The triangle NET is an isosceles triangle as ET ≅ TN and ET = TN < EN given the condition that BEST is a cyclic quadrilateral.

In this question we must apply geometric properties of angles and triangles to determine that the triangle NET is an isosceles triangle. Isosceles triangles are triangles with two sides of equal length. In addition, we must apply the geometric concept of proportionality.

Now we proceed to prove the existence of the isosceles triangle:

Therefore, the triangle NET is an isosceles triangle as ET ≅ TN and ET = TN < EN given the condition that BEST is a cyclic quadrilateral. [tex]\blacksquare[/tex]

Answer:

Points A and B are not on the unit circle.

Step-by-step explanation:

Recall that a "unit circle" has a radius of 1, and so if x² + y² ≠ 1, the point is not on a unit circle.

In A we apply the Pythagorean Theorem as follows:  1² + 1² = 2 ≠ 1.

Therefore, point (1, 1) is not a point on the unit circle.

In B:  if we square the x and y components and add these squares together, we get 3/4 + 1/9, which does not equal 1.  Point not on unit circle.

In C, we get 4/9 and 5/9, which eqals 1.  This point C lies on the unit circle.

In D, we get 0.64 + 0.36 = 1, so this point does lie on the unit circle.

Thus:  not on unit circle:  A(1, 1), B(√3/2, 1/3)

On unit circle:  D(0.8, -0.6), C(-2/3, √5/3)

The Brand Blast normally charges a shirt is $13 if the Blast reduced the price of each shirt by $5 principal Howard paid $928 in all.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

Let's suppose the normally Blast charge $x for each shirt

So according to the problem:

116(x-5) = 928

x = $13

Thus, the Brand Blast normally charges a shirt is $13 if the Blast reduced the price of each shirt by $5 principal Howard paid $928 in all.

Answer:

10/17

Step-by-step explanation:

Each card has two parts. A top part and bottom part. On the top parts of all the cards, there's a simple pattern of adding 2 to the previous number each time. On the bottoms of the cards, you have to add 3 to a number to get to the next number in line. Therefore, take the 4th card (8 on top 14 on bottom) and add a 2 to the top number and a 3 to the bottom number to get the next card in the pattern.

8   +   2   =   10  

---                 ---      

14  +  3   =    17

So card 5 is

10 / 17

Answer:

The answer is

→ C.) The graph starts flat but curves steeply upward.

Step-by-step explanation:

Explaining option C:

The quick leaps in y-coordinates indicate that it continues to travel higher up faster and faster while the x-coordinates proceed continuously.

The first choice is incorrect since the slope formula yields a value of 15 for the slope. The second choice is incorrect since it is impossible for it to be a horizontal line unless x = 0, which it is not because it equals 2. The last choice is incorrect because, rather of continuously increasing in size, a parabola function begins to decrease in size (the vertex would be visible in the function if this was a parabola.)

Therefore, Option C.) The graph starts flat but curves steeply upward is your answer.

Hope this helped! :^)

He make his Exchange on Friday.

The correct option is B.

A currency's relative value expressed in terms of another currency is called an exchange rate (or group of currencies). The exchange rate is a significant economic variable for nations with active international trade, like Australia.

In other words, the exchange rate is the cost of one currency relative to another.

We have,

Day                 $                 €

monday          1                0.7102

tuesday           1                0.7053

wednesday     1                0.6869

thursday          1                0.6910

friday               1                0.7273

saturday          1                0.7544

b friday

So, 228.7 / 314. 52

Equating the slopes

The time for the job for which the two company are the same is 16

A yard cleanup service charges a $345 fee plus $16.25 per hour. Therefore,

using linear equation,

y = mx + c

where

Therefore,

y = 345 + 16.25x

Another cleanup service charges a $213 fee plus $24.50 per hour. Therefore,

y = 213 + 24.50x

Hence, the time when both cost are the same is as follows;

213 + 24.50x =  345 + 16.25x

213 - 345 = 16.25x - 24.50x

-132 = -8.25x

x = 132 / 8.25

x = 16

Fraction are ratios of two integers. Given the following parameters

Total distance covered by Marianna = 1.2km

If Ian runs 25% further than Marianna, the total distance covered by lan is expressed as:

Total distance covered by Lan .= 1.25 * 1.2
Total distance covered by Lan = 1.5km

Hence Lans have covered 1.5km if he ran 25% further than Marianna.

The possible domain is:

The domain of the function is the set of possible values of d.

Because d represents the depth of water,

The starting value can take any value, less than 0

But the end value must be 0 (i.e. the surface of water)

This means that, the domain of the function will be from negative infinity to 0

Hence, the domain is (-infinity, 0}
