An object moves along a straight line so that at any time t, 0≤t≤9, its position is given by x(t)=7+6t−t2. For what value of t is the object at rest?.

Answers

We will see that for t = 3 seconds the object will be at rest.

When does an object is at rest?

We say that something is at rest if its velocity is equal to zero.

Here we know that the position equation of the object is:

x(t) = 7 + 6*t - t^2

To get the velocity, we need to differentiate with respect to the time, using the rule:

[tex]f(x) = a*x^n\\\\f'(x) = n*a*x^{n-1}[/tex]

We will get:

v(t) = 6 - 2*t

Now we just need to find the value of t such that the above equation is equal to zero:

0 = 6 - 2*t

2*t = 6

t = 6/2 = 3

Then for t = 3 seconds, the object will be at rest.

Answers

The solutions of  (93 × p) + 84 = 8593 times p plus 84 equals 85 yields  p =  84/8500 or 1/8593.

We can write the equation as follows;

(93 × p) + 84 = (8593  × p) + 84 = 85

We can solve the equation in parts as follows;

(93 × p) + 84 = (8593  × p) + 84

93p + 84 = 8593p

93p - 8593p = -84

-8500p = -84

p = 84/8500

Also;

(8593  × p) + 84 = 85

8593p + 84 = 85

p = 85 - 84/8593

p = 1/8593

Hence p = 84/8500 or 1/8593

The final scores of students in mathematics are distributed normally with a mean of 72 and a standard deviation of 10. What is the probability that a student’s score will be between 65 and 78?.

Answers

Answer:

0.8041

Explanation:

0.8041

We know that  

μ=72  and  σ=5

and P(65<X<78)

We can determine the Z value as (X-μ)/σ

P( 65<X<78 )=P( 65-72< X-μ<78-72)

P((65-72)/5 < Z < (78-72)/5)P((65−72)/5<Z<(78−72)/5)

P(65 < X < 78 )=P(-1.4 < Z < 1.2)P(65<X<78)=P(−1.4<Z<1.2)

To fine the Z values:

P (-1.4 < Z < 1.2 )=P ( Z < 1.2 )-P (Z < -1.4 )P(−1.4<Z<1.2)=P(Z<1.2)−P(Z<−1.4)

From the standard normal tables:

P (Z < 1.2 )=0.8849P(Z<1.2)=0.8849

to find P ( Z<-1.4)

P ( Z < -a)=1-P ( Z < a )P(Z<−a)=1−P(Z<a)

From the standard normal tables:

P ( Z < -1.4)=1-P ( Z < 1.4 )=1-0.9192=0.0808P(Z<−1.4)=1−P(Z<1.4)=1−0.9192=0.0808

Therefore

P(-1.4 < Z < 1.2 )=0.8041P(−1.4<Z<1.2)=0.8041

P (65 < X < 78)=0.8041P(65<X<78)=0.8041

A car travels the distance between logan airport and the town of framingham in 20 min. The logan express bus travels this distance in 30 min. After how long do the car and bus meet if they leave at the same time, and one travels from framingham to the airport while the other travels from the airport to framingham?.

Answers

The time the car and bus will meet if they leave at the same time, and one travels from Framingham to the airport while the other travels from the airport to Framingham is 12 minutes.

let

the distance between Logan airport and the town of Framingham = a

Car speed:

speed = distance / time

speed = a / 20

Logan express bus speed

speed = distance / time

speed = a / 30

let

the distance travelled by the car by the time they met = b

Then

the distance travelled by the bus the time they met = a - b

Therefore,

The time they met will be as follows:

speed  = distance / time

time = distance / speed

b / a / 20 = a - b / a / 30

20b / a = 30(a - b) / a

cross multiply

20ab = 30(a - b)a

20ab = 30a²- 30ab

50ab = 30a²

5b = 3a

b = 3 / 5 a

Therefore,

b / a / 20  =  3 / 5 a / a / 20  = 3 / 5 a × 20 / a = 60a / 5a = 12 minutes
