Answer:

x = 4cos(t) – 1 and y = 4sin(t) + 3

Step-by-step explanation:

Equation of a circle:

The equation of a circle has the following format:

(x - x_0)^2 + (y - y_0)^2 = r^2

In which:

The centre is is (x_0,y_0) and r is the radius. The parametric equations are given by:

x(t) = r\cos{(t)} + x_0

y(t) = r\sin{(t)} + y_0

In this question:

(x + 1)^2 + (y - 3)^2 = 4^2

This means that the centre is (-1,3) and the radius is 4. So, the answer is:

x = 4cos(t) – 1 and y = 4sin(t) + 3

the ages of John and Mary total 27 years. Mary's age plus twice john's age is 40. how old is each person?
son4ous [18]
So
Jon's age=j
mary age=m


m+j=27
m+2 times j=40
m+2j=40
M+j=27
ssubtract j from both sides
m=27-j
subsitute 27-j for m
27-j+2j=40
27+j=40
subtract 27 fromboth sdies
j=13

subsitue
13+m=27
subtract 13
m=14

mary=14
john=13

Find the slope and y-intercept of the line. 18x + 4y = 112 A)-9/2; 1/28 B)-2/9 ; 28 C)18; 112 D)-9/2; 28
mrs_skeptik [129]

Answer:

The slope is -9/2 and the y intercept is 28

Step-by-step explanation:

We want to put this in slope intercept form

y = mx+b where m is the slope and b is the y intercept

18x + 4y = 112

Subtract 18x from each side

18x+4y-18x = -18x+112

4y = -18x+112

Divide each side by 4

4y/4 = -18x/4 +112/4

y = -9/2x + 28

The slope is -9/2 and the y intercept is 28
