Answer:

So, the coefficient of the x^2 -term is 80

Step-by-step explanation:

so we need to simplify it:

#10(x^2)(2^3) = 10(x^2)(8) = 80x^2

Answer:

Step-by-step explanation:

Find the center, the midpoint of the diameter:

Find the square of the radius by distance formula:

Equation of the circle:

Substitute the values to get:

Answer:

solution given:

points at (4, -3) and (-2, 5

diameter [d]=

[tex]d = \sqrt{(4 + 2) {}^{2} +( - 3 - 5) {}^{2} } \\ d = 10units \\ radius(r) = 5units [/tex]

centre[h,k]={(4-2)/2,(-3+5)/2}=(1,1)

now equation of a circle

(x-h)²+(y-k)²=r²

(x-1)²+(y-1)²=25 is a required equation

Answer:

The area of the lawn that is covered by the water from the  sprinkler is

[tex]125.6[/tex] square meter

Step-by-step explanation:

Given

The radius of the circle is 12 m

Area of the circle is [tex]\pi r^2 = \pi * 12^2 = 144\pi[/tex]

For one complete circle,  the degree of rotation is 360 degrees.

Area of lawn covered by rotation of 100 degrees only is 100/360 = 5/18

The area of the lawn that is covered by the water from the  sprinkler is

[tex]\frac{5}{18} * 3.14*144 = 125.6[/tex] square meter

Answer:

x > -6

Step-by-step explanation:

Answer:

Susan spilled 1/6 of a gallon of lemonade.

Step-by-step explanation:

Since Susan was carrying a pitcher that contained 2/3 of a gallon of lemonade to the table for lunch, and she slipped and spilled 1/4 of the lemonade in the pitcher, to determine what fraction of a gallon of lemonade did she spill the following calculation must be performed:

2/3 = 0.6666

0.666666 x 1/4 = X

0.166666 = X

0.166666 = 1/6

Therefore, Susan spilled 1/6 of a gallon of lemonade.

Answer:

The room is 14ft high

Step-by-step explanation:

Given

[tex]Volume = 2016ft^3[/tex]

[tex]Base\ Area = 144ft^2[/tex]

Required

The height of the room

This is calculated as:

[tex]Volume = Base\ Area * Height[/tex]

Make Height the subject

[tex]Height = \frac{Volume}{Base\ Area}[/tex]

So, we have:

[tex]Height = \frac{2016ft^3}{144ft^2}[/tex]

[tex]Height = \frac{2016}{144}ft[/tex]

[tex]Height = 14ft[/tex]

Answer:

Th final equation is [tex]Y = 2X^2 -3[/tex]

The graph is attached

Step-by-step explanation:

Given

[tex]X = \sqrt{t} \\t = X^2[/tex] --- Eq (1)

and [tex]Y = 2t -3[/tex] --- Eq (2)

Substituting the value of "t" from Eq (1) into Eq (2), we get -

[tex]Y = 2X^2 -3[/tex]

The graph for the equation is attached here with

The Cartesian form of the parametric equation is y = 2x² – 3 and the graph will be a parabola.

A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.

We have parametric functions:

x = √t ⇒ x² = t

y = 2t—3

Plug t = x² in the other equation, we get:

y = 2x² - 3

The graph will be a parabola.

Thus, the Cartesian form of the parametric equation is y = 2x² – 3 and the graph will be a parabola.

Answer:36.7

Step-by-step explanation:

Answer:

Answer is E but not 100%

Step-by-step explanation:

Answer:

A is correct

E shows an error as the first two values are identical so one cannot be greater than the other.

Step-by-step explanation:

A shows 2.69 is equal to 2.696 which is more than 2.696 which is more than 2.696 which is more than 2.696

As when;

2.696 repeats in bold = 2.696969696  1st greatest

2.696 repeats in bold = 2.696696696 2nd in highest value so 2nd in order.

2.696 repeats in bold = 2.696666666 3rd in highest value so 3rd in order.

2.696 does not repeat = 2.696 so is the least greatest from the list.

Or 13 with a remainder of 5

13R5

or

13 5/8

The quotient is 13 and the remainder is 4 for the given statement.

When we divide 108 by 8, we find:

108 ÷ 8 = 13 remainder 4

The quotient is 13 and the remainder is 4.

Therefore, 108 divided by 8 is equal to 13 with a remainder of 4.
