Answer:
1. ( 0,-6 ) is y-axis
2. ( 15,4 ) is l quadrant
3. ( 100, -5 ) is lV quadrant
4. ( 0.004, .05 ) is l quadrant
5. ( -4,0 ) is x-axis
8. ( -7.5, -6.3 ) is lll quadrant
9. ( 0.1000) is y-axis.
Answer:
y = -3x + 30
Step-by-step explanation:
First, find the slope using the slope formula:
m = (y2 - y1) / (x2 - x1)
m = (9 - (-3)) / (7 - 11)
m = -12/4
m = -3
Next, find the y-intercept by substituding one of the two points into what the equation is so far:
y = -3x + b
(7, 9)
9 = -3(7) + b
9 = -21 + b
30 = b
Now you have the full equation:
y = -3x + 30
The room is a square, meaning all four sides are 20ft long.
Because we know all the side lengths, we can find the perimeter of the square by adding the side lengths together.
(20 + 20 + 20 + 20) = 80
Now that we know the perimeter, we have to match this number to the feet of crepe paper.
We can find this by dividing the total length needed by the length a single roll provides.
80 / 8 = 10
Therefore, we know that Katie will have to buy a minimum of 10 rolls if she wants to cover the entire perimeter of the room.
Hope this helps! :)
Answer:
D) 2/4
Step-by-step explanation:
2/4 is equivalent to 4/8 which is less than 5/8
Answer:A)33m
B)32.86m/s
Step-by-step explanation:
Using the equation of motion
V^2=U^2-2aS
Where V=final velocity of the car=0
U=initial velocity=17m/s
a=deceleration=-12m/s^2
S= distance covered by car before stopping
Substituting into the equation
0=17^2-2×12×S
0=289-24S
24S=289
S=289/24
S=12m.
The distance between the car and the deer=45-12=33m
B) Using same equation
Distance,S is now 45m,which is the distance between the car and the deer.while deceleration remains same
V^2=U^2-2aS
0=U^2-2×12×45
U^2=1080
U=√1080
U=32.86m/s
