-16 + (-8) = -24
(-4) - 7 = -11
-24 - (-9) = -15
6.25 + (-8.50) = 2.25
10.8 - (6.4) = 4.4
-54.26 + (-15.42) = -69.68

True or false: one factor that affects the slope of the aggregate demand curve is the multiplier effect.

Alenkasestr [34]

One factor that affects the slope of the aggregate demand curve is the multiplier effect is a "true" statement.

<h3>What is aggregate demand curve?</h3>

Aggregate demand would be a macroeconomic term which refers to the total consumption of goods and services in a given period at any price level.

Some key features regarding the aggregate demand curve?

Since the two metrics are estimated in the same way, aggregate demand over time corresponds gross domestic product (GDP).
GDP is the total quantity of products and services created by an economy, whereas aggregate demand is indeed the desire or demand for those goods.
The aggregate demand as well as GDP rise or fall together as a result of using the same calculation methods.
All consumer goods, capital equipment (factories & equipment), export markets, imports, & government spending programs are included in aggregate demand.
As long as the variables trade for the same market value, they are all considered equal.

Find the area for 5 and 7

hammer [34]

Answer and Step-by-step explanation:

The area of a circle:

$A = \pi r^{2}$

d = 2r

Plug in the values.

A = $\pi 7^{2}$

A = 49 $\pi$

58 = 2r

r = 29

$A = \pi 29^{2}$

A = $841\pi$

What are the endpoint coordinates for the midsegment of △BCD that is parallel to BC?

natulia [17]

Answer:

<em>The endpoint coordinates for the mid-segment are: $(-2,-1)$ and $(1,0)$ </em>

Step-by-step explanation:

According to the given diagram, the coordinates of the vertices of $\triangle BCD$ are: $B(-3,1), C(3,3)$ and $D(-1,-3)$

Now, the endpoints of the mid-segment of $\triangle BCD$ which is parallel to $BC$ will be the mid-points of sides $BD$ and $CD$ .

<u>Formula for the coordinate of mid-point</u> : $(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})$ , where $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ are two endpoints.

So, the mid-point of $BD$ will be: $(\frac{-3-1}{2},\frac{1-3}{2})=(\frac{-4}{2},\frac{-2}{2})=(-2,-1)$

and the mid-point of $CD$ will be: $(\frac{3-1}{2},\frac{3-3}{2})=(\frac{2}{2},\frac{0}{2})=(1,0)$

Thus, the endpoint coordinates for the mid-segment of $\triangle BCD$ that is parallel to $BC$ are $(-2,-1)$ and $(1,0)$
