The ride that has the greatest elevation based on the information is B. Lightning bolt : 327 feet.

The term elevation is typically used to describe locations on the surface of the Earth, whereas altitude or geopotential height is used to describe locations above the surface, such as those of flying airplanes or orbiting satellites, and depth is used to describe locations below the surface.

Elevations show how your house will appear from various perspectives. Regarding these particular angles, there are many elevation kinds. Some varieties include split elevations, rear elevations, side elevations, and front elevations.

From the information, it was stated that the lightning bolt starts at an elevation of 15ft from the platform and speeds the passengers to an elevation of 327 ft.

It should be noted that the information is to simply find the elevation that is the greatest.

Based on the figures given, the appropriate elevation will be 327 feet.

Therefore, the correct option is B.

Answer:

No solution

Step-by-step explanation:

The sides of the equation are unbalanced, therefore, the equation has no solution. Here's an example(The problem is not designed to mathematically make sense).

[tex]x + 1 = -y \times z\\(w)x+1-1=-y+(z)x-1\\0 = -b[/tex]

Since the first side which was equal to 0 is unbalanced to the other side, the rule is that [tex]a = \mathrm{false\:if}\:a < 0[/tex], and since this rule applies in such a scenario, the equation ends up having no solutions.

Hope this helps!

If two trains going in opposite directions leave at the same time and train b travels 10 mph faster than train a and in 7 hours the trains are 630 miles apart, then the speed of the faster and slower train is equal to 50mph and 40mph respectively.

The speed of each train can be determined by using an algebraic

expression.

As one train travels 10 miles per hour faster than the other, consider x to be the speed of the slower train. In this case, the algebraic expression to find the speeds of each train can be given as,

7x + 7(x + 10) = 630

7x + 7x + 70 = 630

14x = 630 - 70

14x = 560

x = 560 ÷ 14

x = 40 mph

Therefore, x + 10 = 40 mph + 10 mph = 50 mph

Hence, the speed of the faster train is 50 mph and the speed of the slower train is 40mph.

When two functions are combined so the range of one becomes the domain of the other, the resulting function is called a Composite Function .

Composite Function : If f ( x ) is a function with domain x and f ( x ) = y is its range , then g [ f ( x ) ] is a composite function , where f ( x ) is the domain  and g [ f ( x ) ] = z is the range of function g [ f ( x ) ] .

Hence , when two functions are combined so the range of one becomes the domain of the other, the resulting function is called a composite function .

We can use the distance equation to help us solve this question:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Plug in the given points:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(8-(-4))^2+(-7-(-2))^2}\\d=\sqrt{(8+4)^2+(-7+2)^2}\\d=\sqrt{(12)^2+(-5)^2}\\d=\sqrt{144+25}\\d=\sqrt{169}\\d=13[/tex]

The length of line segment BC is 13 units.

Using the distance formula, the length of BC is: 13 units.

Given that:

B(8, -7) = (x1, y1)

C(-4,-2) = (x2, y2)

The distance formula that would be used to find BC is, d =[tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Thus, applying the distance formula, we have:

BC = √[(−4 − 8)² + (−2 − (−7))²]

BC = √[(−12)² + (5)²]

BC = √(144 + 25)

BC = √169

BC = 13 units

Therefore, using the distance formula, the length of BC is: 13 units.

The function is equal to zero when x = -3 or +4

We know that a function is a mathematical rule. It is an instruction to perform an operation on a given set of values. In this case, we have the function given as; f(x)= x^2-x-12/x^2+x-12. Recall that the function is equal to zero when the numerator is equal to zero.

Now we have to solve the quadratic equation;

x^2-x-12 =0

x^2 - 4x + 3x - 12 = 0

x(x - 4) + 3(x - 4) = 0

(x - 3) (x - 4) =0

x = -3 or +4

We can now see that the function is equal to zero when x = -3 or +4

Hunter kicked a soccer ball

It went 33/2 yards in 3/8 seconds

The distance it will travel in 1 second can be calculated as follows

33/2 = 3/8

x= 1

Cross multiply both sides

3/8x = 33/2

x= 33/2 ÷ 3/8

x= 33/2 × 8/3

The perimeter of the whole figure includes the sum of the side lengths and the value is -2 - 4m units

The area of a shape is the amount of space on the shape.

For most regular shapes, the area is the product of their width and the length

The area of this rectangle is given as

Area = 3m - 7m - 6

Evaluate the like terms

So, we have

Area = -4m - 6

The common factor of 4 and 6 is 2

So, we have the following equation

Area = 2(-2m - 3)

The area of the rectangle is

Area = Length * Width

So, we have

Length, L = 2

Width, W = -2m - 3

The perimeter of the rectangle is calculated as

P = 2 x (L + W)

So, we have

P = 2 x (2 - 2m - 3)

Evaluate the like terms in the above expression

So, we have

P = 2 x (-1 - 2m)

The inequality that is represented by the given graph is; y > 2x + 1

From the given graph, we have the following points coordinates;

(x1, y1) = (2, 5)

(x2, y2) = (6, 13)

The formula to calculate the slope is;

m = (y2 - y1)/(x2 - x1)

Thus;

m = (13 - 5)/(6 - 2)

m = 8/4

m = 2

On the graph, we have the following observations:

The line of the graph is a dashed line (this represents > or <)

Answer:

You would need to score a 10.

The equation is going to have a total of 5 values where one is unknown. We will call this unknown x and include it as a value in the equation.

Since we are going to have to find an average, we will need a fraction. We also know we will take five total tests. This will equal 12 as this is the desired average.

To start, create the fraction that will add all five values together and divide that by the number of values.

[tex]\displaystyle \frac{12+14+11+13+x}{5}[/tex]

Then, set this equal to 12.

[tex]\displaystyle \frac{12+14+11+13+x}{5}=12[/tex]

To solve, we will first combine all like terms.

[tex]\displaystyle \frac{50+x}{5}=12[/tex]

Then, divide the fraction.

[tex]\displaystyle 10+\frac{x}{5}=12[/tex]

Now, move the constants to the right side of the equation. To do this, subtract 10 from 12.

[tex]\displaystyle \frac{x}{5}=2[/tex]

Finally, multiply both sides of the equation by 5 to get rid of the denominator.

[tex]x=10[/tex]

Therefore, on test 5, you must score a 10 to maintain an average of 12.
