Answer:
7y+21
Step-by-step explanation:
7(y+4)-7
=7y+28-7
=7y+21
Ok so
0.5%=0.005
0.005x=8
x=8/0.005
x=1600
8 is 0.5% of 1600
Hope this helps
If u still don't understand plz message me
If u understand plz brainlest me
If you continue with the same formula with a different problem then you will get it correct
Thank you!
Answer:
Step-by-step explanation:
The figure is made up of a rectangle and two semicircles.
We find the area of the rectangle using the formula;
We find the area of one of the semicircles and multiply by 2;
The area of the semicircles
We substitute 
and 
to obtain;
The area of the figure is
To the nearest tenth we have;
The correct answer is A
A is on the graph. When you plug in 3 in for x you get -4
B is not. When 1 is plugged in you do notnget 4
Answer:
y_c = 2 + 10*x
Step-by-step explanation:
Given:
y'' = 0
Find:
- The solution to ODE such that y(0) = 2, y'(0) = 10
Solution:
- Assuming a solution y = Ce^(mt)
So, y' = C*me^(mt)
y'' = C*m^2e^(mt)
- Back substitute into given ODE, we get:
y'' = C*m^2e^(mt) = 0
e^(mt) can not be equal to zero
- Hence, m^2 = 0
m = 0 , 0 - (repeated roots)
- The complimentary function for repeated roots is:
y_c = (C1 + C2*x)*e^(m*t)
y_c = C1 + C2*x
- Evaluate @ y(0) = 2
2 = C1 + C2*0
C1 = 2
-Evaluate @ y'(0) = 10
y'(t) = C2 = 10
Hence, y_c = 2 + 10*x
