Answer:
Answer will be 1/53 as a fraction, and 0.02 as a decimal.
Step-by-step explanation:
In order to solve this equation, we will first plug in -8 into every x term.
So now we will have:
[tex]f( - 8) = \frac{1}{ - 8 {}^{2} - 11 } [/tex]
{Don't mind the f (-8), just think of it as a sort of place holder.}
Anyways, now we will do -8 × -8, since that's what -8^2 implies:
-8 × -8 = 64
Next do 64 - 11, to get 53.
Now we have 1/53
(You can also divide the numerator by the denominator, to get the answer in decimal form.)
Hope this helps you :)
Sorry if it doesn't.

Step-by-step explanation:
In Freeport, Illinois, Empire Street runs east to west and route 26 runs north to south.
Zippy’s Pizza parlor is located on route 26, 3 miles south of Empire street.
Zippy’s advertises that it delivers within a 4 mile radius.
Write an equation that represents the radius of delivery for Zippy’s Pizza. Assume that Zippy’s is located at the origin.
- How far east and west from route 26 can you live on Empire street and still receive Zippy’s Pizza delivery?
- Little Cubs Field is located 2 miles west and 4 miles north of Zippy’s. How far is Little Cubs Field from Zippy’s?
- How far is Little Cubs Field from the radius of delivery?
Answers
The area to which Zippy's Pizza makes delivery is 16·π square miles
The responses are;
First Part: x² + y² = 4²Second Part: √5 miles east and √5 miles west from route 26Third Part: 2·√5 milesFourth Part: 2·(√5 - 2) milesReasons:
The radius of the area that Zippy delivers pizza = 4 miles
Direction in which Empire Street runs = East to west
Direction of the route 26 route = North to south
Location of Zippy's Pizza parlor = 3 miles south of Empire street
-First Part:
The equation that represents the radius of delivery for Zippy's Pizza is given by the equation of a circle as follows;
(x - h)²+ (y - k) = r²
Where:
(h, k) = The center of the circle which is the location of Zippy's Pizza
r = The radius of the circle
Zippy's Pizza is at the center of the circular area with coordinates (h, k) = (0, 0)
r = 4 miles
-Which gives;
(x - 0)² + (y - 0)² = 4²
The equation that represent the radius is; x² + y² = 4²
-Second part:
The locations of addresses on Empire street, relative to Zippy's Pizza are given by the equation;
y = 3
Therefore, we have;
The furthest distances east and west on Empire street that can receive Zippy's Pizza delivery are given by the equation;
x² + 3² = 4²
x = √(4² - 3²) = ±√5
The furthest distances that can receive Zippy's Pizza delivery are ±√5 miles (east and west) from route 26
-Third Part:
Location of Little Cubs = 2 miles west and 4 miles north of Zippy's
The distance from Little Cubs Field to Zippy's = √((2² + 4²) = 2·√5
The distance from Little Cubs Field to Zippy's = 2·√5 miles
-Fourth Part:
The distance between Little Cubs Field from Zippy's radius of delivery, d, is found as follows;
d = 2·√5 - 4 = 2·(√5 - 2)
Therefore, d = 2·(√5 - 2) miles

Which expression tells how much greater the temperature change was on Friday than on Saturday?
Answers
Option B
Temperature change on Friday=81-72Temperature change on Saturday=76-69Total difference
[tex]\\ \rm\Rrightarrow (81-72)-(76-69)[/tex]
The correct expression is (81 - 72) - (76 - 69).
Option 2 is correct.
What is Arithmetic?The study and use of numbers, their relationships, and mathematical observations are topics covered by the area of mathematics known as arithmetic. The fundamental ideas in number theory, measurement, and computation are frequently referred to as "arithmetic" (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).
As per the given data:
The high and low temperature for Friday and Saturday is given in the table.
Temperature change = High Temperature - Low Temperature
To find the expression which tells how much greater the temperature change was on Friday than on Saturday:
= Temperature change on Friday - Temperature change on Saturday
= (81 - 72) - (76 - 69)
Hence, the correct expression is (81 - 72) - (76 - 69)

The area of a rectangle is 3/4 square yards. If the width of the rectangle is 3/5, what is the length?
JUST TELL ME HOW TO FIND THE ANSWER
Answers
Answer:
Divide 3/4 by 3/5 to get 1 1/4.
Step-by-step explanation:
To find area, you multiply the length by the width. However, they gave you the area and the width. Therefore, you divide the width by the area (I think).
3/4 divided by 3/5 = 1 1/4
The length is 1 1/4.

The table shows the approximate height of a football after it is kicked. Tell whether the rates of change for successive time intervals are constant or variable.
Answers
Answer:
36, 14, -12
variable
Step-by-step explanation:
1st Rate of change is 18 - 0 / 0.5 - 0 = 18/0.5 = 36
2nd rate of change is 32 - 18 / 1.5 -0.5 = 14 / 1 = 14
3rd rate of change is 26 - 32 / 2 - 1.5 = -6/0.5 = -12
so the rates of change are variable

Slope is 1/3
Step-by-step explanation:
This is because the line is positive (moving upwards), and it moves up 1 unit and to the right 3 units. That means if you write it in the form of rise/run, where rise is the up or down movement and run is the left or right movement, 1 will be on top and 3 will be at the bottom.
Bonus: The line is y = 1/3x -5 (where 1/3 is slope and -5 is the y-intercept).
