Answer:
2/5
Step-by-step explanation:
4+19=25
square root of 25 is 5 so
adjacent over hypotenuse is 2/5
this might be wrong but I think this is how u do it
Answer is C. By solving x-y=-5 to x=-5+y and converting 2x + y = -1 into 2x + x + 5 = -1 the answer becomes -2 =x. By plugging that into 2 (-2) + y = -1, the answer is y=3. So your answer is C
Answer:
7.7 seconds
Step-by-step explanation:
To find how long would take to the object fall to the ground from the top of the building, we just need to use the function given (which express the position of the object in a certain time):
s(t) = 16*t2
The height of the tower is 949 feet, so the total height the object will fall is 949 feet. Using this value for s(t), we can find the value of t (the total amount of time that will take to travel this distance):
949 = 16*t2
t2 = 949 / 16
t2 = 59.3125
t = 7.7015 seconds
So it would take 7.7 seconds for the object to fall to the ground from the top of the building.
Answer:
6
Step-by-step explanation:
A line that passes through the point (x,y), with a y-intercept of b and a slope of m, can be represented by the equation .
If a line has the slope of -0.5, then m=-0.5 and the equation of the line is
This line passes throughthe point (10,1), then the coordinates of this point satisfy the equation of the line:
and the equation of the line is
Since b=6, the y-intercept of the line is 6.
