The easiest answer I know is if you swap the bs with xs, 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 10x^2 is wider than (5x)^2.

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.

Mr. Saba owns two food trucks. He rents two spots at the state fair. This table shows the number of tacos the two food trucks so
Nadya [2.5K]
Using the data for each truck lets calculate, 

median for truck 1 - 511.5
median for truck 2 - 650.5

lets consider each statement 
A.medians for both trucks are the same - wrong 
median for 1 and 2 are 511.5 and 650.5 respectively 

B. the two trucks sold most number of tacos on 3rd day 
truck 1 sold 437 on day 3 but highest number it sold was 721 on day 1
truck 2 sold 426 on day 3 but highest number was 732 on day 6
therefore this statement too is wrong 

C.
truck 1 - range between maximum(721) and minimum(425) = 296
truck 2 - maximum (732) and minimum (426) difference = 306
the range between maximum and minimum in truck 2 is 306 thats greater than range between maximum and minimum in truck 1, that's 296
therefore this statement is correct

D.
total number of tacos for each truck - 
truck 1 - 5291
truck 2 - 6107
food truck 1 sold less than truck 2 therefore this statement too is wrong

Help find the answer to what B is.
satela [25.4K]

Assuming that this is a right triangle, then (50 in)^2 = b^2 + (14 in)^2, according to the Pythagorean Theorem.



Then 196 in^2 + b^2 = 2500 in^2. Solving for b^2:


b^2 = (2500-196) in^2, and so b = +48 inches (answer)
