Consider this function for cell duplication where the cells duplicate every minute.
f(x) = 75(2)x
Determine what each parameter in the function represents.
A) The 75 is the initial number of cells, and the 2 indicates that the number of cells doubles every minute.
B) The 75 is the initial number of cells, and the 2 indicates that the number of cells increases by 2 every minute.
C) The 75 is the number of cells at 1 minute, and the 2 indicates that the number of cells doubles every minute.
D) The 75 is the number of cells at 1 minute, and the 2 indicates that the number of cells increases by 2 every minute.
Answer:
A) The 75 is the initial number of cells, and the 2 indicates that the number of cells doubles every minute.
Step-by-step explanation:
The function for cell duplication where the cells duplicate every minute, is given by [tex]f(x)=75(2)^x[/tex]
The initial number of cells occurs when x=0:
[tex]f(0)=75(2)^0[/tex]
Note that every non-zero number to the exponent of zero is 1.
[tex]\implies f(0)=75(1)=75[/tex]Therefore the initial number of cells is 75
The two is the multiplicative rate of change, therefore the 2 indicates that the number of cells doubles every minute.
suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Write an equation for the water level ,L ,after D days . In how any days will the water level be 26 feet
Equation: L= -0.5D+34.
The water level be 26 feet in 16 days.
Step-by-step explanation:
Let us consider the initial level (x=0) of the water is 34 feet. Then its coordinate point can be written as (0,34).
The water is receding at the rate 0.5 feet per day, which given us the information that 0.5 is the slope since it is the rate of change and it is decreasing so it is a negative slope.
⇒m= -0.5.
The line equation is y = mx+c. Let us rewrite as L= mD+c.
Where L is the level of water(y-axis) and D is the days(x-axis) and c is y-intercept.
⇒L= (-0.5)D+c.
To find y-intercept, substitute (0,34) (the known point from the graph) in the equation. Also, the point in y axis when x=0 is y-intercept.
34= (-0.5)(0)+c.
c=34.
∴L= (-0.5)D+34.
To find the days when the water achieves level as 26 feet:
26 = (-0.5)D+34.
26-34= (-0.5)D.
-8 = (-0.5)D.
D= [tex]\frac{-8}{-0.5}[/tex].
D= 16.

[tex]49x^2 + 84xy + 36y^2[/tex]
We have to find the binomial that is a factor to given expression
Let us find the factors of given equation
[tex]49x^2+84xy+36y^2\\\\\mathrm{Rewrite\:}49x^2+84xy+36y^2\mathrm{\:as\:}\left(7x\right)^2+2\cdot \:7x\cdot \:6y+\left(6y\right)^2\\\\\mathrm{Rewrite\:}49\mathrm{\:as\:}7^2\\\\7^2x^2+84xy+36y^2\\\\\mathrm{Rewrite\:}36\mathrm{\:as\:}6^2\\\\7^2x^2+84xy+6^2y^2\\\\\mathrm{Apply\:exponent\:rule}:\quad \:a^mb^m=\left(ab\right)^m\\\\7^2x^2=\left(7x\right)^2\\\\Therefore,\\\\\left(7x\right)^2+84xy+6^2y^2\\\\\mathrm{Apply\:exponent\:rule}:\quad \:a^mb^m=\left(ab\right)^m\\\\6^2y^2=\left(6y\right)^2\\\\[/tex]
[tex]Therefore\\\\\left(7x\right)^2+84xy+\left(6y\right)^2\\\\\mathrm{Rewrite\:}84xy\mathrm{\:as\:}2\cdot \:7x\cdot \:6y\\\\\left(7x\right)^2+2\cdot \:7x\cdot \:6y+\left(6y\right)^2\\\\\left(7x\right)^2+2\cdot \:7x\cdot \:6y+\left(6y\right)^2\\\\[/tex]
[tex]\mathrm{Apply\:Perfect\:Square\:Formula}:\quad \left(a+b\right)^2=a^2+2ab+b^2\\\\a=7x,\:b=6y\\\\Therefore,\\\\\left(7x\right)^2+2\cdot \:7x\cdot \:6y+\left(6y\right)^2 = \left(7x+6y\right)^2[/tex]
Thus we get,
[tex]49x^2 + 84xy + 36y^2 = (7x+6y)^2\\\\49x^2 + 84xy + 36y^2 = (7x+6y)(7x+6y)[/tex]
Thus the binomial which is a factor is 7x + 6y

enice brudley purchased 3,000 shares of GTI petroleum at $6.30 per share. The broker's commission was $19.95 for fewer than 1,000 shares or $0.02 per share for 1,000 or more. What was the cost of the stock? What was the total paid?
Answer:
Step-by-step explanation:
Cost of stock (without the broker's fee) : 3000 * 6.30 = 18,900
Cost of broker's fee: 3000 * 0.02 = $ 60
For a total cost of (18,900 + 60) = $18,960
Answer:
1. Cost of stock = $ 18,900
2. Total paid = $ 18,960
Step-by-step explanation:
1. Let's review the information provided to us to answer the questions correctly:
Number of GTI petroleum shares purchased by Enice = 3,000
Cost per share = $ 6.30
Broker's commission was $19.95 for fewer than 1,000 shares or $0.02 per share for 1,000 or more
2. What was the cost of the stock? What was the total paid?
Let's calculate the cost of the stock, this way:
Cost of stock = 3,000 * 6.30
Cost of stock = $ 18,900
Cost of brokers' commission = 3,000 * 0.02
Cost of brokers' commission = $ 60
Total paid = Cost of stock + Cost of broker's commission
Total paid = 18,900 + 60
Total paid = $ 18,960

A laptop is $891.99 before sales tax. If the sales tax rate is 7.5%, find the total of the laptop WITH the sales tax included.
Answer:
958.88925
Step-by-step explanation:
the percentage of tax is that much of the total price. if there is 50% sales tax (unrealistic) and the item costs 100 dollars without any tax, then the tax would be 50 dollars. To find this, turn the percent into a decimal (move the decimal place to the left twice) and multiply that by the price. To do this with this problem, use this strategy. 891.99 times 0.75= 66.89925+891.99=958.88925. might need to be simplified tho, hope this helps

over three successive Collins build 1/3, 1/5 and 1/4 of the brickwork of his new garage. What fraction must he complete on the fourth and final day
Answer:
1 - 1/3 - 1/4 - 1/5
Step-by-step explanation:
Let's take it one step at a time.
Day 1 he completes 1/3 of the garage, so you subtract 1/3 from 1 which means he left 2/3
Day 2 he completed 1/4 more, so you again subtract, this time though 2/3 - 1/4, or in other words 1 - 1/3 - 1/4
So you do this one more time. 1 - 1/3 - 1/4 - 1/5

I need some help answering this math question
Answer:
3168 feet / minute
Step-by-step explanation:
Plant B is 6 2/3 inches tall. and C is 4 4/15 inches tall. Complete the sentences and show your reasoning
Plant C is (answer) times as tall as plant B
Plant C is (answer) inches (answer) taller or shorter than plant B
Answer:
Step-by-step explanation:
Plant B is taller than Plant C. We need to determine by how much. To do this, we divide 6 2/3 inches by 4 4/15 inches. The LCD is 15, and so we have:
6 10/15 100/15
----------- or ------------- = 100/64 = 20/16 = 5/4
4 4/15 64/15
Plant B is 1 and 1/4 times taller than Plant C. This can be restated as Plant C is four fifths as tall as Plant B.
Plant C is shorter than Plant B, as we saw earlier. The difference is found through subtraction: 100/15 - 64/15 = 36/15 inches = 12/5 inches shorter, or 2 2/5 inches shorter
Plant C is approximately 12 4/5 times as tall as Plant B. Plant C is approximately 2 2/5 inches shorter than Plant B.
Explanation:To find out how many times larger Plant C is compared to Plant B, we need to divide the height of Plant C by the height of Plant B. In this case, Plant C is 4 4/15 inches tall and Plant B is 6 2/3 inches tall.
So, the calculation would look like this:
4 4/15 ÷ 6 2/3
To divide fractions, we need to convert the mixed numbers into improper fractions. So, Plant C is 64/15 inches tall and Plant B is 20/3 inches tall.
Now we can divide the fractions:
64/15 ÷ 20/3 = (64/15) x (3/20)
Cancel out common factors:
64/5 ÷ 1/1 = 64/5 = 12 4/5
Plant C is approximately 12 4/5 times as tall as Plant B.
To find out whether Plant C is taller or shorter than Plant B, we need to subtract their heights. Plant C is 4 4/15 inches tall and Plant B is 6 2/3 inches tall.
So, the calculation would look like this:
4 4/15 - 6 2/3
Again, we need to convert the mixed numbers into improper fractions:
Plant C is 64/15 inches tall and Plant B is 20/3 inches tall.
Now we can subtract the fractions:
64/15 - 20/3 = (64/15) - (20/3
To subtract fractions, we need to have the same denominator. So, we need to find a common denominator for 15 and 3, which is 15.
64/15 - 100/15 = -36/15 = -2 6/15 = -2 2/5
Plant C is approximately 2 2/5 inches shorter than Plant B.
