No the answer is not always postive. For example. If you had -50 and subtracted -30 you would have -20.
Answer:
Total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
Step-by-step explanation:
We have given number of students = 10
These 10 students are assigned to four dorm rooms a single, a double, a triple and a quad
So number of ways to assigned single student
Now left student = 10 -1 = 9
So number of ways to assigned double student
Now left student = 9-2 = 7
So number of ways to assigned triple student =70
Now left student = 7 - 3 = 4
So number of ways to assigned quad student
So total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
Answer:
The x-intercept is the point (22,0)
Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to
take the points
(-38,40) and (-23,30)
substitute the given values
step 2
Find the equation of the line in point slope form
we have
substitute
step 3
Find the x-intercept
Remember that the x-intercept is the value of x when the value of y is equal to zero
so
For y=0
solve for x
Multiply by 3 both sides
therefore
The x-intercept is the point (22,0)
<u>Answer</u>
Part 1: l = -1.665g
Part 2: Max-mum the spring can support.
Part 3: The spring constant.
<u>Explanation</u>
Gradient is also called the slope.
Slope = (change in y) /(change in x)
= (60 -40)/(6.7 - 40)
= 20 / -33.3
= - 0.600600601
Since the graph is a straight line, the equation would be,
m ∝ l
m = kl Where K is the constant.
<u>g</u> = -0.60l
l = -1.665g
<u>Part 2</u>
The Y-intercept represent the mix-mum weight the spring can support.
<u>part 3</u>
The slope in this case represent the spring constant.
Answer:
2.052 + 5.638i
Step-by-step explanation:
expressing in trigonometric form
= | |(cosΘ + isinΘ )
= 6(cos70° + isin70°)
= 2.052 + 5.638i
