HELP! How do I complete this table?

Answer:

x1 = 2.86

x2 = -0.53

Step-by-step explanation:

[tex]a=6, b=-4, c=-9[/tex]

[tex]x=\frac{-(-14)+-\sqrt{(-14)^{2}-4(6)(-9) } }{2(6)}[/tex]

[tex]x=\frac{14+-\sqrt{412} }{6}[/tex]

[tex]x=\frac{14+-20.3}{12}[/tex]

[tex]x_{1} =\frac{14+20.3}{12} =2.86[/tex]

[tex]x_{2} =\frac{14-20.3}{12} =-0.525[/tex]

Hope this helps

Answer:

66

Step-by-step explanation:

The diameter of the circle is 21. The formula for circumference is pie*radius*2. We don't have the radius but the diameter is just double the radius so just don't multiply by 2. 21 x 22 = 462. 46s divided by 7 is 66. Enjoy your answer :D

Answer:

the first one is _2

second one is 3

to get the slope of any straight line we only need two points off of it, let's use the ones in the picture below.

[tex](\stackrel{x_1}{-1}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-8}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-8}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{(-1)}}}\implies \cfrac{-10}{4+1}\implies \cfrac{-10}{5}\implies -2[/tex]

Answer:

Step-by-step explanation:

Given,

Edges of a box = 12 in. , 15 in. , 6 in.

So,

Lateral Surface Area (LSA) of the box

= 2 (l + b) h

= [2 (12 + 15) × 6 ] [tex]in^{2}[/tex]

= [2 × 27 × 6] [tex]in^{2}[/tex]

= 324[tex]in^{2}[/tex]

And,

Base area of the box

= l × b

= (12 × 15) [tex]in^{2}[/tex]

=  180 [tex]in^{2}[/tex]

Therefore,

Total area painted by Agnes leaving the top of the box

= LSA of the box + Base area of the box

= 324[tex]in^{2}[/tex] + 180 [tex]in^{2}[/tex]

= 504[tex]in^{2}[/tex]

Hence,

The total area painted is 504[tex]in^{2}[/tex] (Ans)

Answer:

(i) The factors of the given polynomial is (x – 22) and (x + 10)

(ii) If she purchase 5kg papaya then she pays 110

Step-by-step explanation:

Now,

x² – 12x – 220 = 0

Splitting the middle term

x² – 22x + 10x – 220 = 0

x(x – 22) + 10(x – 22) = 0

(x – 22) + (x + 10) = 0

x – 22 = 0 or x + 10= 0

x = 22 or x = -10

Here, (-10) is the negative value hence it is not possible

So, The value of x is 22

The factors of the given polynomial is (x – 22) and (x + 10)

if she purchase 5kg papaya then,

we know the price of 1 kg papaya i.e., 22 per kg

So,

5 × 22 = 110

Thus, if she purchase 5kg papaya then she pays 110

Answer:

225%

Step-by-step explanation:

54 = 24 of x

54 = .24x

Divide both side by the same number

54/.24 = .24x/.24

= 225%

Step-by-step explanation:

Hey there!

The given equation is: - 2x + 3y = 6

Part A:

The slope intercept form equation is: y= mx+c.

So, make the equation in y= mx+c form.

- 2x + 3y = 6

Shift -2x right side;

3y = 6+2x

Divide both sides by 3.

y = (6+2x)/3

y = (2/3)x +2

Therefore, the required equation in slope intercept form is: y = (2/3)x +2.

Part B:

When the equation is in y= mx+c form "c" represents the y-intercept.

So, y-intercept is 2.

Part C:

From the equation y = (2/3)x +2,

The slope (m) = 2/3.

Answer: Here is the answer.

Step-by-step explanation: we have to multiply each of the terms with the other terms.

=(-p²+4p-3)(p²+2)

=-p²*p²+ ( -p²*2) + 4p*p² + 4p*2 - 3*p²+ ( -3*2)

= -p³ -2p²+4p³+8p-3p²-6

=3p³-5p²+8p-6  (I grouped the like terms and added them)

therefore, 3p³-5p²+8p-6 is the polynomial in the standard form.

Answer:

the two numbers are 5 and 17

Step-by-step explanation:

4y - 3 = x

x - 2y = 7

to find y:

x - 2y = 7

(4y - 3) - 2y = 7

2y - 3 = 7

2y = 7 + 3

2y = 10

y = 10/2

y = 5

to find x :

4y - 3 = x

4 ( 5 ) - 3 = x

20 - 3 = x

17 = x

Step-by-step explanation:

Solution,

In the given cuboid, area of total surface (A)=280 cm²

Breadth ( b ) = 5 cm

Height ( h ) = 6 cm

Total surface area of cuboid = 2 ( lb + bh + lh )

or , Area = 2 ( lb + bh + lh )

or , 280 = 2 ( l × 5 + 5 × 6 + l × 6 )

or , 280 = 2 ( 11 l + 30 )

or , 2 ( 11 l + 30 ) = 280

or , 11 l + 30 = 280 ÷ 2

or , 11 l + 30 = 140

or , 11 l = 140 - 30

or , 11 l = 110

or , l = 110 ÷ 11

l = 10

Thus, the length is 10 cm...

Answer:

$1,824

Step-by-step explanation:

Games Dave wants to buy: 5

Cost of each game: $50

Cost of 5 games = $50 x 5

= $250

Funko pops Dave wants to buy: 10

Cost of each funko pop: $30

Cost of 10 funko pops = $30 x 10

= $300

Toys Dave wants to buy: 6

Cost of each toy: $40

Cost of 6 toys = $40 x 6

= $240

Sum of all Dave's things = ($250 + $300 + $240)

= $790

Money Dave has = $2,614

Money left with him = ($2,614 - $790)

= $1,824

Hence, $1,824 are left with Dave after buying 5 games, 10 Funko pops and 6 toys.

Pls correct me, if I am wrong :)

Have a great day!

Thanks!

Answer:

x has to be greater than 0

Step-by-step explanation:

It basically shows you that based on the inequality sign.

Answer:

x solved is 0 < x

and graphing it on the number line

-1  0  1

    O->

Step-by-step explanation:

So, solving for x is easy you divide the 2 from 2x onto the other side and 0/2 is 0 meaning 0 < x, the < stays the same as you divided with a positive and it would start at 0 and the line would go to the right as 0 is less than x. if you have to it would be a open circle with a dotted line if deltamath makes you do that too.

The area of a triangle is base times height divided by two

Answer:

Last month it sold 338 cakes.

Step-by-step explanation:

Let total cakes this month,last month and last 3 months be x,y and z respectively,

x = y + 10...

x = 3z

z = 116

Now, we have to find y,

x = y + 10

or, 3z = y + 10

or, 3•116 = y + 10

or, 348 = y + 10

or, y = 348 - 10

so, y = 338

Step-by-step explanation:

Don't quote me on that but I'm pretty sure

Answer:

If this point is 0, -5, one of the points of symmetry would be a simple reverse on the y axis. It would be 0, 5.

If we are talking respect to the x axis in general, another reverse point or quadrant would be -5, 0.
