First, simplify the inequality
3x-5 _< -2
3x _< 3
x_< 1
x is less than or equal to 1
so any number less than 1 or 1 itself could be solutions
EX: 1, -5, -36
Answer:
Part 1) The engine speed that maximizes torque is
Part 2)The maximum torque is
Step-by-step explanation:
<u><em>The correct equation is</em></u>
This is the equation of a vertical parabola open downward (because the leading coefficient is negative)
The vertex represent a maximum
The x-coordinate of the vertex represent the engine speed that maximizes torque
The y-coordinate of the vertex represent the maximum torque
Solve the quadratic equation by graphing
using a graphing tool
The vertex is the point (3.093,74.683)
see the attached figure
therefore
The engine speed that maximizes torque is
---> because is in thousands of revolutions per minute
The maximum torque is
Answer:
2.25t
Step-by-step explanation:
Given function:
- 7.5% and 30t
- to find 7.5% of 30t
- t is just a variable
Multiply 7.5% with 0.01:
- ·
Multiply 0.075 by starting term:
- ·
Therefore, 7.5% of 30t would be 2.25t.

Answer:
Julie and her 2 sisters want to buy a new videogame, it costs $20, if their grandmother gives them $3.20 to buy it, how much will each have to pay?
Step-by-step explanation:
When you have a problem like this you just have to thing on a reason to multiply by a fraction and a withdrawal from the total, if you are multiplying by a fraction, that means you are dividing money, so thats why we put julie and her sisters as subjects, and her grandma givin them money is to withdraw from the total amount those $3.20
