Equations with exponents, coefficients, and variables are called polynomial equations.

Polynomial equations are equations that contain variables, exponents, and coefficients. The greater exponent is referred to as the degree of the equation and it can have many exponents.

A polynomial is an expression in mathematics made up of coefficients and indeterminates, which are also known as variables. It can only be solved using the addition, subtraction, multiplication, and powers of positive-integer variables.

When a variable in an equation like the quadratic equation, cubic equation, etc. has only non-negative integer powers or only positive integer exponents, the function is said to be polynomial.

The absence of square roots of variables, fractional or negative powers on the variables, and the absence of variables in any fraction's denominator are specifically required for an expression to qualify as a polynomial term.

Therefore, the correct answer is option iii) -7 v² - 6v + 4.

y(t) = 3u(t) is a constant function that is equal to 3 for t >= 0 and equal to 0 for t < 0.

The function x(t) = 3tu(t) is a product of a scalar 3 and a unit step function u(t). Here, u(t) is defined as:

u(t) = 0 for t < 0

u(t) = 1 for t >= 0

So, x(t) is equal to 3t for t >= 0 and equal to 0 for t < 0.

The function y(t) is the derivative of x(t) with respect to t. To find the derivative of x(t), we use the power rule for differentiation, which states that the derivative of tx(t) is x(t) + t × dx(t)/dt.

So, we have:

y(t) = dx(t)/dt = d(3tu(t))/dt = 3u(t) + 3tu'(t) = 3u(t)

Here, u'(t) is the derivative of u(t) with respect to t, which is equal to the Dirac delta function δ(t).

So, we have:

y(t) = 3u(t) = 3 for t >= 0

y(t) = 0 for t < 0

Hence, y(t) = 3u(t) is a constant function that is equal to 3 for t >= 0 and equal to 0 for t < 0.

c. 100·π square units

4. a. 216·π square units

b. 48·π square units

c. 48·π square units

5. To complete the task, two circles of 1 ft radius should be cut from the carpet, followed by cutting a rectangular shape of width 4 ft and length of 2·π ft

The surface area of a solid is the sum of the areas that form a boundary around the outer part of the solid.

1 The surface area of a cube is A = 6·s²

a. When s = 5, A = 6 × 5² = 150

b. When s = 6 ft, A = 6 × 6² = 216

c. When s = 12 mm, A = 6 × 12² = 864

2. The surface area of a rectangular prism is; S.A. = 2·l·w + 2·h·w + 2·l·h

a. l = 2, w = 5, h = 7

Surface area = 2 × (2 × 5 + 5 × 7 + 2 × 7) = 118

b. l = 16 in, w = 11 in, h = 10 in

The surface area = 2 × (16 × 11 + 16 × 10 + 10 × 11) = 892

3. The surface area of a sphere, A  = 4·π·r²

a. The radius of the sphere, r = 12

A = 4 × π × 12² = 576·π

b. r = 16, therefore;

A = 4 × π × 16² = 1024·π

c. When the diameter, d = 10, we get;

A = 4·π·r² =  4·π·(d/2)² =  4·π·d²/4

A = 4·π·d²/4 = π·d²

4. The surface area of a cylinder, A = 2·π·r·h + 2·π·r²

a. r = 6, h = 12, therefore;

A = 2×π×6×12 + 2×π×6² = 216·π

b. r = 2, h = 10, therefore;

A = 2×π×2×10 + 2×π×2² = 48·π

c. r = 3, h = 5, therefore;

A = 2×π×3×5 + 2×π×3² = 48·π

5. The diameter of the cylinder = 1 ft

Height of the cylinder = 4 ft

The area for the carpet to cover the each of the top and bottom = π×1² ft² = π ft²

The area to cover the curved surface = 2 × π × r × h

Therefore, area of the curved surface = 2 × π × 1 × 4 = 8·π

Area of the curved surface = 8·π ft²

The linear equation representing Mia's situation is y = 3x + 12.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The two points given are - (4,24) and (6,30)

The slope-intercept form of a linear equation is - y = mx + b, where m is the slope and b is the y-intercept.

To find the slope use the formula -

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

m = (30 - 24)/(6 - 4)

m = 6/2

m = 3

So, now the equation becomes - y = 3x + b

To find the y-intercept substitute the equation with x and y values -

24 = 3(4) + b

24 = 12 + b

b = 24 - 12

b = 12

So, now the equation becomes - y = 3x + 12.

The critical chi-square value for a chi-square test with seven classes and a p-value of 0.05 is 12.59.

A hypothesis is an educated guess or prediction about a relationship between variables. The critical chi-square value is the value that is used to make a decision about the hypothesis.

If the calculated chi-square value is greater than the critical chi-square value, we reject the null hypothesis, which states that there is no significant difference between the expected and observed frequencies.

For a chi-square test with seven classes, the critical chi-square value can be found by looking at the critical chi-square values for a p-value of 0.05, as shown in Table 1.

The degrees of freedom (df) is equal to the number of classes minus 1, so in this case, df = 7 - 1 = 6.

The larger radius of Cylinder P, which produces a lower the height per unit volume, compared to the smaller radius of Cylinder Q, indicates;

Graph a, matches the graph of Cylinder Q

Graph b, matches the graph of Cylinder P

The volume of water in a cylinder can be found using the formula;

V = π·r²·h

The volume of water is therefore, directly proportional to the volume, therefore, we get;

V ∝ h

V = k·h

Where; k = The constant of proportionality = The slope of the graph of the proportional relation

The equation, V = π·r²·h, indicates that we get;

k = π·r²

The value of the radius for P, r₁ is larger than the value of the radius for Q, r₂

Therefore, k₁ = π·r₁² > k₂ = π·r₂²

h = V/(π·r²)

Therefore, for a specified volume, V, V/π·r₁² < V/π·r₂², h₁ < h₂, and as the water is added, the height of the water in Cylinder Q increases more than the height of the water in Cylinder P, which indicates that we get;

Let x be the length in minutes of a sitcom and y be the length in minutes of a drama.

We can write the following system of equations to represent the situation:

6x + y = 179

6x + 4y = 302

To solve the system using elimination, we can multiply the first equation by 4 to make the coefficients of y equal, and then subtract the second equation from the first:

24x + 4y = 716

6x - 4y = -123

18x = 593

Finally, we can divide both sides of the equation by 18 to find x:

x = 33

So, each sitcom is 33 minutes long. To find the length of each drama, we can substitute the value of x into either of the original equations:

The distance between any two raisins will not change when the bread doubles its size.

This is because the proportion of the raisins to the size of the dough remains constant. Mathematically, this can be expressed as:

Let d = the original distance between any two raisins

Let n = the new (doubled) size of the bread

d/n = constant

This means that when the size of the bread (n) doubles, the distance between the two raisins (d) remains unchanged.
