Answer:
90km² only if it is parallelogram
Step-by-step explanation:
base = 9km
height=10km
area of parallelogram = b x h
=9km x 10km
=90km²
Answer:
A = 4x^2 + 120x
Step-by-step explanation:
(39+2x)(21+2x)-(39*21) = 819 + 78x + 42x + 4x^2 - 819
A = 4x^2 + 120x
Answer:
Step-by-step explanation:
<u><em>To find the centre of the circle, find the mid - point of PQ :</em></u>
<u><em /></u>
<em><u>Diameter = 2 x Radius , To Find the diameter, find distance between P and Q:</u></em>
<em><u /></em><em><u /></em>
PQ is the diameter , therefore radius :
<em><u>Equation of a circle : </u></em>
All of the graphs are color coded and matched
Answer:
Step-by-step explanation:
sec(theta) is defined as:
In the diagram you provided the hypotenuse of the triangle is sqrt(41) and the opposite side is 5, using these two sides, we can solve for the adjacent side by using the Pythagorean Theorem:
So this gives us the equation where a=adjacent side:
Subtract 25 from both sides
Take the square root of both sides
So now plug this into the definition of sec(theta) and you get: . This is in most simplified form since 41, has no factors besides 41 and 1.
