Answer:
Step-by-step explanation:
Given the expression 
, to evaluate this, we will use one of the law of indices as shown;
Mario's error was that she did not raise the value of 4 to the power of -3. She only raised z^8 to the power of -3 when it is supposed to affect both 4 and z^8
Answer:
7.5 metres
Step-by-step explanation:
The formula for the area of a parallelogram is Area = base x height.
In the problem, you are given the base, which is 9.44 metres, and the area, which is 70.8 square metres.
When you plug everything into our area formula, you should get:
70.8 = 9.44 x height
To solve for height, you would divide both sides by 9.44.
70.8 ÷ 9.44 = height
7.5 = height
Don't forget your units, which is <u>metres</u>!
height = 7.5 metres
Answer:
(a) 1.54 seconds, -0.26 meters
(b) approach 3 meters
Step-by-step explanation:
(a) The value of x that minimizes height is 1.54 seconds.
The minimum height is -0.26 meters.
__
(b) For large x, the height appears to asymptotically approach 3 meters.
10 and 40 are the awnsers ten bring that times 4 is 40 plus 10
Because all the digits are the same, each digit is worth 10x the one to its right and 1/10 of the one to its left.
This is because we count in base 10. This is also why we can expand this number to become
9*10^6+ 9*10^5+ 9*10^4+ 9*10^3+ 9*10^2+ 9*10^1 +9*10^0.
Hope this helps!
