<u>Given</u>:

The height of an object project upward is given by the polynomial

h=-16t^2+60t+90

where t represents the time, in seconds.

We need to determine the height after t = 2.5 seconds.

<u>Height of an object:</u>

The height of an object after 2.5 seconds can be determined by substituting t=2.5 in the polynomial, we get;

h=-16(2.5)^2+60(2.5)+90

Simplifying, we get;

h=-16(6.25)+60(2.5)+90

h=-100+150+90

h=140

Thus, the height of an object is 140 feet.

R+6≥11 ; {4,5,6,7}<br><br> Answer choices: 4, 5, 6,7
Alex_Xolod [135]

For this case we have the following inequality:

r + 6 \geq11

To solve we have:

Subtracting 6 from both sides of the equation:

r \geq11-6\\r \geq5

Thus, the solution is given by all values of r greater than or equal to 5.

Answer:

The solution is given by all values of r greater than or equal to 5.
