<h2>Question:</h2>

→Give two names for the plane?

→Name three collinear points?

→Name three coplanar points?

→Name three points?

→Name three lines?

→Name one ray?

→Name one line segment?

<h2>Answer:</h2>

Plane XYZ, Plane XZY

The points A , B and C lie on the line m . They are collinear.

The points D , B and E lie on the line n . They are collinear.

There is no line that goes through all three points A , B and D . So, they are not collinear.

The points P , Q , and R lie in the same plane A . They are coplanar .

'Line AB', 'Line BA', 'Line AC'

irina1246 [14]

Answer:

30 inches squared

Step-by-step explanation:

First, find the area of the entire frame using length times height. 9*6 is 54 inches squared. Then, find the area of the middle space the same way. 6*4 is 24 inches squared. Lastly, subtract the middle from the entire frame's area. 54-24 is 30 inches squared.

This makes no sense and I really need help on this lesson. p(c) = ?

ad-work [718]

Answer:

0.18

Step-by-step explanation:

C is a subpath of A,

first P(A) = 0.6 since the line leading to A says .6

the probability of choosing C is 0.3, but first we have to assume A is chosen. The true probability is 0.3 * 0.6 = 0.18

If $48,000 is invested in an account earning 3.1% interest compounded continuously, determine how long it will

Bas_tet [7]

Answer:

It will take about 35.439 years to triple.

Step-by-step explanation:

Recall the formula for continuously compounded interest:

$A=P\,e^{r*t}$

where "A" is the total (accrued or future) accumulated value, "r" is the rate (in our case 0.031 which is the decimal form of 3.1%), "P" is the principal, and "t" is the time in years (our unknown).

Notice also that even that the final amount we want to get is three times $48,000. So our formula becomes:

$3\,*\,48,000=\,48,000\,\,e^{0.031\,*t}\\\frac{3\,*\,48,000}{48,000} =e^{0.031*t}\\3=e^{0.031*t}$
