Answer:
D
Step-by-step explanation:
I think it is D because exponential graphs usually have a curve to them. And the one you need is exponential decay so D is negative and exponential.
HOPE THIS HELPS! HAVE A GREAT DAY!! :)
Answer:
V ≈ 226.72 cm³
Step-by-step explanation:
Use the formula for volume of a cone using slant height and radius.
V = 1/3 π r² √ l² - r²
Then, plug in dimensions and solve.
V = 1/3 π (10)² √ 10² - 5²
V ≈ 226.72 cm³
Hope I could help!!! Good luck!!!
Answer:
D and C
Step-by-step explanation:
because EF is diameter
then radius diameter divided by 2
First, lets transform the given vector into an unit vector (dividing by its module)
UnitVec = 4/5 i + 3/5 j
Then lets change this vector into a polar form
UnitVec = 1. with angle of 36.869 degrees taking as a reference the i vector
Then, the probem tells us that the vectors u and v make an angle of 45 degrees with UnitVec, so lets add+-45 to the vector in polar form
U = 1*[cos(36.869 +45)i + sin(36.869 +45)j] = 0.1414 i + 0.9899 j
V = 1*[cos(36.869 -45)i + sin(36.869 -45)j] = 0.9899 i - 0.1414 j
