Initially, there are 4^2 fish living in a lake. The population will quadruple every month. The number of fish present after t months can be expressed with the formula p= 4^2x 4^t a. Find the population of fish in the lake after 11 months as a power of 4.
b. If an illness kills 1/4^3 of the fish, how many will remain? Write your answer as a power of 4.

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
