Answer:
p=4
Step-by-step explanation:
first change all the addition signs in to minus if the numbers are negative. ex. p+-8 = p-8.
So the equation equals to -2(p-8)-2=6.
Next +2 to both sides to cancel out the -2 and you get -2(p-8)=8
Divide both sides by -2 and you get (p-8)=-4. At this point you can remove the parenthesis. So the equation is p-8=-4
Finally +8 to both sides and you get p=4
1 meter is greater then 83 cm Because if you divide it will be 0.83 and the differences will be 0.17
Answer:
The rocket hits the ground at a time of 11.59 seconds.
Step-by-step explanation:
The height of the rocket, after x seconds, is given by the following equation:
It hits the ground when 
, so we have to find x for which , which is a quadratic equation.
Finding the roots of a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots 
such that 
, given by the following formulas:
In this question:
So
Since time is a positive measure, the rocket hits the ground at a time of 11.59 seconds.
The intersection of two sets is a set that contains elements that are common to both sets.
There are no common elements in sets E and F, so the answer is the empty set.
<span>E ∩ F = { }</span>
