Exercise 1:
The exponents are wrong: when you divide two power, you subtract the exponents:
Exercise 2:
The function represents a growth rate of 300%! 3% is actually written as 0.03, so the correct function is
Exercise 3:
To factor a quadratic equation, we have to find the roots. Once you have the roots 
, you can factor the expression as 
In this case, the solutions are 
, which yields the factorization
Exercise 4:
When you multiply two powers of the same base, you add the exponents:
So, in your case, you have
Answer:
64
Step-by-step explanation:
The volume of rectangular prisms is measured by l*w*h
And by counting the units of the length, width, and height are all 4 units long.
So take the numbers and plot them into the formula
4*4*4 = V
16 * 4 = V
64 = V
The prism is 64 cubic units.
6.5% tax on $65.49=0.065×65.49=$4.26 To the nearest cent, so add this to 65.49=$69.75.
Answer:
circumference of the pizza = PI*d
using 3.14 for PI
circumference = 3.14*18 = 56.52 inches
56.52 /12 = 4.71 inches of crust
Step-by-step explanation:
Hope this helps :D
As a percentage it would be 63.5% and as a fraction it would be 635/ 1000 or 127/200
