Answer:
C
Step-by-step explanation:
A = 1 = Point
B = 2 = Line
C = 3 = Plane
I hope this helps and that you have a great day :)
A vertical translation only is shown, B, because the triangle moves up; vertical means to move something up or down.
Answer:
x=-3
y=3
Step-by-step explanation:
-27=-9x-18y equation 1
-5y-10x-15=0 equation 2
using equation 2 we have:
-10x -15 =5y
y= -2x -3 equation 3
using equation 3 in equation 1 we have:
-27=-9x-18(-2x -3)
-27= -9x +36x +54
-27-54 =27x
-81 = 27x
so we have:
x= -81/27
x=-3
y= -2(-3) -3
y= 6-3
y = 3
Answer:
It takes 534.54 watts
Step-by-step explanation:
Given :
Mass of the book = 30kg
Distance = 10m
Time = 5.5 sec
To Find:
How much power did it take = ?
Solution:
Step 1: calculate the work done
Work done = 
where
m = mass
a = acceleration due to gravity
d = distance
Substituting the values,
Work done = 
=> 2940 Nm
Step 2: calculate the Power
We know that
Substituting the values,
Power = 534.54 watts
Answer:
f(t) = 66·0.995^t
Step-by-step explanation:
You can try t=0 and t=1 in each of the formulas to see which one gives values of 66 and 0.5% less than 66, or 65.67.
The first function has an initial value of 0.5, so is not correct.
The second function gives f(1) = 99, so is not correct.
The third function gives f(1) = 65.67, so is correct.
The fourth function gives f(1) = 66.33, so is not correct.
_____
You can realize that the multiplier will be 0.5% less than 100%, so will be 99.5% = 0.995. This number shows up only in the third selection.
