The volume of the prism with given dimensions in the figure is equal to 612√3 cubic millimeter.

The dimensions of the triangular prism are,

Base of the triangle  'B' = 12mm

let us consider 'h' be the height of the triangle base.

Which intersect base at midpoint

height of the triangle 'h' = √ 12² - 6²

                                        = √108

                                        = 6√3mm

Side length of the prism 'l' = 17mm

Volume of the triangular prism

= ( 1/2 ) × Base × height × length of the side

= ( 1/2 ) × B × h × l

Now , substitute the values we have,

⇒ Volume of the triangular prism  = (1/2) × 12 × 17 × 6√3

⇒ Volume of the triangular prism  = 612√3 cubic millimeter.

Therefore, the volume of the triangular prism is equal to 612√3 cubic millimeter.

The maximum height achieved by the rider is given by the equation above. You can calculate this value using the given measurements and plug them into the equation to find the maximum height.

What is statistics?

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data. It involves the use of methods and techniques to gather, summarize, and draw conclusions from data.

A. The two quantities you would measure for x and y are the time and height, respectively.

B. The equation that relates time and height for an object in projectile motion is given by:

y = y0 + v0y * t - (1/2) * g * t²

where:

y = vertical height at any time t

y0 = initial vertical height (in this case, the height of the ramp)

v0y = initial vertical velocity (in this case, the vertical velocity of the rider at the top of the ramp)

g = acceleration due to gravity (approx. 9.81 m/s²)

t = time elapsed since the rider left the ramp

To apply this equation to the given image, you can put the picture on a grid with the x-axis representing time and the y-axis representing height.

C. To find the maximum height, you need to determine the point at which the rider's height is greatest. From the plotted points, you can see that the maximum height occurs at the point where the curve reaches its apex. You can find this point by calculating the time at which the vertical velocity of the rider becomes zero (i.e., the highest point of the jump). This occurs at the peak of the curve, where the vertical velocity changes from positive to negative. To calculate this time, you can use the equation for vertical velocity in projectile motion:

v = v0y - g * t

where:

v = vertical velocity at any time t

v0y = initial vertical velocity (in this case, the vertical velocity of the rider at the top of the ramp)

g = acceleration due to gravity (approx. 9.81 m/s²)

t = time elapsed since the rider left the ramp

At the peak of the jump, the vertical velocity becomes zero, so we can set v = 0 and solve for t:

0 = v0y - g * t

t = v0y / g

Substituting this value of t into the equation for height, we can find the maximum height:

y = y0 + v0y * (v0y / g) - (1/2) * g * (v0y / g)²

y = y0 + (v0y² / 2g)

Therefore, the maximum height achieved by the rider is given by the equation above. You can calculate this value using the given measurements and plug them into the equation to find the maximum height.

What is statistics?

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data. It involves the use of methods and techniques to gather, summarize, and draw conclusions from data.

To find the highest point the rider achieved on a jump, we need to measure the rider's height at different points during the jump.

A. The two quantities we would measure for x and y would be:

x: the horizontal distance the rider travels during the jump

y: the vertical height of the rider at different points during the jump

B. The equation that describes the rider's motion during the jump would be a quadratic equation in the form of:

y = ax² + bx + c

Where:

a is the coefficient of the quadratic term and represents the acceleration due to gravity

b is the coefficient of the linear term and represents the initial velocity of the rider

c is the constant term and represents the initial height of the rider

C. To find the maximum height, we need to find the vertex of the parabola that represents the rider's motion.

The vertex is the highest point on the parabola and is located at the point (-b/2a, c - b²/4a).

To find the vertex, we need to measure the rider's height at least two different points during the jump.

The two points should be on either side of the vertex to ensure that we have captured the shape of the parabola correctly.

hence, Once we have measured the rider's height at these two points, we can plug the values into the equation and solve for the vertex. Once we have found the vertex, we can determine the maximum height achieved by the rider.

The function has a minimum value of -2 that occurrs at x = -1

Given that

g(x) = 2x^2 + 4x

This is a quadratic function with a positive leading coefficient (2), which means that it opens upward and so it has a minimum value.

We can find the vertex of the parabola (the point where it changes direction) by using the formula:

x = -b/2a

where a and b are the coefficients of the quadratic function.

In this case, a = 2 and b = 4, so:

x = -4/(2*2) = -1

To find the corresponding y-value (the minimum value of the function), we substitute x = -1 into the function:

g(-1) = 2(-1)^2 + 4(-1) = -2

Therefore, the minimum of the parabola is at the point (-1, -2).

The small two above the radical symbol indicates that the square root of a mathematical number or expression is being taken, which means that the number under the radical must be squared to obtain the original number

Therefore,the correct answer is True.

An expression is a mathematical phrase that combines numbers, variables, and operations to create a value. It can include arithmetic, algebraic, or trigonometric operations and may contain parentheses, exponents, or radicals.

The square root of a number is a value that, when multiplied by itself, gives the original number. It is denoted by the symbol √ and is a type of radical.

According to the given information:

The correct answer is True.

The radical symbol, which looks like a division bar with a dot on top, is used to denote a root operation in mathematics. The index or degree of the root indicates the number of times the root must be multiplied by itself to obtain the number under the radical. In the case of the square root, the index is 2, which means that the number under the radical must be squared to obtain the original number.

Therefore, when the radical symbol has a small two above it, it is indicating that the square root of the number or expression below the radical is being calculated. The result of the square root operation is always a positive number, since the negative sign is indicated separately outside the radical symbol.

For example, the square root of 25 is written as √25 = 5, since 5 squared is equal to 25. Similarly, the square root of 4 is written as √4 = 2, since 2 squared is equal to 4.

In summary, the small two above the radical symbol indicates that the square root of a mathematical number or expression is being taken, which means that the number under the radical must be squared to obtain the original number.

Friday's practice session was 3 and 153/896 hours longer than

To find out how much longer Friday's practice session was than Wednesday's, we need to subtract Wednesday's practice time from Friday's practice time.

Friday's practice time is 2 3/7 hours. To make it easier to subtract, we can convert this mixed number to an improper fraction:

2 3/7 = (2 × 7 + 3) / 7 = 17/7

Now we can add this to Wednesday's practice time, which is already in improper fraction form:

1 1/8 = (1 × 8 + 1) / 8 = 9/8

Adding these two fractions, we get:

17/7 + 9/8

To add these fractions, we need to find a common denominator. The smallest number that both 7 and 8 divide into is 56, so we can convert both fractions to have 56 as the denominator:

17/7 × 8/8 = 136/56

9/8 × 7/7 = 63/56

Now we can add the numerators:

136/56 + 63/56 = 199/56

This is the total practice time for both Wednesday and Friday. To find out how much longer Friday's practice session was than Wednesday's, we need to subtract Wednesday's practice time from this total:

199/56 - 9/8

To subtract fractions, we need to find a common denominator again:

199/56 - 9/8 = (199/56) × (8/8) - (9/8) × (7/7) = 1425/448 - 63/56

Now we can subtract the numerators:

1425/448 - 63/56 = 2841/896

This is the difference between Friday's practice time and Wednesday's practice time, expressed as an improper fraction. To convert this back to a mixed number, we can divide the numerator by the denominator:

2841 ÷ 896 = 3 with a remainder of 153

So the answer is Friday's practice session was 3 and 153/896 hours longer than Wednesday's practice session.

Step-by-step explanation:

First, let's count the number of colored squares in the hundredth-grid.

There are a total of 42 hundredth-squares.

Since this is measured in hundredths, the number it represents is 0.42.

Each of the different colors represents a separate group that 0.42 is being divided into. There are 7 separate groups.

(- 2, 16 )

Step-by-step explanation:

y = 8x + 32 → (1)

y = - 8x → (2)

substitute y = 8x + 32 into (2)

8x + 32 = - 8x ( add 8x to both sides )

16x + 32 = 0 ( subtract 32 from both sides )

16x = - 32 ( divide both sides by 16 )

x = - 2

substitute x = - 2 into either of the 2 equations and evaluate for y

substituting into (2)

y = - 8(- 2) = 16

solution is (- 2, 16 )

If man travels "3-miles", turns left ,travel "6-miles", then turn left again travels "8-miles", then he is "7.8-miles" away from the starting point, No option is correct.

The man travel 3 miles straight, so we let the "starting-point" be (0,0),

So, the point after travelling 3 miles straight will be (0,3),

Next, he turns left and travels 6 miles(now facing downwards),

So, the coordinate becomes (6,3);

Next, he Turns left again(now facing right) and travels "8 miles" to the right .

So, the final-coordinate becomes (6, -5).

Now, we calculate the distance between the final point (6, -5) and the starting point (0,0) using the distance formula, which is the square root of the sum of squares of differences in "x" and "y" coordinates:

So, Distance = √((6-0)² + (-5-0)²),

Answer: 3.45meters

Step-by-step explanation:

To find the range of the length of pipe that the plumber can cut, we need to write an absolute value inequality that expresses the condition that the length of the pipe must be within 0.09 meters of the required length. Let's call the required length L.

The plumber can cut a pipe that is within 0.09 meters of the required length, so the length of the pipe must be between L - 0.09 and L + 0.09. We can express this as:

|3.36 - L| ≤ 0.09

To solve this inequality, we need to consider two cases: when 3.36 - L is positive and when it is negative.

Case 1: 3.36 - L ≥ 0

In this case, the absolute value of 3.36 - L is equal to 3.36 - L. So we can write:

3.36 - L ≤ 0.09

Solving for L, we get:

L ≥ 3.36 - 0.09

L ≥ 3.27

Therefore, if 3.36 - L is positive, the length of the pipe must be greater than or equal to 3.27 meters.

Case 2: 3.36 - L < 0

In this case, the absolute value of 3.36 - L is equal to -(3.36 - L), or L - 3.36. So we can write:

L - 3.36 ≤ 0.09

Solving for L, we get:

L ≤ 3.36 + 0.09

L ≤ 3.45

Therefore, if 3.36 - L is negative, the length of the pipe must be less than or equal to 3.45 meters.

Putting these two cases together, we get:

3.27 ≤ L ≤ 3.45

Therefore, the range of the length of pipe that the plumber can cut is between 3.27 meters and 3.45 meters.

x + 254.50 ≥ 500

Solving for x, we get:

x ≥ 500 - 254.50

x ≥ 245.50

Answer:

D

Step-by-step explanation:

given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

then the x- coordinate of the turning point ( vertex ) is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

y = 2x² + 4x - 3 ← is in standard form

with a = 2, b = 4 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{4}{2(2)}[/tex] = - [tex]\frac{4}{4}[/tex] = - 1

substitute x = - 1 into the equation for corresponding y- coordinate

y = 2(- 1)² + 4(- 1) - 3 = 2(1) - 4 - 3 = 2 - 7 = - 5

turning point = (- 1, - 5 )

Answer:

The Correct answer is D

(-1,-5)
