The expression that can be used to find profit is 20x – 50 and that profit when 75 pairs of jeans are sold is 1,450.
<h3>How find profit function and the profit?</h3>
Let R represents the revenue function and C represents the cost function, the two functions can be stated correctly as follows:
R = 2x^2+17x−175
C = 2x^2−3x−125
Let P represents the expression that can be used to find profit, we therefore have:
P = R – C
P = 2x^2+17x−175 – (2x^2−3x−125)
P = 2x^2+17x−175 – 2x^2 + 3x + 125
P = 2x^2 – 2x^2 + 17x + 3x – 175 + 125
P = 20x – 50
The profit when 75 pairs of jeans are sold can therefore be calculated as follows:
P = (20 * 75) – 50
P = 1,450

<h2>
Answer:</h2>
<em><u>Driver experiences 17.68 G's on an average.</u></em>
<h2>
Step-by-step explanation:</h2>
In the question,
We know that in a car crash the speed of the car goes from the <u>speed of 26 m/s to 0 m/s</u> in <u>0.15 seconds</u>.
So,
The final speed, v = 0 m/s
Initial speed, u = 26 m/s
Also,
Time in seconds, t = 0.15 s
So,
Using the equation of law of the motion, we get,
v = u + at
0 = 26 + a(0.15)
a = -26/0.15
<u>a = -173.33 m/s²</u>
As, there is deceleration of the car is taking place the acceleration is in negative.
Now,
To convert it into the force in the <u>G's</u> we need to divide the <u>deceleration</u> by the <u>acceleration (gravity), g.</u>
So,
<u>G's experienced by the driver on an average</u> is given by,
<em><u>Therefore, on an average the driver experiences 17.68 G's.</u></em>

Answer: 4600
Step-by-step explanation:
Jack divided his fortune of 92,000 into 8 equal parts. This means a part will be equal to:
(92000 ÷ 8) = 11500.
He gave 4 parts to his wife. This means his wife has:
(11500 × 4) = 46000.
1 part to his son means that his son has: (1 × 11500) = 115000.
He gave the last 3 parts and evenly it among 5 charities. This means:
(3 × 11500) = 34500 was shared among 5 charities. Each charity will get: (34500 ÷ 5) = 6900
To calculate how much more money did his son get than the charities will be:
11500 - 6900 = 4600
