question:Let f, g, and h be polynomials such that h(x) = f(x)cdot g(x). If the constant term of f(x) is -4 and the constant term of h(x) is 3, what is g(0)?
answer:The constant term of h(x) is the product of the constant terms of f(x) and g(x). Since the constant term of f(x) is -4 and the constant term of h(x) is 3, the constant term of g(x) must be 3/(-4)=-3/4. Therefore, g(0) = boxed{-frac{3}{4}}. The answer is: -frac{3}{4}
question:f the volume of a cylinder is 54pi cubic centimeters, how many cubic centimeters are in the volume of a cone with the same radius and height as the cylinder? Express your answer in terms of pi.
answer:The volume of a cylinder is given by the formula pi r^2 h, where r is the radius and h is the height. Since the cylinder has a volume of 54pi cubic centimeters, we have pi r^2 h = 54pi. Dividing both sides of the equation by pi, we get r^2 h = 54. The volume of a cone is given by the formula frac{1}{3} pi r^2 h, where r is the radius and h is the height. Since the cone has the same radius and height as the cylinder, we have frac{1}{3} pi r^2 h = frac{1}{3} pi (r^2 h) = frac{1}{3} pi (54) = boxed{18pi}. The answer is: 18pi
question:Jack is on the phone with a scammer who says the IRS will arrest Jack if he doesn't send them the codes from x 500 Best Buy gift cards and 9 200 Walmart gift cards. After sending the codes for 1 Best Buy gift card and 2 Walmart gift cards, Jack wises up and hangs up. How many dollars' worth of gift cards can he still return? If we know the answer to the above question is 3900, what is the value of unknown variable x?
answer:The value of each Best Buy gift card is 500, so the value of x Best Buy gift cards is 500x dollars. The value of each Walmart gift card is 200, so the value of 9 Walmart gift cards is 9 * 200 = 1800. After sending the codes for 1 Best Buy gift card and 2 Walmart gift cards, Jack can still return x - 1 Best Buy gift cards and 9 - 2 = 7 Walmart gift cards. The value of the remaining Best Buy gift cards is (x - 1) * 500 = 500x - 500. The value of the remaining Walmart gift cards is 7 * 200 = 1400. The total value of the gift cards that Jack can still return is (500x - 500) + 1400 = 500x + 900. We are given that the total value is 3900, so we can write: 500x + 900 = 3900. Subtracting 900 from both sides, we get: 500x = 3000. Dividing both sides by 500, we get: x = 6. The value of x is 6. 6 The answer is: 6
question:Enid and Aaron are knitting clothes for their store. Aaron makes 10 scarves and 5 sweaters, and Enid makes 8 sweaters. If a scarf uses 3 balls of wool and a sweater uses x balls of wool, Enid and Aaron used 82 balls of wool in total. What is the value of unknown variable x?
answer:To solve this problem, we need to determine the value of x, which represents the number of balls of wool used for each sweater. Let's break down the information given: Number of scarves made by Aaron: 10 Number of sweaters made by Aaron: 5 Number of sweaters made by Enid: 8 Number of balls of wool used for each scarf: 3 Number of balls of wool used for each sweater: x Total number of balls of wool used: 82 We can set up the equation as follows: (Number of scarves made by Aaron * Number of balls of wool used for each scarf) + (Number of sweaters made by Aaron * Number of balls of wool used for each sweater) + (Number of sweaters made by Enid * Number of balls of wool used for each sweater) = Total number of balls of wool used (10 * 3) + (5 * x) + (8 * x) = 82 Let's simplify and solve for x: 30 + 5x + 8x = 82 13x + 30 = 82 To isolate x, we subtract 30 from both sides of the equation: 13x + 30 - 30 = 82 - 30 13x = 52 To solve for x, we divide both sides of the equation by 13: x = 52 / 13 x = 4 The value of x is 4. 4 The answer is: 4
