Answer:

The zeroes of the function are: 3 and 4

Step-by-step explanation:

Zeroes of a function are the values on which the function produces zero output. To find the zeroes of a function, the function is put equal zero and the values of the variable are found using the equation. The values of x are the zeroes of the function.

Given function is:

[tex]f(x) = (x-3)(2x-8)[/tex]

Putting the function equal to zero

[tex]f(x) = 0\\(x -3)(2x -8) = 0\\x-3 = 0\\x = 3\\2x-8 = 0\\2x = 8\\\frac{2x}{2} = \frac{8}{2}\\x = 4[/tex]

We get two values for x, x=3 and x=4

Hence,

The zeroes of the function are: 3 and 4

Answer:

C. y = 945x + 2,835

Step-by-step explanation:

Each pay period 945 dollars is deposited so that's the slope, which x stands for each pay period. She already started with 2,835 in her savings account so that is the y-intercept.

Slope: 945x

Y- intercept: 2,835

Therefore,

equation: y = 945x + 2,835

Zeros :

[tex]x = - 2[/tex]

[tex]x = 4[/tex]

[tex]x = 7[/tex]

Thus ;

[tex]x + 2 = 0[/tex]

[tex]x - 4 = 0[/tex]

[tex]x - 7 = 0[/tex]

Multiply above equations :

[tex](x + 2)(x - 4)(x - 7) = 0[/tex]

Expand

[tex]( {x}^{2} - 2x - 8)(x - 7) = 0[/tex]

[tex] {x}^{3} - 7 {x}^{2} - 2 {x}^{2} + 14x - 8x + 56 = 0 \\ [/tex]

[tex] {x}^{3} - 9 {x}^{2} + 6x + 56 = 0[/tex]

[tex]y = f(x) = {x}^{3} - 9 {x}^{2} + 6x + 56 \\ [/tex]

if you set a table with 4/20=?/100 then cross multiply and divide giving you 20

Answer:

20 6th Graders choose candy

Step-by-step explanation:

4/20 equals 0.2

so 100 time .2 equals 20

also 4/20 simplified is 1/5

you could mutiply (100 times 1/5 = 20)

Answer:

2.3 mL

Step-by-step explanation:

This is called finding the volume by displacement. By subtracting the final volume and the initial volume you can determine how much the volume changed when the object was added. That change in voulme represents the volume of the object, so in this case:\

14.5-12.2 = 2.3 mL

The change in the volume of the object is, 2.3 mL.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

We have to given that;

An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL .

Here, An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL .

Hence, The change in the volume of the object is,

⇒ 14.5 - 12.2 mL

⇒ 2.3 mL

1. More time for studying

2. Possibly change your study habits

3. Make sure that you are learning with the technique that works best for you

Step-by-step explanation:

1. Allow yourself more time to study. If this is a specific subject that you feel that you are struggling in, allow yourself more time in a day to study your notes and prep for classwork, tests, etc. in comparison to your other classes.

2. If you feel that your current studying method(s) is working for you, great! If not, there are so many other methods that may work better for you. There's tons of videos on the internet regarding ways to study, there's internet articles explaining ways, and so many other resources! You may learn new ways to take notes, find the perfect balance of studying and taking breaks, and possibly even new memorization techniques! Just find out what works best for you!

3. Ask yourself what kind of learning method you prefer. If you prefer working in groups, maybe meet up with some friends for a group study session in which you guys can discuss ideas and questions. If you can't meet in person, try a zoom call! If you prefer learning with visual methods, maybe find some videos on the topic with visuals to demonstrate! Try to study with your preferred method of learning as often as you can!

If you have any other questions, just let me know! I'm happy to help and hope these tips help as well! :)

Answer:

x = 4.52984

Step-by-step explanation:

Since the triangle has a right angle you need to use the the trigonometric function cos (theta which is the angle given that isn't 90°) = adjacent / hypotenuse (adjacent is the side close to the angle you're using which is 22° and the hypotenuse is the longest side of the triangle that is in the away from the right angle)

From there you plug in the numbers which now become cos (22°) = 4.2 / x

Then you isolate the x by multiplying it to both sides so it's on the left and divide both sides by cos (22°) which will end you up x = 4.2 / cos (22°)

Then you just divide and you 4.52984

Step-by-step explanation:

A graph represents a function when no vertical line will intersect the graph in more than one point.

Step-by-step explanation:

x + 1 + 2x + 2 + 12x - 18 = 180 (sum angles in triangle)

15x - 15 = 180

15x = 195

x = 13deg

Topic: Angles

If you like to venture further, do check out my insta (learntionary) where I constantly post math tips! Thanks!

Step-by-step explanation:

(x+1)°+(2x+2)°+(12x-18)°=180°

15x+3°-18°=180°

15x+15°=180°

15x=180°-15°

x=165°/15°

Answer:

D) m<1 = 50 m<7 = 130

Step-by-step explanation:

Lets set up the equation!

We know m<4 is 4x-30 and the m<5 is 2x + 50 due to alternate interior angles they are congruent so we can forge an equation, all we do is set them equal to each other!

4x-30 = 2x+50

Add 30 to both sides

4x = 2x +80

Subtract 2x from both sides.

2x = 80

Divide both sides by 2

x = 40

Now that we know x we can just plug it into the expression of m<4 to find m<1

4x-30

4(40)-30

80 - 30

50

m<4 = 50

Because m<1 and m<4 are vertical angles they are congruent!

m<1 = 50

We also know m<4 and m<5 are congruent so m<5 = 50 as well.

Because <7 is supplementary to <5 we know that the sum of both angles amount to 180.

x represents m<7

50 + x = 180

Now we solve by subtraction 50 from both sides

x = 130

m<7 = 130
