Answer:Here, a=3, b=-10 and c=2. Substitute the values, Therefore, the discriminant of is 76.

Step-by-step explanation:

The Venn diagram of each situation is a diagrammatic way of representing what the situation stands for

Diagram 1: A ∩ B ∩ C

This means that we shade all intersection points of the sets A, B and C

Diagram 2: (A ∩ B) ∪ C

This means that we shade the intersection points of the sets A and B and the whole of set C

Diagram 3: A ∩ (B ∪ C)

This means that we shade the where the set A intersects with the whole of sets B and C

Diagram 4: (A ∩ B) \ C

This means that we shade the intersection point of the sets A and B without shading any point on set C

Diagram 5: (A\B) ∪ (B\C) ∪ (A\C)

This means that we shade all set A without set B, all set B without set C and all set A without set C. In other words, we shade everything in the set without shading set C

I am going to assume that leg a:

  ⇒ is the horizontal distance between the house and the gas station

     ⇒ Distance for leg a: 6 miles

I am also going to assume that leg b

  ⇒ is the vertical distance between the house and gas station

Answer:

rate of change:

y-intercept:

Step-by-step explanation:

your equation is y=3.25x+30

Here, the y-intercept is 30

your rate of change is $3.25, since you get charged $3.25 per bouquet.

The rate of change is $3.25 and the y-intercept is $30.

A mathematical statement that relates two algebraic expressions by an equal sign.

The Tram fancy balloons has offered a down payment of $30

and the charge per bouquet is $3.25

Let x represent the number of bouquets

The equation for the total cost can be formed is

y = 30 + 3.25*x

On comparing this with the standard equation y =mx+c

Here m is the slope and the rate of change and c is the y intercept

So,

The rate of change is $3.25

the y-intercept is $30

Therefore, the rate of change is $3.25 and the y-intercept is $30.

The perimeter of the water wheel  [tex]8\sqrt{10}[/tex]

The correct option is (A)

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. To derive the formula, let us consider two points in 2D plane A( x, a) and B(y, b).

So, the distance between two points be: [tex]\sqrt{(y-x)^{2}+(b-a)^{2}}[/tex]

As water wheel is designed in the shape of regular octagon.

To find the perimeter of the  water wheel.

Since the water wheel is in the shape of regular octagon all sides are equal.

Using Distance Formula,

D= [tex]\sqrt{(4-3)^{2}+(0-3)^{2}}[/tex]

  = [tex]\sqrt{10}[/tex]

So, the side of regular octagon will be [tex]\sqrt{10}[/tex].

Perimeter of Regular Octagon = 8 x side

                                                   = [tex]8\sqrt{10}[/tex]

Hence, the perimeter of the water wheel  [tex]8\sqrt{10}[/tex]

Answer:

A

Step-by-step explanation:

Answer:

x = 27

Step-by-step explanation:

because the angles are on a line that means they add up to 180

18 + x + 5x = 180

then combine like terms

18 + 6x = 180

then you subtract 18 from both sides

6x = 162

lastly divide both sides by 6

x = 27

I believe it’s C, convert 0.188 into a fraction

Answer:

x = -1/2.

Step-by-step explanation:

x^2 - 4 = (x - 2)(x + 2)  so if we multiply each term by x^2 -4 we get:

2 - 1(x - 2) = 3(x + 2)

2 - x + 2 = 3x + 6

2 + 2 - 6 = 3x + x

4x = -2

x = -1/2.

Answer:

[tex]-\frac{1}{2}[/tex]

Step-by-step explanation:

1. Multiply both sides of the equation by the LCM (x - 2)(x + 2):

[tex]\frac{2}{x^{2} -4} (x-2)(x+2)[/tex]

factor x² - 4 by rewriting it as x² - 2²

x² - 2² = (x + 2)(x - 2)

now we have;

[tex]\frac{2}{(x+2)(x-2)} (x-2)(x+2)[/tex]

cancel the common factors (x - 2)(x + 2)

= 2

-------------------------------

[tex]\frac{-1}{x+2} (x-2)(x+2)[/tex]

cross cancel the common factor (x + 2)

[tex]\frac{-1}{x-2}=-(x-2)=-x+2[/tex]

-------------------------------

[tex]\frac{3}{x-2} (x-2)(x+2)[/tex]

cross cancel the common factor (x - 2)

3(x + 2)

distribute the 3

3x + 6

-------------------------------

combining all new values, we have;

2 + (-x) + 2 = 3x + 6

-x + 4 = 3x + 6

2. Isolate x:

-x + 4-4 = 3x + 6-4

-x = 3x + 2

-x-3x = 3x-3x + 2

-4x = 2

-4x/-4 = 2/-4

The surface area of the barn is 2040 square feet.

A rectangle is a plane shape with four sides and four right angles.

Analysis:

The barn is composed of:

Two straight  long rectangles with dimensions = 10ft x 40ft

Two slant rectangles with dimensions = 10.6ft x 40ft

Two short rectangles with dimensions = 10ft x 14ft

Two triangles, height 8ft and base 14feet

The surface area of barn = 2(10x40) + 2(10.6 x 40) + 2(1/2 x 14 x 8) + 2(10 x 40) = 800 + 848 + 112 + 280 = 2040 square feet

The domain of the inverse of the function f(x) = 5e^x + 3 is found being all real numbers > 3. Or, we can write this symbolically as: D( f^(-1)(x)) = (3,∞)

Domain is the set of values for which the given function is defined.

Range is the set of all values which the given function can output.

Suppose that the given function is

[tex]f:X\rightarrow Y[/tex]

Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is

[tex]f^{-1}: Y \rightarrow X[/tex]

such that:

[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]

(and vice versa).

It simply means, inverse of 'f' is undo operator, that takes back the effect of 'f'

The domain of the inverse of a function (if it exists) is the range of the function it is inverse of. Similarly range of the inverse of that considered function is the domain of that considered function.

The function given is:

[tex]f(x) = 5e^x + 3[/tex]

The domain of the inverse of this function is this function's range.

Assuming only real values are allowed, for any real number x, we have:

[tex]e^x > 0[/tex]

And therefore, we get:

[tex]5e^x > 0 \: \forall x \in \mathbb R\\5e^x + 3 > 3 \: \forall x \in \mathbb R\\[/tex]

Also, since the function [tex]f(x) = 5e^x + 3[/tex] is strictly monotonically increasing and continuous, it touches all the values as its output from any real number > 3 till any finitely large number.

Thus, its range is (3, ∞) (it is an interval consisting of all the real numbers > 3)

This is the domain of its inverse function.

Thus, the domain of the inverse of the function f(x) = 5e^x + 3 is found being set of all real numbers > 3. Or, we can write this symbolically as: D( f^(-1)(x)) = (3,∞)

Using an exponential function, it is found that it takes 5.42 years for the car to halve in value.

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

In this problem, the car depreciates 12% a year in value, hence r = 0.12 and the equation is given by:

[tex]A(t) = A(0)(0.88)^t[/tex].

It halves in value at t years, for which A(t) = 0.5A(0), hence:

[tex]A(t) = A(0)(0.88)^t[/tex]

[tex]0.5A(0) = A(0)(0.88)^t[/tex]

[tex](0.88)^t = 0.5[/tex]

[tex]\log{(0.88)^t} = \log{0.5}[/tex]
