(820*7)-(480*7)=? This is how to solve the equation
#2: This function is not defined if the denominator = 0. So, steal the denom. and set it = to 0, and then solve the resulting eqn: 3x-1=0, 3x = 1, x = 1/3.
The domain is the set of all real numbers except for x = 1/3. The range is the set of all real numbers except for y = 0.
#4: this function will not be defined if 16-x^4 is less than 0.
so you must solve the inequality x^4 ≤ 16. Take the 4th root of both sides. The domain is (-2, 2). By all means, check. Suppose x = 1.5. is x^4≤16?
The smallest value y can have is zero, which occurs when x = plus or minus 2.
X + 1/4x + 1/5x = 58
20/20x + 5/20x + 4/20x = 58
29/20x = 58
x = 58 * 20/29
x = 1160/29 = 40 <== the original number
1350 square feet. 45 *10 = 450 and you convert yards to feet using the ratio of 1:3; 1 yard per 3 feet
Answer: Mount Everest: 8,849.87 meters, Mount Olympus: 2,919.07 meters
Step-by-step explanation: Part A: 5900 Part B: 5930.8 Part C: It's reasonable because part a's answer and part b's answer is pretty accurate and close enough to each other, so yes it is reasonable. But the estimate is very reasonable.
