Select the correct answer.

DedPeter [7]

Answer: The correct option is (D) (4, -6).

Step-by-step explanation: Given that the areas of the triangles ADC and DCB are in the ratio 3 : 4.

We are to find the co-ordinates of point C.

From the diagram, we note that

the co-ordinates of point A and B are A(1, -9) and B(8,-2).

So, the length of the line segment AB, calculated by distance formula, is

$AB=\sqrt{(1-8)^2+(-9+2)^2}=\sqrt{49+49}=7\sqrt2.$

Now, area of ΔADC is

$A_{ABC}=\dfrac{1}{2}\times AC\times CD,$

and area of ΔDCB is

$A_{DCE}=\dfrac{1}{2}\times BC\times CD.$

According to the given information, we have

$A_{ADC}:A_{DCB}=3:4\\\\\\\Rightarrow \dfrac{A_{ADC}}{A_{DCE}}=\dfrac{3}{4}\\\\\\\Rightarrow \dfrac{\frac{1}{2}\times AC\times CD}{\frac{1}{2}\times BC\times CD}=\dfrac{3}{4}\\\\\\\Rightarrow \dfrac{AC}{BC}=3:4.$

So, the point C divides the line segment AB internally in the ratio 3 : 4.

We know that

if a point divides a line segment with end-points (a, b) and (c, d) internally in the ration m : n, then its co-ordinates are

$\left(\dfrac{mc+na}{m+n},\dfrac{md+nb}{m+n}\right).$

Since point C divides the line segment AB with end-points A(1, -9) and B(8, -2) internally, so the co-ordinates of point C will be

$\left(\dfrac{3\times 8+4\times 1}{3+4},\dfrac{3\times (-2)+4\times (-9)}{3+4}\right)\\\\\\=\left(\dfrac{28}{7},\dfrac{-42}{7}\right)\\\\\\=(4, -6).$

Thus, the co-ordinates of point C are (4, -6).

Option (D) is correct.

Question 35 I need help with .

iogann1982 [59]

Ok in 2001 the Barnes had 45,000, and 12% was dedicated to savings.

in 2002 their income went up by 10%, 10% of what? well, 10% of 45000, how much is that? well, 10% of anything is just (10/100) * anything

so 10% of 45000 is (10/100) * 45000 or just 4500, you simply chop off a zero

so, it went from 45000 to 45000 + 4500 or 49500

now, they do their budget the same, savings is 12% in 2002, just like in 2001, alrite, how much is 12% of 49500? well, 12% of anything is just (12/100) * anything

so... I'm sure you'd know how much (12/100) * 49500 is

Choose the correct simplification of f^9 h^23/f^3 h^17

Tanzania [10]

Answer:

f6h40

Step-by-step explanation:

Step 1 :

h23

Simplify ———

Equation at the end of step 1 :

h23

((f9) • ———) • h17

Step 2 :

Multiplying exponential expressions :

2.1 h23 multiplied by h17 = h(23 + 17) = h40

Final result :

f6h40
