The number 3 in the equation h(t) = -16t² + 6t+ 3 represents option 2 - the height from which the ball is thrown.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The equation h(t) = -16t² + 6t+ 3 gives the height of the ball as a function of time.

The constant term in this equation is 3, which represents the initial height of the ball when it is thrown.

Therefore, the correct answer is (2) the height from which the ball is thrown.

Option (1) cannot be correct, because the maximum height of the ball occurs when the derivative of h(t) is zero, which is not necessarily equal to the constant term in the equation.

Option (3) cannot be correct, because the ball reaches the ground when h(t) = 0, which requires solving a quadratic equation.

Option (4) cannot be correct, because the time it takes for the ball to reach its maximum height is given by the formula t = -b/2a, where a and b are the coefficients of the quadratic equation, and it does not depend on the constant term.

Therefore, option 2 is the correct answer.

We estimate that Jordan will drive a distance of approximately 4668.3 miles during the entire 7-day road trip.

Distance and displacement are two key words in mechanics that, although having similar sounds, have distinct definitions and meanings. How much of an object's path is covered by a moving object is measured in terms of distance. Whereas "How much route is covered by the item in a specific direction" is measured by displacement, The main distinction between distance and displacement is therefore that the former is a scalar quantity while the latter is a vector quantity.

Given that, the distance travelled is  666.9 miles.

The same distance is travelled for 7 days thus,

distance = Distance per day x Number of days

distance = 666.9 miles/day x 7 days

distance = 4668.3 miles

The relationship between the diameter of a circle and it's circumference is presented in this problem.

The circumference of a circle of radius r is given by the equation presented as follows:

[tex]C = 2\pi r[/tex]

The radius of a circle represents the distance between the center of the circle and a point on the circumference of the circle, while the diameter of the circle is the distance between two points on the circumference of the circle that pass through the center. Hence, the diameter’s length is twice the radius length.

The diameter is twice the radius, hence, for a circle with diameter 35 in, the radius is given as follows:

r = 0.5 x 35

r = 17.5 in.

Then the circumference of the circle is given as follows:

C = 2 x pi x 17.5

C = 109.9 in.

The problem is incomplete, hence the relation between the diameter of a circle and it's circumference is presented.

The side lengths of given triangle is;

a=5 units

b=18.72 units

c=18.99 units

A triangle is a closed, two-dimensional figure with three straight sides and three angles. It is one of the basic shapes in geometry and is formed when three non-collinear points are connected by straight lines. The sum of the interior angles of a triangle is always 180 degrees, and there are various types of triangles, including equilateral triangles (where all three sides are of equal length and all three angles are 60 degrees), isosceles triangles (where two sides are of equal length), and scalene triangles (where all three sides and angles are different). Triangles are used in many different areas of mathematics and science, including trigonometry, geometry, and physics.

Here,

We can use the trigonometric ratios of sine, cosine, and tangent to find the values of b and c. First, we can use the fact that the sum of the angles in a triangle is 180 degrees to find angle C:

C = 180 - A - B = 180 - 75 - 90 = 15 degrees

Next, we can use the definition of the sine ratio:

sin(A) = opposite/hypotenuse

to find c:

sin(75) = 5/c

c = 5/sin(75) ≈ 18.99

Finally, we can use the Pythagorean theorem:

a² + b² = c²

to find b:

b² = c² - a²

= (18.99)² - 5²

≈ 350.66

b ≈ √350.66 ≈ 18.72

Therefore, a ≈ 5, b ≈ 18.72, and c ≈ 18.99.

The volume of Eli's trophy case is 64.4 cubic feet.

Eli's trophy case's length, breadth, and height must be multiplied to determine its volume. The case has the following measurements:

Length = 4 3/5 feet

Width = 2 feet

Height = 3 1/2 feet

We can sum the improper fractions after converting the mixed integers to fractions to arrive at:

Length = 4 3/5 feet = (5*4 + 3)/5 = 23/5 feet

Height = 3 1/2 feet = (2*3 + 1)/2 = 7/2 feet

Now that we have the volume, we can multiply the length, width, and height:

Volume equals length, width, and height

= (23/5) feet x 2 feet x (7/2) feet

= (23 x 2 x 7)/(5 x 2) cubic feet

= (644/10) cubic feet

= 64.4 cubic feet

Therefore, 3 bakers can make 30 loaves of bread in 2 hours.

Therefore, 5 bakers can make 30 loaves of bread in 2 hours.

Therefore, 6 bakers can make 30 loaves of bread in 1.25 hours.

Therefore, 15 bakers can make 30 loaves of bread in 2 hours.

Step-by-step explanation:

In the number of bakers, it would take 2 hours to make 30 loaves of bread.

A proportion is an equation in which two ratios are set equal to each other.

Let h be the number of hours needed for a given number of bakers to make 30 loaves. Then we have:

2 bakers can make 30 loaves in 1 hour, so 1 baker can make 15 loaves in 1 hour.

Therefore:

3 bakers can make 45 loaves in h hours, so 45/3 = 15 loaves can be made in 1 hour. Thus, 3 bakers can make 30 loaves in 2 hours.

5 bakers can make 75 loaves in h hours, so 75/5 = 15 loaves can be made in 1 hour. Thus, 5 bakers can make 30 loaves in 2 hours.

6 bakers can make 90 loaves in h hours, so 90/6 = 15 loaves can be made in 1 hour. Thus, 6 bakers can make 30 loaves in 2 hours.

15 bakers can make 225 loaves in h hours, so 225/15 = 15 loaves can be made in 1 hour. Thus, 15 bakers can make 30 loaves in 2 hours.

Therefore, regardless of the number of bakers, it would take 2 hours to make 30 loaves of bread.

The maximum weight occurs when x = 0 and y = 0, and the maximum weight is W = 0.

In calculus, the derivative is a fundamental concept that measures the rate of change of a function with respect to its input variable. The derivative of a function at a particular point gives the instantaneous rate of change of the function at that point.

The derivative of a function f(x) with respect to its input variable x is denoted by f'(x) or df/dx. It is defined as the limit of the difference quotient as the change in x approaches zero:

f'(x) = lim (h → 0) [(f(x+h) - f(x)) / h]

Intuitively, the derivative of a function at a particular point gives the slope of the tangent line to the graph of the function at that point. This slope can be positive, negative, or zero, depending on whether the function is increasing, decreasing, or constant at that point.

To find the maximum weight, we need to find the critical points of the function.

First, we find the partial derivatives of the weight function with respect to x and y:

∂W/∂x = 8y(20 - 2x - 2y)

∂W/∂y = 8x(20 - x - 4y)

Setting these partial derivatives equal to zero, we get:

8y(20 - 2x - 2y) = 0

8x(20 - x - 4y) = 0

Solving for x and y, we get two critical points:

x = 0, y = 0

x = 10, y = 5

To determine which of these critical points correspond to a maximum, we use the second partial derivative test.

The second partial derivatives of W with respect to x and y are:

∂²W/∂x² = -32y

∂²W/∂y² = -32x

At the critical point (0,0), both second partial derivatives are negative, which means that it is a maximum.

At the critical point (10,5), both second partial derivatives are positive, which means that it is a minimum.

Therefore, the maximum weight occurs when x = 0 and y = 0, and the maximum weight is W = 0.

Joel cannot buy 2 games and 6 puzzles and satisfy the constraints was solved by using inequality.

The total cost of x puzzles and y games must be less than or equal to $96, which gives us the first inequality: 8x + 12y ≤ 96

The second inequality: x + y ≥ 9.

An inequality is a mathematical statement that compares two quantities or expressions and shows the relationship between them using one of the following symbols: <, >, ≤, or ≥. For example, "x > 5" is an inequality that states that x is greater than 5.

In the given question,

Part A:

Let x be the number of puzzles Joel can buy and y be the number of games Joel can buy.

The total cost of x puzzles and y games must be less than or equal to $96, which gives us the first inequality: 8x + 12y ≤ 96

Joel needs to buy at least 9 gifts, which means that the total number of gifts must be greater than or equal to 9. Since x represents the number of puzzles and y represents the number of games, the total number of gifts is x + y. This gives us the second inequality: x + y ≥ 9

We also know that Joel can only buy puzzles or games, not both. Therefore, x and y must be either both integers or both half-integers (such as 1.5 or 2.5), but they cannot be mixed. This gives us the third inequality:

x, y are both integers or both half-integers

Part B:

To see if Joel can buy 2 games and 6 puzzles and satisfy the constraints, we can substitute x = 6 and y = 2 into the inequalities:

8x + 12y ≤ 96

8(6) + 12(2) ≤ 96

72 ≤ 96

This inequality is true, so the first constraint is satisfied.

x + y ≥ 9

6 + 2 ≥ 9

8 ≥ 9

This inequality is not true, so the second constraint is not satisfied. Therefore, Joel cannot buy 2 games and 6 puzzles and satisfy the constraints.

Answer: 5

Step-by-step explanation:

A = Lw (area of rectangle is length times width)

A = 15 (Area is 15)

L = 2x + 5 (length is 2 times a number plus another 5)

w = x - 4 (width is 4 less than that number

Plug in the values:

15 = (2x + 5)(x - 4)

FOIL

15 = 2x2 - 8x + 5x - 20

simplify:

15 = 2x2 - 3x - 20

Subtract 15

0 = 2x2 - 3x - 35

Factor out the quadratic. We know that one number has to be 7 and the other 5 so that they multiply together to make 35, and that one of them has to be negative so that it's actually -35.

That means we have m * n = -35

We also need it set up so that so that 2m + n = -3:

2 * -5 + 7 = -3

0 = (2x + 7)(x - 5)

So:

0 = 2x + 7, or 0 = x - 5

x = -7/2 or 5

We cannot have a negative length, so x = 5

Check:

15 = (2 * 5 + 5) (5 - 4)

15 = 15 * 1

y = (-1/3)x + 2/3

Step-by-step explanation:

We can use the slope-intercept form of a linear equation to find the equation of the line passing through the points (5, -1) and (2, 2). The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:

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

Substituting the coordinates of the given points, we have:

slope = (2 - (-1)) / (2 - 5) = -1/3

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. We can use the point-slope form of a linear equation to find the y-intercept.

Using the point (5, -1), we have:

-1 = (-1/3)(5) + b

Solving for b, we get:

b = -1 + 5/3 = 2/3

Therefore, the equation of the line passing through the points (5, -1) and (2, 2) is:

y = (-1/3)x + 2/3

On solving the provided question, we can say that Hence, the solution to the system of equations is x = 19/8 and y = 5/8.

A math equation is a technique that links two statements and utilises the equals sign (=) to express equivalence. In algebra, an equation is a mathematical statement that proves the equivalence of two mathematical expressions. For example, in the computation 3x + 5 = 14, the equal sign inserts a gap between the numbers 3x + 5 and 14. A mathematical formula may be used to explain the link between the two phrases written on either side of a letter. The logo and the programme are usually the same. For example, 2x - 4 equals 2.

4x + 4y = 12 is obtained by multiplying the first equation by four.

To remove y, combine the first and second equations: (4x + 4y) + (4x - y) = 12 + 7, which simplifies to 8x = 19.

Divide both sides of the equation by 8 to find x: x = 19/8.

To find y, plug the value of x into either equation: y = 3 - x = 3 - 19/8 = 5/8.

Hence, the solution to the system of equations is x = 19/8 and y = 5/8.

Answer: 0.7

Step-by-step explanation: The tenths place in decimals is the number directly to the right of the decimal. the 5 next to the six is greater than or equal to 5 meaning you can round up the 6 to a 7.

Answer:

It depends on the equation in question. If Maggie is referring to an equation in the form of x = y, then adding 8 to both sides would still result in the same value of x and y being equal. For example, if the equation is 2x - 5 = 7, then adding 8 to both sides would result in 2x - 5 + 8 = 7 + 8, which simplifies to 2x + 3 = 15. In this case, adding 8 to both sides would not maintain equality.

However, if the equation is in the form of an inequality such as x < y or x > y, adding the same value to both sides may not maintain the inequality. For example, if the inequality is 2x - 5 < 7, then adding 8 to both sides would result in 2x - 5 + 8 < 7 + 8, which simplifies to 2x + 3 < 15. In this case, adding 8 to both sides would still maintain the inequality.

Therefore, whether or not adding 8 to both sides of an equation would still result in equality depends on the equation in question and the mathematical operation being performed.

Yes.  Yes I do.

If you think of an equation as a balance, where both sides have equal weight, then adding the same amount to both sides or taking away the same amount from both sides will still maintain that balanced weight.

We call this the addition property of equality:
