WHY is the number of roots less than or equal to the degree

Answers

Answer 1

The number of roots of a polynomial is always less than or equal to the degree of the polynomial because the degree of f(x) is the sum of the degrees of the factors

Why is the number of roots less than or equal to the degree?

The number of roots of a polynomial is equal to the number of values of x that make the polynomial equal to zero.

The degree of a polynomial is the highest exponent of the variable in the polynomial. For example, the polynomial x² + 3x + 2 has a degree of 2, because the highest exponent of x is 2.

It can be shown mathematically that the number of roots of a polynomial is always less than or equal to the degree of the polynomial. This is known as the Fundamental Theorem of Algebra.

Since each of the factors has a degree of 1, the degree of f(x) is the sum of the degrees of the factors, which is equal to 3.

Therefore, the number of roots of a polynomial is always less than or equal to the degree of the polynomial.

A man flies a kite and lets out 100 feet of string. The angle of elevation of the string is 52°. How far away is the man from the spot directly under the kite?

Answers

Answer:

61.57 ft

Step-by-step explanation:

Look at the picture. You need to find the base value.

so we can sue the cosine formula here.

cos x° = adjacent / hypotaneous

cos 52 ° = adj / 100

adjacent = 100 cos 52°

               =61.57 ft

Answer:

the man is 61.6 ft away from the spot directly under the kite.

Step-by-step explanation:

in order to find the bottom length which is b we need to First find the height of this right angle triangle.

to find the height we need to use sin:

sin 52° = X/100

sin 52° * 100 = h

h= 78.8 ft

next we can find b which is the base of the triangle.

a^2+b^2=c^2

100^2 +b^2 = 78.8^2

100^2 -78.8^2 = b^2

b^2= 3790.56

b= 3790.56

b= 61.6 ft

therefore the man is 61.6 ft away from the spot directly under the kite.

Find the circumference of the semi circle 7cm

Answers

Given:

A semicircle with radius 7 cm.

To find:

The circumference of the given semi circle.

Solution:

We know that,

Circumference of a semi circle = Half of circumference of the circle + Diameter

                                                    [tex]=\dfrac{1}{2}(2\pi r+d[/tex]

                                                    [tex]=\pi r+2r[/tex]

Putting [tex]\pi=\dfrac{22}{7},r=7[/tex], we get

Circumference of the semi circle [tex]=\dfrac{22}{7}(7)+2(7)[/tex]

                                                        [tex]=22+14[/tex]

                                                        [tex]=36[/tex]

Therefore, the circumference of the given semi circle 36 cm.

23. Three businessmen A, B and C enter into
partnership and agree to share the total
profit in the ratio of their investments. A
invested GH¢450, B invested GH¢150
and C invested GH¢600. C received a
profit of GH¢24.70, find
i) the total profit.
ii) the profits made by A and B.​

Answers

Step-by-step explanation:

A invested 450

B invested 150

C invested 600

total investment was 1200

share of A is 450/1200 = .375

share of B is 150/1200 = .125

share of C is 600/1200 = .5

C received a profit of 24.70.

that would be .5 of the total profit.

if we let x = total profit, we get .5 * x = 24.70

solve for x to get x = 24.70 / .5 = 49.40

A share of total profit = .375 * 49.4 = 18.525

B share of total profit = .125 * 49.4 = 6.175

C share of total profit .5 * 49.4 = 24.7

total profit = 49.4 as we had calculated earlier.

Susan estimated she would spend $250 on school clothes at the start of the school year. She actually ended up spending only $230. What was her percent of error in her calculations?

Answers

Answer:

8.70%

Step-by-step explanation:

Percentage error = (difference between estimated value and actual value / actual amount spent) x 100

difference between estimated value and actual value = estimated value - actual amount

$250 - $230 = $20

($20 / $230) x 100 = 8.6957%

D) 65

Step-by-step explanation:

Help please it’s due

Answers

Step-by-step explanation:

Since ABC is a triangle,

Angle A + Angle B + Angle C = 180 (Sum of angles in a triangle)

given Angle A = 3x + 1

Angle B = 4x - 17

Angle C = 5x - 20

[tex]3x + 1 + (4x - 17) + (5x - 20) = 180 \\ 3x + 4x + 5x + 1 - 17 - 20 = 180 \\ 12x - 36 = 180 \\ 12x = 180 + 36 \\ 12x = 216 \\ x = 216 \div 12 \\ = 18[/tex]

Now substitute x into all 3 angles.

A = 3(18) + 1 = 54 + 1 = 55 degrees

B = 4(18) - 17 = 72 - 17 = 55 degrees

C = 5(18) - 20 = 90 - 20 = 70 degrees

Since Angle A = Angle B but not equal to Angle C,

Triangle ABC is a isosceles triangle as 2 angles must be the same for it to be a isosceles triangle.

answer anybody?? i can't do math like at all lol

Answers

Essentially, what we're looking at here are two alternate interior angles.

Wait. What? Alternate interior angles?

It sounds like some super fancy math jargon, but it's a fairly simple concept that I'll try my best to explain. First, let's look at lines L and M as two parallel lines, meaning that these two are lines with equal slopes, and will never intersect. See that line that goes in between the parallel lines L and M? That's called a transversal. It's basically a line that goes through two parallel lines.

Now we know that there's a transversal going through the parallel lines. So what? Well, there's a couple of special attributes to transversals. See the two angles, 7x-7 and 4x+14? As you can tell, these two angles alternate in the interior space between the transversal and the parallel lines.

Alternate interior angles are equal. There's a way to prove that they're equal, but I won't bore you with the specifics since that's not what the question's asking.

If the angles need to be equal for lines L and M to be parallel, we can make an equation that'll solve for x:

7x - 7 = 4x + 14

Subtract 4x from both sides:

7x - 4 x - 7 = 4x - 4x + 14

3x - 7 = 14

Add 7 to both sides:

3x - 7 + 7 = 14 + 7

3x = 21

Divide both sides by 3 to completely isolate x:

[tex]\frac{3x}{3}[/tex] = [tex]\frac{21}{3}[/tex]

x = 7

And that's our answer! If you need me to explain anything any further, just ask!

write a statement that correctly describes the relationship between these two sequences: 2, 4, 6, 8, 10 and 1,2,3,4,5.

Answers

Answer:

The relationship between these two sequences is it always doubles.  When we look at each sequence, 1, 2, 3, 4, 5, each number is multiplied by 2 to create the other sequence.

1 x 2 = 2.

2 x 2 = 4.

3 x 2 = 6.

4 x 2 = 8.

5 x 2 = 10.

When we arrange these numbers, 2, 4, 6, 8, 10, this is the exact sequence as before.  Therefore, this is the relationship.

                                                          2 x 2 = 4                       |

                                                          2 x 3 = 6                       |

5x + 2y = 18
-5x + 5y = 45

Answers

Answer:

the answer for this problem is (x,y)=(0,9)

Answer:

y = 9

x = 0

Step-by-step explanation:

5x + 2y = 18

-5x + 5y = 45 add two equations up

5x + 2y -5x + 5y = 18 + 45 add like terms (note that, 5x will eliminate -5x)

7y = 63 divide both sides by 7

y = 9 to find the value of x we can use this information

5x + 2y = 18 replace y with 9

5x + 2*9 = 18

5x + 18 = 18 subtract 18 from both sides

5x = 0 and x = 0
