No , 23 x 10⁶ is not written in scientific notation.

Values that are either too huge or too little to be conveniently expressed in decimal form can be expressed using scientific notation (typically would result in a long string of digits).

So 23 x 10⁶ written in exact scientific notation is given by 2.3 × 10⁷ .

Therefore   2.3 × 10⁷ is written in scientific notation whereas  23 x 10⁶  is not in scientific notation.

Answer:

The total cost of the hotel room is $235.20

Step-by-step explanation:

Here, we want to find the total cost of the hotel room

Total cost of hotel room = Cost of hotel room for the two nights + tax

Tax = 12%

Total cost = 210 + 12% of 210

Total cost = 210 + (12/100 * 210)

Total cost = 210 + 25.2

Total cost = $235.2

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

Explanation:

First let's find BD

The three triangles are similar, allowing for the proportion to be set up

AD/BD = BD/DC

9/x = x/8

9*8 = x*x

x^2 = 72

x = sqrt(72)

BD = sqrt(72)

Now we can use the pythagorean theorem. Focus on triangle BDC.

The legs are BD = sqrt(72) and DC = 8. Let's find the hypotenuse

(BD)^2 + (DC)^2 = (BC)^2

(sqrt(72))^2 + (8)^2 = m^2

72 + 64 = m^2

136 = m^2

m^2 = 136

m = sqrt(136)

We can simplify this but your teacher has chosen not to. If you want to simplify, then,

m = sqrt(136)

m = sqrt(4*34)

m = sqrt(4)*sqrt(34)

m = 2*sqrt(34)

Answer:

Then isolate your variable, do this by dividing both sides by 3.

3y=30

3y/3=30/3

Finally, simplify

A perpendicular bisector is a line that crosses (bisects) another line segment at 90 degrees, dividing the line segment it crosses into two equal length lines

The additional information Kiran need to know to show that AB is a perpendicular bisector is the fourth option;

DB and BC are congruent

The reason for the above selection is as follows:

The information about the isosceles triangle DAC Kiran knows are;

Triangle DAC = An isosceles triangle

Segment AD is congruent to segment AC

Segment AB is a  is a line from the vertex point A to the side CD of triangle DAC

The required parameter:

The information Kiran has know so as to show that AB is a perpendicular bisector of CD

Method:

Determine an attribute present in triangle DAC with line AB drawn that is due to line AB being a perpendicular bisector

Solution:

For AB to be a perpendicular bisector, then DB and BC are congruent

Given that DB and BC are congruent, we get;

AB is congruent to AB by reflexive property

Therefore, given that AD is congruent to AC, we have;

Sides AD, AB, and DB in triangle ΔADB are congruent to the corresponding sides AC, BC, and AB in triangle ΔACB, which gives

ΔADB is congruent to ΔACB by Side-Side-Side, SSS, congruency rule

Therefore, ∠ABD ≅ ∠ABC, by Congruent Parts of Congruent Triangles are Congruent, CPCTC

∠ABD = ∠ABC by definition of congruency

∠ABD and ∠ABC are linear pair angles, therefore;

∠ABD + ∠ABC = 180°

∠ABD + ∠ABD = 2 × ∠ABD = 180° by substitution property

∠ABD = 180°/2 = 90°

∠ABD = 90° = ∠ABC, therefore, AB is perpendicular to CD and AB is a perpendicular bisector of CD

Therefore, the correct option Kiran need to know in order to show that AB is a perpendicular bisector of segment CD is the option; DB and BC are congruent

Answer:

The answer is below

Step-by-step explanation:

From the image of the leaning tower of Pisa, we can see that it passes through the point (7.75, 0) and (10.75, 42).

a) The equation of a line in slope intercept form is given by y = mx + b, where m is the slope and b is the intercept. Also, the equation of line passing through

[tex](x_1,y_1)\ and\ (x_2,y_2)\ is:\\\\y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]

Hence since it passes through  (7.75, 0) and (10.75, 42), the equation is:

[tex]y-0=\frac{42-0}{10.75-7.75} (x-7.75)\\\\y=14(x-7.75)\\\\y=14x-108.5[/tex]

b) When the tower is 56 meters tall, i.e. y = 56, we need to find the value of x:

y = 14x - 108.5

56 = 14x - 108.5

56 + 108.5 = 14x

164.5=14x

x = 164.5/14

x = 11.75

When the tower is 56 meters tall, the top of the tower is 11.75 m off center

Answer:

108°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

2a is an exterior angle, thus

2a = a + 10 + 44 = a + 54 ( subtract a from both sides )

a = 54

Thus 2a = 2 × 54 = 108° ← exterior angle
