SOMEONE THAT KNOWS PRE CALCULUS I NEED HELP ON THESE QUESTIONS
(Please don't leave stupid answers to take my points this is my third time asking for help on these and everyone just takes my points so please)

Answer:I have this same problem but if you’re asking for the independent and other questions here’s the answer. Independent variable is the radio since that’s the only change happening to the 10 other pots. Dependent variable is the height of the plant since that’s what Ramona wants to see change as the output. Control group is the 5 pots without the radio i’m pretty sure. The constants are the amount of seeds, pots, soil, and water.

Answer:

9( x-3) (x-1)

Step-by-step explanation:

(5x − 6)^2 − (4x − 3)^2

This is the difference of squares   a^2 - b^2 = ( a-b) (a+b)

(5x − 6)^2 − (4x − 3)^2   where a = 5x-6  and b = 4x-3

( 5x-6 - (4x-3))  ( 5x-6 +(4x-3)

Distribute

( 5x-6 -4x+3)  ( 5x-6 +4x-3)

Combine like terms

(x-3) ( 9x-9)

Factor out the 9

9( x-3) (x-1)

Answer:

Answer:

When the null hypothesis is rejected

The  conclusion is that there is enough evidence to support the claim of the researcher

When a type I error occurs

The consequences is that the conclusion that there is enough evidence to support the claim of the researcher is actually incorrect

When a type II error occurs  

 The consequences is  that the conclusion that there is enough evidence  to support the claim of the researcher is actually correct        

Step-by-step explanation:

From the question we are told that

The cost of electricity per month is [tex]\mu = \$104[/tex]

The null hypothesis is [tex]H_o : \mu = \$104[/tex]

The  alternative hypothesis is   [tex]H_o :  \mu  >   \$104[/tex]

Generally if the null hypothesis is rejected then the conclusion would be that there is enough evidence to support the claim of the researcher

Generally a Type I error is a an error that occurs when the null hypothesis is incorrectly rejected

So in the case of this question the consequence of making this type of error is that the conclusion that there is enough evidence to support the claim of the researcher is actually incorrect

 Generally a Type II  error is an error that occurs when the null hypothesis is incorrectly not rejected

So in the case of this question the consequence of making this type of  

error is that the conclusion that there is enough evidence to support the claim of the researcher is actually correct

Answer:

  2y -x = -6

Step-by-step explanation:

You can use the same x- and y-coefficients. You just have to change the constant on the right. Put the point values into the left expression to see the new constant.

  2y -x = 2(-1)-(4) = -6

The parallel line is ...

  2y -x = -6

4m+56.75=176.75

Solve the equation to find the cost of each mask.

Answer:

3 ÷ 1/3 = 9

Step-by-step explanation:

= 3 ÷ 1/3

= 3/3 (3/1) ÷ 1/3

= 9/3 × 3/1

= 9/1

= 9

Answer:

x= 13

Step-by-step explanation:

(X+2) 3 = (x-4) 5

distribute on both sides: 3x + 6 = 5x - 20

add 20 to both sides: 3x + 26 = 5x

subtract 3x from both sides: 26 = 2x

divide both sides by two: 13 = x

Answer:

x=13

Answer:

625

Step-by-step explanation:

625

Answer:

A regular polygon is a polygon that is equilateral and equiangular.

The only regular quadrilateral is the square.

We know that all the interior angles of a square are 90° each, so we are fine with that.

Now, for the exterior angles.

If we fix our position in the vertex, we can do from one side, to the same side, a full rotation of 360°.

Now, if we only do an external rotation, this means, from one side to other side, we will do a rotation of 360° minus the interior angle:

this is:

360° - 90° = 270°

Below is an image as a guide of this.

Answer: D

Step-by-step explanation:

(Using the formula in my attachment)

x^2 − 6x + 19

(x - 3)^2 = x^2 - 6x + 9

9 - e = 19

e = -10

(x - 3)^2 - e

(x - 3)^2 - - 10

(x - 3)^2 + 10

when x - 3 = 0, x = 3

Subsitute 3 into the equation

(3 - 3)^2 + 10

0 + 10

Minimum (3,10) in this case f(3) = 10

Step-by-step explanation:

The cardinality of a set a measure of the number of elements in a set.

A set is a group of objects that have a well defined relationship between them.

In the given set,  A={1,4,9}​

 The set of A has 3 elements which are 1, 4 and 9

So, the cardinality of this set is 3.

Answer:

The additional information that needed is m∠ABD = m∠CDB ⇒ C

Step-by-step explanation:

In the given figure

Triangles ADB and CBD are congruent by ASA under these conditions

Let us see the given to find the correct answer

∵ ∠ADB and ∠CBD have the same mark

∴ m∠ADB = m∠CBD ⇒ (1) given

∵ Side DB is a common side in the two triangles

∴ DB = BD ⇒ (2) given

∵ ∠ABD and ∠CDB are the angles at the end of BD

∴ m∠ABD must equal m∠CDB ⇒ (3) to prove the congruency using ASA

∴ The additional information that needed is m∠ABD = m∠CDB

Answer:

To prove that two triangles with three congruent, corresponding angles are congruent, you would need to have at least one set of corresponding sides that are also congruent. You could then use ASA or AAS congruence theorems or rigid transformations to prove congruence.

Answer:

y = (-3x/5) +1

Step-by-step explanation:

We know that the line passes through the point (-5 , 4)

AND

the slope is given to be -3/5

let's look at the slope a bit more

we know that the formula for slope of a line is Rise / Run

Which means that the rise of this line is -3 after spanning 5 units to the right

Hence, the line goes down 3 units after moving 5 units to the right

We know that to find the equation of a line through the point-slope equation, we need the slope as well as the y-intercept of the line

since we are already given the slope, we need to find the point where the line intersects the y-axis

Now, back to the given point the line passes through

this point has a x - coordinate of -5 and we know that after moving 5 units to the right, the line moves 3 units downwards

So, if the line moves 5 units to the right from the given point, it will reach the y- axis and we know that it's y-coordinate will decrease by 3

Hence, the y-intercept will be 3 units below the given y -coordinate

y - intercept = (4 - 3) =  1 = y-intercept

Now, using the slope-intercept formula to get the equation:

y =  (slope)*x + (y-intercept )

y = (-3/5)x + (1)

y = (-3x/5) + 1

Answer:

  -9.5

Step-by-step explanation:

The slope (m) is the ratio of the change in y to the change in x:

  m = (y2 -y1)/(x2 -x1)

  m = (10-(-9))/(-3-(-1)) = 19/-2

  m = -9.5

The slope of that line is -9.5.

The graph shows the line through those points, written in point-slope form.

Answer:

Step-by-step explanation:

= [tex](-\frac{\sqrt{3}}{2} - \frac{1}{2}i)^1^2[/tex]

= [tex](-\frac{\sqrt{3}}{2} - \frac{i}{2})^1^2[/tex]    

= [tex](\frac{\sqrt{3} -i}{2})^1^2[/tex]

apply the exponential rule:

    ([tex]-\sqrt{3}-i[/tex])¹²

=  --------------

         2¹²

note: ([tex]-\sqrt{3}-i[/tex])¹² = 4096

= 4096

  4096

= 1
