We know the y intercept is 16 because y=16 when x=0.
Find slope by calculating change in y over change in x.
(12-16)/(2-0)
-4/2
-2
Plug both values into slope intercept form. y=mx+b where m is slope and b is the y intercept.
Final answer: y=-2x+16
Answer:

Exponential decay
Step-by-step explanation:
We are given that

y=20 when t=0

Taking integration on both sides then we get

Using formula

Using formula




Substitute y=20 and t=0

Substitute the value of C

When t tends to infinity then

When time increases then the value of function decrease
Hence, the function is exponential decay.
Answer:
r = 6cm
Step-by-step explanation:
The area of a circle is given by
A = pi r^2 where r is the radius
36 pi = pi r^2
Divide each side by pi
36 pi/pi = pi r^2/ pi
36 = r^2
Take the square root of each side
sqrt(36) = sqrt(r^2)
6 =r
The radius is 6 cm
r = 6cm
Please make it more clear, i cant really seee the question
Wdym that’s really confusing do u mean -7 times 9= -63
