The formula for the density of a bacteria population is \dfrac NA A N ​ start fraction, N, divided by, A, end fraction where there's an average of NNN bacteria in an area size AAA. Guang and Orion are doing an experiment in school for which they need to measure the density of a bacteria population after a certain solution has been introduced. Guang reports a density of 450045004500 bacteria per square centimeter and Orion reports a density of 505050 bacteria per square millimeter. Which one reports a higher density? Choose 1 answer:

Answers

Answer 1

Answer:

Guang reports a higher density of 4.5 × 10⁷ bacteria/m²

Step-by-step explanation:

Since Guang reports a density of 4500 bacteria per square centimeter and Orion reports a density of 50 bacteria per square millimeter, we convert both densities into bacteria per square meter to compare their values.

So, for Guang 4500 bacteria/cm² = 4500 bacteria/cm² × 10⁴ cm²/1 m² = 4500 × 10⁴ bacteria/m² = 4.5 × 10⁷ bacteria/m²

For Orion 50 bacteria/cm² = 50 bacteria/cm² × 10⁴ cm²/1 m² = 50 × 10⁴ bacteria/m² = 5 × 10⁵ bacteria/m²

Since 4.5 × 10⁷ bacteria/m² > 5 × 10⁵ bacteria/m², Guang reports a higher density of 4.5 × 10⁷ bacteria/m²

Answer 2

Answer:

B.) orion reports a higher desity than guang

Step-by-step explanation:

We found that Guang's reported density is 45 bacteria/ millimeter^2, while orion's reported density is 50 bacteria/ millimeter^2.

Hi there! :)

C. has both jump and infinite discontinuity.

Evaluate both piecewise functions at x = 1;

1 / (x + 1) = 1 / ((1) + 1) = 1/2

2x - 1 = 2(1) - 1 = 1

As the piecewise functions contain different y-values when evaluated at

x = 1,  there is a jump discontinuity at x = 1.

However, the first function also contains a vertical asymptote or infinite discontinuity where it is undefined, or at x = -1. (1 / 0 = undefined). This means that the function also contains an infinite discontinuity.

Therefore, the correct choice is:

C. has both jump and infinite discontinuity.

Given the function f(x) = −2x2 + 3x + 10, find f(1) and f(3). Choose the statement that is true concerning these two values.

Answers

Answer:

The value of f(1) is greater than value of f(3)

Step-by-step explanation:

We substitute..x = 1..into the given equation....where we say...

; -2(1)^2 + 3(1) + 10 = 11

Then we substitute..x = 3..into the given equation

;-2(3)^2 + 3(3) + 10

;-2(9) + 9 + 10 = 1

If f(1) = 11 and f(3) = 1...then the value of f(1) is greater than the value of f(3)

Step-by-step explanation:

The given function is f(x) = -2x² + 3x + 10. We are asked to find f(1) and f(3).To find f(1), we substitute 1 in the place of x in the given function and evaluate it.

That is,f(1) = -2(1)² + 3(1) + 10= -2 + 3 + 10= 11To find f(3), we substitute 3 in the place of x in the given function and evaluate it.
That is,f(3) = -2(3)² + 3(3) + 10= -18 + 9 + 10= 1We see that f(1) is larger than f(3).


Hence, the correct answer is "The value of f(1) is larger than the value of f(3)."

The given equation can be rearranged to equate both side of the equation and thus we can get equivalent on both side as 6 (2y-3) = 6 (2y-3). Therefore, y can have any values from 0.

What are algebraic equations?

Algebraic equations are expression used to represent the relation between two values by some letters or alphabets whose values are not specified in the equation.

In general, the letters x and y are used in the algebraic equations. They can linear or non-linear equation. By rearranging this equations we can determine the values of x and y.

Given the expression 12 y - 18 = 6 (2y - 3). From the left hand side, divide the part 12 y - 18 by 6. Thus we obtain the expression equivalent to the right hand side as 6 (2y - 3).

Therefore, 6 (2y - 3) = 6 (2y - 3). Which means both sides are equal and have equal value of y. means y can have any values from zero since all the terms including y is zero both side.

Thus, giving any value to y will always remains the same equation.

Sue used to have a square garage with 286 ft squared of floor space. He recently built an addition to it. The garage is still a​ square, but now it has​ 50% more floor space. What was the length of one side of the garage​ originally? What is the length of one side of the garage​ now? What was the percent increase in the length of one​ side?

Answers

Answer:

New Length = 20.71 feet

Original Length = 16.91 feet

22.47%

Step-by-step explanation:

Original area of the square garage = 286 ft squared

Addition of 50% more space

New area of the garage = 286 + .50(286)

= 286 + 143

= 429 square feet

What was the length of one side of the garage​ originally?

Original area of the square garage = 286 ft squared

Area of a square = length^2

286 = length^2

Find the square root of both sides

√286 = √length^2

Original Length = 16.91 feet

What is the length of one side of the garage​ now?

New area of the garage = 429 square feet

Area of a square = length^2

429 = length^2

Find the square root of both sides

√429 = √length^2

New Length = 20.71 feet

What was the percent increase in the length of one​ side?

(New length - old length) / old length × 100

= (20.71 feet - 16.91 feet) / 16.91 feet × 100

= 3.8 feet / 16.91 feet × 100

= 0.2247 × 100

= 22.47%

Write an equation in slope-intercept form of the line that passes through (6,-1) and (3,-7). Please help!

Answers

Answer:

y = 2x – 13

Step-by-step explanation:

Use Slope formula to get the slope

(y2-y1) / (x2-x1)

(-7--1) / (3-6)

(-6)/(-3)

2

Then plug-in the value of slope and any one coordinate in Point-Slope formula:

y- y1= m(x-x1)

y - -1 = 2( x - 6)

y + 1 = 2x - 12

y = 2x - 13

The equation of the line in the slope-intercept form will be y = 2x – 13.

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = (-7-(-1)) / (3-6)

Slope = (-6)/(-3)

Slope = 2

Then plug in the value of slope and any one coordinate in the Point-Slope formula:

y- y₁= m(x-x₁)

y - (-1) = 2( x - 6)

y + 1 = 2x - 12

y = 2x - 13

Therefore, the equation of the line in the slope-intercept form will be y = 2x – 13.
