gladu [14]4 years ago
3 0

Since C is the centroid, therefore:

Segments PZ = ZR;  RY = YQ; QX = XP<span>

<span>A.
If CY = 10, then</span></span>

PC = 2*CY = 20<span>
PY = PC + CY = 20 + 10 = 30
Answer:      PC = 20</span>      PY = 30

B.
If QC = 10, then

ZC = QC/2 = 5<span>
ZQ = ZC + QC = 5 + 10 = 15
Answer:      ZC = 5</span>        ZQ = 15

<span>C.
<span>If PX = 20
Because the median RX bisects side PQ, therefore PX = QX = 20
PQ = PX + QX = 40
Answer:      <span>PQ = 40</span></span></span>

What is the equation of the line that passes through (–2, 4) and is perpendicular to 2x + 3y = –6?
MA_775_DIABLO [31]
So you want to get it to slope intercept for.
y = (-2/3)x -2
when you want a perpendicular slope, the slope has to be flipped including the sign. 
y = 3/2x
this is the slope now
now you want to find the y intercept, y = mx + b
4 = 3/2 * -2 + b
4 = -3 + b 
7 =  b
y = (3/2)x + 7

Suppose you have a rectangular flower bed whose area is 24ft^2 . The shortest side is (x-4) feet and the longest side is (2x) fe
kicyunya [14]

Answer:

the short side is equal to 2 feet

Step-by-step explanation:

24 = (2x)*(x-4) = 2x² -8x

you'll just use solve on your calculator and get that the x is equal to -2 or 6

which means the short side must be equal to 2

Find a10 of the sequence 4, 28, 196, 1372
Naddik [55]

Answer:

\purple { \bold{ a_{10}=161414428}}

Step-by-step explanation:

Given sequence is: 4, 28, 196, 1372

28/4 = 7

196/28 = 7

1372/196 = 7

Since, the ratio of any two consecutive terms is same, so it is a geometric sequence.

Therefore,

Common ratio r = 7

First term a = 4

nth term of a geometric sequence is given as:

a_n=ar^{n-1} \\  \\\implies  \\  \\ a_{10}=4.7^{10-1} \\  \\ a_{10}=4.7^{9} \\  \\ a_{10}=4.7^{9} \\  \\ a_{10}=4(40353607) \\  \\   \red{ \bold{ a_{10}=161414428}}

Vinil7 [7]
The expression used to represent the amount of work done by person 1 is 1/15, whereas when it comes to person 2 it is 1/30.
You use 1/15 since it is the fifteenth of one hour.
