For a 44° elevation angle, the grade will be 96%.

Given that,

if the angle of elevation of the road is 44 degrees,

The difference in the road's altitude over a horizontal distance of 100 feet is what is referred to as the percentage grade. For instance, a road with a 5% slope will rise 5 feet for every horizontal 100-foot distance.)

A tangent ?

One of the six basic trigonometric functions is tangent, denoted as tan().

The ratio of the opposite side length to the adjacent side length is the definition of the tangent value of the one sharp angle,, in a right triangle.

[tex]tan \alpha = sin\alpha /cos \alpha[/tex]

The tangent of the angle is the ratio of rise to run.

tan(angle) = grade

tan(44°) ≈ 0.96 = 96%

Therefore, The grade will be 96% for an angle of elevation of 44°.

The mid-point of two coordinates is the average of the x and y coordinates thus the midpoint of the line segment with endpoints (-6,-10),(-2,-8) is (-4,-9).

A line section that can connect two places is referred to as a segment.

A line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

The midpoint associated with two points (x₁, y₁) and (x₂, y₂) is given by

x = (x₁ + x₂)/2 , y = (y₁ + y₂)/2

x = (-6 - 2)/2 = -4 , y = (-10 - 8)/2 = -9

So, the coordinate will be (-4,-9).

Hence "The mid-point of two coordinates is the average of the x and y coordinates thus the midpoint of the line segment with endpoints (-6,-10),(-2,-8) is (-4,-9)".

The measurement of the largest square tiles she can use is 6 feet.

Finding all common factors between two numbers and choosing the biggest one yields the highest common factor (HCF). For instance, the numbers 8 and 12 share the elements 1, 2, and 4. Four is the greatest common factor.

Steps for calculating HCF:

Step 1: Write each integer as the sum of its prime factors in step one.

Step 2: List the shared factors between the two numbers.

Step 3: The HCF is the sum of all the common prime factors ( use the lower power of each common factor)

Given,

Measurement of the rectangular floor:

length = 150 feet

breadth = 132 feet

The measurement of the largest square can be calculated by finding the HCF of 132 and 150.

132 = 2*2*3*11

150 = 2*3*5*5

So, HCF (132, 150) = 2*3 = 6.

Hence, the measurement of the largest square tiles she can use is 6 feet.

You have the following expression:

39 + (-20.4)

In order to simplify the previous expression, you first eliminate the parenthesis. To do that, you take into account that the sign before the parenthesis must multiply the sign inisde. In this case, you have a positive sign + before the parenthesis, and inside you have a minus -. When the parenthesis is eliminated, these signs are multiplied (here you use the multiplication rule for signs). Thus, you have that - x + = - (positive multiplied by negative is equal to negative). And the expression becomes:

39 + (-20.4)

= 39 - 20.4

= 18.6

Hence, the simplified expression is 18.6

Let's begin by listing out the information given to us:

216^(-2n) = (1/6)^(3n+2)

6 is a factor of 216: 216 = 6³

1/6 = 6^(-1)

⇒ 6^(-2*3n) = 6^[(-1*(3n+2)]

⇒ 6^(-6n) = 6^(-3n-2)

Since both sides are in the same base, we equate the exponents. We have:

-6n = -3n - 2

Add "6n" from both sides, we have:

-6n + 6n = -3n + 6n - 2 ⇒ 0 = 3n - 2

⇒ 3n = 2

The location of √ 7 on a number line between 2 and 3.

A number line is a picture of a graduated straight line that serves as a visual representation of real numbers in primary mathematics. Every number line point is considered to correspond to a real number and every real number to a number line point.

A number line is a long straight line with numbers marked at equal intervals. On a number line, we can argue that as we move to the right, the value of numbers increases. This signifies that the numbers on the right are more than those on the left.

A number line shows how numbers are related. It's a line with check marks next to each number. The numerals get smaller as you move left on the number line. The numbers grow larger as you move closer to the number line.

The sum of three consecutive integers is 228. You can write this situation, in an algebraic way, as follow:

x + (x + 1) + (x + 2) = 228

where the lower number is x, and the largest number is (x + 2).

You solve the previous equation for x:

x + (x + 1) + (x + 2) = 228 eliminate prenthesis

x + x + 1 + x + 2 = 228 sum similar terms

3x + 3 = 228 rest 3 both sides

3x = 228 - 3

3x = 225 divide by 3

x = 225/3

x = 75

Then, the lower number is 75, and the largest one is (75+2) = 77

The quadratic function in this problem is defined as follows:

y = x² + 3x + 1.

Hence the coefficients are given as follows:

a = 1, b = 3, c = 1.

The x-coordinate of the vertex is given as follows:

x = -b/2a = -3/2.

The y-coordinate of the vertex is then given as follows:

y = (-3/2)² + 3(-3/2) + 1

y = 9/4 - 9/2 + 1

y = 9/4 - 18/4 + 4/4

y = -5/4.

Hence the vertex-form definition of the quadratic equation is given as follows:

y = (x + 3/2)² - 5/4.

Due to the positive leading coefficient, the vertex means that the function has a minimum of y = -5/4 at x = -3/2.

The domain of the function is all real values, as the quadratic function has no constraints such as a fraction or an even root.
