Answer 1

Answer:

-q^2-q+72

Step-by-step explanation:

We can use the FOIL (First Outer Inner Last) method for this. First, multiply 9*8 (72). Then, multiply 9*-q(-9q). After that, multiply q*8 (8q). Finally, multiply q*-q(-q^2). Arrange the different terms:

-q^2-9q+8q+72

Finally, combine like terms:

-q^2-q+72

What is Sequence?

A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

Here, given points;

                            x₁ = 1 , x₂ = 2 and y₁ = -3.75 , y₂ = -4.5

Now,

    d = (y₂ - y₁)/(x₂-x₁)

    d = (-4.5 - (-3.75))/(2 - 1)

     d = -0.75 / 1

     d = - 75/100

      d = -3/4

Thus, The correct option is option B.  The common difference between given data is -3/4.

Hello!

The missing angle is 60°, and is found by subtracting 90° and 30° from 180°.

Using basic triangle theorems of a 30° - 60° - 90° triangle, we know that the leg opposite to 30°, x, is one-half of the hypotenuse.

So:x = 0.5(12)x = 6.

The value of x is 6.

The leg opposite to 60° is √3 times the leg opposite to 30°.

The slope of the  line passing through the points (3, 3) and (0, -6) is 3.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

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

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We need to find the slope of line passing through points (3, 3) and (0, -6)

Plug in the values in formula.

m=-6-3/0-3

m=-9/-3

m=3

Hence, the slope of the  line passing through the points (3, 3) and (0, -6) is 3.

Answers

Answer:

B. (2, 4)

Explanation:

Given equations:

a) y = x + 2

b) y = 3x – 2

Solve them simultaneously:

x + 2 = 3x – 2

x - 3x = -2 - 2

-2x = -4

x = 2

Then find y = x + 2 = 2 + 2 = 4

Solution: (x, y) = (2, 4)

Answer:

(2,4)

Step-by-step explanation:

substitute the value of y x+2 = 3x-2

solve the value of x  x = 2

substitue the value of x into one of the equations y = 2+2

solve for y value y = 4

Mark is solving an equation where one side is a quadratic expression and the other side is a linear expression. He sets the expressions equal to y and graphs the equations. What is the greasiest possible number of intersections for these graphs?

Answers

The greasiest possible number of intersections for these graphs is 2 if the Mark is solving an equation where one side is a quadratic expression and the other side is a linear expression.

What is a quadratic equation ?

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

As we know the standard form of a quadratic equation is:

[tex]\rm Y = \rm ax^2+bx+c[/tex]

And a linear equation can be written as:

y = mx + d

Equating both the expression:

ax² + bx + c = mx + d

ax² + (b-m)x + c - d = 0

The above equation is an also quadratic equation, and we know that the quadratic equation have maximum two roots.

Thus, the greasiest possible number of intersections for these graphs is 2 if the Mark is solving an equation where one side is a quadratic expression and the other side is a linear expression.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that the roof of a clock tower is a pentagonal pyramid.

a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point

Each side of the base is 7 ft long.

The slant height is 9 ft.

The equation x = 7 - 4√3 is a radical expression, and the value of the radical expression is [tex](x + \frac 1x)^2 = 3650401 -2107560\sqrt 3[/tex]

How to solve the expressions?

The equation is given as:

x = 7 - 4√3

So, we have:

[tex](x + \frac 1x)^2 = (7 - 4\sqrt 3 + \frac{1}{7 - 4\sqrt 3})^2[/tex]

Take the LCM

[tex](x + \frac 1x)^2 = (\frac{49 -56\sqrt3 + 48}{7 - 4\sqrt 3})^2[/tex]

Evaluate the like terms

[tex](x + \frac 1x)^2 = (\frac{97 -56\sqrt3 }{7 - 4\sqrt 3})^2[/tex]

Rationalize

[tex](x + \frac 1x)^2 = (\frac{(97 -56\sqrt3)(7 - 4\sqrt 3) }{49 -48})^2[/tex]

Evaluate the difference

[tex](x + \frac 1x)^2 = ((97 -56\sqrt3)(7 - 4\sqrt 3))^2[/tex]

$75 before tax. Disc: 10% Tax: 7%, Tip: 20% what's the total PLEASE help

Answers

Answer:

  total: $86.68

Step-by-step explanation:

The value of each change is found by multiplying the base amount by the percentage change. The result is rounded to the nearest cent. Here, we're applying 3 changes. In order to make sure they're rounded properly, we need to apply them in order

__

discount

The discount amount is ...

  discount = bill × 10% = $75.00 × 0.10 = $7.50

The discounted amount is ...

  bill - discount = $75.00 -7.50 = $67.50

__

tax

The tax amount is ...

  tax = discounted bill × tax rate = $67.50 × 0.07 = $4.725 ≈ $4.73

The bill with tax added is ...

  discounted bill + tax = $67.50 +4.73 = $72.23

__

tip

The tip is apparently added to the amount after tax, so the amount of the tip is ...

  tip = taxed bill × 0.20 = $72.23 × 0.20 = $14.446 ≈ $14.45

The bill with tax and tip added is ...

  total bill = $72.23 +14.45 = $86.68

_____

Additional comment

At each stage, the amount can be found by using the multiplying factor (1+p), where p is the percentage change. All three factors applied gives a result of ...

  75×(1-0.10)(1+0.07)(1+0.20) = 75×0.9×1.07×1.2 = 86.67

You will note this differs by a penny from the amount calculated above. That is a consequence of rounding up both the tax and the tip.
