Hence, the condition can be modeled by the equation

S = 20h + 3

where, S represents the score of a particular student who studied h hours before the test. (Answer)

coldgirl [10]
Treat 12 as 12/1 that means 12 divided into 1 part
1/4 times 12/1

multiply the top and the bottom becuase

\frac{x}{y} times \frac{z}{t} = \frac{x times z}{y times t} so

1/4 times 12/1=(1 times 12)/(4 times 1)=12/4=3/1=3

Can you please help me out with a question
Finger [1]

The standard equation of a circle is expressed as

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

where

h is the x coordinate of the center of the circle

k is the y coordinate of the center of the circle

r is the radius of the circle(the distance from the center of the circle to the circumference

From the graph,

h = - 1

y = 4

r = 5

By substituting these values into the equation, we have

(x - - 1)^2 + (y - 4)^2 = 5^2

(x + 1)^2 + (y - 4)^2 = 25

Thus, the equation of the circle is

(x + 1)^2 + (y - 4)^2 = 25
