find the solutions of the quadratic equation 3x^2-2x+7=0
PLEASE ANSWER CORRECTLY!!

Hey there!

“2 (5x + 3)”

• FIRST and ONLY STEP: DISTRIBUTE 2 to ALL OF YOUR NUMBERS in the parentheses

2(5x) + 2(3)

2(5x) = 10x ⬅️ FRONT number

2(3) = 6 ⬅️ BACK number

BOTH OF YOUR NUMBERS ARE POSITIVE SO WE DON’T HAVE TO CHANGE ANYTHING

Answer: 10x + 6 ☑️

Good luck on your assignment and enjoy your day!

Answer:

10x+6

Step-by-step explanation:

Answer:

y = -x + 10 I believe.....

Answer:

1. 0, 2 π , π , 2 π/3 , 4 π/3

2. 7 π/6 , 11 π/6

Step-by-step explanation:

1. we want to find the value of theta

Let us represent theta by x for ease of documentation

So we have ;

sin 2x + sin x = 0

Mathematically;

sin 2x = 2sinxcosx

So;

2 sin x cos x + sin x = 0

sin x (2 cos x + 1) = 0

sin x = 0

or

2cos x + 1 = 0

x = arc sin (0)

within the given range;

x = theta = 0 , 2 π , π

For;

2 cos x + 1 = 0

2cos x = -1

cos x = -1/2

cos x = -0.5

x = arc cos (-0.5)

x = 2 π/3 , 4 π/3

2. cos 2 x = 1 + sin x

Mathematically;

cos 2 x = 1-2 sin^2x

let sin x = y

1-2y^2 = 1 + y

y = -2y^2

1 = -2y

y = -1/2

y = -0.5

sin x = y

sin x = -0.5

x = arc sin (-0.5)

x = 7 π/6 , 11 π/6

Answer:

D. 11655

Step-by-step explanation:

First find the 90th term:

a90=a1+(n−1)d      

 = -4+89(3)=263

Then find the sum:

Sn = n(a1 + an) / 2

S90 = 90 (-4 + 263) /2

S90 = 23,310/2

S90 = 11,655

Answer:

d / 2

Step-by-step explanation:

60.2

Step-by-step explanation:

a^2 + b^2 = c^2

40^2 + 45^2 = c^2

1600 + 2025 = c^2

3625 = c^2

the square root of 3625 is 60.2

Answer:

60.2 metres

Step-by-step explanation:

Pythagoras formula = square of b plus squar of c = square of a

let b be 40 and let c be 45

40^2 + 45^2 = a^2

1600 + 2025 = a^2

3625 = a^2

square root of 3625 = a

60.2 meters = a

Answer: 33.3% increase, pretty sure

Step-by-step explanation: Big number- Small number, and then divided by the first number: 44-33=11. 11 divided by 33 ( original) is 0.3333, and then change the decimal to a percent, which is 33.3%.

Answer:

9 years

Step-by-step explanation:

Let the present age = x

Age 6 years ago = x - 6

Thrice my age 6 years ago = 3*(x -6) =3x - 3*6 = 3x - 18

Twice my present age = 2 *x = 2x

Thrice my age 6 years ago be subtracted from

twice my present age  = 2x -  (3x - 18)

2x - (3x - 18) = x

2x - 3x  + 18 = x                  

    -x  + 18 = x              {Add x to both sides}

             18 = x + x

              18 = 2x              {Divide both sides by 2}

           18/2 = x

x = 9 years

Answer:

x = 107

Step-by-step explanation:

The exterior angle and the interior angle make a supplementary angle.

This means it is 180°. Knowing this, we can solve for x:

73 + x = 180

x = 107

Therefore, x = 107.

Answer:

s+[tex]\sqrt{f}[/tex]

Step-by-step explanation:

Sum means plus, so s plus the square root of f. The sign for square root is [tex]\sqrt{}[/tex], so s+[tex]\sqrt{f}[/tex] is the correct answer.

Answer:

17

Step-by-step explanation:

Answer:

17

Step-by-step explanation:

12/1/2 - (-4/1/2) becomes 12 1/2 + 4 1/2 after simplification.  Note that 12/1/2 is invalid.

Combining 12 1/2 and 4 1/2 yields 17.

3 batches of chocolate chip with 2 cups per batch is 6 cups total for the chocolate chip cookies.

Subtract the total needed for the chocolate chip from the total flour used, then divide the remaining amount by number of batches of oatmeal

Cookies.

The problem show 122 total cups, but I don’t think that is right... what is the actual total cups used?

Step-by-step explanation:

1 week = 7 days

Therefore 1 week = 60,000 letters

=> 7 days = 60,000 letters

=> 1 day = 60,000 / 7 = 8571.4... letters

Hence Obama receives around 8,571 letters per day.

Answer:

ST = 3 units

Step-by-step explanation:

From the number line attached in the picture,

Distance of S from 0 = 7 units

Distance of T from 0 = 4 units

Therefore, distance between S and T = 7 - 4

ST = 3 units

[Note : Length of a segment is always positive so ST can't be negative]
