Write the equation of the circle centered at (0,1) with radius 15.
NNADVOKAT [17]

Answer:

x^2+(y-1)^2=225

Step-by-step explanation:

we know that

The equation of the circle in center radius form is equal to

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

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have

(h,k)=(0,1)\\r=15\ units

substitute

(x-0)^2+(y-1)^2=15^2

x^2+(y-1)^2=225

the function y = 3.75 + 1.5(x - 1) can be used to determine the cost in dollars of x miles. What is the rate of change of the co
LenKa [72]

We are given

y=3.75+1.5(x-1)

where

y is the cost in dollars

x is distance in dollars

now, we can find derivative

y'=\frac{d}{dx}\left(3.75+1.5\left(x-1\right)\right)

=\frac{d}{dx}\left(3.75\right)+\frac{d}{dx}\left(1.5\left(x-1\right)\right)

=0+1.5

so,

y'=0+1.5

So,

the rate of change of the cost in dollars with respect to the number of miles is 1.5.........Answer

Which transformations are needed to change the parent cosine function to y= 3cos(10(x-pi) )?
denpristay [2]
<span>The parent cosine function can be transformed and translated. So, from the basic function cos(x) we can obtain function acos(bx+c). In our case, a=3- amplitude, b=10- the period change and c=-pi- the phase shift. So, the parent cosine function is mutiplied with 3 (which gives the amplitude of the function, 3*0.5=1.5). The period of the function is changed, and is 2pi/b=2pi/10=pi/5 and the cos(x) is phase shifted for c/b=-pi/10.</span>
