8. LaTrenda and Osman both play in the school band.
LaTrenda finds out that the trumpet produces sounds
around 88 decibels and the saxophone produces
sounds around 75 decibels. LaTrenda is worried about
whether or not playing all the instruments in the band
together will damage her hearing. Osman claims that
88 +75 decibels would be 163 decibels. which is very
dangerous to hearing. LaTrenda thinks that it might
make more sense to add the intensities of the sounds
of the two instruments played together and then
calculate the number of decibels. Who do you think is

Decide on the input values. Choose the output values. You should classify a connection as a function if each input value results in only one output value.

Any possible input value will result in exactly one output value, which is the definition of a function. "The output is a function of the input" is how we phrase it. The range is comprised of the output values, whereas the domain is made up of the input values. But not all relations are functions, and vice versa.

Formulas or graphs are typically used to depict functions.There are many different kinds of relations and functions, including empty relations, universal relations, reflexive relations, symmetric relations, transitive relations, equivalence relations, constant functions, polynomial functions, identity functions, on-to-one functions, onto functions, bijective functions, etc.

No relationship has the characteristics of a function if each input does not have a distinct output.There are nine different forms of mathematical relations: empty relation, full relation, reflexive relation, irreflexive relation, symmetric relation, anti-symmetric relation, transitive relation, equivalence relation, and asymmetric relation.

An ordered pair (x,y) represents a point on a coordinate plane, where x is the horizontal position and y is the vertical position. The quadrant in which this point lies can be determined by the signs of the x and y coordinates.

The quadrant that contains the point (4,3) is Quadrant 1. This is because both the x-coordinate (4) and y-coordinate (3) are positive, indicating that the point lies in the top-right region of the coordinate plane.

When 5/9 of the tank is filled in 2 minutes, then it will take 3.6 minutes to fill the entire tank.

The definition of a fraction is a fraction multiplied by another fraction, integer, or a group of variables. Given that the 5/9 tank fills in 2 minutes. The duration of this period in seconds is 60×5= 120 seconds.

So the time taken to fill a 1/9 tank is calculated as follows,

Time taken = 120/5

=24 seconds

The time taken to fill the 9/9 tank (full) is calculated by multiplying 24 seconds and 9, we get,

24×9 = 216 seconds

= 3.6 minutes.

Therefore, the required answer is 3.6 minutes.

The value of the angle tan(D) will be 53.13°.

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that the sides of the triangle are BC = 32 and CD = 24.

The value of tan(D) is calculated as,

The range of a function  is the set of all the y-values that you get when you plug all of the possible x-values into the function. It is also called a co-domain of function.

To find the range of function write down the function as y=f(x). Find all the minimum to a maximum value of y that satisfies f(x). The values obtained are the range of function. Plot the range on the graph.

For example, if you want to find the range of f(x) = 3x^2 + 6x -2. The lowest y-coordinate is at the vertex, -5, and the values for set y expand infinitely above this point. This means that the range of the function is y={-5, R}

The 4 types of exponents are positive, negative, zero, and rational.

When an expression or statement of specific natural numbers (0 to ∞), is represented as repeated power by multiplication of its units, then the resulting number is an Exponent.

For example, take the value 7⁵. Here the number 7 is called “base” and the number 5 (up) is called the exponent or power of that mathematical sequence. Now, to precisely calculate the value of this exponent, simply multiply the base number as many times as denoted by the power. So, for this case, it would be 7×7×7×7×7 = 16807.

We will use the method of linear equations to get the width of the rectangle, which is 15 inches.

Here we are given that the length of the rectangle is 10 inches and the perimeter is 50 inches.

We know that the perimeter of a shape is the length of the boundary of that shape.

The formula for the perimeter of a rectangle is 2(l + b)

= 2 X (length of the rectangle + breadth of the rectangle)

Here length, l = 10 inches, the perimeter is 50 inches, and we have been to consider breadth to be w inches.

Hence we can use the formula of the perimeter and the method of a linear equation to get the width.

Hence we get

2(10 + w) = 50

or, 10 + w = 25

or, w = 25 - 10

or, w= 15 inches.

We are told that for every hour x that Eva’s electric car charges, she can drive the car 7.5 miles. Eva needs to drive at least 60 miles tomorrow.

Now, 7.5 miles represents the speed per hour and we know that formula for distance is;

Answer:

(-2,3) or x= -2 and y= 3

Step-by-step explanation:

I didn't graph this, but you could.

For the first equation: Subtract x from both sides to get 2y= -x +4

Next divide both sides by 2 to get y= -1/2x + 2 (Now graph this)

For the second equation subtracted both sides by -3x to get 2y= -3x

Next, divide both sides by 2 to get y= -3/2x (Now graph this)



I used elimination. I wrote both equations out then subtracted 2y from both of them then did -2x = 4

x= -2

then I substitued -2 + 2y = 4

The equation of a line that is perpendicular to the line y = 34x + 5 and passes through the point (0, 3) is y = -34x + 3

The slope-intercept form of the equation of a line is y = mx + c, where

The slope of a line perpendicular to another line is the negative reciprocal of the original line's slope. In this case, the original line has a slope of 34, so the slope of the line that is perpendicular to it is -1/34.

To find the y-intercept of the line, we can use the point (0,3) that the line passes through. Substituting the x and y values of this point into the equation of the line, we get 3 = -34(0) + c, which simplifies to c = 3.

So the equation of the line that is perpendicular to y = 34x + 5 and passes through (0, 3) is y = -1/34x + 3

The formula for the area of a triangle is 1/2bh. This formula can be derived from the area of a parallelogram.

A parallelogram is a four-sided shape with two pairs of parallel sides. To find the area of a parallelogram, you need to multiply the base, b, by the height, h. This will give you the area of the parallelogram, which is bh. To find the area of a triangle, you need to divide the area of a parallelogram by two since a triangle has only one set of parallel sides. Therefore, the formula for the area of a triangle is 1/2bh. To calculate the area of a triangle, you need to multiply the base by the height and then divide the result by two. For example, if the base of a triangle is 8 cm and the height is 4 cm, the area of the triangle is 1/2 × 8 × 4 = 16 cm2.

In order to form a triangle, the sum of the length of two sides should be greater than the length of the third side. This is called the triangle inequality theorem.

Given the side lengths of 17 cm, 7 cm, and 8 cm, we can see that 17 cm is the longest side. To form a triangle, the sum of the other two sides (7 cm and 8 cm) should be greater than 17 cm.

7 cm + 8 cm = 15 cm which is less than 17 cm. Therefore, it is not possible to construct a triangle with sides 17 cm, 7 cm, and 8 cm.
