Write an equation of the line that is perpendicular to the line y = 1 2 x + 8 that passes through the point (4,6)

Katen [24]

Answer:

$\large\boxed{y=-2x+14}$

Step-by-step explanation:

$\text{Let}\ k:y=_1x+b_1\ \text{and}\ l:y=m_2x+b_2.\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\============================\\\\\text{We have}\ y=\dfrac{1}{2}x+8\to m_1=\dfrac{1}{2}.\\\\\text{Therefore}\ m_2=-\dfrac{1}{\frac{1}{2}}=-2.\\\\\text{The equation of the searched line:}\ y=-2x+b.\\\\\text{The line passes through }(4,\ 6).$

$\text{Put thecoordinates of the point to the equation.}\ x=4,\ y=6:$

$6=-2(4)+b\\\\6=-8+b\qquad\text{add 8 to both sides}\\\\b=14$

F:x→(x+1/x+3), x≠3 and g:x→（6/x-2), x≠2, find f²(4) and g²(1/2)

Sveta_85 [38]

Answer:

$f^2(4) = (\frac{25}{49})\\g^2(\frac{1}{2} ) = 16$

Step-by-step explanation:

Here, given:

$f(x) = (\frac{x+1}{x+3} ), g(x) = (\frac{6}{x-2} )$

Now, here to find the values of $f^2(4), g^2(\frac{1}{2})$

As we know: $f^n(x) = (f(x))^n$

Now, substituting x = 4 in f(x):

$f(4) = \frac{4 +1}{4+3} = \frac{5}{7} \\\implies f^4 = (f(4))^2 = (\frac{5}{7} )^2 = \frac{25}{49} \\\implirs f^{(4)} = ( \frac{25}{49})$

Now, substituting x = 1/2 in g(x):

$g(\frac{1}{2} ) = \frac{6}{\frac{1}{2}-2} = \frac{6}{-\frac{3}{2}} \\\\ g(\frac{1}{2} ) = -6\times (\frac{2}{3} ) = -4\\\implies g^2{(\frac{1}{2}) = ( g(\frac{1}{2} ))^2 = (-4 )^2 =16 \\\\\implies g^2{(\frac{1}{2}) = 16$

13) What is the simple interest and total amount earned on $4345 with an interest rate of

Annette [7]

Answer:

173.80 interest, 4518.80 total

Step-by-step explanation:

4345 X .03(3%)=130.35/year

130.35/12=10.8625/month

10.8625 x 16 months = 173.80 interest over 16 months

4345+173.80=4518.80 total amount
