Explanation:
The point (9,8) is in the original set of ordered pairs.
We cannot include (9,-8) since x = 9 is already listed. We can't have repeated x values. If x repeats, then we don't have a function.
This rules out choice A.
Choices B and D are eliminated for similar reasoning.
Choice C can be included because x = -9 hasn't been mentioned yet.
Note: A function is when any given x value leads to exactly one y value.

the bill at an electronics store was $52 before tax.
tax is 5 percent. what is the total price with tax?
Answer:
$54.6
Step-by-step explanation:
To solve the question, we need to find how much 5% of 52 is
For questions where we need to calculate the percentage, we will multiply the number by given percentage and then divide it by the whole, 100%
52*5/100 = 2.6
Now the price before the tax was 52 and the tax is 2.6
the total price:
2.6 + 52 = 54.6

Which shape should the landscape architect recommend to a client who wants the largest possible area for an 80-foot rope?
A.
Square
B.

Answer: The area of the square is 400sqf.
Answer 2: Area of circle = 509.31 square feet.
Answer 3: The circle because the circle's are is larger
Answers:
Area of the square = 400 square feetArea of the circle = 509 square feetRecommended shape with largest area = Circle==========================================================
Explanation:
The rope forms the perimeter of each shape. This is the distance around the outer edges.
The square has all four sides the same length. Since we have 80 feet of rope, each side must be 80/4 = 20 feet long.
The area of the square is 20*20 = 400 square feet.
--------------
The circle has a circumference of 80 feet, which leads to a radius of...
C = 2*pi*r
r = C/(2pi)
r = 80/(2pi)
r = 12.732395
which is approximate. I used my calculator's stored version of pi so I could get the most accuracy possible.
Then use this to find the area of the circle
A = pi*r^2
A = pi*(12.732395)^2
A = 509.295782
This value is also approximate.
When rounding to the nearest whole number, we get A = 509
The area of the circle is about 509 square feet.
The circle has the largest area.

Answer:
Answer = 157
Step-by-step explanation:
The formula to finding the volume of a cone is h(pi)(r^2)/3. We know that the height is 6 and the base is 10. This means that the radius is 5 because it is 1/2 of the base. Now we plug in our numbers into the equation and get 157!

A triangle has a base of 8 cm and a height of 12 cm.
What is the area of the triangle?
Enter your answer in the box.
*box* cm2
Answer: 48 cm^2
Step-by-step explanation:
The equation for the area of a triangle is 1/2(base*height). Plug in the numbers to get an equation of 1/2(8*12). 8*12 = 96. Now divide by 2. 96/2 = 48.
Answer:
48 cm^2
Step-by-step explanation:
a triangle area is hb/2
so 8*12=96
96/2=48 therefore 48 is the answer.

Let's take a look at our problem, it says we need to find the perimeter of the rectangle; luckily, we have all the info we need!
This is the perimeter formula:
⇒[tex]\frak{Perimeter_{rectangle}=2(a+b)}[/tex]
So basically, it says we need to take the rectangle's length (a), add it's width (b), and multiply their sum times two, and this is equal to the perimeter.
The problem tells us that:
⇒ Length 5x+5
⇒ Width 2x-1
As the equation says, we should add the length and the width:
⇒ 5x+5+2x-1
⇒5x+2x+5-1
⇒7x+4
· Hooray! We found the perimeter!
× Actually, we didn't find the perimeter, yet! Remember, we also need to multiply by 2.
Multiplication results in
⇒ 2(7x+4)
expanding the expression
⇒14x+8
· Now we did find the perimeter, and what's more, we've written it in simplest form.
