For this case, the first thing we must take into account is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Substituting values we have:
Trip 1:
50 = v * t1
We cleared t1:
t2 = (50) * (1 / v)
Trip 2:
300 = (3 * v) * t2
We cleared t2:
t2 = (300/3) * (1 / v)
t2 = (100) * (1 / v)
Rewriting:
t2 = 2 (50) * (1 / v)
t2 = 2 * t1
Answer:
His new time compared with the old time was:
Twice the old time.
t2 = 2 * t1.
Answer:
Key difference: Tables represent facts and figures in a row and column format. Charts represent data in a more graphical manner which may include lines, bars and circles.
CHART-graphical display of information wherein the information is illustrated in symbols such as bars, lines, or slices.
TABLE- a means of displaying data or information in rows and columns.
We solve this by the definition of slope in analytical geometry. The definition of slope is the rise over run. In equation, that would be
m = Δy/Δx = (y₂-y₁)/(x₂-x₁)
The x-coordinates here are the t values, while the y-coordinates are the f(t) values. So, let's find the y values of the boundaries.
At t=2: f(t)= 0.25(2)²<span> − 0.5(2) + 3.5 = 3.5
Point 1 is (2, 3.5)
At t=6: </span>f(t)= 0.25(6)² − 0.5(6) + 3.5 = 9.5
Point 2 is (6, 9.5)
The slope would then be
m = (9.5-3.5)/(6-2)
m = 1.5
Hence, the slope is 1.5. Interpreting the data, the rate of change between t=2 and t=6 is 1.5 thousands per year.
Answer:
Step-by-step explanation:
First, lets simplify everything in the parenthesis.
(3×10^2 )×(2×10^−4 )=
In the parenthesis, since exponents come before multiplication in the order of operations, we need to do the exponents first.
(3 • 100) • (2 • 1/10^4)
Now, we can just multiply everything from left to right to get:
6*10^-2
Or
.06
