Answer:
51.26 ft
Step-by-step explanation:
First find the area of the triangle:
a=1/2 base times height
a=(1/2)(6)(4)
a=12 ft
Now find the area of the circles:
a= pi times radius squared
a= pi times 2.5 squared
a=19.63 ft
19.63 + 12 = 31.63 ft
A, dilation because the shape got larger. The other three options just move it around
Answer:

Step-by-step explanation:
<h3>45° - 45° - 90° triangle:</h3>
The ratio of sides of 45 - 45 - 90 triangle is a : a : a√2.
a is the side opposite to 45°.
From the figure, a = 5√11
The side opposite to 90° is a√2.
y = a√2

Answer:
=
+
+ C where C is the constant of integration.
Step-by-step explanation:
i)it is given that the rate of change of W with respect to x is proportional to
x + 18. Therefore
= k(x + 18) where k is a constant.
ii) Therefore
=
+
+ C where C is the constant of integration.
iii) the complete solution can only be found if we know the constant of proportion and also the constant of integration.
