Solve for x. Round to the nearest tenth of a degree, if necessary.​
MissTica

Answer:

x ≈ 54.8°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = \frac{opposite}{adjacent} = \frac{PQ}{QR} = \frac{7.1}{5} , then

x = tan^{-1} (\frac{7.1}{5} ) ≈ 54.8° ( to the nearest tenth )

A number hidden by spilt ink multiplied by 12 equals sixteen thousand, eight hundred and thirty-six. Sixteen thousand, eight hun
Nezavi [6.7K]

Answer:

12

Step-by-step explanation:

Assume the hidden number is x;

So, if  x*12= 16,836

Next, divide both sides by 12 to solve for x;

x= 16,836 / 12

x= 1,403

So the number hidden by spilt ink is 1,403.

Next, to answer the question, divide 16,836 by the hidden number,1403;

16,836 / 1403 = 12

Therefore, it will be equal to 12 which is basically the reverse of the first equation.

How do you anwser on cube root
12345 [234]

to answer on cube root we need to use the prime factorisation.

which means using only prime number and dividing the number by suitable prime number.

after find prime factorisation we know that cube root is 3th power of number.

so if we have same three number we need to take it as one because it is a cube root .

for example\sqrt[3]{5*5*5} =\sqrt[3]{5^3} =5.

The factors of a quadratic function are 2x-3 and x-3. what is the axis of symmetry of this function?
Crank
F : R -> R, f(x) = ( 2x - 3)( x - 3 ) => f(x) = 2x^2 - 9x + 9;
The axis of symmetry is x = - b / (2a) => x = 9 / 4.

Find the exact solution of x. 3x² + 7 = 28 ( square root)
Schach [20]

Answer

The exact solution of  x is 2.65  for the given equation 3x² + 7 = 28 .

Step-by-step explanation:

The equation given in the question is as follows.

3x² + 7 = 28

Now simplify the above eqaution

3x² = 28 - 7

3x² = 21

x^{2} = \frac{21}{3}

x² = 7

x = \sqrt{7}

x = \sqrt{7}

x = 2.65

Therefore the solution for x is 2.65  for the given equation 3x² + 7 = 28 .
