Find the exponential function that satisfies the given conditions:
swat32

<u>Answer-</u>

<em>The exponential function that satisfies the given conditions is f(t)=67(0.9953)^t</em>

<u>Solution-</u>

This can be represented as exponential decreasing function,

f(t)=a(1 - r)^t

Where,

  • a = starting amount = 67
  • r = rate = 0.47% = 0.0047
  • t = week

Putting the values,

\Rightarrow f(t)=67(1 - 0.0047)^t

\Rightarrow f(t)=67(0.9953)^t

Therefore, the exponential function that satisfies the given conditions is

f(t)=67(0.9953)^t

AB and BC form a right angle at point B. If A=(-3,-1) and B=(4,4), what is the equation of BC
poizon [28]

Answer:

(C) -7x − 5y = -48

Step-by-step explanation:

We look for the equation of the line AB

We have then:

y-yo = m (x-x0)

m = (y2-y1) / (x2-x1)

m = (4 - (- 1)) / (4 - (- 3))

m = 5/7

We choose an ordered pair:

(xo, yo) = (4, 4)

Substituting:

y-4 = (5/7) (x-4)

y = (5/7) x-20/7 + 4

7y = 5x - 20 + 28

7y = 5x + 8

y = (5/7) x + 8/7

The equation of the perpendicular line is:

-7x - 5y = -48

Answer:

the equation of BC is:

(C) -7x - 5y = -48
