Two mechanics worked on a car. The first mechanic worked for
yuradex [85]
Create equations:
10X+15y=2575.
X+Y=210.
Solve for X: X=210-Y, and sub it into the other equation: 10(210-Y)+15Y=2575. Solve for Y: 2,100-10y+15y=2575, 5y=475, y=95.
Sub Y into the original problem: X+95=210. Solve: X=115.
The first mechanic charges $115 per hour and the second charges $95 :)

Pam and her brother both open savings accounts. each begin with a balance of $0. For every $2 is that Pam saves in her account her brother saves $5 in his account

P:bro=2:5
when P=40 what is bro?

2/5=40/b
times 5b both sides
2b=200
divide 2
b=100
bro has $100

A particle moves along the x-axis so that at time t its position is given by s(t) = (t + 1)(t - 3)3, t > 0. /p>For what va
Zepler [3.9K]

Given the position function, the velocity function is obtained by taking the derivative:

s(t)=(t+1)(t-3)^3\implies v(t)=(t-3)^3+3(t+1)(t-3)^2

The velocity is increasing its own derivative is positive, so we also have to find the acceleration by taking another derivative:

a(t)=4(t-3)^3+3(t-3)^2+6(t+1)(t-3)

To find when a(t)>0, we first need to know where a(t)=0:

4(t-3)^3+3(t-3)^2+6(t+1)(t-3)=(t-3)\bigg(4(t-3)^2+3(t-3)+6(t+1)\bigg)=(t-3)(4t^2-15t+33)=0

The quadratic factor is always positive (its discriminant is negative), which leaves one solution at t=3. To either side of t=3, we have, for instance,

a(2)=-12

a(4)=36>0

which indicates that v(t) is increasing for t>3, making the answer A.
