Answer:

Center (6 , -5) and radius = 3

Step-by-step explanation:

The Standard equation of circle can be written as

(x - a)² + (y - b)² = r²

with center (a , b) and radius = r

Now from given circle equation

(x - 6)² + (y +5)² = 9

so, from here center of circle (6 , -5) and radius = 3

The sum of two numbers is 48 and the difference is 20. what are the number?

rosijanka [135]

Answer:

x = 34; y = 14

Step-by-step explanation:

Step 1: Make the equations

x + y = 48

x - y = 20

Step 2: Solve the equations

x + y = 48

x - y = 20

2x = 68

x = 34

34 + y = 48

y = 14

An object moves along a coordinate axis so that its position at time t is given by s(t)=t3. Estimate its instantaneous velocity

Mademuasel [1]

If the position at time t is

s(t) = (1 m/s³) t ³

then the average velocity over t = 2 s and t = 2.001 s is

v (ave) = (s (2.001 s) - s (2 s)) / (2.001 s - 2 s)

v (ave) = ((1 m/s³) (2.001 s)³ - (1 m/s³) (2 s)³) / (2.001 s - 2 s)

v (ave) ≈ (8.01201 m - 8 m) / (0.001 s)

v (ave) ≈ 12.006 m/s
