It will take the inattentive driver 5.22 seconds to come to a complete stop, assuming the car's deceleration remains constant.
An inattentive driver traveling 16.0 m/s when he notices a red light ahead and his car is capable of decelerating at a rate of \(3.06 m/s^2\). To determine how much time it will take for the car to come to a complete stop, we can use the following equation of motion:
v = v0 + at
where v is the final velocity (in this case, 0 m/s), v0 is the initial velocity (16.0 m/s), a is the acceleration (negative, because the car is slowing down), and t is the time.
Rearranging and solving for t, we get:
t = -v0 / a
t = -16.0 / (-3.06)
t = 5.22 seconds
So, it will take the inattentive driver 5.22 seconds to come to a complete stop, assuming the car's deceleration remains constant. This time can be used to determine the minimum distance the driver needs to maintain between himself and the vehicle in front of him to avoid a collision.

Answer:
x + (4/ x-2) + (2/ x-1)
Step-by-step explanation:
x + (6x/ x^2 + 2x - x -2)
x + (6x/ (x + 2) X (x - 1))
(6x/ (x + 2) X (x - 1))
(A/ x+2) + (B/ x-1)
(6x/ (x + 2) X (x - 1)) = (A/ x+2) + (B/ x-1)

Find the area of the curve y= f(x) = x between x = 5 and x = 10
Answer:
the area of the curve y= f(x) = x between x = 5 and x = 10
\(A=\frac{75}{2}\)
Step-by-step explanation:
Finding the area of the curve y = f(x) = x between x = 5 and x = 10Using the Area formula
\(A=\int _a^b\:f\left(x\right)dx\)
As the area of curve lies between x = 5 and x = 10
so
a = 5, b = 10so the integral expression becomes
\(A=\int _5^{10}xdx\)
\(\mathrm{Apply\:the\:Power\:Rule}:\quad \int x^adx=\frac{x^{a+1}}{a+1},\:\quad \:a\ne -1\)
\(A=\left[\frac{x^{1+1}}{1+1}\right]^{10}_5\)
\(=\left[\frac{x^2}{2}\right]^{10}_5\)
\(=\frac{1}{2}\left[10^2-5^2\right]\)
\(=\frac{1}{2}\cdot \:75\)
\(=\frac{75}{2}\)
Therefore, area of the curve y= f(x) = x between x = 5 and x = 10
\(A=\frac{75}{2}\)
25x + 10y = 600

Students put 2 1/4 pounds of trail mix into bags that each weigh 3/8 pounds. They bring 2/3 of the bags of trail mix on a hiking trip. Can you determine how many bags of trail mix are left by just completing one step?
There are 4 bags left after completing one step
The number of bags left after completing one step can be calculated as follows
The amount of trail mix into the bags is 2 1/4
= 9/4
The total amount of trail mix in the bag is 2/3
The first step is to calculate the number of bags
= 9/4 ÷ 3/8
= 9/4 × 8/3
= 36/12
= 6
There are 2/3 bags of trail
= 2/3 × 6
= 4
Hence 4 bags of trail mix are left after completing one step

Pizzazz 164 answers???? What do you call it when someone pays back a loan quickly
Answer: A sudden debt pay off
Step-by-step explanation:
A loan in this context is a specific amount of money that is borrowed to be paid back with interest. The lender is usually an individual, financial organizations or the government.
The lender and the borrower both share the terms of agreement which includes interest rates, date of payments and other stipulated conditions.
When a borrower pays a loan quickly, it is known as Sudden Debt Payoff.
This is because the borrower pays back before the date that both parties agreed on.

You are the owner of four Taco Bell restaurant locations. You have a business loan with Citizens Bank taken out 60 days ago that is due in 90 days. The amount of the loan is $50,000, and the rate is 9.5% using ordinary interest.
You currently have some excess cash: $35,000. Due to situations beyond your control, you, as the owner, must make an immediate business decision now to pursue only one of these two choices:
1) sending all of the $35,000 to Citizens Bank as a partial payment on your loan, or
2) using the $35,000 to purchase serving supplies such as food containers, cups, and plastic dinnerware for your inventory. This is the last day to take advantage of the opportunity to save some money due to a special discount price that is "10% off" the normal cost of $35,000 for these items.
Consider these calculations:
(a)
How much interest (in $) will you save on this loan if you make the partial payment and don't purchase the additional serving supplies? (Round your answer to two decimal places.)
$
(b)
How much money (in $) will you save if you purchase the serving supplies with the discount and don't make a partial payment on the loan? (Round your answer to two decimal places.)
$
(c)
How much (in $) will you save by purchasing the discounted serving supplies rather than making the partial payment? (Hint: Find the difference between the savings on the supplies found in part (b) and the savings on the loan interest found in part (a). Round your answer to two decimal places.)
$
(d)
What other factors should you consider before making this decision?
The amount saved by repaying the loan early is $831.25
The amount of discount received by purchasing supplies is $3,500
The net amount saved by purchasing supplies rather than repaying loan is $2,668.75
What is ordinary interest?
Ordinary interest is the interest computation that is based on 360-day a year count rather than 365-day year count, hence, in determining the amount saved by paying $35,000 out of the amount due to Citizens Bank, we time-apportion the interest for 90 days with respect to 360 days not 365 days.
Amount saved in interest=$35,000*9.5%*90/360
Amount saved in interest=$831.25
Using the $35,000 to purchase serving supplies, 10% discount is given off the normal cost of $35,000
Amount saved with discount=10%*$35,000
Amount saved with discount=$3,500
The difference between discount on supplies and interest saved=$3,500-$831.25
The difference between discount on supplies and interest saved=$2,668.75
The other factors to consider before making the final decisions include, the fact the loan is more important than the supplies because the loan relates to the firm's financing rather than operational needs of supplies
Secondly, the amount saved in interest may be more if another loan of $35,000 can be borrowed elsewhere with significant lower interest rates

if the mean of x,x+3,x-5,2x and 3x then find the value of x
The Value of x is 2/3.
The value of x, we need to determine the mean of the given values and set it equal to the expression for the mean.
The mean (average) is calculated by adding up all the values and dividing by the number of values. In this case, we have five values: x, x+3, x-5, 2x, and 3x.
Mean = (x + x+3 + x-5 + 2x + 3x) / 5
Next, we simplify the expression:
Mean = (5x - 2 + 3x) / 5
Mean = (8x - 2) / 5
We are given that the mean is also equal to x:
Mean = x
Setting these two expressions equal to each other, we have:
(x) = (8x - 2) / 5
To solve for x, we can cross-multiply:
5x = 8x - 2
Bringing all the x terms to one side of the equation and the constant terms to the other side:
5x - 8x = -2
-3x = -2
Dividing both sides by -3:
x = -2 / -3
Simplifying, we get:
x = 2/3
Therefore, the value of x is 2/3.

What is the equation in point slope form of the line that is perpendicular to the given line and passes through the point(2,5)?
Answer:
Step-by-step explanation:
To find the equation of a line that is perpendicular to a given line and passes through a specific point, we need to follow a few steps:
Find the slope of the provided line.
The point-slope form of a line is given by: y - y1 = m(x - x1), where (x1, y1) represents the given point.
Substituting the values, the equation of the perpendicular line becomes:
y - 5 = (-1/m)(x - 2)
Simplifying the equation further, we can rewrite it in point-slope form:
y - 5 = (-1/m)x + (2/m)

Using alternative form of the definition of derivative.
f'(a) = lim (h->0) [f(a+h) - f(a)] / h
Using this formula for the given function;
h'(a) = lim (h->0) [h(a+h) - h(a)] / h
Now, substitute a = -6 into the formula:
h'(-6) = lim (h->0) [h(-6+h) - h(-6)] / h
Next, simplify the expression by plugging in the values:
h'(-6) = lim (h->0) [1/(-6+h) + 3 - (1/-6 + 3)] / h
Simplifying further:
h'(-6) = lim (h->0) [1/(-6+h) - 1/-6] / h
Now, let's combine the fractions with a common denominator:
h'(-6) = lim (h->0) [(-6 - (-6+h))/((-6+h)(-6))] / h
Simplifying the numerator:
h'(-6) = lim (h->0) [-h / ((-6+h)(-6))] / h
Canceling out the h's:
h'(-6) = lim (h->0) [-1 / ((-6+h)(-6))]
Taking the limit as h approaches 0:
h'(-6) = -1 / ((-6)(-6))
Simplifying further:
h'(-6) = -1 / 36
