Answer:
Step-by-step explanation:
Let's find a solution by understanding the following:
The acceleration rate is defined as the change of velocity within a time interval, which can be written as:
where:
A=acceleration rate
Vf=final velocity
Vi=initial velocity
T=time required for passing from Vi to Vf.
Using the problem's data we have:
Vf=65miles/hour
Vi=6miles/hour
T=14.8seconds
Using the acceleration rate equation we have:
, but look that velocities use 'hours' unit while 'T' uses 'seconds'.
So we need to transform 14.8seconds into Xhours, as follows:
Using X=0.0041hours in the previous equation instead of 14.8seconds we have:
In conclusion, the acceleration rate is
If u have a open circle, then the inequality has no equal sign. But if it is a closed circle, the inequality has an equal sign.
Shading to the left means " less then " .
Shading to the right means " greater then " .
(1) u have an open circle on -7 with shading to the left....
x < -7
(2) u have a closed circle on 4.5 with shading to the left....
x < = 4.5 (thats less then or equal)
(3) u have an open circle on -5 with shading to the right...
x > -5
(4) u have an open circle on 1.5 with shading to the right...
x > 1.5
Answer:
The second answer: y= 3/4x + 2
Step-by-step explanation:
Subtract 4x to the other side
Divide by 3 to get y by itself
Make the coefficient of the x term the negative reciprocal, for that is the perpendicular slope of the line
X5 • (3x3 - 2) • (4x + 5)
Answer:
Simple sum. The symbol Σ (sigma) is generally used to denote a sum of multiple terms. This symbol is generally accompanied by an index that varies to encompass all terms that must be considered in the sum.
