Answer:
Since the formula is (1/2) base height, (1/2) of 10 is 5 so multiply 5 times the base polynomial resulting in 20x^2y + 10xy^2 ft^2. So, if you multiply the length times width then divide by 2 you get the same answer. Sorry if this is incorrect.
Hope this helps, have a great day and stay safe!
X= -7 y=2 (-7,2).
You multiply the first equation by 2 and the second by 3, then you can cancel out the x values to get the y value. Then you go back and plug in the y value to get x.
Answer:
theta = all real values
Step-by-step explanation:
sec theta + tan theta = cos theta / (1-sin theta )
sec theta = 1/cos theta
tan theta = sin theta/cos theta
1/cos theta + sin theta /cos theta= cos theta/ (1-sin theta)
(1+ sin theta) / cos theta = cos theta /( 1-sin theta)
using cross products
(1+sin theta) * (1-sin theta) = cos theta * cos theta
1 +sin theta - sin theta- sin^2 theta= cos ^2 theta
1 - sin ^2 theta= cos ^2 theta
cos ^2 theta= cos ^2 theta
this is an identity so it is true for all theta
Let's use the slope intercept form of a line which is:
y=mx+b where m=slope and b=y-intercept.
Mathematically m=(y2-y1)/(x2-x1) and the y-intercept is just the value of y when x is equal to zero, where the line intercepts the y axis...
First you want to find the slope by finding two clearly identifiable points on the graph...I'll pick (4,4) and (0,1), now we can calculate the slope or "m"...
m=(4-1)/(4-0)=3/4 so now we can say our line is:
y=0.75x+b, using point (4,4) we can now solve for b.
4=0.75(4)+b
4=3+b
b=1 so the line is"
y=0.75x+1
We'll use the notation 
for the principal value and 
for all the values:
Part I
Part II. In our range we can write
Part III.
Part IV.
