It is about :<br>Length of line segment in the rectangular coordinate system

ella [17]

If a segment is horizontal, its length is the difference between its x coordinates. If the result is negative, you need to consider the absolute value (or just pick the coordinates in the correct order, i.e. the bigger minus the smaller).

So, we have

$CD = D_x-C_x=6-1=5$

$EF = F_x-E_x=-2-(-8)=-2+8=6$

Write the general equation for the circle that passes through the points: (1, 7) (8, 6) (7, -1)

Naddika [18.5K]

Answer:

$x^{2} +y^{2} +(-8)\times x+ (-6)\times y = 0$

Step-by-step explanation:

General equation of circle is $x^{2} +y^{2} +2\times g \times x+2\times f\times y+c = 0$ ---------------------(1)

This circle passes through the given three points, (1,7) , (8,6) and (7,-1).

Substitute (1,7) in (1),

1 + $7^{2} +2\times g\times 1 + 2\times f\times 7 +c$ =0

2g + 14f + c = -50 -------------(2)

Substitute (8,6) in (1),

$8^{2} + 6^{2} +2\times g \times 8+2\times f\times 6 +c=0$

16g + 12f + c = -100 -----------(3)

Substitute (7,-1) in (1),

$7^{2} + (-1)^{2} +2\times g \times 7+2\times f\times (-1) +c=0$

14g - 2f + c = -50 ---------------(4)

Solving (2),(3) amd (4) simultaneously,

g = -4

f = -3

c = 0

Equation of circle is

$x^{2} +y^{2} +(-8)\times x+ (-6)\times y = 0$

A botanist uses the representations below to show the heights in inches, h, of different plants over a period of time, t.

yawa3891 [41]

At 120 weeks, ...
• the table tells you plant A is 180 inches tall
• the function tells you plant B is 4·120/3 = 160 inches tall
• the graph tells you plant C is 360 inches tall.

The tallest plant is 360 inches tall; the shortest is 160 inches tall. Their difference in height is
... 360 in - 160 in = 200 inches

Bruce evaluates the expression on a math quiz, 8.8 ÷ 2.7 and gets an answer of 4.14.

IgorLugansk [536]

The most reasonable answer is D.

8.8 will round to 9 and 2.7 will round to 3, and the division will round to 3. Bruce's answer rounds to 4, so his answer is not reasonable.
