PLEASEE HELPPP!!!!
the total land area of australia is about 8,000,000 km^2 , or 8 × 10^6 km^2.
the total land of new york city is about 800 km 2, or 8 × 10^2 km^2.
About how many times larger is australia than new york city?
A. 7,999,200
B. 4 times
C. 1 × 10^4 times
D. 1 × 10^-4 times
Answer:
C. 1 × 10^4 times
Step-by-step explanation:
Australia= 8 × 10^6 km^2
New york= 8 × 10^2 km^2
easy
look at the exponents when you divide them they subtract
(8 × 10^6 km^2)/(8 × 10^2 km^2)
6-2=4
8/8=1
1*10^4
8000000
/800
10000
or
1*10^4

1. Is the relation a function and why or why not?
{(1, 2), (2, 3), (1, 6), (4,3)}
Answer:
Its not a function, D
Step-by-step explanation:
its not a function because the x value, 1, repeats. input is x and output is y, so the input of 1 has more than one output.

What is the distance between the points (1,4) and (3,7)
Answer:
[tex]2\sqrt{10}[/tex]
Step-by-step explanation:
To find the distance between points, we can use the following formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2 }[/tex]
We have two coordinates; (1, 4) and (3, 7)
Let's plug these values into the equation
[tex]d = \sqrt{(3 - 1)^2 + (7 - 1)^2} = 2\sqrt{10}[/tex]
Good luck!
Given X = {15, 22, 33, 44, 89, 165, 1025} and Y = {-5, 15, 33, 88, 99, 150, 160, 1025}, which of the following statements is false?
Ø (X Y)
X Y = {-5, 15, 22, 33, 44, 89, 99, 150, 160, 165, 1025}
X ∩ Y = {15, 33, 1025}
WHAT EVEN IS THIS LOL
Answer:
the first one
Step-by-step explanation:
in the first one it says there are no common numbers between x and y which is false.
in the second one its the union of x and y which means that you must list all numbers in x and y without repetition
the third one states that 15,33,1025 are the only numbers that are common between x and y.
so as a breif the first one is wrong

[tex] {6}^{ - 3} [/tex]
? Select the correct answer.
Answer:
1/216
Step-by-step explanation:
Simplify the following:
6^(-3)
Hint: | In order to evaluate 6^3 express 6^3 as 6×6^2.
6^3 = 6×6^2:
1/(6×6^2)
Hint: | Evaluate 6^2.
6^2 = 36:
1/(6×36)
Hint: | Multiply 6 and 36 together.
6×36 = 216:

Find the area of each sector.
Answer:
d. 250π/3
Step-by-step explanation:
A = πr²
A = 3.14(10)² = 314.159
A = 314.159*(5/6) = 261.799
A = 261.799 = 250π/3
Answer:
D
Step-by-step explanation:
You need to set up a ratio between the area of the sector & the area of the circle vs the angle of the sector & 360 degrees.
[tex]\frac{SectorAngle}{360} =\frac{SectorArea}{CircleArea}[/tex]
That above is your formula you need to remember for these equations.
Now let's solve. You've been given the sector angle, which is 300 degrees, and you've been given the radius of the circle, 10 feet.
The area of a circle is the formula: A = πr²
Given that formula and you know the radius. You plug in 10 feet for r and solve for the area.
[tex]A=\pi10^2\\A=314.159[/tex]
Now lets solve for the missing variable (Sector Area).
[tex]\frac{300}{360} = \frac{x}{100\pi }\\100\pi * \frac{300}{360} = \frac{x}{314.159}*100\pi\\100\pi* \frac{300}{360} = x\\\frac{250\pi }{3} = x[/tex]
I kind of messed up since I didn't realize the answer choices were simplified, make sure for the area you don't completely solve the area, keep the pi simple if the answer choices include pi.
If you shift the linear parent function, f(x) = x, to the left 2 units, what is the
equation of the new function?
it's a horizontal translation so, the equation is f(x) = (x + 5). Whenever you translate to the right it is negative.

Which expression is equivalent to 30 ÷ (3 + x)
A. (3 + x) ÷ 30
B. 30 ÷ (x +3)
C (3÷30) + x
D 30 ÷ 3 + 30 ÷ x
Answer:
Answer would be B because addition is commutative that is, a + b = b + aSo answer would be 30 ÷ (X + 3)
Which expression is equivalent to 5(x - 3y + 4)
A:5x-8y+9
B:1/5x-3/5y+4/4
C:1/5x-3/5y+4/5
D:5x-15y+20
Please respond quick
Answer:
D. 5x-15y+20
Step-by-step explanation:
If you distribute 5 to all the numbers in the parenthesis, you get 5x-15y+20. This is because 5 multiplied by x is 5x, 5 multiplied by 3y is 15y, and 5 multiplied by 4 is 20. I hope this helps!
Answer:
D
Step-by-step explanation:
you have to distribute the number 5 between all of the numbers. Is because
5 * x is 5x 3y is 15y, and 5 *4 is 20.

find the slope of 4x-y=8 and solve
Answer:
m = 4
Step-by-step explanation:
Slope = 4
Slope-intercept form =
y = mx + b
m = slope
b = y-intercept
y = 4x - 8
Therefore, the slope is 4 and y-intercept is -8.
