What is the center? (X-0.5)^2+(y-3.5)^2=16
pantera1 [17]

Answer:

(.5,3.5) is the center and 4 is the radius

Step-by-step explanation:

(X-0.5)^2+(y-3.5)^2=16

This is written in the form

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

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

(X-0.5)^2+(y-3.5)^2=4^2

(.5,3.5) is the center and 4 is the radius

Answer:

3 years 8 month

Step-by-step explanation:

Given 7 years 6 months - 3 years 10 months

Step 1: Firstly we should subtract months from months then after from year to year.

Step 2: 6 months is less than 10 months so we have to borrow 1 year and add it to the months.

Step 3: Adding 1 year to 6 months we get 18 months.

Step 4: Now we have to subtract 3 years 10 months from 6 years 18 months.

6\ years\ 18\ months-3\ years\ 10\ months=3\ years\ 8\ months

Step 5: After subtracting we get 3 years 8 months.

Thus the answer is 3 years 8 months.

1. A rabbit can hop 6 feet in 2 seconds and 12 feet in 4 seconds. If the number of feet varies directly with the time the rabbit
kykrilka [37]

Answer: The rabbit is hopping at 3 feet/ sec in speed

Step-by-step explanation:

Step 1

Let the The number of feet of the rabbit be expressed as N

AND  time rabbit spends hopping can be expressed  as  t

From the question,  The number of feet varies directly with the time rabbit spends hopping can be expressed  as

N α t

Let us introduce a constant of proportionality ,S which represents  speed in this case, we now have that

N = St

STEP 2 -- SOLVING

If the rabbit hop 6 feet in 2 seconds, Then speed =

N = St

6=  S X2

S = 6/ 2

S = 3

also

If the rabbit hop 12 feet in 4 seconds, Then speed =

N = St

12=  S X 4

S = 12/ 4

S = 3

Also recall

that Speed = Distance / time

Pluging the values in the first case,

speed = 6 feet/ 2 secconds = 3 feet/ seconds

in the second case

Speed= 12 feet/ 4 second s= 3 feet/ secs.
