Your answer would be (x,y)=(2,-2)
In accordance with the function <em>velocity</em>, the car will have a complete stop after 6 seconds.
<h3>When does the car stop?</h3>
Herein we have a function of the velocity of a car (v), in feet per second, in terms of time (t), in seconds. The car stops for t > 0 and v = 0, then we have the following expression:
0.5 · t² - 10.5 · t + 45 = 0
t² - 21 · t + 90 = 0
By the <em>quadratic</em> formula we get the following two roots: t₁ = 15, t₂ = 6. The <em>stopping</em> time is the <em>least</em> root of the <em>quadratic</em> equation, that is, the car will have a complete stop after 6 seconds.

Answer:
55
Step-by-step explanation:
if it cost 2,145 for the whole thing and 39 for each person 2,145 divide by 39= 55
The number of the meals possible is 350.
The complete question is given below:-
A menu has 5 choices of appetizers, ten main courses, and seven desserts. How many meals are possible?
<h3 /><h3>What is the combination?</h3>
The arrangement of the different things or numbers in a number of ways is called the combination.
Given that:-
- A menu has 5 choices of appetizers, ten main courses, and seven desserts.
The number of the combination of the meals will be calculated as:-
N = 5 x 10 x 7
N = 350
Therefore the number of the meals possible is 350.

Answer:
4
Step-by-step explanation:
The computation is shown below:
Given that
There are total number of students i.e. 48
The ratio at present is 4:1
Now the computer needed to make the ratio be 3:1
So let us assume the number of students be 4x
And, the number of computers be x
So the 4x = 48
x = 12
So the computer be 12
Now the new ratio is 3:1
Students be 3x
And, computers be x
So
3x = 48
x = 16
Now the more computer needed is
= 16 - 12
= 4
hence, this is the answer but the same is not provided in the given options
