2. You throw a softball straight up into the air at a velocity of 30 feet per second. You release the softball at a height of 5.
nadya68 [22]

Answer:

-16t^2+30t+5.8

Step-by-step explanation:

We are given that

Initial velocity=30 ft/s

Initial position=s_0=5.8 ft

We have to write a mathematical model for height of the softball by using the position equation

The position equation on Earth's surface is given by

h(t)=-16t^2+v_0t+s_0

Where v_0= Initial velocity

s_0=Initial position

Substitute the values in the equation then, we get

h(t)=-16t^2+30t+5.8

Hence, the mathematical model for height of the softball is given by

-16t^2+30t+5.8

A number line is shown. Which expression represents the distance between two points, X and Y, on the number line?
IrinaK [193]

Answer: C. |-4 - 3|

<u>Step-by-step explanation:</u>

x = -4

y = 3

The distance between them is the difference. The mathematical operation for difference is subtraction.

Distance is a unit of measurement. Measurements cannot be negative so the absolute value sign is used to ensure the difference is positive.

boyakko [2]

Answer:

  • 18x + 15y ≤ 300
  • x ≥ 0; y ≥ 6

Step-by-step explanation:

Variables are defined in the problem statement.

  18x +15y ≤ 300 . . . . total budget

  y ≥ 6 . . . . . . . . . . . .  minimum number of annuals

  x ≥ 0 . . . . . number of perennials cannot be negative

This system of inequalities describes the situation.
