The relation is a function if every ordered pair has one value of x, which means x does not repeat

Let us study each relation

a) {(5, 1), (-2, 4), (1, 1), (5, 2)}

Since each ordered pair has a different value of x

There are 2 ordered pairs that have x = 5

This relation is not a function

b) {(1, 4), (-2, 2), (5, 1), (-6, 2)}

Since no repeated x in the ordered pairs

Then the relation is a function

c) There are 2 ordered pairs with x = -2

It is not a function

d) There are 2 ordered pairs with x = 1

It is not a function

The answer is b

The equation of the model is 42 × ? = 5,964.

Here we have to find the equation of the model

Area of a rectangle:

The area of a rectangle is equal to the product of length into breadth.

Area of rectangle = length× breadth

length =?

breadth = 42

Area = 5,964

So we have an equation:

?× 42 = 5,964

a) 5,964/ 42 = ?

5,964 = 42 × ?

So it is correct

b) 5,964-? =42

5,964 = 42 + ?

So it is not correct.

c) 5,964/ ? = 42

5,964 = 42× ?

So it is correct

d) 42 ×? = 5,964

So it is correct.

Therefore option b i.e., 5,964 - ? = 42 is the equation that is not represented by the model:

ANSWER :

d. cot θ

EXPLANATION :

Note that the reciprocal of tangent is cotangent.

If reciprocals are multiplied with each other, the result is 1.

From the problem, we have :

Since the result of the product is 1, the tangent function must be multiplied by its reciprocal.

That will be cotangent.

Or we can just simply divide the equation by tan θ.

The slope and y-intercept of 2y = 6x - 12 are 3 and (-6) respectively.

What is the slope intercept form of a line?
The line with m as the slope, and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.
The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, c, denotes the y-coordinate of the location where the line's graph crosses the y-axis.

Given, the equation of the line is 2y = 6x - 12
Dividing the given equation by 2 we get, y = 3x - 6 ⇒ y = 3x + (-6)
Comparing the equation with the standard form of slope intercept form of a line as established in literature, we have:
Slope = m = 3 and y-intercept = c = -6
Thus, the slope and y-intercept of 2y = 6x - 12 are 3 and (-6) respectively.

The total sale based on cost of 87.64 and sales tax percentage of 7% is 93.77

What is sales tax?

Sales tax is the  levy charged on goods and services that is remitted by the seller to the government, in some jurisdictions, it is known as value-added tax and it should be noted that it increases the sales, in essence, the total sale in this case is the cost of groceries which is 87.64 plus 7% of that amount which is sales tax on the cost of the groceries

cost of groceries=87.64

sales tax=7%*cost of groceries

sales tax=7%*87.64

sales tax=6.13

total sale=cost of groceries+sales tax

total sale=87.64+6.13

Answer:

Line A: 4

Line B: -2

Step-by-step explanation:

Note: gradient means slope, or m, in this context

To find the slope of a line, use the formula:

[tex]m = \dfrac{\Delta y}{\Delta x} = \dfrac{y_2-y_1}{x_2-x_1}[/tex]     where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points on the line

Line A has points (2, 2) and (3, 6). To find the slope of the line, simply plug these values into the formula for m :

[tex]m_{\mathrm{line \, A}}=\dfrac{6-2}{3-2}=\dfrac{4}{1}=4[/tex]

So, the slope, or gradient, of line A is 4.

Next, do the same thing for Line B.

Find two points on the line:

(0, 8) and (1, 6)

And plug these values into the formula:

[tex]m_{\mathrm{line \, B}}=\dfrac{6-8}{1-0}=\dfrac{-2}{1}=-2[/tex]

So, the slope, or gradient, of line B is -2.

The rate of change of the area is -80.5 [tex]inches^{2}[/tex]/sec.

Given:

A right triangle has legs of 21 inches and 28 inches whose sides are changing.The short leg is decreasing by 2 in/sec and the long leg is shrinking at 5 in/sec.

Let's set the two legs as a and b, so the lengths are:

a = 21 - 2t

b = 28 - 5t

The area is:

area a = ab /2

= (21 - 2t) (28 - 5t)/2

= (588 - 105t - 56t + 10[tex]t^{2}[/tex]/2

a = 5[tex]t^{2}[/tex] - 161t/2 - 299

The rate of change of the area is:

da/dt = d(5[tex]t^{2}[/tex] - 161t/2 - 299)/dt

da/dt = 10t -161/2

And at t=0,

= 10(0) - 161/2

The rate of miles per gallon is 24.5 miles/gallon and an equation for the  proportional relationship is 1 : 24.5 and we can drive 1592.5 miles on 65 gallons of gas.

In proportionality, Algebra demands that two ratios be equal. A/B = C/D denotes the ratio of a and b to c and d. When using a proportion to solve a word problem, one of the four quantities is usually unknown.

It can be resolved by multiplying one numerator by the opposing denominator, adding the resulting number, and then solving for the other numerator and denominator.

Proportionality refers to any relationship that consistently has the same ratio. For instance, the number of trees in an orchard and the quantity of apples in a crop are determined by the average number of apples per tree.

It is given that,

A test of a new car shows it can drive 357.7 miles on 14.6gallons of gas.

We need to find how far you could drive on 65 gallons of gas.

14.6 gallons of gas = 357.7 miles

miles per gallon =  357.7 miles/14.6 gallons

                           = 24.5 miles/gallon

For 65 gallons of gas

The lower bound for the length of the remaining ribbon is 13.8 cm, and the upper bound is 15.8 cm.

Here,

To work out the lower and upper bounds for the length of the remaining ribbon, we need to consider the possible scenarios that would result in the smallest and largest remaining lengths.

Given:

Original length of ribbon = 23 cm (correct to the nearest cm)

Length of the piece cut off = 87 mm (correct to the nearest mm)

First, let's convert the length of the piece cut off to centimeters:

1 cm = 10 mm

So, 87 mm = 87 / 10 cm = 8.7 cm (correct to the nearest mm)

Now, let's calculate the upper bound for the remaining ribbon length:

Upper bound = Original length - Length cut off + Tolerance

Upper bound = 23 cm - 8.7 cm + 0.5 cm (maximum possible rounding error for 87 mm)

Upper bound = 23 cm - 8.7 cm + 0.5 cm = 15.8 cm

Next, let's calculate the lower bound for the remaining ribbon length:

Lower bound = Original length - Length cut off - Tolerance

Lower bound = 23 cm - 8.7 cm - 0.5 cm (maximum possible rounding error for 87 mm)

Lower bound = 23 cm - 8.7 cm - 0.5 cm = 13.8 cm

So, the lower bound for the length of the remaining ribbon is 13.8 cm, and the upper bound is 15.8 cm.

The solution of the equation is not extraneous.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The algebraic expression is,

⇒ Square root of quantity 2x plus 8 end quantity equals 6.

Now,

Since, The algebraic expression is,

⇒ Square root of quantity 2x plus 8 end quantity equals 6.

Hence, The mathematical expression is,

⇒ √2x + 8 = 6

Solve for x as,

⇒ √2x + 8 = 6

Take square both side, we get;

⇒ 2x + 8 = 36

⇒ 2x = 36 - 8

⇒ 2x = 28

⇒ x = 14

So, The value of x = 14

Since, The solutions of an equation are known as extraneous solutions if they are invalid.

Hence, Substitute x = 14 in above equation, we get;

⇒ √2x + 8 = 6

⇒ √2 × 14 + 8 = 6

⇒ √36 = 6

⇒ 6 = 6

Thus, The solution is not extraneous.
