Step-by-step explanation:
270°/360° ×π×13²
Area of sector=398.20
Answer:
= 0.0009866 N
Step-by-step explanation:
For resolving this problem we can use the impulse-momentum theorem; this theorem establishes that the change in momentum of an object equals the impulse applied to it
The impulse is defined how:
I = Δt
: Average force
Δt = Time interval
Then:
Δt
(0.048)(14) - (0.048)(-23) = (1800)
0.672 + 1.104 = 1800
1.776 = 1800
= 
= 0.0009866 N
Answer:
x - 3/4 is a zero
Step-by-step explanation:
f(x) = x+3/4
To find the zeros, set f(x) =0
0 = x+3/4
Solve for x
Subtract 3/4 from each side
0-3/4 = x+3/4-3/4
-3/4 =x
The zero is -3/4
Answer:
its C
Step-by-step explanation:
2x+4y=450
2x=450-4y
x=450-4y÷2----- equation 1
4x+2y=420
4x=420-2y
x=420-2y÷4----- equation 2
putting the value of x in equation 1
x=450-4y÷2
420-2y÷4=450-4y÷2
2(420-2y)=4(450-4y)
840-4y=1800-16y
840-1800=-16y-4y
-960= -12y
y=80
putting the value of y in equation1
2x+4y=450
2x+4×80=450
2x+320=450
2x=450-320
2x=130
x=130÷2
x=65
<h2> the value of x is 65 and y is 80</h2>
