A rocket is shot straight into the air at an initial velocity of 70 feet/second.

DanielleElmas [232]

Answer: 245 feet

Step-by-step explanation:

Given: The height of the rocket after t seconds is represented by the formula:

$h=70t-5t^2$

$\dfrac{dh}{dt}=70-10t$ [Differentiate both sides w.r.t. t]

Put

$\dfrac{dh}{dt}=0\\\\\Rightarrow\ 70-10t=0\\\\\Rightarrow\ t=\dfrac{70}{10}=7$

Also, $\dfrac{d^2h}{dt^2}=-10$ i.e. height is maximum at t=7.

Maximum height = $h=70(7)-5(7)^2 = 490 - 245= 245\text{ feet}$

Hence, the maximum height the rocket reaches = 245 feet.

Increase 15837.77 by 8.5% give your answer rounded to 2 D.P

artcher [175]

Given:

Increase 15837.77 by 8.5%.

To find:

The answer rounded to two decimal places.

Solution:

We have,

Initial value = 15837.77

Increasing percent = 8.5%

Now, the value after increasing by 8.5 % is

$\text{Required value}=15837.77+\dfrac{8.5}{100}(15837.77)$

$\text{Required value}=15837.77+1346.21045
$

$\text{Required value}=17183.98045
$

Round the value to two decimal places.

$\text{Required value}\approx 17183.98
$

Therefore, the required value is 17183.98.
