Write N as a discrete exponential function of t of the form N(t)=A(1+r)t. (HINT: You will need to find (1+r), where r is the rat
Whitepunk [10]

Answer:

N(t)=84(1+0.0405)^t.

Step-by-step explanation:

We have been given that N(11)=130 and N(0)=84. We are asked to write N as a discrete exponential function of t of the form N(t)=A(1+r)^t.

Using our given information, we can set an equation as:

N(0)=A(1+r)^0

84=A*1

84=A

Using our given information, we will get:

N(11)=A(1+r)^{11}

Substitute the given values:

130=84(1+r)^{11}

\frac{130}{84}=\frac{84(1+r)^{11}}{84}

1.5476190476190476=(1+r)^{11}

Switch sides:

(1+r)^{11}=1.5476190476190476

Take 11th root of both sides:

\sqrt[11]{(1+r)^{11}}=\sqrt[11]{1.5476190476190476}

1+r=1.04050024747304

r=1.04050024747304-1

r=0.04050024747304

r\approx 0.0405

Therefore, our required function would be N(t)=84(1+0.0405)^t.

Which equation is in point-slope form for the given point and slope?
Neko [114]
First,we need to understand the point-slope form:
y1 - y2 = m(x1 - x2)
Where x and y are the coordinates and m is the slope.

Put the above information into the equation:

y-(-6)=-3/4(x-2)
y+6 = -3/4 (x-2)

Therefore the answer is C.y+6 = -3/4 (x-2).

Hope it helps!
