It akes 2.5 seconds for the football to reach its maximum height.
How to calculate the valueIt should be noted that to find the initial height of the football, we need to determine the height when t=0. We can substitute t=0 into the equation:
h(0) = -16(0)² + 80(0) + 1
h(0) = 1
We can find the time at which the vertical velocity is zero by finding the vertex of the parabolic function. The vertex can be found using the formula:
t = -b/2a
where a = -16 and b = 80. Substituting these values into the formula gives:
t = -80/(2(-16)) = 2.5
Therefore, it takes 2.5 seconds for the football to reach its maximum height.

What is equality for Class 7?
In mathematics, equality refers to the relationship between two expressions or values, indicating that they are equivalent or have the same value.
For example, the equation "2 + 3 = 5" states that the left side of the equation (2 + 3) is equal to the right side of the equation (5). Equality can be represented using the symbol "=", which is called the equality sign or equal sign.
Equality can also be used in other mathematical concepts such as congruence, similarity, and equivalence. For example, two triangles are congruent if they have the same shape and size, two figures are similar if they have the same shape but different sizes, and two equations are equivalent if they have the same solutions.
Equality in mathematics is transitive, meaning that if a = b and b = c, then a = c, and reflexive, meaning that a = a for any value of a.

Sarah needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 4. 25 hours and charged her $54 for parts. The total was $585. 25. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
The labour cost per hour charged by the technician for the laptop is $124.91
Here we see that it cost Sarah $54 dollars for the parts. Now, the technician charged her $585.25.
Since nothing else is mentioned, we will assume that the technician charged Sarah only for the parts and their labour hours.
Hence after deducting the charge for the computer parts, we can get the cost for the labour. We know the labour hours to be 4.25 hours. We don't know the labour cost, which is to be found.
Let the cost of labour per hour be $x
Hence the labour cost will be $4.25x
Adding the cost of parts will give us the charged amount. Hence we get
4.25x + 54 = 585
or, 4.25x = 531
or, x = 531/4.25
or, x = 124.941
Hence the cost per hour is $124.941

What is the formula for a 45 degree triangle?
Using the formula of Pythagorean Theorem we can find a 45 degree triangle.
The degrees of the triangle's three inner angles give rise to its name, 45, 45, and 90. The triangle formed by the angles 45, 45, and 90 is said to be isosceles since two of the angles are less than the third.
Due to the fact that this triangle has one angle that is precisely 90 degrees, it is also regarded as a right triangle.
The following guidelines apply to the 45-45-90 triangle's characteristics:
1. There must always be a right angle in one angle.
2. The second pair of angles must always be 45-degree angles.
3. A triangle has two equal-length sides, but the third side is always longer.
Using the Pythagorean Theorem - Since a 45-45-90 triangle has a right angle, the length of its sides may be calculated using the Pythagorean Theorem.

What are the 5 steps in solving rational inequality?
The following are the 5 steps in solving a rational inequality: simplifying the inequality, factoring the numerator and denominator of the inequality, set the numerator and denominator equal to zero.
Solving a rational inequality involves isolating the variable and determining the range of values that make the inequality true.
Simplify the inequality by clearing any fractions: This can be done by multiplying both sides of the inequality by the least common multiple (LCM) of the denominators of the fractions.
Factor the numerator and denominator of the inequality: This can be done to cancel out any common factors between the numerator and denominator.
Set the numerator and denominator equal to zero and solve for the zeros: This can be done to find the values of the variable that make the numerator and denominator equal to zero.
Test the zeros and any critical values: This can be done by substituting the zeros and critical values back into the inequality and determining if they make the inequality true or false.
Plot the solution on the number line: This can be done by plotting the zeros and critical values on a number line and shading the region that makes the inequality true.

The following bar graph summarizes the weather conditions in Crayonton for each day this month so far.
The reasonable estimate of the probability that it is sunny tomorrow is 25%.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Probability of an event is calculated by dividing the number of desirable outcomes by the total number of events possible.
From the graph, we have,
Number of days weather is sunny = 3
Total number of days = Days weather is sunny + Days weather is cloudy + Days weather is rainy + Days weather is snowy
Total number of days = 3 + 5 + 2 + 2 = 12
Probability that weather is sunny = 3 / 12 = 1/4 = 0.25 = 25%

What is the secant segment theorem?
The secant segment theorem states that If two secant segments intersect outside a circle, then the product of the secant segment with its external portion equals the product of the other secant segment with its external portion.
A secant is a line on the circle that connects exactly two distinct points on the curve. Secant is not a chord but a chord is part of a secant. Two different secants can intersect each other internally or externally.
Further, the secant segment theorem defines two more theorems or properties and they are:-
The angle formed by two internally intersecting secants in a circle is half the sum of the intercepted arcs.The angle formed by two externally intersecting secants in a circle is half the difference between the intercepted arcs.Arcs are line segment that is part of the circumference of a circle.

How to determine the area of the shaded section
In this problem we find the case of a shaded section, whose area must be determined. This can be realized by finding the area of rhombus OPQR and subtract the circular section OPR from it. All missing lengths of the triangles from the rhombus can be found by trigonometric functions.
The formula to determine the area of the shaded area is:
A = 2 · 0.5 · OR · RQ - (140 /360) · π · OR²
RQ = OR · tan 70°
If we know that OR = 12 m, then the area of the shaded section is:
RQ = 12 · tan 70°
RQ = 32.970
A = 2 · 0.5 · OR · RQ - (140 /360) · π · OR²
A = OR · RQ - (7π / 18) · OR²
