Answer:

$\Large \boxed{r =\frac{v^2 }{a}}$

Step-by-step explanation:

$\displaystyle a=\frac{v^2 }{r}$

We need to rearrange and solve the formula for $r$ .

Multiply both sides of the equation by $r$ .

$\displaystyle a \times r=\frac{v^2 }{r} \times r$

Simplify the equation.

$ar=v^2$

Divide both sides of the equation by $a$ .

$\displaystyle \frac{ar}{a} =\frac{v^2 }{a}$

Simplify the equation.

$\displaystyle r =\frac{v^2 }{a}$

The local radio tower is located 20 miles east and 12 miles north of Pamela's cabin. The radio tower has a 25 mile broadcast rad

pychu [463]

Answer:

x^2 +y^2 -40x -24y -81 =0

Step-by-step explanation:

We can write the equation of a circle in the form

(x-h)^2 + (y-k)^2 = r^2

Where (h,k) is the center and r is the radius

Assuming that Pamela's cabin is the center

( x-20)^2 + (y- 12)^2 = 25^2

We want to get to general form

x^2 + y^2 + Dx + Ey + F = 0,

Distributing

x^2 -40x +400 + y^2 -24y +144 = 625

x^2 +y^2 -40x -24y +544 -625 =0

x^2 +y^2 -40x -24y -81 =0

If f(x) = x^2 – 25 and g(x) = x – 5, what is the domain of (f/g)(x)

daser333 [38]

(f/g)(x) = (x^2-25)/(x-5) = x+5. So domain will be R, all real numbers

How to do this? (#21 and #23)

Readme [11.4K]

Answer:

$\large\boxed{21.\ g(x)=f(x-2)+1\to g(x)=\log_3(x-2)+1}\\\\\boxed{22.\ g(x)=f(x)-4\to g(x)=3^x-4}\\\\\boxed{23.\ g(x)=-f(x)\to g(x)=-\log_{\frac{1}{2}}x}$

Step-by-step explanation:

f(x) + n - shift the grapf n units up

f(x) - n - shift the grapf n units down

f(x + n) - shift the grapf n units to the left

f(x - n) - shift the grapf n units to the right

-f(x) - reflection about the x-axis

f(-x) - reflection about the y-axis

============================================

Look at the picture.

$21.\\f(x)=\log_3x\\\\g(x)=\log_3(x-2)+1$

move the graph 2 units to the right and 1 unit up

$22.\\f(x)=3^x\\\\g(x)=3^x-4$

move the graph 4 units down

$23.\\f(x)=\log_{\frac{1}{2}}x\\\\g(x)=-\log_{\frac{1}{2}}x$

reflection the graph about the X axis.
