Answer:
The answer would be A, D, and C.
Step-by-step explanation:
y=1, so
1 > 2(1) -2
1> 2-2
1>0 TRUE
NEXT.
y=3
3> 2(-1) -2
3>-2-2
3> -4 TRUE
NEXT
y=-2
4>2(2) -2
4 > 4-2
4>2 TRUE!
I hope this helps!
Answer:
The 6 in 4,786.53, is 6 times greater than the 6 in 3,821.69.
Step-by-step explanation:
The value of 6 in 4,786.53, is in the ones. 6
The value of 6 in 3,821.69, is in the tenths. 0.6
6/0.6 = 10
The 6 in 4,786.53, is 6 times greater than the 6 in 3,821.69.
Hope that helps!
Remark
This may be a little confusing, but because they are travelling in opposite directions, the distances add when you want to get how far apart they are.
d1 + d2 = 1541
Equation
Let the time this happens = t
d1 = 323*t
d2 = 347*t
323*t + 347*t = 1541 Combine like terms on the left.
670t = 1541 Divide by 670
t = 1541/670
t = 2.3 hours pass before the distance of 1541 miles are between the two planes. You might need the answer to be 2 hours 18 minutes.
Answer:
undefined
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -4-4)/( -3 - -3)
= ( -4-4)/( -3+3)
= -8/0
When we divide by zero, the answer is undefined so the slope is undefined
Answer:
there is no collision between the particles
Step-by-step explanation:
for the first particle
x1=3sin t, y1 = 2 cos t, 0 ≤ t ≤ 2π
for the second particle
x2 = -3 + cos t, y2 = 1 + sin t, 0 ≤ t ≤ 2π
then for the collision
x1=x2 → 3*sin t = -3 + cos t → sin t= -1 + (cos t)/3→ 1+ sin t = (1/3)cos t
y1=y2 → 1 + sin t = 2 cos t → (1/3)cos t = 2 cos t →(1/3) = 2
since 1/3 ≠ 2 there is no collision between the particles
