The value of p is (x22)(3x•21)
Answer: b = 15, the perimeter is 40, and the area is 60.
Step-by-step explanation: First we need to find b. Using the Pythagorean Theorem, we know what 8^2 + b^2 = 17^2. This is the same as 64 + b^2 = 289. Subtract 64 from each side and we get b^2 = 225, which happens to be 15^2, so b=15. Now that we have b, we can add 8 + 15 + 17 to get the perimeter, 40. The area comes from 1/2*base*height, so 1/2 * 8 * 15. The area of the triangle is 60.
Given that question: Shyam invested money in the stock market. In the first
year, his stock increased 20%. He paid his stock broker $300 and then lost
$450. He withdrew $500, and then his remaining investment doubled. Shyam’s investment is now worth $7100. How much was Shyam’s original investment?
The solution is as follows:
Let the amount Shyam invested in the stock market be x, then in the first year his stock increased by 20% giving 1.2x.
He paid his stockbrocker $300 to have 1.2x - $300 left, and he lost $450 to have 1.2x - $300 - $450 = 1.2x - $750 left.
He withdrew $500 to have 1.2x - $750 - $500 = 1.2x - $1,250 left.
His remaining investment doubled to have 2(1.2x - $1,250) = 2.4x - $2,500
Shyam's investment is now worth $7,100 which means that
2.4x - $2,500 = $7,100
2.4x = $7,100 + $2,500 = $9,600
x = $9,600 / 2.4 = $4,000
Therefore, the value of Shyam's original investment is $4,000
