The total number of ants and spiders can be represented using the expression 6a+8s.

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.

1) Given a is for total number of ants and s is for total number of spiders.

If  for one ant, number of legs is 6 legs, then for a number of ants,

total number of legs = 6×a = 6a

Similarly for s number of spiders, total numbers of legs = 8 × s = 8s

Therefore ,Total number of legs of all ants and spiders in terrarium = 6a + 8s

2) The term 6a represent the total number of legs of all ants in terrarium.

    The term 8s represent the total number of legs of all spiders in terrarium.

Hence the expression 6a+8s.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

Given the function that models the height of a ball

s(t) = -16t² + 48t

At maximum height, the velocity is zero ie. ds/dt  = 0

ds/dt = -16t² + 48t

0 = 48 - 16t

It is possible to add constants in an algebraic expression. A constant is simply a number and it can be added or subtracted from any algebraic expression just like a variable. This is true.

For example, consider the algebraic expression 2x + 3. If we want to add a constant c to this expression, we can do so by adding c to both sides of the equation:

The resulting expression is 2x + 3 + c. This new expression represents the same mathematical relationship as the original expression, but with an additional constant term.

It's also important to note that constants can be added, multiplied and divided to an algebraic expression and the resulting expression is still algebraic.

Also, it is important to note that adding a constant to an expression doesn't change the variable, it only changes the constant part of the equation.

Answer:

C.

Step-by-step explanation:

The equation of the linear graph is y = x-2

A linear equation is an algebraic equation of the form y=mx+c. involving only a constant and a first-order (linear) term, where m is the slope and c is the y-intercept. Linear equation can also be defined as an equation with the highest power of the variable to be 1.

on the graph, the y intercept is the point where the graph line crosses the y axis. Therefore the y intercept is -2

The slope of the line = 0-(-2)/2-0

slope = 2/2 = 1

therefore the equation of the graph is ;

y = mx+c

y = x+(-2)

y = x-2

therefore the equation of the linear graph = y = x-2

So, the degree measure of one angle of a 30-sided regular polygon is 5,040°.

The degree measure of an angle is a measure of the size of the angle, in degrees. Angles are typically measured in degrees, with a full circle being 360°. The degree measure of an angle can range from 0° to 360°, with smaller angles having a degree measure between 0° and 90°, right angles having a degree measure of 90°, and larger angles having a degree measure between 90° and 360°.

To find the degree measure of one angle of a 30-sided regular polygon, we can use the formula:

angle measure = (n-2) * 180° / n

where n is the number of sides in the polygon. Plugging in n = 30, we get:

angle measure = (30-2) * 180° / 30 = 28 * 180° / 30 = 5,040°

Therefore, the degree measure of one angle of a 30-sided regular polygon is 5,040°. The correct answer is therefore 5,040°.

y = −2x+3 is Neither parallel nor perpendicular to line a.

y = −2x+5 is Parallel to line a.

y = (1/2)x+7 is  Perpendicular to line a

The slope-intercept form of the equation a straight line is:

y = mx + c,

where m is the slope and c is the y-intercept

When two lines are perpendicular, the product of their slope is -1 i.e.

m₁ × m₂ = -1

where m₁ and m₂ represent the slope of the lines

But when two lines are parallel, they have the same slope i.e.

m₁ = m₂

Let's examine the equations:

Line a, y = −2x+3

y = 2x-1

y = −2x+5

y = (1/2)x+7

For Line a and  y = 2x-1:

Comparing their slopes. So y = −2x+3 is Neither parallel nor perpendicular to line a

For Line a and y = −2x+5:

They have the same slope (-2). So y = −2x+5 is Parallel to line a

For Line a and y = (1/2)x+7:

(1/2) × −2 = -1.  The product of their slope is -1 (i.e. 1/2 × −2 = -1 ). So  y = (1/2)x+7 is  Perpendicular to line a

D) The value of x is 12 units in the triangle shown below:

The value of the base of a right angled triangle, given the length of the hypotenuse is 13 units and the length of the perpendicular is 5 units, is 12 units.

This can be determined by using the Pythagorean Theorem, which states that the square of the length of the hypotenuse of a right angled triangle is equal to the sum of the squares of the lengths of the other two sides (a^2 + b^2 = c^2). In this case, the hypotenuse is 13 units long, and the perpendicular is 5 units long,

so the equation would be: a^2 + 5^2 = 13^2, which can be simplified to: a^2 = 169-25 = 144. Therefore, a = √144 = 12.

The day in which this company sold the same number of each player is on the 13th day.

The number of players on the 13th day is 2,451 players.

In order to determine the days in which this company sold the same number of each player, we would have to equate the linear equation representing Music player A to the quadratic function representing Music player B and then solve for the value of x.

By equating equation 1 and equation 2, we have the following:

y = 191x - 32             .........equation 1.

y = -x² + 200x + 20     ......equation 2.

191x - 32 = -x² + 200x + 20

x² - 200x - 20 + 191x - 32 = 0

x² - 9x - 52 = 0

Next, we would solve the above quadratic equation by using the factorization method;

x² - 13x + 4x - 52 = 0

x(x - 13) + 4(x - 13) = 0

(x + 4)(x - 13) = 0

x = -4 or 13 days.

Therefore, the company sold the same number of each player on the 13th day.

For the number of players, we have:

y = 191x - 32

y = 191(13) - 32

y = 2,483 - 32

y = 2,451 players.
