Answer:
Let's say that I have $1000.00 to invest for 3 years at rate of 6% compound interest.
M = 1000 (1 + 0.06)^3 = $1191.16.
My $1000.00, after 3 years, is worth $1191.16.
You plug in f(x) into where x is within g(x) so you get G(f(x))=(X+6)^4
90 trucks- for every 2 cars there are 5 trucks
Answer:
54.2 mph
Step-by-step explanation:
Since the drivers leave at the same time and travel in directions 90° from each other, their separation speed can be found using the Pythagorean theorem. Let c represent Cynthia's average speed. Then (c-10) will represent Tim's average speed. Their combined separation speed is 70 miles per hour, so we can write ...
70² = c² +(c -10)²
4900 = 2c² -20c +100 . . . . eliminate parentheses
c² -10c -2400 = 0 . . . . . . . . divide by 2; put in standard form
(c -5)² -2425 = 0 . . . . . . . . . rearrange to vertex form
c = 5 ±5√97 . . . . . . . . . . . . solve for c, simplify radical
c ≈ 54.244 ≈ 54.2 . . . . . . . use the positive solution
Cynthia's average speed was 54.2 miles per hour.
Answer:
6:59
Step-by-step explanation:
Hour : Minute
Small hand is hour hand, large hand is minute hand. Minutes go by the small tic marks, where the hours go off of the numbers.
