Answer:

See below

Step-by-step explanation:

A simple method is to count the bumps or flex spots on the graph then add 1.

This will give you the smallest degree possible but the actual degree may be higher. When asked for the smallest, you don't have to worry what the actual might be. In addition, if you look at the ends of the lines, this can tell you if the degree is an odd or even number. If the start of the line is going in the opposite direction of the end, then it is odd. Each of these polynomials are odd since the start and end are in opposite directions.

93. Two bumps so the smallest degree is 3

94. No real bumps but there is a flex spot and the line changes direction twice. The line ends go in opposite directions so degree must be odd. So smallest degree is 3

95. This one could be tough. Flattened sections like the middle of this can have a smallest degree of 4 or more depending on how long it stays flat. There are two bumps so without the flattened section the degree is 3 so far. The degree must be odd since the lines trails off in opposite directions. Because of the flatness of the middle I would say that section is a degree 4 so I'm guessing the smallest degree is 7.

96. Two bumps so smallest degree is 3

A number is increased by 60 is equal to 410. Find the number

Doss [256]

Answer:

---------------- Heya KDAAS ! -----------------

SolutioN :

Let the number be ' x ' . Now , set up an equation and solve for x :

$\large{ \tt{ \star \: x + 60 = 410}}$

$\longrightarrow{ \tt{x = 410 - 60}}$

$\longrightarrow \tt \: x = \boxed{ \tt{350}}$

Our final answer : 350

Triangle XYZ is shown, where n ≥ 5. Triangle X Y Z is shown. The length of side X Y is n + 4, the length of side Y Z is 2 n, and

Answer:

The longest side of the triangle is YZ, the shortest side is ZX, the largest angle is ∠X and the smallest angle is ∠Y.

Step-by-step explanation:

The lengths of the sides of the triangle XYZ are as follows:

XY = n + 4

YZ = 2n

ZX = n - 2

According to the triangle inequality theorem, the sum of two sides of a triangle is always greater than the third side.

Then,

XY < YZ + ZX ⇒ n + 4 < 2n + n - 2 ⇒ n + 4 < 3n - 2 ⇒ 2n > 6 ⇒ n > 3

YZ < XY + ZX ⇒ 2n < n + 4 + n - 2 ⇒ 2n < 2n + 2 ⇒ 0 < 2

ZX < XY + YZ ⇒ n - 2 < n + 4 + 2n ⇒ n - 2 < 3n + 4 ⇒ 2n > -6 ⇒ n > -3

It is provided that <em>n</em> ≥ 5.

Then the sides of the triangle are:

XY = n + 4 ≥ 5 + 4 = 9

YZ = 2n ≥ 2 × 5 = 10

ZX = n - 2 ≥ 5 - 2 = 3

So, the longest side of the triangle is YZ. And the shortest side is ZX.

The largest angle of a triangle is opposite to the longest side.

The angle opposite to YZ would be X. So, the largest angle is ∠X.

The smallest angle of a triangle is opposite to the shortest side.

The angle opposite to ZX would be Y. So, the smallest angle is ∠Y.

Thus, the longest side of the triangle is YZ, the shortest side is ZX, the largest angle is ∠X and the smallest angle is ∠Y.
