Answer:

39 deg

Step-by-step explanation:

The measure of an exterior angle is equal to half the difference of the measure of intercepted arcs.

(114-36)/2 = 39 deg

Answer:

b) the coefficient of x of jamie's polynomial is 5 .

c) The two polynomials are :

x³ + 4x² + 5x + 4 

x³ - 2x² + 5x + 4

Step-by-step explanation:

consider these two Monic polynomials of degree 3:

P : x³ + ax² + bx² + c  

Q : x³ + a₁x² + bx² + c  

P × Q = x⁶+ (a+a₁)x⁵ + (aa₁+2b)x⁴ + (ab+a₁b+2c)x³ + (ac+a₁c+b²)x² +2bcx + c²

Now we compare the coefficients of P × Q and  x⁶ + 2x⁵ +2x⁴ + 18x³ + 33x² + 40x + 16

b)

c² = 16 ⇒ c = 4  (c is positive)

2bc = 40 ⇒ 8b = 40 ⇒ b = 5 then the coefficient of x of jamie's polynomial is 5 .

c)

In order to find a and a₁ we need to solve this system:

a+a₁ = 2                   a+a₁ = 2

                      ⇔

aa₁+2b = 2              aa₁ = -8

Solve the system and you’ll get :

a = 4 and a₁ = -2   or a = -2 and a₁ = 4

Let’s choose a = 4 and a₁ = -2 then

the two polynomials are respectively:

P : x³ + ax² + bx² + c  = x³ + 4x² + 5x + 4

Q : x³ + a₁x² + bx² + c  = x³ - 2x² + 5x + 4

Answer:

Reflection over x-axis

Horizontal shift right 1

Vertical shift up 6

Step-by-step explanation:

see image to see how to find this infor in the equation.

Horizontal changes are in close to the x, but opposite of what you might think. Minus shifts RIGHT and plus shifts LEFT.

Answer:

Your answer:

Step-by-step explanation:

[tex]f(x)=x^2 , g(x)=-(x-1)^2+6[/tex]

[tex]y=-a(x-h)^2+k[/tex]

For g(x) our (h,k) = (1,6)

h - translate right/left, our h = 1 is right 1.

h - translate up/dqwn, our k = 6 is up 6.

If a = positive - no reflect x-axis. If a = negative - reflect x-axis.

Answer:

Start at 2 1/2 plot that. Then go to 3 3/10 which is 3 right of the whole number 3 and plot it. Lastly, draw lines or bumps to represent going from 2 1/2 to 3 3/10.

Step-by-step explanation:

The Simplest way (This includes the graphing part but I advise you to use the addition steps first)

I always like to convert mixed numbers into decimals.

2 1/2 is 2.5 and 4/5 is 0.8.

2.5 + 0.8 = 3.3 which is 3 3/10

Graph:

2 1/2 should be in the middle of the whole numbers 2 and 3.

That is your starting point.

Now to add 4/5 which is 0.8 you could do 2.5 + 0.8 = 3.3

You need to find your ending point.

Your ending point should be 3 tickmarks to the right of 3.

Now, you could draw hop marks or arrows starting from 2 1/2 to 4/5

Addition Steps:

First, convert 2 1/2 to an improper fraction.

2x2 + 1 = numerator.

4+1 = 5

5/2 is 2 1/2.

Now you need to find a common denominator for 2 and 5.

This should be 10.

Multiply 5/2 by 5/5

Multiply 4/5 by 2/2

25/10 and 8/10 should be the answers

Now do 25+8 but keep the denominator 10.

25+8 is 33/10.

You could convert it to 3.3 which is 3 3/10  

3 3/10 is on your number line.

Answer:

Arc cd = 60 degrees

Step-by-step explanation:

Angle E is an inscribed angle ....inscribed angle will intercept twice as many degrees of arc as the angle measure

  angle measure = 62    twice as many degrees of arc = 124  (b-c-d)

     bc = 64    so   cd  = 60    for the total of 124

Question:

Can anyone help been stuck for a while

Answer:

[tex]\frac{5}{11}[/tex]

Step-by-step explanation:

30 regular flavors.

25 watermelon flavors.

Add them both and you get:
55.
Turn that into a fraction:

[tex]\frac{25}{55}[/tex]

The reason the numorator is 25 is because there are 25 watermelon flavors and 55 flavors total.

Find the GCD (or HCF) of numerator and denominator.

The GCD of 25 and 55 is 5.

Divide both the numerator and denominator by the GCD

25 ÷ 5 = 5

55 ÷ 5 = 11

Reduced fraction:

[tex]\frac{5}{11}[/tex]

Therefore, [tex]\frac{25}{55}[/tex] simplified to lowest terms is:

[tex]\frac{5}{11}[/tex]

Therefore, the answer is: [tex]\frac{5}{11} \\[/tex]

Answer:

Step-by-step explanation:

Use the distributive property.

Distributive property:

[tex]\sf{\dfrac{5}{6}=(12p-42) }[/tex]

Multiply by expand.

[tex]\Longrightarrow: \sf{\dfrac{5}{6}\cdot \:12p-\dfrac{5}{6}\cdot \:42}[/tex]

Solve.

5/6*12p=10p

5/6*42=36

Use the order of operations.

PEMDAS stands for:

[tex]\sf{\dfrac{5}{6}\cdot \dfrac{42}{1}=\dfrac{5*42}{6} }[/tex]

Divide.

42/6=7

Multiply.

5*7=35

Subtract.

35-35=0

[tex]\Longrightarrow: \boxed{\sf{10p-35}}[/tex]

Therefore, the correct answer is 10p-35.

I hope this helps. Let me know if you have any questions.

Answer:

[tex]10p - 35[/tex]

Step-by-step explanation:

Step 1:  Distribute

[tex]\frac{5}{6}(12p - 42)[/tex]

[tex](\frac{5}{6}*12p) + (\frac{5}{6} * (-42))[/tex]

[tex]\frac{60p}{6}-\frac{210}{6}[/tex]

Step 2:  Simplify the expression

[tex]\frac{60p}{6}-\frac{210}{6}[/tex]

Answer:

D. No solution

Step-by-step explanation:

Since, both the lines are going parallel to each other. Hence, there will be no solution.

The probability of drawing two red buttons is:

P = 0.0326

There are:

So there are a total of 32 + 48 + 44 + 51 = 175

We assume that all the buttons have the same probability to being randomly drawn.

For the first button, the probability of drawing a red one is equal to the quotient between the number of red buttons and the total number of buttons:

p = 32/175

For the second button the probability is computed in the same way, but now there are 31 red buttons and 174 buttons in total, so we have:

q = 31/174

Finally, the joint probability is given by the product between p and q, this gives:

p*q = (32/175)*(31/174) = 0.0326

Answer:

1. x=10; y=10 x root 2

Step-by-step explanation:

This is a 45-45-90 triangle, so the legs of the right triangle have an equal length. The formula states that y=x root 2, which is 10, so 10 root 2. The other triangles are all 30-60-90 triangles.
