Answer:
missing side = 50
Step-by-step explanation:
using Pythagoras theorem,
30² + 40² = (missing side)²
900 + 1600 = (missing side)²
(missing side)² = 2500
missing side = √2500
missing side = 50
The answer is C, from where the end lines go down to on the graph
To determine the value of c, use the solution (-1, -1). Substitute the abscissa of the point to x and the ordinate to the variable y.
cx - 3y = 2
c(-1) -3(-1) = 2
The value of c in the equation is 1. Thus, the answer is letter "C. 1".
I visited Indonesia in 1991 but all I can say now is "saya mau beli mango."
It's probably more correct to call the graph (one dimensional) position versus time rather than distance versus time.
(i) The speed will be the slope of the position versus time graph, so in the first ten seconds that's
(ii) The speed is zero when the slope is zero, or flat, horizontal. That's from t=10 seconds to t=20 seconds.
(iii) The last 10 seconds we went from a position of 60 to a position of zero; i.e. we went backwards. That's a speed or slope of
Technically the speed is the absolute value of this velocity, 12 meters per second.
(iv) The average speed is the total change in position over the total time.
Again technically the speed is the absolute value of that, 0.8 meters per second.
Answer:
2y - 9
Step-by-step explanation:
number = y
2 × y - 9
2 × y can be simplified to 2y.
2y - 9
