Answer:
Describe the error in the work shown.
A small submarine starts at –1,260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes. What is the new position of the submarine in relation to sea level?
–1,260 + (–5)(12) = –1,260 + 60
= –1,200
Step-by-step explanation:
N(75/100)=4.5 multiply both sides by 100
75n=450 divide both sides by 75
n=6cm
Answer:
- 3 and 3
Step-by-step explanation:
To evaluate (u ￮ w)(- 1), evaluate w(- 1) then use this value to evaluate u(x)
w(- 1) = (- 1)² + 2 = 1 + 2 = 3, then
u(3) = - 3
---------------------------------------------------
To evaluate (w ￮ u)(- 1), evaluate u(- 1) then use this value to evaluate w(x)
u( - 1) = - (- 1) = 1, then
w(1) = 1² + 2 = 1 + 2 = 3
Answer:
The height of the pyramid is 
Step-by-step explanation:
we know that
The volume of the pyramid is equal to
where B is the area of the base of the pyramid
h is the height of the pyramid
we have
----> the area of the base is the area of a rectangle
substitute the values in the formula and solve for h
