A town has accumulated 5 inches of snow, and the depth is increasing by 6

satela [25.4K]

Answer:

Therefore, after 1 hour and 20 minutes, the snowfall in both cities was equal to 13 inch.

Step-by-step explanation:

Calculating the depth of First Town:

First town has accumulated 5 inches of snow.

As the depth is increasing by 6 inches every hour

i.e. 6 inch = 1 hour

so the depth increase after 45 minutes i.e. 3/4 hour = 4.5 inch

After 45 minutes

Snow level of First town after 45 min = 4.5 + 5 = 9.5 inch

After 1 hour

Snow level of First town after 1 hour = 5 + 6 = 11 inch

After 1 hour and 20 minutes

5 + 6 + 2 = 13 inch ∵ If 6 inch per hour, then 2 inch in 20 min

Calculating the depth of Second Town:

Second town has accumulated 9 inches of snow.

As the depth is increasing by 3 inches every hour.

i.e. 3 inch = 1 hour

so the depth increase after 45 minutes i.e. 3/4 hour = 2.25 inch

After 45 minutes

Snow level of Second town after 45 min = 9 + 2.25 = 11.25 inch

After 1 hour

Snow level of Second town after 1 hour = 9 + 3 = 12 inch

After 1 hour and 20 minutes

Snow level of Second town after 1 hour and 20 minutes

9 + 3 + 1 = 13 inch ∵ If 3 inch per hour, then 1 inch in 20 min

From the above observation, it is clear that after 1 hour and 20 minutes the snowfall in both cities was equal.

Therefore, after 1 hour and 20 minutes, the snowfall in both cities was equal to 13 inch.

A bridge is sketched in the coordinate plane as a parabola represented by the equation h=40-0.01x2, where h refers to the height

ElenaW [278]

Answer:

The length of the bridge is 126.492 feet.

Step-by-step explanation:

Let $h(x) = 40-0.01\cdot x^{2}$ , where $x$ is the position from the middle of the bridge, measured in feet, and $h(x)$ is the height of the bridge at a location of x feet, measured in feet. In this case, the length of the bridge is represented by the distance between the x-intercepts of the parabola, which we now find by factorization:
