Answer:

f^{-1}(3)=2 is correct

Step-by-step explanation:

Given the function f(x) = \log_2(x + 6)

We need to find f^{-1}(3)

First we find the inverse of the function

y= \log_2(x + 6)

Switch x and y

x= \log_2(y + 6)

Solve for y

2^x=y + 6

y=2^x-6

\therefore, f^{-1}(x)=2^x-6

Put x=3

f^{-1}(3)=2^3-6\Rightarrow 8-6=2

Thus, f^{-1}(3)=2 is correct

Point R is the midpoint of line QS. R is located at (5, -7.5) S is located at (-1,-13) What is the location of Point Q?
Lisa [10]

Answer: ( 11, -2 )

Step-by-step explanation:

The mid point of a line is calculated using the formula:

M = (\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2} )

From the question , the mid point is already given , substituting , we have :

(5 , - 7.5 ) = (\frac{x-1}{2} , \frac{y-13}{2} )

Equating the x component to x and the y component to y , we have

5 = \frac{x-1}{2}

x - 1 = 10

x = 11

Also

- 7.5 = \frac{y-13}{2}

-15 = y - 13

-15 + 13 = y

Therefore : y = -2

Therefore : the location of point P is ( 11, -2 )

Find the equation of the tangent to the circle x2 + y2 = 109 at point (-10,3)
konstantin123 [22]

Answer:

10x - 3y = -109 .

Step-by-step explanation:

x^2 + y^2 = 109

Implicit Differentiation:

2x + 2y.y' = 0

y' = -2x/2y = -x/y

So at the point (-10,3) the gradient of the tangent is -(-10)/3 = 10/3.

Equation of the tangent:

y - y1 = m(x - x1)

y - 3 = 10/3(x + 10)

y - 3 = 10/3 x + 100/3

3y - 9 = 10x + 100

-109 + 3y = 10x

10x - 3y = -109
