Answer:

The key graphical features obtained from a polynomial function are: the zeros, the turning points and the end behaviour. A "zero" of a polynomial function is an input value that produces an output of zero (0).

There are 3 methods to find the lowest common multiple (LCM)

---------------------------

Method 1

List out the multiples of 6 and 8

multiples of 6 = {6, 12, 18, 24, 30, 36, 42, 48, ...}

multiples of 8 = {8, 16, 24, 32, 40, 48, ...}

We see that 24 is the smallest number in both sets at the same time. So this is the LCM.

---------------------------

Method 2

Write the prime factorization of 6 and 8

prime factorization of 6 = 2*3

prime factorization of 8 = 2*2*2

The unique prime factors here are 2 and 3. We have 2 show up at most three times meaning that 2*2*2 = 8 is a factor of the LCM. The number 3 is also a factor meaning that 8*3 = 24 is the LCM.

---------------------------

Method 3

Multiply the denominators 6 and 8 to get 6*8 = 48

48 is a common multiple, but its not the smallest

we can divide 48 over the GCF 2 to get 48/2 = 24, which is the actual LCM.

So when you have 2 different denominators, you can multiply their values and then divide by the GCF to get the LCM.

Answer: B

Step-by-step explanation:

1. Multiplying two negatives equals a positive.

2. Reduce the numbers with the GCF, 3.

3. Reduce the numbers with the greatest common factor, 2.

4. Multiply the fractions which would give you: 5/6

Answer:

B. 5/6

Step-by-step explanation:

1.multiply -3 by -10 (negative multiplying negative is positive) which will give you 30

2.Then multiply 4 by 9 = 36.

3.u will get 30/36, divide both the numerator and denominator by 6.

4. it will give you 5/6 as an answer.

The Value of the equation is 19.

A linear equation is a type of equation in which every variable's degree is exactly one. In one-variable linear equations, there is only one possible solution to the equation and there is only one variable. It appears to be a straight line, either horizontally or vertically, when it is drawn on a graph.

Given equation 3m - 2

and m = 7

substitute the value of m in the equation,

3 x 7 - 2

21 - 2 = 19

Hence the value is 19.

Work Shown:

x = central angle = 255 degrees

r = radius = 4

A = area of sector

A = (x/360)*pi*r^2 ... see note below

A = (255/360)*pi*4^2

A = 34pi/3

note: the formula only works if the central angle x is in degrees. If x is in radians, then use the formula A = (x/2)*r^2

Answer:181/250

Step-by-step explanation:

Answer:

Option (A)

Step-by-step explanation:

It has been given in this question that sign telling path has a 2% grade.

2% grade means a rise of 2 meters for a horizontal change of 100 m (As given in the figure attached).

All the trigonometric ratios for the angle θ between the path and the horizontal are,

Sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

Cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

Since measures of the opposite side and adjacent sides are given

Therefore, tangent ratio will be applied to get the measure of the angle,

tanθ = [tex]\frac{2}{100}[/tex]

θ = [tex]\text{tan}^{-1}(\frac{2}{100})[/tex]

Option (A) will be the answer.

Step-by-step explanation:

Answer:

The length r can be found using the Law of sines.

Length r = 14.8

Step-by-step explanation:

The length r can be found using the Law of sines.

The formula for the Law of Sines states that:

a/Sin A = b/ Sin B

In the above question,

∠P = 27°

∠R = 135°

p = 9.5

r = ????

The formula =

p/Sin P = r/Sin R

9.5/Sin 27° = r/Sin 135°

Cross Multiply

r × Sin 27° = 9.5 × Sin 135°

r = 9.5 × Sin 135°/Sin 27°

r = 14.7966

Approximately Length r = 14.8

Answer:

90 dollars. The total will be $1,590.00.

Step-by-step explanation:

6% of 1500 is 90

We start by converting 6% to a fraction :

6% = 3/50  

Then we have

6% of 1500 = 3/50 x 1500 = 3/50 x 1500/1 = 4500/50

Notice that 1500 was rewritten as the fraction 1500/1, and that to multiply two fractions together, you simply multiply the numerators and denominators.

In order to find the simplest form of the fraction 4500/50 we cancel out the greatest common divisor of 4500 and 50, which is 50 :

4500/50=90/1

So the final answer is

6% of 1500=90

Answer:

102.5, 103.5

Step-by-step explanation:

a+a+1=206

2a+1=206

2a=205

a=102.5

103.5

I think there is a bug here. They can't be whole numbers.

Answer:

There are no two consecutive whole numbers that sum to 206 (See proof below)

Step-by-step explanation:

let the first number be x

since the numbers are whole and consecutive, the second number must be (x + 1)

we are given that the number sum to 206

hence,

x + (x+1) = 206

x + x + 1 = 206

2x + 1 = 206  (subtract 1 from both sides)

2x = 206 - 1

2x = 205  (divide both sides by 2)

x  = 205/2 = 102.5  (NOT A WHOLE NUMBER)

if x = 102.5, then the second number must be

x + 1 = 102.5 + 1 + 103.5 (ALSO NOT A WHOLE NUMBER)

Answer:

X intercept = (2,0)

Y intercept = (0,-3)

Step-by-step explanation:

To find x intercept make y into 0

3(x) - 2(0) =6

3x = 6

x = 2

X intercept = (2,0)

Y intercept do the same

Y intercept make x into 0

3(0) - 2(y) =6

-2y = 6

y = -3

Y intercept = (0,-3)

Answer:

x -intercept is at (2, 0).

y -intercept is at (0, -3).

Step-by-step explanation:

x intercept is found when y = 0:

3x - 2(0) = 6

3x = 6

x = 2.

x intercept is found when x = 0:

3(0) - 2y = 6

-2y = 6

y = -3.
