Answer:

B. 3

Step-by-step explanation:

First of all we will define rotational symmetry.

Rotational symmetry is when a shape looks the same after some rotation or less than one rotation.

The order of rotational symmetry is how many times it matches the original shape during the rotation.

So, for the given shape the rotated shape will match the original shape three times so the order for symmetry for the given shape is 3.

Hence,

the correct answer is B. 3 ..

hope this works!!!!

To divide (10m⁸ + 4m⁶ + 10m⁵) by 2m², simplify each term by subtracting 2 from the exponents. The result is 5m⁶ + 2m⁴ + 5m³. The correct answer is D).

To divide (10m⁸ + 4m⁶ + 10m⁵) by 2m², follow these steps

Write the given expression: (10m⁸ + 4m⁶ + 10m⁵) / 2m².

Divide each term in the numerator by 2m² separately:

(10m⁸ / 2m²) + (4m⁶ / 2m²) + (10m⁵ / 2m²).

Simplify each term:

5m⁶ + 2m⁴ + 5m³.

The final result is 5m⁶ + 2m⁴ + 5m³.

The correct option is D).

In this division, we use the rule of exponents: when dividing terms with the same base, subtract the exponents.

The division by 2m² reduces the power of 'm' in each term by 2. So, 10m⁸ becomes 10m⁶, 4m⁶ becomes 2m⁴, and 10m⁵ becomes 5m³. The constants 10 and 4 remain unchanged. The simplified expression is the final result.

Answer:

60 different votes.

Step-by-step explanation:

This is a permutations question. There are a total of 5 bands to be voted for, and Rafeal has to vote only for 3 of the bands. It is also mentioned that the voting has to be done for the favorite, the second favorite, and the third favorite bands from the list. This means that the order of selection is important. This means that permutations will be used. Thus, 3 bands out of 5 have to be selected in an order. This implies:

5P3 = 5*4*3 = 60 possibilities.

There are 60 different votes!!!

Answer: 60 different votes are possible

Step-by-step explanation:

We have a list of 5 bands and we must choose 3 of them. In this case, the order of the election is important. Therefore this is a problem that is solved using permutations.

The formula for permutations is:

[tex]nPr=\frac{n!}{(n-r)!}[/tex]

Where n is the number of bands you can choose and you choose 3 of them.

Then we calculate:

[tex]5P3 =\frac{5!}{(5-3)!}\\\\5P3=\frac{5!}{2!}\\\\5P3 = 60[/tex]

Finally, the number of possible votes is 60

Answer:

C. y = x2 + 8x + 12

Step-by-step explanation:

To find x intercept/zero, substitute y = 0

0 = x^2 + 8x + 12

x^2 += 8x + 12 = 0

x^2 + 8x + 12 = 0

Solve the quadratic equation

x = -8±[tex]\sqrt{8^2 -4(12)[/tex] / 2(1)

any expression multiplied by 1 remains the same

x= -8±[tex]\sqrt{8^2 - 4(12)[/tex] / 2(1)

Evaluate the power

8^2

write the exponentiation as a multiplication

8(8)

multiply the numbers

64

x = -8±[tex]\sqrt{64 - 4(12)[/tex] / 2(1)

multiply the numbers

x = -8±[tex]\sqrt{64 - 48[/tex] / 2(1)

any expression multiplied by q remains the same

x = -8±[tex]\sqrt{64-48[/tex] /2

subtract the numbers

x = -8±[tex]\sqrt{16[/tex] / 2

calculate the square root

x= -8± 4 / 2

x= -8 + 4 / 2

x= -8 - 4 / 2

simplify the expression

x = -2

x = -8 - 4 / 2

x = -2

x = -6

final solutions are

x1 = -6, x 2 = -2

Answer:

So [tex]\frac{x^2-12x+8}{x-5}=(x-7)+\frac{-27}{x-5}[/tex]

Step-by-step explanation:

Since we are dividing by a linear factor, I'm going to use synthetic division.

Since the linear factor that we are dividing by is (x-5), I'm going to put 5 on the outside:

5    |     1       -12       8

      |              5      -35

      |--------------------------

           1         -7      -27

So the quotient x-7 while the remainder is -27.

So [tex]\frac{x^2-12x+8}{x-5}=(x-7)+\frac{-27}{x-5}[/tex]

You could do long division if you prefer:

           x-7

         ------------------------

(x-5) |   x^2-12x+8

        - (x^2-5x)

        --------------------------

                -7x+8

              -(-7x+35)

         ---------------------

                     -27

You still get the same thing that the quotient is x-7 and the remainder is -27.

Volume= 82.4in³

Step-by-step explanation:

Volume is the measure of the amount of space inside of a solid figure, like a cube, ball, cylinder or pyramid. It's units are always "cubic"

To find the volume of sphere, we will use the following formula of Volume:

Volume = 4/3 πr³

Put the values in the formula:

As we know that the value of π is 22/7 or 3.14

Radius = 2.7

According to the formula:

Volume = 4/3 * 3.14 *(2.7)³

Volume= 4/3* 3.14(19.683)

Volume=4/3(61.80462)

Volume=247.21848/3

Your question asks how much money was collected at the toll for a period of 8 hours.

To find the answer, we would need to gather some important information from the question.

Important information:

With the information above, we can solve the problem.

First, let's find how much money the toll makes in one hour. To find this, we need to multiply 1.50 by 160 cars, since the toll costs $1.50 and 160 cars go through it per hour.

[tex]1.50*160=240[/tex]

The toll makes $240 per hour.

Now, since we need to find how much the toll makes in 8 hours, we need to multiply 240 by 8.

[tex]240 * 8=1,920[/tex]

When you're done solving, you should get 1,920.

This means that the toll makes $1,920 in 8 hours.

Answer:

Given that the function is a model of miles per hour with x being representative of time in seconds, you simply have to plug 2 into the equation for each x.

Therefore,

g(x) = x^4 - 4x^2 + 7x - 8

becomes

g(x) = 16 - 16 + 14 - 8 = 6 miles per hour.

So, 6 mph is your answer!!

At rate of 6 miles per hour the rollercoaster travelling at 2 seconds.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

g(x) = [tex]x^4[/tex] - 4x² + 7x - 8

where x is time measured in seconds.

Now, the speed of roller-coaster for t= 2 seconds

g(2) =  [tex]x^4[/tex] - 4x² + 7x - 8

g(2) =  [tex]2^4[/tex] - 4(2)² + 7(2) - 8

g(2)= 16 - 16 + 14 - 8

g(2) = 6 miles per hour.

Hence, the speed 6 miles per hour.

Answer:

A. 14 meters

B. 24 meters

Step-by-step explanation:

A. Mellisa starts at 29 meters deep, then rises 15 meters.  So her final depth is 29 − 15 = 14 meters.

B. Melissa starts at 40 meters deep, then rises 2 m/min for 8 minutes.  That means she rises a total distance of 2 × 8 = 16 meters.  So her final depth is 40 − 16 = 24 meters.

Answer:

At one point, Mellisa is 29 meters below the surface of the water.

A.

As she swims around for the fish, she swims for 12 mins and rises upward by 15 meters.

So, her final depth at the end of the 12 minutes = [tex]29-15=14[/tex] meters

the number of $10 bills = 17

the number of $20 bills = 37

Step-by-step explanation:

Let x be the number of $10 bills  and y be the number of $20 bills

Total bills = 54

So [tex]x+y= 54[/tex]

Total value of money is $910

[tex]10x+20y= 910[/tex]

now we solve for x  and y

Solve the first equation for y

[tex]x+y= 54[/tex]

[tex]y=54-x[/tex]

Now replace y in second equation

[tex]10x+20y= 910[/tex]

[tex]10x+20(54-x)= 910[/tex]

[tex]10x+ 1080-20x= 910[/tex]

[tex]1080-10x= 910[/tex]

Subtract 1080 from both sides

[tex]-10x= -170[/tex]

Divide both sides by -10

x= 17

[tex]y=54-x[/tex]

Replace x with 17

[tex]y=54-17=37[/tex]

the number of $10 bills = 17

the number of $20 bills = 37

Step-by-step explanation:

The perimeter means the sum of all the sides of a figure.

The perimeter of a triangle would be sum of all 3 sides (triangle has 3 sides).

The measure oof 3 sides are given, so we just need to add them to get the perimeter.

Perimeter = 16.3 + 18.75 + 24.2 = 59.25 cm

To find the perimeter of the triangle, add the side lengths of 16.3 cm, 18.75 cm, and 24.2 cm to get a total of 59.25 cm. The formula used is simple addition of all side lengths.

To find the perimeter of a triangle, you need to add up the lengths of all its sides. The side lengths given are 16.3 cm, 18.75 cm, and 24.2 cm.

Therefore, the perimeter of the triangle is 59.25 cm.

On this line, for all y-values, the x-value will always be -3.

Since it is a vertical line it has no run, only a rise. This makes the slope undefined.

This said, the equation for this line is x = -3

Answer:

Susanne is 16 years old.

Step-by-step explanation:

You're gonna need three equations.

Key: B = Bob, D = Dakota, s = Susanne

B = 4s

D = s - 3

B + D + s = 93

Now plug in B and D into the third equation:

4s + (s - 3) + s = 93

Now solve it:

4s + s - 3 + s = 93

6s - 3 = 93

+3 +3

6s = 96

6s/6 = 96/6

s = 16

Bob's age is 4 times greater than Susanne's age, and Dakota is 3 years younger than Susanne.

The sum of their ages is 93. Susanne's age is 16.5.

Let's assign variables to represent the ages of the individuals involved:

We are given that Bob's age is 4 times greater than Susanne's age, so we can write the equation B = 4S.

We are also told that Dakota is three years younger than Susanne, so we can write the equation D = S - 3.

The sum of their ages is given as 93, so we can write the equation B + S + D = 93.

Substituting the first equation into the second equation, we get D = 4S - 3.

Substituting the values from the second and third equations into the fourth equation, we have (4S - 3) + S + (S - 3) = 93.

Simplifying this equation, we get 6S - 6 = 93. Adding 6 to both sides, we have 6S = 99. Dividing both sides by 6, we find that S = 16.5.

Therefore, Susanne's age is 16.5.

Step-by-step explanation:

Let the base of the board is x feet away from the wall .

And the hypotenuse, which is represented by the length of the board be 15 foot .

So here we have adjacent represented by the base and the hypotenuse .

And cosine function relates adjacent and hypotenuse , which is cos 60=15/x

And the value of cos 60 is half .

Performing cross multiplication

1/2=15/x

Dividing both sides by 2

x=7.5ft

Answer:

7.5 feet.

Step-by-step explanation:

The boardgame resting against the wall is creating a triangle rectangle and as it is forming a 60º angle with the ground that would be solve with the cosine of 60, which is the value of the division of the hypotenuse by the adjacent side, which would be the distance from the base of the board game to the wall:

Cos60= .5

cos60=adjacent side/hypotenuse

.5= adjacent side/15

adjacent side= 15x.5

Adjacent side=7.5 feet

Answer:

The vertex is (-2,-17).

Step-by-step explanation:

We have given y=2x²+8x-9

To find the x-coordinates we use:

xv= -b/2a

where a=2 and b=8

Now put the values in the formula:

xv= -(8)/2(2)

xv=-8/4

xv= -2

Now to find the y coordinates, we will simply substitute the value in the given equation:

y=2x²+8x-9

y=2(-2)²+8(-2)-9

y=2(4)-16-9

y=8-16-9

y=-8-9

y= -17

Therefore the vertex is(-2, -17)....

Step-by-step explanation:

5x + 2 = 3x + 4(2x - 1)

Distribute the 4

5x + 2 = 3x + 8x - 4

Combine like terms

5x + 2 = 11x - 4

Subtract 5x from each side

5x -5x + 2 = 11x - 5x - 4

2 = 6x-4

Add 4 to each side

2+4 = 6x-4+4

6 = 6x

Divide each side by 6

6/6 =6x/6

1= x

The value of x is 1 for equation 5x + 2 = 3x + 4(2x - 1).

A statement that affirms the equivalence of two expressions joined by the equals symbol "=" is known as an equation.

Given,

[tex]5x+2=3x+4(2x-1)\\[/tex]

[tex]5x+2=3x+8x-4[/tex]

On transposing like terms on one side of the equation.

[tex]5x-3x-8x=-4-2\\-6x=-6[/tex]

On multiplying -1 on both sides,

[tex]-6x\times(-1)=-6(-1)\\6x=6[/tex]

On dividing by 6 on both sides,
