An object's position is given by x(t) = 5 + 10 t 2. what is its acceleration after 5 s
The acceleration after 5 seconds is 20 m/s^2.
Explanation:To find the acceleration, we need to take the second derivative of the position function.
x(t) = 5 + 10t^2
Taking the derivative with respect to time, we get:
v(t) = 20t
Taking the derivative again, we get the acceleration:
a(t) = 20
Therefore, the acceleration after 5 seconds is 20 m/s^2.

Which three statements would produce the truth value F when p is true and q is false?
A. p -> q
B. ~p/\~q
C. p->~q
D. q\/~p
C. p/\~q
please help
Answer with Step-by-step explanation:
p is true then ~p is false.
q is false then ~q is true.
A. p -> q
if p is true and q is false then this gives false truth value.
Hence, here truth value is F
B. ~p/\~q
if any one of them is false then it gives false truth value.
Hence, here truth value is F(since,~p is false)
C. p->~q
true statement implies a true statement hence, truth value will be true
Hence, here truth value is T(p true implies ~q true)
D. q\/~p
if any one of them is true then compound statement is true.
Hence, here truth value is F(since, ~p and q both are false)
E. p/\~q
if both true then compound statement is also true.
Hence, here truth value is T(since p and ~q both are true)

Nicholas volunteers at a local soup kitchen and he notices how quickly the kitchen is going through its stock of canned goods. Below is the graph representing the data Nicholas found. Find the slope and y-intercept of the line.
Answer:
m=-63 b=825
Step-by-step explanation:
The slope of the line would be - [m] = - 63 and the [y] intercept is - [c] = 835.
What is the general equation of straight line? What is a mathematical function, equation and expression?straight line : The general equation of a straight line is -[y] = mx + c
function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that Nicholas volunteers at a local soup kitchen and he notices how quickly the kitchen is going through its stock of canned goods.
It is given that a graph has number of days on the x - axis and number of canned goods on the y-axis. The line goes through points (2, 699) and (8, 321). The slope of the line can be written as -
[m] = (321 - 699)/(8 - 2)
[m] = -378/6
[m] = - 63
For the point (2, 699), we can write -
y = - 63x + c
699 = - 63 x 2 + c
699 = -126 + c
c = 699 + 126
c = 835
Therefore, the slope of the line would be - [m] = - 63 and the [y] intercept is - [c] = 835.

For what values of a and b is the line 2x + y = b tangent to the parabola y = ax2 when x = 2?
The equation of the parabola is y = ax² = (-1/2)x² where a = -2 and b = -8 are the required values of a and b.
What is the slope of the tangent line?The first derivative of y = ax² that represents the slope of the tangent line to the curve of y = ax² .
Here, dy/dx = 2ax.
When x = 2,
dy/dx = 2a(2) = 4a.
The point of tangency is (2,y), where y = a(2)², or y=4a;
thus, the point of tangency is; (2, 4a).
The equation of the tangent line to y=ax² at (2,4a)
Now differentiating y=ax² with respect to x,
dy/dx = 2ax
dy/dx (at 2,4a) = 2a(2) = 4a
The line 2x + y = b is tangent to y = ax² at (2,4a).
The slope of 2x + y = b can be found by solving 2x + y = b for y:
y = b - 2x
Slope m = -2
Thus, dy/dx = 4a = - 2, and thus a = -2/4, or a = -1/2. All we have to do now is to find the value of b.
We know that 2x + y = b, then if x=-2 and y=-8,
2(-2) + [-8] = b = -4 - 8 = -12
Thus, the equation of the parabola is y = ax² = (-1/2)x² where a = -2 and b = -8 are the required values of a and b.

A school conference room can seat a maximum of 83 people. The principal and two counselors need to meet with the school’s student athletes to discuss eligibility requirements. If each student must bring a parent with them, what is the maximum number of students that can attend each meeting?
Answer:
The maximum number of students that can attend each meeting is:
40
Step-by-step explanation:
A school conference room can seat a maximum of 83 people.
The principal and two counselors need to meet with the school’s student athletes to discuss eligibility requirements.
Let there be x students,there will be x parents
that means x+x+3≤83
Subtracting both sides by 3,we get
2x≤80
dividing both sides by 2,we get
x≤40
Hence, the maximum number of students that can attend each meeting is:
40

What is the rounding off numbers?Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.
In the given number, digit in the tens place is 2, so the number rounded to nearest hundred as 1500.
Therefore, Julia and Kim round the number of pages to the nearest hundred as 1500.

You make a large bowl of salad to share with your friends. Your brother eats 1/3 of it before they come over. What fractional portion of the original bowl of salad does each friend receive?
Answer:
[tex]\frac{2}{3x}[/tex]
Where, x = total friends
Step-by-step explanation:
Given,
The part of the salad has eaten = [tex]\frac{1}{3}[/tex]
Total part of the salad = 1,
Thus, the remaining part of the salad = original part - part has eaten
[tex]=1-\frac{1}{3}[/tex]
[tex]=\frac{3-1}{3}[/tex]
[tex]=\frac{2}{3}[/tex]
If there are x friends,
Then the portion of the original bowl of salad received by each friend
[tex]=\frac{\text{Remaining part}}{\text{Total friends}}[/tex] [tex]=\frac{2}{3x}[/tex]
A geologist have two rocks on a scale that weighs 2 1/2 lbs together rock a was 1/7 of a the total weight how much did rock a weight
By using the given fraction of rock 'a' against the total weight of two rocks, we can find that rock 'a' weighs approximately 0.357 lbs.
Explanation:The student's question involves calculating the weight of a rock, given as a fraction of a total weight. In this case, they are talking about a scenario where a geologist uses a scale to weigh two rocks together, with a total weight of 2 1/2 lbs, and rock 'a' is specified to be 1/7 of this total weight. To determine the weight of rock 'a', we simply divide the total weight by 7.
So, 2 1/2 lbs is equivalent to 2.5 lbs (since 1/2 is the same as 0.5). To find the weight of rock 'a', we take this total weight and perform the operation: 2.5 ÷ 7 = 0.357 lbs.
Therefore, rock 'a' weighs approximately 0.357 lbs. Remember, this is an estimation because the weight of the rock is being given as a fraction of the total weight, and actual weights can vary based on factors such as density and volume.
