The values you should plot to show a linear relationship is;

C. "Day" on the x-axis and "Log(bacteria)" on the y-axis

The table for the relationship between days and number of bacteria is;

Days       Bacteria          log bacteria

0               2                      0.301

1                5                      0.699

2               8                      0.903

3                15                    1.176

4                33                   1.516

5               65                    1.813

We see from the table that bacteria is showing exponential growth  

Thus, if log of bacteria is plotted against day, it will show a linear relationship.

Therefore, the graph will be plotted as Day on the x-axis and Log(bacteria) on the y-axis

Step-by-step explanation:

Given Equation :-

On comparing :-

Slope of perpendicular line :-

Using Point slope form :-

Answer:

The equation for this line in slope-intercept form (y = mx + b) is y = [tex]\frac{5}{4}[/tex]x + 2, because the rise (5) over the run (4) is the slope aka 'm', and the line touches the y-axis at the point (0,2) In this ordered pair the y-value is 2, so the y-intercept, or 'b', is equal to 2.

Answer: absolute values

Step-by-step explanation:

Answer:

hi! the slope formula is y2-y1 / x2-x1 ! so (-6,0) (2,-2)

your x1 is -6 and y1 is 0 and x2 is 2 and y2 is -2!

using the formula, -2-0/2--6 is 4

so your slope is 4!

the y intercept is solved by

the slope intercept formula y= mx+b

I hope you've memorized both formulas!

b is your y intercept so let's set the equation up!

pick a point it can be either point we'll do (-6,0)!

now y=mx + b

m is your slope and y is the y coordinate of the point (-6,0) that we chose!

b is what we will solve

so! 0=4(-6)+b

0= -24 + b

now it's basic algebra!

24= b

I hope this helps!

In conclusion, slope is 4 and y intercept is 24

memorize slope formula and slope intercept formula and you can do this!

Answer:

Your answer is 38 degrees.

Step-by-step explanation:

The question was solved through the properties of a circle. The angle subtended at the center is double the angle subtended at the circumference.

Hope I helped, happy schooling!!

The measure of <C is 38°. The answer is the first option 38°

From the question, we are to determine the measure of <C.

In the diagram, <C is an angle on a part of the circumference.

From the given information, the angle subtended by arc AB at the center of the circle is 76°

From one of the circle theorems we have that

The angle subtended by an arc of a circle at its center is twice the angle it subtends anywhere on the circle's circumference

Therefore,

2 × <C = 78°

<C = 76° ÷ 2

<C = 38°

Hence, the measure of <C is 38°. The answer is the first option 38°

Answer:

x=[tex]-\frac{113}{3}[/tex]

Step-by-step explanation:

First, we need to solve the angle inside the triangle. That would be 55+40+angle measure=180

angle measure=85°

Now that we know that, we can solve for x by setting 85-3x-18 equal to 180° because these two values form a linear pair which is 180°.

Let's use some simple algebra to solve for x:

85-3x-18=180

67-3x=180

-3x=113

x=[tex]-\frac{113}{3}[/tex] or about -37.67

Answer:

the ordered triple of these equations will be:

(x, y, z) = (6, 1, 5)

Step-by-step explanation:

Given the equations

[tex]x + y + z = 12[/tex]

[tex]y=1[/tex]

[tex]x - y - z = 0[/tex]

As

[tex]y=1[/tex]

We can get the value of x by adding the first and third equation

so

[tex]x + y + z = 12[/tex]

[tex]x-y-z=0[/tex]

so the equations become

[tex]x+x+y-y+z-z=12+0[/tex]

[tex]2x = 12[/tex]

[tex]x = 6[/tex]

Putting x = 6 and y=1 in the first equation [tex]x+y+z=12[/tex]

[tex]6 + 1+ z = 12[/tex]

[tex]7 + z = 12\\z = 12 -7[/tex]

[tex]z = 5[/tex]

Therefore, the ordered triple of these equations will be:

(x, y, z) = (6, 1, 5)

Answer:

The equation in the slope-intercept form will be:

[tex]y=6x-3[/tex]

Step-by-step explanation:

Given

As we know that the equation of a line in point-slope form is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 6 and point = (1, 3)

[tex]y-3=6\left(x-1\right)[/tex]

Writing the equation in slope-intercept form

[tex]y=mx+b[/tex]

where m is the slope, and b is the y-intercept

so the equation of the line in slope-intercept form becomes

[tex]y-3=6\left(x-1\right)[/tex]

add 3 to both sides

[tex]y-3+3=6\left(x-1\right)+3[/tex]

[tex]y=6x-3[/tex]

Therefore, the equation in the slope-intercept form will be:

[tex]y=6x-3[/tex]

Answer:

(A) The pizzeria needs to sell 90 pizzas to receive the bonus.

(B) It would be a 12% decrease then the original amount of pizzas sold which is 75.

Step-by-step explanation:

(A)- You convert 20% into a decimal which is 0.20 then multiply it to 75 to find out how many more pizzas need to be sold for them to receive the bonus. In this case it was 15. Then you add it to the 75 and you get 90. So the pizzeria needs to sell 90 pizzas for them to receive their bonus.

(B)- First you see if it was an increase or decrease. In this case it was a decrease because it dropped from 75 to 66. Now you calculate by how much it had dropped. Here it dropped by t9. Now to find the percent on how much it dropped you divide 9 by 75 and you get 0.12. Then you multiply by 100 to get your percentage with is 12%. So the number of pizzas sold today would show as a 12% decrease.
