Answer:
Hello first one is 4.
Second one is 8
Step-by-step explanation:
First one is f(0). It means you should put zero in the place of x
0 is less than 5 so you should put zero in x+4=f(x)
For the second one do like the first one.
I hope you understand
Answer:
1^x-2
Step-by-step explanation:
First you put log(10)^x into the calculator, the product is 1^x. Then you subtract that by log(10)^3 which you you get 1^x-1 then you subtract that answer by 1 to get 1^x-2.
This would be a reflection.
Let 'x' be the distance from THE far bank where 700 is the distance to the NEAR bank
boat one has travelled 700 (rate = 700/unit time) boat two has travelled x rate = x / unit time
boat one then travels x + 400 more and boat two travels 700 + (700+x -400) more when they meet
The time is the same rate x time = distance distance/rate = time equate the distances divided by the respective rates
(700 + x + 400)/700 = ( x + 700 + (700+x-400) )/x
1100x + x^2 = 1400x + 700000
x^2-300x -700000 = 0 quadratic formula yields x = 1000
One boat travels 700 the other 1000 whe they first meet.....width of river = 700+ 1000 = 1700 m
Answer:
D
Step-by-step explanation:
The remaining material can be calculated as
volume of larger cube - volume of smaller cube
= a³ - b³ ← difference of cubes which factors in general as
= (a - b)(a² + ab + b²) → D
