Answer: 40, 30
Step-by-step explanation:
Answer:
d = 
Step-by-step explanation:
1) To solve for d, isolate it in the equation. So, to get rid of the 
with the d, add 
to both sides.
Thus, d = .
Answer:
£ 2.8
Step-by-step explanation:
4 kg = 1.60
1 kg= 1.6/4 = £0.4
7 kg = 0.4*7 = £2.8
This is an exponential function.
If x = 0, 2^x = 2^0 = 1. The beginning value of 2^x is 1 and the beginning value of 51*2^x is 51.
Make a table and graph the points:
x y=51*2^x point (x,y)
-- --------------- ---------------
0 51 (0,51)
2 51*2^2 = 51(4) = 204 (2,204) and so on.
The graph shows up in both Quadrants I and II. Its y-intercept is (0,51). Its slope is always positive.
Answer:
8 hours
Step-by-step explanation:
We can use a ratio to solve
12 hours x hours
---------- = ------------
93 dollars 62 dollars
Using cross products
12 * 62 = 93x
Divide each side by 93
12*62/93 = 93x/93
8 = x
8 hours
