Answer:
a)
v=<400, 450+3t, 600-9.81t> m/s
r=<400t, 450t+3
/2, 15+600t-9.81/2> m/s
b) attach file
c) t=122.324s
d) z=18369.9854 m
Step-by-step explanation:
a)
The equation for velocity of each component is v=
+at, in this case the x-axis component has acceleration 0
, the y-axis component has acceleration 3 and the z-axis component has -g, where g=9.81.
The equation for position of each component is x=
+t+a/2,
with <, 
,
>=<0,0,15>.
c) This time is t when z=0, with positive sign.
d)Solving the equation 
=
+ 2*a*(z-) for z, with 
=0.
Length of the rectangle is 8 units
Step-by-step explanation:
- Step 1: Find the length, let width be x.
Area of the rectangle = 48 units
Length = x + 2
⇒ Area = Length × Breadth
48 = x (x + 2)
48 = x² + 2x
x² + 2x - 48 = 0
x² + 8x - 6x + 48 = 0 (Product Sum rule to factorise)
x(x + 8) - 6(x + 8) = 0
(x - 6)(x + 8) = 0
⇒ x = 6, -8 (negative value is neglected)
∴ x = 6
x + 2 = 8
Answer:
11
Step-by-step explanation:
Replace the variable xx with −1-1 in the expression.
f(−1)=−3⋅−1+8f(-1)=-3⋅-1+8
Simplify the result.
Tap for fewer steps...
Multiply −3-3 by −1-1.
f(−1)=3+8f(-1)=3+8
Add 33 and 88.
f(−1)=11f(-1)=11
The final answer is 1111.
=11

Answer:
10 feet length and 6 feet width.
Step-by-step explanation:
If the total area of the patio is going to be equal to 60 square feet and the length is going to be 4 feet longer than the width, the dimensions that she should use for the patio are 10 feet for the length and 6 feet for the width which will equal to 60 square feet in total.
I hope this answer helps.
Step-by-step explanation:
I'm not sure if this will help but to find out how much coffee 4 people would need you would have to divide 4 into 5 which is 1 1/5
EQUATION-- 4/5= X
I chose that because / means divide 5 into 4 would give you x we don't know what x is until we actually do the problem
Even if im not correct I hope it helped a bit
