Let's round the numbers into perfect roots. So 23 rounded would be 25, because the square root of 25 is 5, and 47 rounded is 49, because the root of 49 is 7. So 7-5=2. That would be the best approximation for this question.

9.2cm×4cm+5cm=41.8 or 41.7cm²
Answer:
x=4
Step-by-step explanation:
x^3-4x^2-16x+64
(x^2-16)(x-4)
x-4=0
+4 +4
x=4
x^2-16=0
+16 +16
x^2=16
√ x^2=√ 16
x=4
It is 2%
I just took the quiz and yea so its 2%
Answer:
Step-by-step explanation:
You want to set up a system. We are given some points fo we can set up inputs and outputs. F(0) = 5, given by point (0,5). and F(3)=135, given by point (3,135). The exponential function general equation is F(x)= a(b)^x. plug in out functions into the general equation to get a(b)^0=5 and a(b)^3=135. Then you simplify and solve for a. In the equation a*b^0=5, anything to the power of 0 is 1. so a*1=5. Therefore a=5. we plug in the a to the second equation to find b. 5*b^3=135. b^3=27. b=3 from simplifying. Therefore, the equation should be 5(3)^x. THATS IT!
