Answer:

D

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( where r is the radius )

Here r = 15, thus

x² + y² = 15² , that is

x² + y² = 225 → D

PLS HURRY Point S is translated 5 units to the left and 12 units up to create point S'. Find the distance between point S and po
svet-max [94.6K]

Given:

Point S is translated 5 units to the left and 12 units up to create point S'.

To find:

The distance between the points S and S'.

Solution:

Point S is translated 5 units to the left and 12 units up to create point S'.

The diagram for the given problem is shown below.

From the below figure it is clear that the distance between the point S and S' is the height of a right triangle whose legs are 5 units and 12 units.

By Pythagoras theorem,

Hypotenuse^2=Perpendicular^2+Base^2

SS'^2=(12)^2+(5)^2

SS'^2=144+25

SS'^2=169

Taking square root on both sides.

SS'=\sqrt{169}

SS'=13

Therefore, the distance between S and S' is 13 units.

The chubby bunny weighs 5 pounds, and it gains 3 pounds per year. The fat cat weighs 19 pounds, and it gains 1 pound per year. W
masya89 [10]

Answer: 7 years

Step-by-step explanation:

The Chubby bunny currently weighs 5 pounds but is increasing by 3 pounds per year. Assuming we wanted to find the weight in a given year, we can assume that given year is x. The expression would be:

= 5 + 3x

The fat cat weighs 19 pounds and gains by 1 pound a year.

Expression is:

= 19 + 1x

Equate the two equations together and find x:

5 + 3x = 19 + 1x

3x - 1x = 19 - 5

2x = 14

x = 14/2

x = 7 years
