Given:
In a right angle triangle ABC, , and
To find:
The value of AC.
Solution:
In a right angle triangle,
On cross multiplication, we get
Therefore, the measure of AC is 12.304 m.
Answer:
x=√-y^2-10y
Step-by-step explanation:
step 1:add y^-2 to both sides
x^2+(y+5)^2=25
x^2+y^2+10y+25+-y^2=25+-y^2
x^2+10y+25=-y^2+25
Step 2:add -10y to both sides
x^2+10y+25-10y=-y^2+25+-10y
x^2+25=-y^2-10y+25
step 3:add -25 to both sides
x^2+25-25=y^2-10y+25-25
x^2=-y^2-10y
step 4:take square root
x=√−y^2−10y
Formula for Riemann Sum is:
interval is [1,3] so a = 1, b = 3
f(x) = 3x , sub into Riemann sum
Continue by simplifying using properties of summations.
Now you have an expression for the summation in terms of 'n'.
Next, take the limit as n-> infinity.
The limit of
goes to 0, therefore the limit of the summation is 12.
The area under the curve from [1,3] is equal to limit of summation which is 12.
You need to add what the lines are if you want them to be analysed for you^^
