HOW DO YOU SEE IT? Direct link to ikigai54321's post Sal Khan I believe.. (42x + 1) = 64 A population of 30 mice is expected to double each year. The question, What do we know and how do we know it? occupies the mind of the epistemologist. x = -3 Answer: Question 63. How did you apply what you know to simplify the complicated situation in Exercise 56 on page 297? y = a(1 + r)t f(t) = \(\frac{1}{3}\)(1.26)t, Answer: In Exercises 21 and 22, rewrite the expression in radical form. r = \(\frac{5}{5}\) \(\frac{4}{5}\) c. Use the term in part (b) to add another square to the diagram and extend the spiral. Given when bases are equal powers should be equated an = 486(3)9-1 x = 0 f(-3) = 5, f(-1) = 5 The second term of a sequence is 7. b > 1 The function f(t) = 5(4)t represents the number of frogs in a pond after t years. So, the next three terms are 9, \(\frac{27}{2}\), \(\frac{81}{4}\). The value of the car decreases by 14% annually. y = a(1 r)t y = 14.76(1.4)t ERROR ANALYSIS y = (\(\frac{7}{8}\))t When bases are equal powers should be added. Chemistry is one of the more important and challenging subjects of CBSE Class 12 Science stream. Write your answer in scientific notation and in standard form. 205/128 1.6 The number with the greater power of 10 will be the greater number. 128% can be written as 128/100 a4 = 16/4 = 4 (-3, 0) x = 4, Answer: How many people will have visited the website after it is online 47 days? Question 59. There are a total of 128 teams at the start of a citywide 3-on-3 basketball tournament. b < 1 Answer: f(t) = 0.4/1.16 (1.16)t b. y 6 = 3x 6 = 104/106 . Explain your reasoning. Times Greater Than Calculator This calculator calculates A times greater than B. You purchase a car in 2010 for $25,000. Answer: Question 27. y5/y4 = 1.34 FV = 750(1.0125)4t, Question 19. 1 r= 0.5 a1 = \(\frac{3}{49}\) Answer: Question 26. y = 50(2)3 So 9 is the same Question 39. EXPLORATION 1 Answer: Question 4. Determine whether the function represents exponential growth or exponential decay. The first point is (1, 64) When I learned this many years ago, I remembered I was taught that 3 times bigger than is the same meaning with 3 times as big as. Question 1. How can you write general rules involving properties of exponents? c. Which is greater, 10,000 milligrams or 1000 decigrams? In 2012, on average, about 9.46 10-1 pound of potatoes was produced for every 2.3 10-5 acre harvested. . 8x 2 = \(\sqrt{8}\) d. 8,000 is 10 times as much as 800. n = 7 How many times greater is the value of the 4 in 5462 than the value of the 4 in 2341? Yes, the thickness of the paper is taller than us since when we fold the paper of thickness 0.1 mm in half 15 times, we get 326.78 cm of the thickness of the paper. g(-3) = 8(-3) + 16 = -8 common ration = -3 log 200000 = log (192) + log (4x 3) 81, -27, 9, -3, . So for the first number, 5, 462. 6, 1, 7, 8, 15, 23, . = y = 1.5(2)-2 = 1.5\(\sqrt[2]{2}\) a. y = P(1 + r/n)nt 3x 2 = 1 And here-- let me do that t: the amount of time in years Compare the graph of y = 2(5)x with the graph of y = 5x. Each term of the sequence is 13 less than the preceding term. What is 10 times greater than 6? a. So, the recursive rule for the sequence is a1 = -14, an = an-1 + 6, Question 34. -1x = -5 y 5 = 0 Answer: a10 = 4^9 = 262144 Answer: t(44) = 1.1 t(43) Identify the initial amount, decay factor, and decay rate. MODELING WITH MATHEMATICS Question 17. Answer: Question 56. iv. Answer: Question 60. Question 39. I really like this new calculator and I did just join BYJUS learning program and I have been apart of the program for about half a year now. a1 = 5 Check your answer. y = \(\frac{1}{4}\) (2) 3y = 6x 12 Answer: Question 28. If x increases then y increases, implying that the given exponential function is an exponential growth function. 7/100 multiplied So, 1000 is thousand times bigger than 1. then How many times is 7000 greater than 70? 2x 1 = x/4 answer choices 10 times 100 times 9 times 1,000 times Tags: Question 2 SURVEY 30 seconds Q. You zoom in repeatedly to 25% of the screen size. Each term of the sequence is 5 times the preceding term. (See Example 1.). -t 7t = 21 5 t(43) = 1.1 t(42) 5) = (10) = 100 Answer: Question 38. In the example given, one number is larger because it has a higher value in the tenths place, even though the other number has a higher value in the hundredths and thousandths places.
