Answer:
8.9m/s
Step-by-step explanation:
Time= 28s
Displacement= 250m
Velocity=?
Velocity (v) = displacement (d)/ Time (t)
V= 250/28
V=8.9m/s
OR YOU CAN APPROXIMATE IT
V=8.928
YOU CAN APPROXIMATE IT TO
V=8.93m/s
Sum/difference:
Let
This means that
Now, assume that 
is rational. The sum/difference of two rational numbers is still rational (so 5-x is rational), and the division by 3 doesn't change this. So, you have that the square root of 8 equals a rational number, which is false. The mistake must have been supposing that was rational, which proves that the sum/difference of the two given terms was irrational
Multiplication/division:
The logic is actually the same: if we multiply the two terms we get
if again we assume x to be rational, we have
But if x is rational, so is -x/15, and again we come to a contradiction: we have the square root of 8 on one side, which is irrational, and -x/15 on the other, which is rational. So, again, x must have been irrational. You can prove the same claim for the division in a totally similar fashion.
Answer:
<em>x = 9</em>
Step-by-step explanation:
The standard form of equation of a line is expressed as y = mx+c
m is the slope
c is the y intercept
Note that the line does not have a slope and the x intercept of the line is a point where the line cuts the x axis. Hence the equation of the line will be expressed as x = c where c is the x intercept;
<em>From the graph, the x intercept =9. Hence the equation of the given line is x = 9</em>
Answer:
x = 5
y = 9
Step-by-step explanation:
Since the scale is 2, the side of x needs to 4 because the corresponding side on the other figure is 2 (2 * 2 = 4).
So, x - 1 = 4
x = 5
Similar to the y side, the y side needs to be 10.
So, y + 1 = 10
y = 9
Answer:
10=19-11
Step-by-step explanation:
that answer is false because 19-11 = 8 not 10
