Line CD is constructed by making arcs centered at point A and point B with the same compass width.

Mathematics
1 answer:
Pavel [41]4 years ago
3 0

Answer:

C. AB=CD not necessarily true

Step-by-step explanation:

A.

AD = DB True because the width of the compass was the same and hence the radius was same for both centers A and B

B. AE=EB True

CD makes the perpendicular bisectors if arcs are made with compass of same width

C. AB=CD . There is no property which says that it is necessarily true

D. AC=CB True because the width of the compass was the same and hence the radius was same for both centers A and B

A medium can of tomato juice costs $0.92 and contains 46 ounces of tomato juice. A large can of tomato juice costs $3.60 and con
vlada-n [284]

Answer:

The medium-sized can is the cheaper by the oz, and is $0.005 per oz. cheaper.

Step-by-step explanation:

Medium can:  $0.92/(46 oz) = $0.020/oz

Large can:   $3.60 / (144 oz) = $0.025/oz

Surprisingly, the medium can price per oz. is lower than that of the large can.  The difference is $0.005 per oz.

I don’t get scientific notation. can someone help me on this?
Radda [10]
Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. It may be referred to as scientific form or standard index form, or standard. Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

Find so that the distance between (−2,3) and (,1) is √13
belka [17]

The distance between (-2, 3) and (-5, 1) is √13.

or, the distance between (-2, 3) and (1, 1) is √13.

We know that the length of the line segment connecting any two points represents the distance between them. There is just one line that connects the two points. Therefore, by measuring the length of the line segment that connects the two points, the distance between them can be determined. If (a, b) and (c, d) be two points, then the distance between them is \sqrt[]{(b - a)^{2} +(d- c)^{2} }.

Here, one point is (-2, 3).

Let the other point be (x, 1).

Given that the distance is √13.

Now, \sqrt[]{(x - (-2))^{2} +(1 - 3)^{2} } = \sqrt{13}  

i.e. \sqrt[]{(x + 2)^{2} +( - 2)^{2} } =\sqrt{13}

i.e. \sqrt[]{x^{2}+4x +4 +4 }=\sqrt{13}

i.e. x^{2}+4x +8 =13

i.e. x^{2}+4x + 8- 13=0

i.e.x^{2}+4x -5=0

i.e. x^{2} +5x - x -5=0

i.e. x(x+5)-1(x+5)=0

i.e. (x+5)(x-1)=0

i.e. x=-5,1

So, the point is either (-5, 1) or (1, 1).

Therefore, the required point is either (-5, 1) or (1, 1).

i.e. the distance between (-2, 3) and (-5, 1) is √13.

or, the distance between (-2, 3) and (1, 1) is √13.

Step-by-step explanation:

subtract the second from the first

-5x=-11

x=2=2

substituting by x in the first equation

so y=-3.4
