A race car driver holds the record for the fastest speed of 219.809 miles per hour. Part A what is 212.809 rounded to the nearest hundredth? Part B which explains how you round 212.809 to the nearest hundreth. A: Since the digit in the hundredths place is less than 5. Keep the digit in the hundreds place then drop the digit in the thousands place B:Since the digit in the thousands place is greater than or equal to the 5 increase the digit in the hundredths place by 1 then drop the digit in the thousandths place.C: Since the digit is less than 5 keep the digit in the tenths place then drop the digit in the hundredths and thousandths place. D: Since the digit in the thousands place is greater than or equal to 5 keep in the digit the hundredths place then drop the digit in the thousandths place.

1) AE = BD; CD = CE

Given

2) AE = AC + CE

Subtraction Property of Equality

3) AC +CD= BC + CD

Segment Addition Postulate

4) AC +CD= BD

Symmetric Property of Equality

5) BD = AC + CD

Segment Addition Postulate

6) BD =BC+CD

Transitive Property of Equality

7) AC = BC

Substitution Property of Equality

I think this is it

To prove that AC and BC are congruent, all usable postulates and theorems must be stated, with valid reasons.

The proof that [tex]AC \cong BC[/tex] is as follows:

Given:

[tex]AE = BD, CD= CE[/tex]

I've added as an attachment, the table that needs to be completed.

[tex]1.\ AE = BD, CD= CE \to[/tex] Given

Because the given parameters are:  

[tex]AE = BD, CD= CE[/tex]

[tex]2.\ AC \cong BC \to[/tex] Definition of congruence

[tex]3.\ AE =AC + CE \to[/tex] Segment addition postulate

From the attached image, AE is a straight line, and point C is on segment AE.

[tex]4.\ BD=AC +CD \to[/tex] Substitution property of equality

Substitute BD for AE and CD for CE in (2)

[tex]5.\ AC +CD =BD \to[/tex] Symmetric property of equality

The symmetric property of equality states that:

if [tex]a = b[/tex], then [tex]b = a[/tex]

[tex]6.\ BD =BC +CD \to[/tex] Segment addition postulate

From the attached image, BD is a straight line, and point C is on segment BD.

[tex]7.\ AC+CD =BC+CD \to[/tex] Transitive property of equality

The transitive property of equality states that:

if [tex]a = b[/tex] and [tex]b = c[/tex], then [tex]a=c[/tex]

[tex]8.\ AC =BC \to[/tex] Subtraction property of equality

Subtract CD from both sides of (6)

[tex]9.\ AC \cong BC \to[/tex] Proved

Answer:

D) |−8,000 − (−50)|

Step-by-step explanation:

When we are dealing with questions involving above or below sea level,

The formula for the Absolute value expression representing the distance = | Height above sea level -(Distance below sea level|

Height of Cameron above sea level = 8000ft = -8000

Distance of the whale below sea level = 50ft = -50

Hence, we have:

|−8,000 − (−50)|.

Answer:

63

Step-by-step explanation:

Because the two labelled angles make up a line, we know their sum is 180.

So, add them and set them equal to 180:

2x + (x - 9) = 180

Combine like terms:

3x - 9 = 180

3x = 189

x = 63

Thus, the answer is 63.

Answer:

Sure yes.

1) x > - 3 or x < 3 means that the solution set is all the numbers greater than - 3 and all the numbers smaller than 3. That is, this union of intervals: (-3,∞) U (-∞,3),  which is all the real numbers.

2) x > -3 and x <3 means that the solution set is the numbers that are at the same time greater than -3 and smaller than 3. That is the intersection of the intervals: (-3,∞) ∩ (-∞,3), which is the interval (-3, 3).

Step-by-step explanation:

looked it up and got it right on edg 2020

Answer:

Sample Response: Yes, if you change the type of compound inequality, the solution set will change. The solution set of the “and” compound inequality contains values for x that satisfy both inequalities, which are values between –3 and 3. The solution set of the “or” compound inequality contains values for x that satisfy either or both inequalities, which includes all real numbers.

Angle 1 and 3:  Vertical Angles

Angle 4 and 8: Corresponding Angles

Angles 4 and 6: Alternate Interior Angles

Angles 3 and 5: Alternate Interior Angles

Angles 7 and 8: Linear Pair

Angles 1 and 7: Alternate Exterior Angles

=================================================

Explanation:

Vertical angles are formed when you cross two lines to form an X shape. The vertical angles are opposite one another in this configuration.

Corresponding angles are ones that show up in the same corner of each four-corner crossing. In the case of angles 4 and 8, both are in the southwest corner of each four-corner crossing.

Alternate interior angles are angles in between parallel lines and on opposite sides of a transversal. Alternate exterior angles are similar, but they are outside the parallel lines.

A linear pair of angles are adjacent and supplementary (meaning they add to 180).

Answer:

Using front estimation, the cost of all the items is $450 and it will take 9 months to save enough

Step-by-step explanation:

Here, firstly we want to use front-end estimation to estimate the cost of all the items.

So we want to use front end estimation to add;

325 + 53 + 33 + 71

Thus; 325 becomes 300, 53 becomes 50, 33 becomes 30

while 71 becomes 70

So the estimated total will be;

300 + 50 + 30 + 70 = 450

Now , since he saves $50 per month, the number of months it will take = 450/50 = 9 months

Given:

The graph of [tex]y = ax^2+c[/tex] contains the point (2, 14).

To find:

The point which lies on the graph of [tex]y = a(x-2)^2+c[/tex].

Solution:

Consider the given equations are

[tex]y_1 = ax^2+c[/tex]     ...(i)

[tex]y_2 = a(x-2)^2+c[/tex]      ...(ii)

The translation is defined as

[tex]g(x)=f(x+a)[/tex]

where, a is horizontal shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

From equation (i) and (ii), it is clear that a=-2. So, graph of [tex]y = ax^2+c[/tex] shifts 2 units right to get the graph of [tex]y = a(x-2)^2+c[/tex].

It means each point on [tex]y = ax^2+c[/tex] shifts 2 units right.

[tex](x,y)\to (x+2,y)[/tex]

(2, 14) lies on [tex]y = ax^2+c[/tex].

[tex](2,14)\to (2+2,14)[/tex]

[tex](2,14)\to (4,14)[/tex]

Therefore, (4,14)  must be lies on [tex]y = a(x-2)^2+c[/tex].
