Answer: 920
Step-by-step explanation:
828 divided by 0.9 will give you the answer
Well to find this answer, you would have to know the formula of a line, or also known as slope intercept form-- "y= mx+b"
1) Let's find the slope between the two points! (Use the y1-y2 over x1-x2 slope formula)
y1-y2
-------- = slope formula. Use the points 2,8 and 4,12
x1-x2
12-8 4 2
------ = ---- = ----- = our slope is 2!
4-2 2 1
^---- Here we simplify
2) Now we know our slope is 2! Substitute this into the y=mx+b formula
y=2x+b
3) Take one of the points we used for finding the slope and substitute it into our slope-intercept formula. That way we can solve for "b", our y-intercept.
y=2x+b
8= 2(2)+b MULTIPY
8= 4 +b
-4 -4 SUBTRACT (inverse operations)
----------
4=b SIMPLIFY (our final answer)
4) Now we know our y-intercept! Substitute it into the slope-intercept form to get our line.
y=2x+b
y=2x+4
5) Check your work by taking one of the points from above and substitute again!
y=2x+b
12= 2(4)+4
12= 8+4
12=12
Our equation works!
A vertex is a corner and the corner that both the quadrilateral and pentagon share is at point (-3,-5)
Answer:
Step-by-step explanation:
Let be 
, then we must solve for 
by means of the following expression:
(1)
Since it is an inverse trigonometric function, it can be solved only by numerical methods such as application of infinite series such as Taylor series. This approach is used for current scientific calculators. According to scientific calculator we have the following result:
