The value of side AB is 6 units for parallelogram ABCD with perimeter is 22 units.

An equation is an expression that shows how two or more numbers and variables are related to each other. Types of equations can either be linear, quadratic or cubic

Parallelogram is a quadrilateral (four angles and sides) in which opposite sides are equal and parallel.

From the diagram:

AB = DC  (opposite sides are equal)

2y + 1 = 4 - 4w

2y + 4w = 3    (1)

AD = BC  (opposite sides are equal)

3x - 2 = x - w + 1

2x + w = 3    (2)

The perimeter of ABCD is 22:

2(AB + AD) = Perimeter

2(2y + 1 + 3 - 4w) = 22

2(2y - 4w + 4) = 22

4y - 8w + 8 = 22

4y - 8w = 14    (3)

From the three equations:

w = -0.5, x = 1.75, y = 2.5

AB = 2y + 1 = 2(2.5) + 1 = 6 units

The value of side AB is 6 units

A constant polynomial is a polynomial with a degree of 0, meaning it has no variable terms. The only possible constant polynomial is the term with a coefficient of 3, which is 3.

This can be seen by looking at the formula for a polynomial, which is:

P(x) = a0 + a1x + a2x2 + ... + anxn,

where a0 is the constant term, a1 is the linear term, a2 is the quadratic term, and so on. Since this polynomial has no variable terms (x = 0), the only possible constant polynomial is the term with a coefficient of 3.

To calculate the value of a constant polynomial, you simply substitute 0 for x in the equation above. For example, in the polynomial 3, the value would be 3 when x = 0.

P(0) = 3

Therefore, the answer is option b, 3.

The quadratic equation written in the vertex form is:

f(x) = 2*(x - 2)^2 - 8

We know that for any parabola whose vertex is (h, k) and the leading coefficient is a, can be written in the vertex-form as:

f(x) = a*(x - h)^2 + k

In this particular case, we know that the vertex of the parabola is the point (2, -8), replacing that in the quadratic equation above we will get:

f(x) = a*(x - 2)^2  - 8

Now we also know that our parabola passes through the point (0, 0), then if we replace these values in the equation we will get:

f(0) = 0 = a*(0 - 2)^2 - 8

        0 = a*4 - 8

        8 = a*4

        8/4 = a

          2 = a

This is the method used for most calculations in mathematics. This method is useful when solving problems involving proportions and proportions, algebra, geometry, and more.

The unit method allows us to find missing values. For example, if a pack of juice costs $5. Then you can easily see that the cost is 5 packages, or $25.

According to the Question:

If Liam has $30 to spend and he must buy at least 9 drinks and tacos altogether, it means that,

$3.50 for 5 tacos

⇒ 3.50 x 5 =  $17.50

Now,

9 - 5 tacos = 4 drinks

Cost of 4 drinks x $2 = $8

The total price :

$17.50 + $8 = $25.50 out of $30 price limit

The height of the tailgate (from the ground), holding the 8 ft ramp inclined at 35° with the ground, found using trigonometric ratios is about 4.59 ft

A trigonometric ratio (trig ratio) specifies the relationship between an angle in a right triangle and two sides of the right triangle.

The length of the ramp = 8 ft

The angle the ramp forms with the ground = 35°

The ramp leads from the ground to the tailgate of the truck

The height of the tailgate from the ground can therefore be found using trigonometric ratios as follows;

The trigonometric ratio for the sine of an angle, θ, using SOH CAH TOA therefore is; sin(θ) = Opposite side

Where;

θ = 35°

The opposite side to the angle θ = Height of the tailgate from the ground = h

The hypotenuse side of the right triangle formed by the ramp = The length of the ramp = 8 ft. We get;

sin(35°) = (Height of the tailgate from ground, )/(Length of the ramp)

Therefore;

sin(35°) = h/8

The coefficient of x²y in the product ( 7x²-5y) ( x²+3y) is 16.

The coefficient of x²y in the product (7x²-5y) (x²+3y) is the numerical factor that is multiplied to x²y when the two polynomials (7x²-5y) and (x²+3y) are multiplied together.

To find the coefficient of x²y in the product, you can use the distributive property of multiplication over addition, also called the FOIL method, which states that to multiply two binomials, you must multiply the first term of the first binomial by the first term of the second binomial, the first term of the first binomial by the second term of the second binomial, the second term of the first binomial by the first term of the second binomial, and the second term of the first binomial by the second term of the second binomial.

The product of (7x²-5y) (x²+3y) can be expanded as follows:

(7x²-5y) (x²+3y) = 7x²x² + 7x²3y -5yx² -5y3y

=7x⁴ + 21x²y -5x²y - 15y²

The linear equation for a line made of points  (r,5) and (6,r) has slope = 5/8 so r=5.

What is a linear equation ?

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form

Ax + B = 0

e.g. x-10=0. Here, x is a variable, A is a coefficient and B is constant.

The standard form of a linear equation in two variables is of the form

Ax + By = C

e.g. 2x-4y=10. Here, x and y are variables, A and B are coefficients and C is a constant.

Now,

As slope (m)=(y2-y1)/(x2-x1)

and m=5/8, (x1,y1) and (x2,y2) are (r,5) and (6,r)

Therefore, 5/8=(r-5)/(6-r) --> 5(6-r)=8(r-5)--->13r=70-->r=5
