PLEASE HELP: p(t)=1.8^t

Identify the initial amount "a" and the rate of growth "r" (as a percent) of the exponential function. Evaluate the function when t = 5. Round your answer to the nearest tenth

Solution:

The given exponential function is:

Where,

y is the future value

a is the initial value

r is the growth rate

t is the number of years

Compare both the functions,

a = 1

Thus growth rate is:

Substitute t = 5 in given

Thus the value is 18.9 when t = 5

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )

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)
