1 ) 3 t ( t + 2 ) - 3 t² =
= 3 t² + 6 t - 3 t² = 6 t = 6 · 19 = 114
2 ) - ( 3 a - 2 b ) - 3 ( - a- b ) =
= - 3 a + 2 b + 3 a + 3 b = 5 b
9/21 because it can still be reduced to 3/7
Answer:
5.7
Step-by-step explanation:
sine cosine tangent
soh cah toa
sine = opposite/hypotenuse
so sin(35)= x/10
you can multiply 10 to both sides to get rid of the 10 denominator on the right leaving you with 10sin(35)=x
be sure your calculator is in degrees.
put that into a calculator leaving you with 5.7
To be apart of that state for atleast ten years is one.
The city do not have up to 5,500 cubic meters of sand that will be needed to combat erosion.
<h3>
Volume</h3>
Volume is the amount of space occupied by a three dimensional object or figure. The volume (V) of a cone is given by:
V = (1/3)πr²h
Where h is the height, and r is the radius
Given that h = 35 m, the radius using Pythagoras theorem:
37² = r² + 35²
r = 12
V = (1/3)π(12)² * 35 = 5280 m³
