While traveling along a highway a driver slows from 24 m/s to 15 m/s in 12 seconds. What is the automobile’s acceleration? (Re

member that a negative value indicates slowing down or deceleration)

We are given that:

vi, initial velocity = 24 m/s

v, final velocity = 15 m/s

t, time = 12 s

 

The formula for acceleration is:

a = (v – vi) / t

a = (15 – 24) / 12

<span>a = - 0.75 m/s^2                                (deceleration)</span>

The equation x ^ 2 - 2x + y ^ 2 - 4y = 20 defines a circle in the xy-coordinate plane What is the radius of the circle?
Helga [31]

Answer:

I'll set up the problem and you can do the calculation

Step-by-step explanation:

we need to complete the squares to get the equation in the general form:

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

where h = the x coordinate of the center

k = the y coordinate of the center

r = the radius

so looking at

{x}^{2}  - 2x

we can see that if use -1 as the constant we have

{(x - 1)}^{2}  =  {x}^{2}  - 2x   + 1

doing the same for y

{y}^{2}  - 4y

we can use -2 as the constant (basically you that the s

quare of the y coefficient )

{(y - 2)}^{2}  =  {y}^{2}  - 4y   + 4

so now we have to add or subtract the constant on the RHS to see what the square of the radius is according to the general form of the equation at the top

20 +1+4=25

Take the square root and you have the radius

As you can see, angle 5 and angle 6 are supplementary.  And angle 5 and angle 3 are congruent because they are alternate interior angles.  

So it will be
x+2 = 180- x+3 
                         move x over from the right to the left
2x+2 = 183
                         move 2 over from the left to the right
2x = 181
                          divide by 2
x= 90.5

and angle 3 and angle 1 are vertical angles so they are congruent.  Using the angle 3 formula to solve for the answer:

90.5+3 =93.5

When angles are congruent, their measures are congruent, therefore, measure of angle 1 is 93.5

So i'm really confused how do you get 3 5/12 in this question? Manson bought 8 1/4 feet of wire. He cut off a piece of wire 3 5/
GaryK [48]

Answer:

r = π C , C = 12 − x , t h e n r = π ( 12 − x ) = 12 π − π x

Step-by-step explanation:

So cutting the wire of 12 m in length into two pieces, x and 12-x. The x side will be made into the square so that the square has sides x/4 and an area of (x/4)^2. This means the length of the wire 12-x will be the circumference of the circle. So if: r = π C , C = 12 − x , t h e n r = π ( 12 − x ) = 12 π − π x i hope this is correct
