Step-by-step explanation:
((7²-2×7×3+3²)/8)-1=( 16/8)-1=2-1=1
Answer: 77.11110
Step-by-step explanation:
Answer:
0.1kg
Step-by-step explanation:
the scale that is measuring the weight can only measure to a precision of 0.1kg. if the measurement was 48.65, then the precision is 0.01kg.
The answer is 8 Feet i think
The easiest answer I know is if you swap the 
s with 
s, then there will be two equations called parabolas. They open upward if the value is positive and open downward if the value is negative. If the exponent is 2, then it's a parabola. If it's 3, then it's a cubic function, because cube is for "3". Square is for "2". If you look at both parabolas, you can see that 
is wider than 
.
So the best answer I can think of is She made a mistake because the parabola on the 10x² graph is wider than the (5x)² graph. Also, it's because 5x and 10x are not the same thing. When an x value increases, the graph is narrower.
