Suppose that a particle following the given path c(t) flies off on a tangent at t = t0. Compute the position of the particle at

the given time t1. c(t) = (2t2, t3 − 4t, 0), where t0 = 3, t1 = 4

4 0

Answer:

(30,35,0)

Step-by-step explanation:

We are given that

C(t)=(2t^2,t^3-4t,0)

t_0=3,t_1=4

The velocity of particle,v(t)=c'(t)=(4t,3t^2-4,0)

Substitute t_0=3

C(3)=(2(3)^2,(3)^3-4(3),0))=(18,15,0)

v(3)=(4(3),3(3)^2-4,0)=(12,23,0)

The tangent line at t=3 is given by

l(t)=c(2)+(t-3)v(3)=(18,15,0)+(t-3)(12,23,0)

Now, substitute t=4

l(4)=(18,15,0)+(4-3)+(12,23,0)=(18,12,0)+(12,23,0)

l(4)=(30,35,0)

Hence, the position of particle  at t_1=4=(30,35,0)

Solve a) 2(x+3)=x-4 b) 4(5x-2)=2(9x+3)
Nat2105 [25]

Answer:

a) -10 b) 7

Step-by-step explanation:

a) 2(x+ 3) = x - 4

2x + 6 = x - 4

2x - x = -6 - 4

x = -10

b) 4(5x - 2) = 2(9x + 3)

20x - 8 = 18x + 6

20x - 18x = 6 + 8

2x = 14

x = 14/2

x = 7

Twenty-two more than a number is 47
Karo-lina-s [1.5K]

Answer:

the number is 25

Step-by-step explanation:

If the number is n, then twenty-two more is n + 22

which equals 47, so n+ 22 = 47

n = 47 - 22 = 25

The time taken for the population of the pig to reach 1000 will be almost four years.

<h3>What is a function?</h3>

A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.

Six guinea pigs are released in an area with no natural predators.

The guinea pig population quadruples every year.

Write a function P that represents the guinea pig population at a given time T measured in years.

Then the function will be

\rm P = 6 (4)^T

Then the inverse function of P will be

\rm T = 6 (4)^P\\\\\\P \ln 4 = \ln \left (\dfrac{T}{6} \right )\\\\\\P = \dfrac{\ln (T/6)}{\ln 4}

Then the time taken for the population of the pig to reach 1000 will be

\rm 1000 = 6 (4)^T\\\\\\166.667 = 4^T\\\\\\T = 3.69 \\\\\\T \approx 4 \ years

More about the function link is given below.
