Answer:
Original value of investment = £500 (Approx.)
Step-by-step explanation:
Given:
Rate per year = 4%
Number of year = 3 years
Value of investment after 3 year = £562.43
Find:
Original value of investment
Computation:
A = P[1+r]ⁿ
562.43 = P[1+4%]³
562.43 = P[1+0.04]³
562.43 = P[1.04]³
562.43 = P[1.1248]
Original value of investment = 562.43 / 1.1248
Original value of investment = 500.026
Original value of investment = £500 (Approx.)
Answer:
30 pages
Step-by-step explanation:
Because if he reads 10 pages in 1/3 of a hour 1/3 of an hour is 20 mins so x2 means 30 pages
Answer:
Step-by-step explanation:
x-intercepts are SOLUTIONS to a quadratic whereas when you put those solutions into factor form (in a set of parenthesis), you have the FACTORS of the quadratic. They are the same thing generally, they are just written in different forms. For example, if a solution to a quadratic is x = 3, it has been understood that x = 3 when y = 0. Therefore, if x - 3 = y and y = 0, then x - 3 = 0. Solving that for x, you get x = 3. That factor of x = 3 is (x - 3).
Following that logic, for a:
If the x intercepts are x = 0 and x = 3, it is understood that x + 0 = 0 so x = 0 and the factor is (x + 0) (it could also be x - 0 since adding 0 is the same as subtracting 0); if x = 3 it is understood that x - 3 = 0 and the factor is (x - 3).
For b:
If the x-intercepts are x = -1 and x = 1, then originally the factors were (x + 1) and (x - 1). Again, set each of those equal to 0 and solve for x (THE X-INTERCEPT EXISTS WHERE Y = 0!)
For c:
If the x-intercepts are x = -5 and x = 10, then originally the factors were (x + 5) and (x - 10).
For d:
If the x-intercept is a fraction, do the same thing:
x = 1/2 so
x - 1/2 = 0 Now multiply both the x and the 1/2 by a 2 to get the factor (2x - 1) and the other factor from x = 4 is (x - 4)
I think the answer is C, y= log 25^x. Logarithmic functions are inverses of exponential functions. the inverse of exponential function y =a ^x is x = a^y. The logarithmic function y = logaX, is defined to be equivalent to the exponential equation x= a^y.
