Ms [tex]= 8+13+4+8[/tex]
[tex]=33[/tex]
So, probability of picking a red M&M is:
[tex]\text{Probability}=\dfrac{\text{Number of red M&Ms}}{\text{Total number of M&Ms}}[/tex]
[tex]\text{Probability}=\dfrac{8}{33}[/tex]
Therefore, the probability of picking a red M&M is [tex]\dfrac{8}{33}[/tex].
