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.

Answer: [tex]5y - x = -25[/tex]

Step-by-step explanation:

The formula for calculating equation of line when a point and a slope is gives is :

[tex]y - y_{1} = m ( x - x_{1})[/tex]

[tex]x_{1} = 10[/tex]

[tex]y_{1} = -3[/tex]

[tex]m = \frac{1}{5}[/tex]

substituting into the formula , we have

[tex]y - (-3) = \frac{1}{5}(x - 10 )[/tex]

[tex]y + 3 = \frac{1}{5}(x - 10 )[/tex]

multiply through by 5 ,

[tex]5 (y+ 3 ) = x - 10[/tex]

[tex]5y + 15 = x - 10[/tex]

in standard from , we have

[tex]5y - x = -10 - 15[/tex]

[tex]5y - x = -25[/tex]

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

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.

7x + 6y is a binomial that is a factor of given equation

Solution:

A binomial is a mathematical expression which has only two terms

Given expression is:

[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

Step-by-step explanation:

Use the red dots as two points in the line.

Slope = change in y over the change in x.

point 1: (-5,4)

Point 2: (5,-2)

Slope = (-2 - 4) / ( 5 - -5)

Slope = -2/10

Slope = -1/5

Answer:

3/-5

Step-by-step explanation:

The formula for the slope of a line is rise over run, rise/run

So from any given two points, you can calculate this.

rise is 3

run is 5, but it would be negative 5 because the slope of the line is negative.

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

Can you handle this or do you need help with fraction subtraction.

Answer:

A rewards customer earns 2 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.

Step-by-step explanation:

Just took the test y'all Trust me the answer is A.

The statement *(A) "A rewards' customer earns 2 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same" is correct,

A line graph is a graph made up of segments of straight lines that connect the depicted data points.

We have a graph represents the customer pays for 106 ounces and 12 ounces of much a rewards' customer pays based on the number of yogurt.

Based on the graph, we can say a rewards' customer earns 2 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.

Thus, the statement *(A) "A rewards' customer earns 2 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same" is correct,

Answer: a 3,-2

Step-by-step explanation:

When a point is rotated, it must be rotated around a center.

The coordinate of the image of (-2,-3) is (3,-2)

The point is given as:

[tex](x,y) = (-2,-3)[/tex]

The rule of 90 degrees counterclockwise rotation is:

[tex](x,y) \to (-y,x)[/tex]

So, we have:
