16.40

Step-by-step explanation:

use Pythagorean theorem

Answer:

x= 1 ±√21/3

x= 2.52753

x= - 0.527525

Step-by-step explanation:

-(-6) ±√-6² - 4 (3) (-4) / 2(3)

6±√36 -(-48) / 6

6±√84/6

6±2√21/6

6/6 ±2√21/6

1±√21/3

1+ √21/3 = 2.52753

1-√21/3= - 0.527525

Step-by-step explanation:

[tex]3x ^{2} - 6x - 4 = 0[/tex]

[tex]by \: quadratic \: formula[/tex]

[tex](-b±√(b²-4ac))/(2a) [/tex]

[tex] - ( - 6)±√( - 6²-4(3)( - 4) /(2 \times 3) [/tex]

[tex](6±√(36 + 48)/(6) [/tex]

[tex](6±√(84)/(6) [/tex]

[tex](6±2√21)/6[/tex]

[tex]2(3±√21)/6 [/tex]

[tex]3±√21/3[/tex]

[tex]let \: \alpha \: and \: \beta \: be \: two \: roots \: .[/tex]

[tex]3 + \sqrt{21} /3[/tex]

[tex]3 + 4.58/3[/tex]

[tex]7.48/3[/tex]

[tex]2.52[/tex]

[tex]and \: second \: root \: = 3 - \sqrt{21} /3[/tex]

[tex]3 - 4.58/3[/tex]

Answer:

6.403124

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

given 9x-12=3x we want to solve for x

To do so we need to isolate the variable using inverse operations

to get rid of the 9x we subtract each side by 9x

9x - 9x  cancels out

3x - 9x =-6x

now we have

-12=-6x

now we want to get rid of the -6

to do so we divide each side by -6

-6x/-6=x

-12/-6=2

we're left with x=2

Answer:

9x=3x+12

9x-3x=12

9x-3x=12

6x=12

x=2

solution

x=2

Answer:

What?

Step-by-step explanation:

Answer:

the answer would be 18.28

Step-by-step explanation:

if you times 0.914 x 20

which would make 20 yards

because 0.914 is only 1 yard

Required picture attached below :

Answer:

2 1/4 inches

Step-by-step explanation:

From the line plot Given ;

The frequency or number of 3/4 inch button is 3

Therefore, lining up all the 3/4 inch button in the plot, we have :

3/4 + 3/4 + 3/4

(3 + 3 + 3) /4

9 /4

2 1/4 inch

I believe this is correct! Good luck :)

Theoretical Probability:

P(rolling a 2) = 16.7%

P(rolling a 5) = 16.7%

P(rolling 2 or 3) = 33.4%

P(greater than 4) = 33.4%

P(3 or less) = 50.1%

Experimental Probability:

P(rolling a 2) = 20%

P(rolling a 5) = 6%

P(rolling 2 or 3) = 36%

P(greater than 4) = 24%

P(3 or less) = 54%

Explanation:

Theoretical probability can be calculated based on the idea that each of the six numbers on the die has an equal chance of being rolled and all numbers' probabilities total to 100%. Experimental probability is based on the outcomes of your experiment (rolling the dice yourself).

When finding the probability of rolling a number or another number (for example, rolling a 2 or 3), just add the probabilities together (You rolled 2 ten times and 3 eight times, so the experimental probability of rolling a 2 or 3 is 18/50 = 36%)

Answer:

Step-by-step explanation:

It is the 3rd or 1st one.

Answer:

y = 0.01 * 2ˣ

Step-by-step explanation:

f(x) = xⁿ

0: 0.01 = 0.01 * 2⁰ = 0.01 * 1 = 0.01

1: 0.02 = 0.01 * 2¹ = 0.01 * 2¹ = 0.02

2: 0.04 = 0.01 * 2² = 0.01 * 2² = 0.04

Answer:

4x-2y=2

Step-by-step explanation:

Line R is represented by the following equation:

x+y=2

We need to choose another system of equation of x+y=2

whose solution is (1,1)

The equation must be satisfy the point (1,1)

Option 1: 2x+y = 2

Put x=1 and y=1

2(1)+1 = 3

3 ≠ 2

False

Option 2: 4x-2y=2

Put x=1 and y=1

4(1) - 2(1) = 2

2 = 2

True

Option 3: 2x-2y=2

Put x=1 and y=1

2(1) - 2(1) = 0

0 ≠ 2

False

Option 4: x+y=4

Put x=1 and y=1

1+1 = 2

2 ≠ 4

False

Hence, The system of equation is 4x-2y=2

Answer:

Step-by-step explanation:

The sum of a triangle’s angles is always 180 degrees so

x+x+25=180

2x+25=180

2x=155

x=77.5 degrees

Answer:

The surface area of the given pyramid is 112 [tex]inches^{2}[/tex].

Step-by-step explanation:

Base length of the pyramid = 4 inches

Area of the base = [tex]length^{2}[/tex]

                            = [tex]4^{2}[/tex]

                            = 16

Area of its base = 16 [tex]inches^{2}[/tex]

Area of one of its triangular surface = [tex]\frac{1}{2}[/tex] x base x height

                                 = [tex]\frac{1}{2}[/tex] x 4 x 12

                                 = 2 x 12

                                 = 24 [tex]inches^{2}[/tex]

Area of all its four triangular surfaces = 4 x 24

                                                       = 96 [tex]inches^{2}[/tex]

surface area of the pyramid = sum of areas of all its surfaces

                                               = 16 + 96

                                       = 112 [tex]inches^{2}[/tex]

The surface area of the given pyramid is 112 [tex]inches^{2}[/tex].

Answer:

-512

Step-by-step explanation:

The appropriate general formula for a geometric series is a(n) = a(1)*r^(n - 1).

In this problem the first term, a(1) = 1, and the common ratio is r = -2.  The pertinent geometric series is thus:

a(n) = (-2)^(n - 1), and the 10th term is a(10) + (-2)^(10 - 1) = -512 = a(10)
