In this case, the troupe raised the price by too much.

The T-shirts were selling better at the lower price, therefore they could make more of a profit. However, when they raised the prices, the demand for the shirts went lower.

It could possible be due to the high price. Also, perhaps everyone already had shirts and they didn't want to buy anymore.

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

Point A is at (-1,-9) and Point B is at (2,4). What is the midpoint of line segment AB

Mkey [24]

Answer:

Midpoint( .5,-2.5)

Step-by-step explanation:

To find the midpoint, add the x coordinates and divide by 2 and then add the y coordinates and divide by 2

x: (-1+2)/2 = 1/2=.5

y: (-9+4)/2 = -5/2 = -2.5

Midpoint( .5,-2.5)
