A car is being driven at a rate of 40 ft/sec when the brakes are applied. The car decelerates at a constant rate of 10 ft/sec2.
IRISSAK [1]

Answer:

80 feet

Step-by-step explanation:

Given:

Initial speed of the car (v_0) = 40 ft/sec

Deceleration of the car (\frac{dv}{dt}) = -10 ft/sec²

Final speed of the car (v_x) = 0 ft/sec

Let the distance traveled by the car be 'x' at any time 't'. Let 'v' be the velocity at any time 't'.

Now, deceleration means rate of decrease of velocity.

So, \frac{dv}{dt}=-10\ ft/sec^2

Negative sign means the velocity is decreasing with time.

Now, \frac{dv}{dt}=\frac{dv}{dx}(\frac{dx}{dt}) using chain rule of differentiation. Therefore,

\frac{dv}{dx}\cdot\frac{dx}{dt}= -10\\\\But\ \frac{dx}{dt}=v.\ So,\\\\v\frac{dv}{dx}=-10\\\\vdv=-10dx

Integrating both sides under the limit 40 to 0 for 'v' and 0 to 'x' for 'x'. This gives,

\int\limits^0_{40} {v} \, dv=\int\limits^x_0 {-10} \, dx\\\\\left [ \frac{v^2}{2} \right ]_{40}^{0}=-10x\\\\-10x=\frac{0}{2}-\frac{1600}{2}\\\\10x=800\\\\x=\frac{800}{10}=80\ ft

Therefore, the car travels a distance of 80 feet before stopping.

Factor this completely
bezimeni [28]

28n^4 +16n^3 -80n^2  

we can factor out a 4n^2

In a bowl of fruit there are 10 bananas, 6 apples and 4 pears.
kobusy [5.1K]

Answer:

P(0,0) = 2/12 times 1/11 = 1/66

Step-by-step explanation:

For probability questions, think of each event happening separately, it makes the maths easier to understand. For example, in this question, do not think of the two boys taking a fruit at the same time - that makes the maths complicated

.

Let Daniel take a fruit first, then Sean can take a fruit. There are two parts to consider.

P

r

o

b

a

b

i

l

i

t

y

=

number of desirable outcomes

total number of possible outcomes

For Daniel: there are 12 different pieces of fruit in the bowl, he just takes one without choosing a specific fruit. (random)

The chance that Daniel takes an orange is

2

12

Of the 12 pieces of fruit. 2 are oranges.

Now Sean: the numbers of fruit in the bowl have changed. There are now only 11 pieces of fruit in the bowl, and only 1 is an orange.

The chance that Sean takes an orange is

1

11
