Answer:

See explanation

Step-by-step explanation:

Let the given equation be:

[tex]5 {x}^{2} - 400 = 0[/tex]

This implies that:

[tex]5 {x}^{2} = 400[/tex]

Divide through by 5 to get;

[tex] {x}^{2} = 80[/tex]

Take square root to obtain:

[tex]x = \pm \sqrt{80} [/tex]

This implies that

[tex]x = \pm4 \sqrt{5} [/tex]

[tex]x = - 4 \sqrt{5} \: or \: x = 4 \sqrt{5} [/tex]

Answer:

None of the above

Step-by-step explanation:

Answer:

$36

Step-by-step explanation:

The amount spent on cloths is 1/3

The amount earned from washing the car is $5

Amount at the end of the week is $29

Let the amount earned that week be x

Then amount spent on cloths = 1/3x

so the equation is

x- 1/3 x+$5=$29

2/3 x=29-5

2/3 x= 24

x=(24*3)/2= $36

Answer:

x = [tex]\frac{3}{10}[/tex]

Step-by-step explanation:

Given a quadratic in standard form, ax² + bx + c : a ≠ 0

Then the axis of symmetry is a vertical line with equation x = h

where h is the x- coordinate of the vertex.

The x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = 5x² - 3x + 5 ← is in standard form

with a = 5 and b = - 3, thus

[tex]x_{vertex}[/tex] = - [tex]\frac{-3}{10}[/tex] = [tex]\frac{3}{10}[/tex]

Thus the equation of the axis of symmetry is x = [tex]\frac{3}{10}[/tex]

Answer:

(4,3)

Step-by-step explanation:

3x + 2y = 18

5x – 2y = 14

Add the two equations together to eliminate y

3x + 2y = 18

5x – 2y = 14

------------------------

8x    =   32

Divide each side by 8

8x/8 = 32/8

x = 4

Now determine the value for y

3(4) +2y = 18

12 +2y =18

Subtract 12 from each side

12-12+2y = 18-12

2y = 6

Divide by 2

2y/2 =6/2

y=3

Answer:

x=4 and y=3

Step-by-step explanation:

x+2y=18

5x−2y=14

Add these equations to eliminate y:

8x=32

Then solve8x=32for x:

8x=32

8x

8

=

32

8

(Divide both sides by 8)

x=4

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

3x+2y=18

Substitute4forxin3x+2y=18:

(3)(4)+2y=18

2y+12=18(Simplify both sides of the equation)

2y+12+−12=18+−12(Add -12 to both sides)

2y=6

2y

2

=

6

2

(Divide both sides by 2)

y=3

Answer:

x=4 and y=3

Answer:

29.33π cm³  or 92.10 cm³

Step-by-step explanation:

To find the volume of a cone with height 5.5 and radius 4, we will simply use the formula;

volume of a cone = [tex]\frac{1}{3}[/tex] π r² h

h = 5.5  and r= 4, we will simply plug in these values into our formula

volume of a cone  =  [tex]\frac{1}{3}[/tex]   ×  π   × (4)² (5.5)

                               = [tex]\frac{1}{3}[/tex]  ×π × 16 × 5.5

                                =88π   /  3

                                 =29.33π

volume of cone = 29.33π

But π= 3.14

plugging in π=3.14, we have;

volume of cone = 29.33(3.14)=29.10

By using the formula (Area = Length x Width) we can rearrange the equation to find the height of the rectangular poster. It comes out to be 4 feet.

To answer your question, we must use the formula for the area of a rectangle, which is Area = Length x Width. Here, the area of the poster is given as 38 square feet and the width is 9.5 feet. The length is what we're trying to find. We can set this up as an equation 38 = Length x 9.5. To find the Length, we divide both sides of the equation by 9.5 resulting in Length = 38 ÷ 9.5. Solving the equation gives us a length of approximately 4 feet. So, the 'height' of the poster would be 4 feet.

The theoretical probability of getting a 2 when a fair die is rolled is 1/6  so its a low chance

Step-by-step explanation:

In math, a loss of $20 is represented by the negative integer -20. The negative in front of the 20 represents the loss or decrement.

In mathematics, integers are whole numbers that can be either positive, negative, or zero. When we talk about a loss or decrement of something, it's universally symbolized with a negative integer.

In case of a loss of $20, it is represented as -20, where the negative sign indicates the loss or subtraction of money.

Answer:

.3-.6 ; 0-.6 ; .1-.3 ; 0-.3 ; 0-.1

Step-by-step explanation:

The "points" are:

(0,96.44), (.1,97.6), (.3, 98.57), and (.6, 98.3)

The "rate of change" is the slope. This means that the change from...

0-.1 is (97.6-96.44)/.1 = 1.16/.1= 11.6

0-.3 is (98.57-96.44)/.3 = 2.13/.3 = 7.1

0-.6 is (98.3-96.44)/.6 = 1.86/.6 = 3.1

.1-.3 is (98.57-97.6)/.2 = .97/.2 = 4.85

.3-.6 is (98.3-98.57)/.3 = -.27/.3 = -.9

Answer:

∠CBD = 54°

Step-by-step explanation:

∠ABC = 90°

∠ABD + ∠CBD = ∠ABC

4X + 7X -9 = 90

11X = 90+9

11X = 99

X = 99/11

X=9°

∠CBD = (7X -9)° = 7 * 9 - 9 = 63-9 = 54°

Answer:

C

Step-by-step explanation:

We can solve simultaneous equations using substitution method, elimination method or graphical method. But for this purpose, we will be using the elimination method.

3x+4y=8 Equation 1

2x+y=42 Equation 2

Multiply Equation 1 by 2 and equation 2 by 3, so as to get the same coefficient for x

2(3x+4y=8)= 6x+8y=16 Equation 3

3(2x+y=42)= 6x+3y=126 Equation 4

Subtract equation 4 from 3, to eliminate x

6x-6x=0

8y-3y= 5y

16-126= -110

We now have 5y=-110

Divide both sides by 5,

y= -110/5

= -22

Substituting for y in equation 2

2x+(-22)= 42

2x= 42+22

2x=64

x= 64/2

= 32

(x, y)

(32, -22)
