Answer:

Step-by-step explanation:

A quadratic inequality is one that involves a quadratic polynomial.

Identification

The degree of a polynomial is the value of the largest exponent of the variable. When the degree of a polynomial is 2, we call it a quadratic.

For the following inequalities, the degree of the polynomial in x is shown:

y < 2x +7 . . . degree 1y < x^3 +x^2 . . . degree 3y < x^2 -5x . . . degree 2 (quadratic)

Application

We see that the degree of the polynomial in x is 2 in ...

   y < x^2 -5x

so that is the quadratic inequality you're looking for.

Additional comment

When a term involves only one variable, its degree is the exponent of that variable: 5x^3 has degree 3. When a term involves more than one variable, the degree of the term is the sum of the exponents of the variables: 8x^4y3 has degree 4+3=7.

How many revolutions will a car wheel of diameter 22 in. make as the car travels a distance of one mile

Answers

It would be take upto 999 revolutions.

Let try to solve it,

Let n represent number of revolutions.

We are asked to find the number of revolutions it will take for a car wheel of diameter 30 in. to travel a distance of one mile.

1 mile = 63360 inches.

We will use circumference of circle formula to solve our given problem.

Circumference = pi*d , where, D represents diameter of circle.

Now, we will set the product of n and circumference of circle equal to 63360 inches as:

pi*22*n= 63360

a) calculate the length of QR
b) calculate the area of trapezium PQRS.
Thanks for helping.​

Answers

Using the given information, length of QR = 16.6 cm

The area of the trapezium is 304.5 cm²

Calculating area of a trapezium

From the question we are to calculate the length of QR and the area of trapezium PQRS

In the given diagram,

Let the midpoint of PS be T

Then, we can write that

|OP|² = |OT|² + |PT|²  (Pythagorean theorem)

|OP| = radius = 13 cm

|PT| = 1/2 × PS = 1/2 × 24 cm = 12 cm

∴ 13² = |OT|² + 12²

169 = |OT|² + 144

|OT|² = 169 -144

|OT|² = 25

|OT| = √25

|OT| = 5 cm

Also, let the midpoint of QR be U

Then, we can write that

|OQ|² = |OU|² + |QU|² (Pythagorean theorem)

|OQ| = radius = 13 cm

From the given information,

The distance of QR from O is twice the distance of PS from O

∴ |OU| = 2 × |OT|= 2 × 5 cm = 10cm

Thus,

13² = ||² + 12²

169 = 10² + |QU|²

|QU|² = 169 -100

|QU|² = 69

|QU| = √69

|QU| = 8.3 cm

Now,

Length of QR = 2 × |QU| = 2 × 8.3 cm

Length of QR = 16.6 cm

b)

Area of the trapezium = 1/2(|QR| + |PS|) × |TU|

Area of the trapezium = 1/2(16.6 + 24) × 15

NOTE: |TU| = |OT| + |OU|

Area of the trapezium = 1/2(40.6) × 15

Area of the trapezium = 20.3 × 15

Area of the trapezium = 304.5 cm²

Hence, the area of the trapezium is 304.5 cm²

When a number is divided b 7, the quotient is 247 and the rimainder is 3,what is the number

Answers

The number, which on divided by 7 gives a quotient of 247 and a remainder of 3 is 1732. Computed using linear equations.

In the question, we are informed that a number when divided by 7, gives a quotient of 247 and a remainder of 3.

Assuming the number to be x.

We can say that x is our dividend, 7 is the divisor, 247 is the quotient, and 3 is the remainder.

The division algorithm equation is:

Dividend = Divisor*Quotient + Remainder,

Substituting values in this equation, we get a linear equation:

x = 7*247 + 3.

To solve for the unknown number x, we solve the equation as follows:

x = 7*247 + 3,

or, x = 1729 + 3,

or, x = 1732.

Thus, the number, which on divided by 7 gives a quotient of 247 and a remainder of 3 is 1732. Computed using linear equations.

In the grocery store, a trolley can hold 20 lbs of groceries. annie put 12 lbs 8 oz of groceries on the trolley. how much more weight can the trolley hold ?

Answers

7 lbs 8 oz more weight can the trolley hold the trolley can hold 20 lbs of groceries and Annie put 12 lbs 8 oz of groceries on the trolley. This can be obtained by converting the values to oz and subtracting them.

How much more weight can the trolley hold ?

We know that, 1 lbs = 16 oz

Capacity of the trolley = 20 lbs

                                     = 20 × 16 oz

                                     = 320 oz

Weight put in the trolley = 12 lbs 8 oz

                                        = ( 12 × 16 ) + 8 oz  

                                        = 192+8 oz

                                        = 200 oz

Remaining weight that the trolley can hold = 320 oz - 200 oz

                                                                       = 120 oz

                                                                       = (7 × 16) + 8 oz

                                                                       = 7 lbs 8 oz

Hence 7 lbs 8 oz more weight can the trolley hold the trolley can hold 20 lbs of groceries and Annie put 12 lbs 8 oz of groceries on the trolley.

Then,

74° + y + y = 180° (Sum of angles in a triangle)

74° + 2y = 180°

2y = 180° - 74°

Jun wei has 12 more 10 cents coins than 20 cents coins. the total value of all the coins is $5.40. find the total number of coins he has.

Answers

Jun Wei has a total of 40 coins. An algebraic expression or equation with the given information is formed to calculate the total number of coins.

What is an algebraic expression?

An algebraic expression is the combination of one or more variables, coefficients, and constants separated by operators. Each of them is called terms of the expression.

Eg: a + 6x + 5y + 2

Here there are 4 terms with 3 variables, 3 coefficients, and one constant.

Calculation:

Given that,

Jun Wei has 12 more 10 cents coins than 20 cents coins.

So,

Consider the number of 20-cent coins = x

Then, the number of 10 cent coins = x + 12

It is given that the total value of all the coins is $5.40.

Where 1 $ = 100 cents. That implies, $5.40 = 540 cents

So,

the total value of the coins = 540 cents

⇒ 20(x) + 10(x + 12) = 540

⇒ 30x = 540 - 120

⇒ 30x = 420

∴ x = 40

Hence, there are 40 coins with Jun Wei.

What is p ÷ r equal to?
tan x°
tan y°
sin y°
cos x°

Answers

Answer: tan x

Step-by-step explanation: An angle determines if a side is opposite the angle, or adjacent the angle. Since p/a is something to do with the tangent, as it is not using the hypotenuse (the longest side.) Tangent is Opposite/Adjacent, while Sine is Opposite/Hypotenuse and Cosine is Adjacent/Hypotenuse. The only thing that makes sense is tangent.

So, that leaves us with either tan y or tan x. Well, with x, the angle that x points to (which is the opposite side) is p, and the adjacent is a, so p/a must be Tangent(x) since it is Opposite/Adjacent sides.

Only if it was r/p would it be tan y, since r becomes the opposite and p becomes the adjacent.
