Nts 3. By experiments, it is found that the most efficient pedestrian tunnel is given by:
y=-0.04x² +0.88x where the floor of the tunnel is along the x-axis beginning at the origin. The
height and width of the tunnel is measured in meters. Determine the maximum height and width
of the tunnel.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%

step-by-step explanation:

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
