Answer 1



Step-by-step explanation:

If BD is an altitude, it splits triangle ABC into 2 triangles.  It is also a median, so it splits the angle ABC into 2 congruent angles.  Angle ABD and CBD are congruent.  That means that angles A and C are congruent. This is true because the 2 angles at D are both right angles.  Because of this, side AB and side CB are congruent.  That means that this is an isosceles triangle.

Which expression gives the same result as ∑4i=0(5)(1/3)i


I'm assuming which expression gives the same result as ∑^4

The second option is correct since the first option is erroneous or makes little sense. The second option and the ∑^4 are geometric progressions which will account for each other when substituted together or one into another.

Step-by-step explanation:

PLEASE HELP ME!!!! 50 points! Given the points C(-1, -3) and D(5, 6), find the coordinates of the point E on directed line segment CD that partitions CD into the ratio 2 to 1.

A. (1, 0)

B. (3, 3)

C. (-3, 3)

D. (2, 1.5)



B. (3,3)

Step-by-step explanation:

In order to find the coordinates of point E that partitions the line segment CD into a ratio of 2:1, we can use the following formula for finding the coordinates of a point that divides a line segment in a given ratio:

For a line segment with endpoints A(x1, y1) and B(x2, y2), and a division ratio of m:n, the coordinates of the point E(x, y) that divides the line segment in this ratio are given by:

\sf x =( (m* x_2 + n* x_1) )/((m + n))

\sf y =( (m* y_2 + n* y_1) )/((m + n))

In this case, we want to divide the line segment CD into a ratio of 2:1, so m = 2 and n = 1.

Wehave the coordinates of C(-1, -3) and D(5, 6).

Using the formula:

\begin{aligned} x &\sf =( (2* 5 + 1* (-1)))/( (2 + 1)) \n\n &\sf = (10-1)/(3)\n\n &\sf = (9)/(3)\n\n &\sf = 3 \end{aligned}


\begin{aligned} y &\sf =( (2* 6 + 1* (-3)) )/( (2 + 1)) \n\n &\sf = (12-3)/(3) \n\n &\sf = (9)/(3)\n\n &\sf = 3 \end{aligned}

So, the coordinates of point E that partitions the line segment CD into a ratio of 2:1 are E(3, 3).

So, the answer is B. (3,3)

Six is less than or equal to the sum of 4 and -2x


6 ≤ 4 + (-2x)
6 (-4) ≤ 4 - 2x - 4
4 and 4 cancels out
2 ≤ -2x


When you divide by a negative number, the inequality sign turns to the other side.

Again the auction house raffle sold 200 tickets at $1 each. How many prizes of $10 should they to make the raffle a fair game?


200; $1e\pp

they should sell 20 prizes

200 tickets at $1.00 each =$200 so 200 Divided by $10 is 20... The answer is 20 prizes forc$10
