The net yardage the Bobcats football coach logged over four plays of game is  19.8x - 11.1y

The net yardage is calculated using the addition and subtraction operation as follows

For the gains the calculation is as follows

= Gain 25x yards + Gain 0.9y yards.

= 25x + 0.9y

For the lose the calculation is as follows

= Lose 12y yards + Lose 5.2x yards.

= 5.2x + 12y

the net yardage is solved as follows

net yardage = gains - loses

net yardage = (25x + 0.9y) - (5.2x + 12y)

removing the parenthesis and rearranging

net yardage = 25x + 0.9y - 5.2x - 12y

net yardage = 25x - 5.2x + 0.9y - 12y

net yardage = 19.8x - 11.1y

Answer:

The answer is C

Step-by-step explanation:

Bob's gift shop sold a total of 825 cards for Mother's Day.

To calculate the total number of cards sold for Mother's Day, we can use the following formula:

Total Cards Sold = (Number of Cards Sold by Salesman) / (Percent of Cards Sold by Salesman)

In this case, the total number of cards sold for Mother's Day would be calculated as:

Total Cards Sold = (33 cards) / (4%)

Using the above formula, the total number of cards sold for Mother's Day would be 825 cards.

To arrive at this answer, we first converted 4% to a decimal by dividing it by 100. This gave us 0.04. We then divided 33 cards by 0.04 to get 825 cards.

Therefore, Bob's gift shop sold a total of 825 cards for Mother's Day.

The value of n in the vertical angles is 5 4 / 5.

Vertical angles are angles that are opposite of each other when two lines intersect each other.

Vertical angles share the same vertex. Vertically opposite angles are congruent to each other.

The measures of the two angles are 2n + 18 and 7n - 11. They are vertical angles.

Therefore, the two vertically opposite angles are congruent to each other. We will use the congruency to find the value of n in the equation.

2n + 18 = 7n - 11

2n - 7n = -11 - 18

-5n = -29

divide both sides by -5

n = -29 / -5

n = 29 / 5

The SAS (Side-Angle-Side) Congruence Rule states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the two triangles are congruent.

The SAS (Side-Angle-Side) congruence rule is a method used to determine if two triangles are congruent. This rule states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

To determine if two triangles are congruent using the SAS rule, we must first identify the two sides and the angle in one triangle that are congruent to the two sides and the angle in the other triangle. This means that they must have the same measures in terms of length and angle.

Once we have identified the corresponding sides and angles, we can use the SAS rule to determine if the two triangles are congruent. If the two sides and the angle of one triangle are congruent to the two sides and the angle of another triangle, then the two triangles are congruent.

However, if the two sides and the angle of one triangle are not congruent to the two sides and the angle of another triangle, then the two triangles are not congruent. The SAS rule is a simple and effective way to determine if two triangles are congruent.

The given model is exponential.

The formula for an exponential function is f (x) = ax, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.

When b > 0 and b 1, an exponential function has the form f(x) = bx. The base is b, and the exponent is x, just like in any exponential expression. The development of bacteria is an illustration of an exponential function. Some germs multiply by two per hour.

The height of the cone is 16 feet.

A cone is a three-dimensional geometric shape.

The right cone has a slant height of 20 ft and the diameter of the base is 24 ft.

Therefore, the height of the cone can be found as follows:

Using Pythagoras's theorem,

c² = a² + b²

where

The slant height of the cone is the hypotenuse side of the detached right triangle. The radius and the height of the cone is the other legs of the detached right triangle.

Hence,

diameter = 24 ft

r = radius = 24 / 2  = 12 ft

Hence,

The domain is the area enclosed by the circle, which is all the points inside the unit circle.

The domain of a function is the set of all possible input values (x, y) for which the function is defined and produces a valid output.

For f(x, y) = ln(25 − x2 − 25y2), the function is defined as long as 25 − x2 − 25y2 > 0. This is because the natural logarithm (ln) is only defined for positive numbers. To find the domain, we can set 25 − x2 − 25y2 > 0 and solve for x and y.

25 − x2 − 25y2 > 0

x2 + 25y2 < 25

x2 / 25 + y2 < 1

This is the equation of a unit circle centered at (0,0) with a radius of 1.

So the domain is the area enclosed by the circle, which is all the points inside the unit circle.

The derivative of the function h(x) = 1 - x^2 sin^-1(x) -x^2-x is h'(x) = - x^2/(sqrt(1-x^2)) - 2x - 1.

What is derivative ?

The derivative of a function is a measure of how much the output of the function changes with respect to the change in its input. It is represented by the symbol "d/dx" or "∂/∂x" and it is a fundamental concept in calculus.

First, we will apply the chain rule to the term -x^2 sin^-1(x)

Let u = sin^-1(x)

du/dx = 1/(sqrt(1-x^2))

so, -x^2sin^-1(x) = -x^2u

then dh/du = -x^2

then dh/dx = -x^2 * (du/dx) = -x^2/(sqrt(1-x^2))

Next, we will differentiate the rest of the function ,

h(x) = 1 - x^2sin^-1(x) - x^2 - x

h'(x) = - x^2/(sqrt(1-x^2)) - 2x - 1

So, the derivative of the function h(x) = 1 - x^2 sin^-1(x) -x^2-x is h'(x) = - x^2/(sqrt(1-x^2)) - 2x - 1.

An equation that can you use to find h, the height of the window in meters is: A. 1/2(2h - 2)h = 42.

The height of the window in meters is equal to 7 meters.

Mathematically, the area of a triangle can be calculated by using this mathematical expression:

Area of a triangle = 1/2 × b × h

Where:

Since the window's base area is 2 meters shorter than twice the height, a mathematical expression which can be used to represent it is given by:

Base area, b = 2h - 2

Substituting the given parameters into the area of a triangle formula, we have the following;

Area of a triangle = 1/2 × b × h

42 = 1/2 × (2h - 2) × h

1/2(2h - 2)h = 42 [required equation].

Making the variable h the subject of formula, we have the following;

1/2(2h - 2)h = 42

Cross-multiplying, we have:

(2h - 2)h = 84

2h² - 2h = 84

2h² - 2h - 84 = 0

Dividing all through by 2, we have the following:

h² - h - 42 = 0

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

h² - 7h + 6h - 42 = 0

h(h - 7) + 6(h - 7) = 0

(h + 6)(h - 7) = 0

h = -6 or 7 meters.

Therefore, the height of the window is 7 meters since it can't be negative.

Step-by-step explanation:

The y-intercept represents the number of snapper fish in the area in 2004, which is the year that t = 0.

An area can be represented by the given formula:

[tex]F = 1500(1.02)^t[/tex]

where t represents the number of years since 2004.

The y-intercept of this equation is the point where the graph of the equation crosses the y-axis. In other words, it is the value of F when t is equal to 0.

Plugging in t = 0 into the equation above gives us:

F = 1500(1.02)⁰

= 1500(1)

= 1500

So the y-intercept of this equation is 1500.

Since Elena's distances and times for a training run are given by the equation y = 8.5x, Tyler’s pace per minute is equal to 8.2 miles per minute.

In order to determine Tyler’s pace per minute, we would have to determine the rate of change (slope).

Mathematically, the rate of change is also referred to as slope and it can be calculated by using this formula;

Rate of change (slope), m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Rate of change (slope), m = (y₂ - y₁)/(x₂ - x₁)

Next, we would determine the rate of change with respect to Tyler’s pace per minute, with the following data points (0, 0) and (1, 8.2):

Rate of change (slope), m = (0 - 8.2)/(0 - 1)

Rate of change (slope), m = -8.2/-1

Rate of change (slope), m = 8.2.
