Part (a)

Since point E is on segment AD, this means the slope of ED is the exact same as the slope of AD.

Use the slope formula to calculate the slope of AD.

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

m = (7-2)/(4-0)

m = 5/4

<h3>Answer: 5/4</h3>

====================================================

Part (b)

The same idea and steps apply as part (a)

<h3>Answer: 5/4</h3>

====================================================

Part (c)

The x coordinates are the same, so we subtract the y coordinates to find the distance between C and D, which is the length of segment DC.

7-2 = 5

<h3>Answer: 5 units</h3>

====================================================

Part (d)

This time, the y coordinates are the same. We'll subtract the x values

4-2 = 2

<h3>Answer: 2 units</h3>

====================================================

Part (e)

Same idea as part (d), just different numbers this time.

2-0 = 2

<h3>Answer: 2 units</h3>

The answer to this question is:

A circle is growing so that the radius is increasing at the rate of 2cm/min. How fast is the area of the circle changing at the instant the radius is 10cm? Include units in your answer.?
✔️I assume here the linear scale is changing at the rato of 5cm/min
✔️dR/dt=5(cm/min) (R - is the radius.... yrs, of the circle (not the side)
✔️The rate of area change would be d(pi*R^2)/dt=2pi*R*dR/dt.
✔️At the instant when R=20cm,this rate would be,
✔️2pi*20*5(cm^2/min)=200pi (cm^2/min) or, almost, 628 (cm^2/min)

Help WHERE DID THE 10 come from

kkurt [141]

Step-by-step explanation:

It came from nowhere. It makes no sense to add up the balance numbers. To illustrate, let's use a different example:

$\left[\begin{array}{cc}Spend&Balance\\100&400\\100&300\\100&200\\100&100\\100&0\end{array}\right]$

Adding up the money you spent, and you get $500. Add up the balances, and you get $1000. But why would you add the balances? The 300 in the second line is included in the 400 in the first line. You can't add them together. You'd be counting the 300 twice.
