15. In triangle ∆PQR, C is the centroid.

Dmitrij [34]

Because 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>

Find the average rate of change of f(x) = 2x2 – 7x from x = 2 to x=6.

Masteriza [31]

Answer:

<h2>-6</h2>

Step-by-step explanation:

$\text{The average rate of change of function}\ f(x)\\\text{over the interval}\ a\leq x\leq b\ \text{is given by this expression:}\\\dfrac{f(b)-f(a)}{b-a}\\\\f(x)=2x^2-7x\\\\\text{Put the values of x = 2 and x = 6 to the equation of the function:}\\\\f(2)=2(2^2)-7(2)=2(4)-14=8-14=-6\\f(6)=2(6^2)-7(6)=2(36)-42=72-42=-30\\\\\dfrac{f(6)-f(2)}{6-2}=\dfrac{-30-(-6)}{4}=\dfrac{-24}{4}=-6$
