Step-by-step explanation:
the total surface area is the sum of the individual areas.
we have the ground area : a 6×6 square. = 36 cm²
and we have 4 equal triangles.
the area of a triangle is baseline × height / 2.
which is for each of these triangles
6 × 12 / 2 = 3 × 12 = 36 cm²
so, the total surface area of the pyramid is
36 + 4×36 = 5×36 = 180 cm²
woah this is some crazy is
9514 1404 393
Answer:
H the range is all real numbers
Step-by-step explanation:
The arrows on the ends of the curve mean the curve extends to infinity. Then the domain (x-extent) is -3 to infinity.
The range (y-extent) is -infinity to infinity, <em>all real numbers</em>.
The appropriate description is ...
H The range is all real numbers
The distance between park station 1 and the point where the flare was set off is 73.9 km.
<h3>What is distance?</h3>
Distance is the length between two points expressed in meters or kilometers.
To calculate the distance between park station 1 and the point where the flare was set off can be calculated using Sine Rule
Formula:
- a/sinA = b/sinB....................... Equation 1
Where:
- a = Distance between park station 1 and the point where the flare was set off.
Make a the subject of the equation
- a = bsinA/sinB............ Equation 2
From the diagram,
Given:
- A = 59°
- B = (180-59-75) = 46°
- b = 6.2 km
Substitute these values into equation 2
Hence, the distance between park station 1 and the point where the flare was set off is 73.9 km.
