Answer:
Step-by-step explanation:
they want to know a point on the line... that has a gradient ( think slope ) of -1/3 and has the point of (-2,5) on it. So find the formula for that line
with the point slope formula y-y1 = m(x - x1)
plug in what we know
y - 5 = - 1/3 (x -(-2))
y - 5 = -1/3(x+2)
y - 5 = -1/3x - 2/3
y = - 1/3x - 2/3 + 5
y = - 1/3x + 4 1/3
y = -1/3x + 13 / 3
Now use your formula to find any new point plug in 1 for x ( b/c it's easy)
y = 12/3 when x= 1. so ( 1, 4 ) is another point on the line :)
don't forget to show your work :P
Answer:
3 3/8 seconds.
Step-by-step explanation:
When it reaches the ground h = 0 so:
54t - 16t^2 = 0
16t^2 - 54t = 0
2t(8t - 27) = 0
t = 0 or t = 27/8 (we ignore the t = 0 ) so:
t = 3 3/8 seconds.
Answer:
The answer is 15 units.
Step-by-step explanation:
If you count the number of units from point A up to the same Y coordinate as point B, the amount of units is 9.
Then, the number of units from that point over to point B is 12 units.
Using this information, you can use the Pythagorean theorem to find that 9 squared is 81, 12 squared is 144, add 144 and 81 to get 225, and then you can find the square root of 225 which equals the answer of 15 units.
A) 13 degrees because it would be 90-77
If two angles are complementary, then the two angles add up to 90 degrees.
If angle A is 77, then the complement would be 90-77 or 13 degrees.
b) The complement of the complement of the angle is the angle itself.
Say the angle A is 30 degrees. It's complement is 90-30 or 60 degrees.
The complement of the 60 degrees is 30 degrees.
So the complement of the complement of the angle would be the angle itself.
Hope this helps :)
Let her total earnings = y (dependent variable)
and her hours worked = x (independent variable)
y = 18x + 75
