Answer:
99.33ft^2
Step-by-step explanation:
The surface area of a square pyramid is expressed as;
TSA = a²+2a√a²/4 + h²
Given that
a = 5ft
h = 7ft
Substitute
TSA = 5²+2(5)√5²/4 + 7²
TSA = 25+10√25/4 + 49
TSA = 25 + 10√(221/4)
TSA = 25 + 10(√55.25)
TSA = 25 + 10(7.433)
TSA = 25 + 74.33
TSA = 99.33ft^2
Hence the surface area of a square pyramid with side length 5 ft and slant height 7 ft is 99.33ft^2
To figure out how long a king cobra is in feet, you need to find how much 1 meter is in feet.
1 meter is 3.28084 feet. So you need to multiply 3.28084 feet (equals 1 meter) by 4 meters.
A king cobra is 13.1234 feet.
Ok so you have to know the formula density=mass/volume (density is the measure of how much mass is in each unit of volume)
the mass, as measured is 12.9 g
for the volume, to find the volume of the cube multiply the length times the width times the height. Or , since it's a cube, just cube 8
V=8*8*8=512 cm^3
therefore, density= 12.9 g/512 cm^3
since you need to have 1 cm^3 on the bottom, this simplifies to about
.025 g/cm^3
Answer:
D
Step-by-step explanation:
It is y=x^2 because the function you stated is a parabola/quadratic function. You can see that y = 5x^2 +3x + 5 can be made by multiplying D by 5, and adding 3x and 5. If a function has an x^2, y = x^2 is its parent function.
