Please do it fast!

Step-by-step explanation:

so, this is a multiplication ?

6 3/4 × (-11.5)

let's bring the mixed numbers to full fractions, and then we can easily multiply.

6 3/4 = (6×4 + 3)/4 = (24 + 3)/4 = 27/4

-11.5 = -11 1/2 = (-11×2 - 1)/2 = (-22 - 1)/2 = -23/2

so, the multiplication is

27/4 × -23/2 = 27×-23 / 4×2 = -621/8 =

= (-616 - 5)/8 = (-77×8 - 5)/8 = -77 5/8

Answer:

-77 5/8

Step-by-step explanation:

6 3/4 can be turned into 6.75.

6.75 * -11.5 is -77.625

-77.625 can be simplified into 5/8

First, we will need to convert  9 foot to yards as shown;

9 foot = 3 yards

This shows that a 3 yard piece of ribbon costs $20.07, the price per yard is expressed as;

Price per yard = 20.07/Total yard

Price per yard = 20.07/3

Price per yard = 6.69

The polynomial is twice the sum of -2x² + 5x - 3 and 5x² - 4 is 6x² + 10x - 14.

Given the polynomials in the question;

-2x² + 5x - 3 and 5x² - 4

First, we find the sum of the polynomials

(-2x² + 5x - 3) + (5x² - 4)

A location that is 30 degrees north and 45 degrees west is west of the prime meridian and north of the equator.

A prime meridian refers to an arbitrary meridian which is there in a geographic coordinate system. Here, the longitude is defined as 0°.

A prime meridian and its anti-meridian will together form a great circle in a geographic coordinate system.

The Equator is a circle of latitude, about 40,075 km in circumference, that divides Earth into the Northern and Southern hemispheres.

It is an imaginary line that is located at 0 degrees latitude, and is a halfway between the North and South poles.

He have to pay $3.25.

Let the number of miles traveled by a driver be x

The toll paid by the driver is then represented as y. (in dollar)

Linear equation : an equation in which there is only one variable present. It is of the form Ax + B = 0, where A and B are any two real numbers and x is an unknown variable that has only one solution.

Since there is a linear relation between the two, we can assume the equation can be written as:

y = mx + c

From the given data, we get

0.24 = m(0) + c

c = 0.25

Using the second point:

1 = m(1) + 0.25

m = 1 − 0.25 = 0.75

Hence, the equation is y = 0.75x + 0.25.

If  x = 4, then:

y = 0.75 × 4 + 0.25

y = 5.50

The value of csc x=-13/5.

Given that the sin x=-5/13 and x∈[3π/2 , 2π).

A trigonometric function is a real function that relates the angle of a right triangle to the ratio of the lengths of the two sides. The basic functions are sin, cos, tan, cot, sec, csc.

The given function is sin x=-5/13.

As we all know that sin x=1/csc x or csc x=1/sin x.

As it is given that x∈[3π/2 , 2π) that means x lies in fourth quadrant and in fourth quadrant sin and csc is negative in it.

So, we will apply this identity csc x=1/sin x, we get

csc x=1/(-5/13)

csc x=-13/5

And it also lies in x∈[3π/2 , 2π).

Hence, the value of csc x when sin x=-5/13 and x∈[3π/2 , 2π) is csc x=-13/5.

Answer:

Step-by-step explanation:

The total number of different outcomes when rolling 4 dice is

6 × 6 × 6 × 6 = 1296

The possible number of outcomes of rolling a 6 followed by 3 odd numbers is

1 × 3 × 3 × 3 = 27

p(6 followed by 3 odd numbers) = 27/1296 = 1/48

The solution of the simultaneous equations are x = 2, 3 and y = 3,9.

In mathematics; a set of simultaneous equations, also known as a system of equations or an equation system, it is a finite set of equations for which common solutions are sought.

WE have given simultaneous equations as;

y = x^2    ...(i)

y = x + 6  .....(ii)

Now Equating (i) and (ii) we get,

x^2 = x + 6

or, x^2 - x - 6 = 0

Then Solving we get;

x^2 - 3x - 2x - 6 = 0

x(x - 3) -2(x - 3) = 0

(x - 2)(x - 3) = 0

So, x = 2, 3

Now Putting x = 2, 3 in equation (i) we get;

y = 2^2

y = 4

and,

y = 3^2

y = 9

Thus, y = 3,9

Hence the solution of the simultaneous equations are x = 2, 3 and y = 3,9.

Domain: (-∞, ∞)

Range: (-∞, ∞)

Domain and range help us describe the values a graph covers.

Defining Domain and Range

Remember that the x-values are along the horizontal axis, and the y-values are on the vertical axis.

The function given to us extends infinitely to the left and right as shown by the arrows. Additionally, the graph extends up and down infinitely; thus the range is also infinite.

Interval Notation

Interval notation should be written as (minimum value, maximum value). If the minimum and maximum values are included within the range or domain, then the parentheses should be replaced with brackets. This looks like [included minimum, included maximum]. Since a function cannot actually include infinity, an infinity symbol should never have brackets.

Eventually, this linear function will reach every single x and y-value in existence. So, both axes have a minimum of -∞ and a maximum of ∞. Thus, both the domain and range are (-∞, ∞).

Hint for future problems: all linear functions will have a domain and range of (-∞, ∞).

Yes, it is true that if "x" is an optimal solution to a linear programming problem, then it is a vertex of the feasible region.

The coordinates of A'' will be ( -2, 5).

We are given that:

Quadrilateral ABCD is reflected across the x - axis.

We know that, when a refection is done about x-axis, the values of the abscissa x remain identical & the value of ordinate  just change their signs:

A(-5,-3) will become A'(-5,+3)

B(-6,-1) will become B'(-6,+1)

C(-3,-1) will become C'(-3,+1)

D(-2,-3) will become D'(-2,+3)

Now, the reflected quadrilateral A'B'C'D' is then translated 3 units right and 2 units up to form quadrilateral A"B"C"D".

So, the coordinates of A'' will become:

Final answer: P=(1,5)

Step-by-step explanation:

The line APB is a line such that AP/PB= 1/3. From the points A and B that we have we can find the distance between those points using the formula d= [(y2-y1)^2=(x2-x1)^2]^1/2

d= 4 (13)^(1/2)

Now the ratio is 1:3. AP= sq rt(13) and PB= 3 sq rt(13)

Using mid point formula the mid point of AB (say Q) = [(-1+7)/2,(2+14)/2]= (3,8).

Hence the mid point of AQ is P which can found out again using the mid point formula

P= [(-1+3)/2,(2+8)/2]= (1,5)
