Answer:
4
Step-by-step explanation:
10+-6 is the same as 10-6.
You can see this because there is a addition and subtraction symbol in the middle. You can use the KCC (keep, change, change) method to change the symbols from 10+-6 to 10-6. (You keep the 10, change the subtraction and addition symbols).
Answer: its 4
Step-by-step explanation: Because if you put it on a number line from 0 to 10. go right 10 times. then for -6 you go back left 6 times. and get 4. or just 10 - 6 = 4

What is the slope and y-intercept of the equation 3x -y=3
Answer:
Slope = 3
Y Intercept = 3
Step-by-step explanation:
3x - y = 3
(subtract 3x from both sides - we have to get y by itself)
-y = -3x - 3
(divide by -1 from both side - we need to make y positive)
y = 3x + 3

What is the polygon?A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.
here, we have,
An exterior angle is an angle between a side of a polygon and an extended side adjacent to it.
A polygon refers to any closed curve comprised of a set of connected sides such that no two sides cross.
Convex 55-gon means a convex polygon with n sides.
The sum of measures of any polygon is equal to 360
So, the sum of the measures of the exterior angles of a convex 55-gon is equal to 360.

A. (2, 0) B. (-2, 0) C. (0, 2) D. (0, -2
Answer:
The answer is B. (-2, 0)
Step-by-step explanation:
x= 2 ⋅ cos(π) = −2
y=2 ⋅ sin(π) = 0
The rectangular coordinates is (-2 , 0) , Option B is the correct answer.
What is the equation of conversion of Polar Coordinates to Rectangular Coordinates ?The equation for a polar point ( r, [tex]\rm \theta[/tex]) is
x = rcos [tex]\rm \theta[/tex]
y =r sin [tex]\rm \theta[/tex]
where (x , y) are rectangular coordinates.
The polar coordinate given is ( 2 , π)
r = 2
[tex]\rm \theta[/tex] = π
so
x = 2 cos π
x = 2 * (-1)
x = -2
y = 2 sin π
y = 2 *0
y = 0
Therefore the rectangular coordinates is (-2 , 0) , Option B is the correct answer.

The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially. How many grams of the substance are left after 300 years?
a) 5039.684g
b) 2828.427g
c) 3000g
d) 2000g
Answer:
There are 2,000 grams left after 300 years.
Step-by-step explanation:
Giving the following information:
The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.
First, we need to calculate the reduction of the substance each year:
Yearly reduction= 8,000/400= 20 grams per year
Now, for 300 years:
300 year reduction= 20*300= 6,000
There are 2,000 grams left after 300 years.

Answer:
2.56
Step-by-step explanation:
The equation they dive u: d = 16t^2, so in the question they said what's the distance, d, if t = 0.4
So you just have to replace t with 0.4:
d = 16t^2
d = 16(0.4)^2
d = 16(0.16)
d = 2.56

What’s the distance 3 1/4 and -15
Answer:
18 1/4
Step-by-step explanation:
The easiest way to do this is to start at 0 and go 3 1/4 units to your right.
Then start at 0 and go -15 units to your left. So far I have not used a formula because I want you to see intuitively what the answer is. Then we'll do it with a formula.
The total distance is 3 1/4 + 15 = 18 1/4. Purists will hate the way I've done it, but beginners should understand what they are doing.
A formula would look like this
distanace = sqrt( x2 - x1 )^2 + (y2 - y1)^2 )
distance = sqrt( (3 1/4 - - 15)^2 + (4 - 4)^2 )
distance = sqrt( (18 1/4 )^2 + 0)
distance = 18 1/4
