Answer:
A.(5,1) to
Step-by-step explanation:
because the y axis is on a 5 and the x axis doesn't have a question ❓⁉️ so you have (A) to be your answer
Given:
4 1/7 * 3 3/5
4 1/7 = (4*7)+1/7 = 29/7
3 3/5 = (3*5)+3/5 = 18/5
29/7 * 18/5 = 29 * 18 / 7 * 5 = 522 / 35 = 14.91
Simplified expression.
4 x 3 1/2
3 1/2 = (3*2)+1/2 = 7/2
4 * 7/2 = 4*7 / 2 = 28 / 2 = 14
It is a close estimate. Actual: 14.91 vs Estimate: 14
A is the correct answer I do believe
The coordinates of point P are: (1/5 , -12/5)
Step-by-step explanation:
Here
R(-3,-4) = (x1,y1)
S(5,0) = (x2,y2)
The ratio is: 2:3
The coordinates of a point that divides the line in ratio m:n are given by:
Let P be the point then
Putting values
Hence,
The coordinates of point P are: (1/5 , -12/5)

Answer:
c=80
Step-by-step explanation:
Based on my reading the critical damping occurs when the discriminant of the quadratic characteristic equation is 0.
So let's see that characteristic equation:
20r^2+cr+80=0
The discriminant can be found by calculating b^2-4aC of ar^2+br+C=0.
a=20
b=c
C=80
c^2-4(20)(80)
We want this to be 0.
c^2-4(20)(80)=0
Simplify:
c^2-6400=0
Add 6400 on both sides:
c^2=6400
Take square root of both sides:
c=80 or c=-80
Based on further reading damping equations in form
ay′′+by′+Cy=0
should have positive coefficients with b also having the possibility of being zero.
