Answer:
Step-by-step explanation:
10. From the given figure,


11. From the given figure,


and 

12. The sides of an equilateral triangle has length=10 inches, therefore AB=BC=AC=10
Also, AD is the height of the given triangle,then BD=DC=5
From triangle ADC,




Hence, height of the triangle is 
13. Height of the ramp from the ground is 8ft.
therefore, let BC=x



14. Let BC=x and AB=y
then, 

and 

The perimeter of triangle is=Sum of all the sides=AB+BC+AC=
15. Let AB be the height of the tree, then


16. According to question,


Answer:
depends how many questions are not multiple choice questions if i get that info then i can tell you how many are multiple questoions

Answer:
Step-by-step explanation:
Where is f(x)? My answers pertains only to g(x) = -x^2 + 2x + 4.
Part of B is true: As x approaches infinity in either direction, g(x) approaches negative infinity. The graph of g(x) is an inverted parabola.

Step-by-step explanation:
(a)
The shaded figure is a trapezium with area (A)
A = 0.5 h(a + b)
where h is the perpendicular height and a, b the parallel sides, thus
A = 0.5 × 10 × (8 + 14) = 5 × 22 = 110 cm²
(b)
The volume (V) of the prism is calculated as
V = area of end face × depth
= 110 × 3 = 330 cm³
