Б) 3х2 – 10 = 152how to solve with square root​

Mathematics

Answer:

3\sqrt{6}  and  -3\sqrt{6}

Step-by-step explanation:

We will take numbers to one side and variables to one side eliminate the "Square" with "Square Root" and solve for the variable x. The process is shown below:

3x^2-10=152\\3x^2=152+10\\3x^2=162\\x^2=\frac{162}{3}\\x^2=54\\x=\sqrt{54}

Now, we need to reduce the radical by using the rule shown below:

\sqrt{x*y}=\sqrt{x}  \sqrt{y}

Now,

\sqrt{54}=\sqrt{6*9} =\sqrt{6}  \sqrt{9} =3\sqrt{6}

The correct answer is  3\sqrt{6} and -3\sqrt{6}

<u>Note:</u> squaring positive and negative makes the same answer

Answer:

13.60 See the note below.

Step-by-step explanation:

Remark

This is just the reverse of the question you just did. This time you are trying to solve for c

Givens

  • a = 8
  • b = 11
  • c = ??

Solution

c^2 = a^2 + b^2        Substitute the givens.

c^2 = 8^2 + 11^2       Expand

c^2 = 64 + 121           Combine the right side by adding

c^2 = 185                   Take the square root of both sides.

sqrt(c^2) = sqrt(185)       Complete the operation

c =  13.601                   Round to the nearest 1/100 th

c = 13.60                      Note: the zero must be there or the answer does not show the nearest 1/100 th

write an equation in slope intercept form for the line that passes through the point, and is perpendicular to the line y=-1/3x+9
aleksklad [387]

Answer:

Step-by-step explanation:

y=-1/3x+9

This is written in the format y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).

Perpendicular lines have a slope that is the negative inverse of the slope of the reference line, in this case -(1/3).  The new slope is 3.  equation is:

y = 3x + b

To find b, enter the given point, (-6,-2) and solve for b:

y = 3x + b

-2 = 3(-6) + b

-2 = -18 + b

b = 16

The full equation is y=3x + 18

( h -3 )2 for h = 5 what is it
Nookie1986 [14]

Answer: 4

Step-by-step explanation:

Substitute the value of the <u><em>variable</em></u> into the <u><em>equation</em></u> and simplify.

I evaluate and found the exact value: 4

( h -3 )2 \\h = 5

If you want me to Find the Linearization at h=5: Use the formula L(x)=f(a)+f'(a) (x-a)  to find the linearization.

Answer(Find the Linearization at h=5): L(x)=2x-6
