Answer:

Step-by-step explanation:

Using the equation given, 2x-1, you can plug in x, which is given in the table, and solve.

13 is given for x so you plug 13 into 2x-1;

2(13)-1
26-1
25

you can then check your answer to make sure you did it correctly by plugging in another x number (such as 4) and checking to see if you get the same number as the one given.

Find the parametric equations for the line that is tangent to the given curve at the given parameter (3cost)i (t^4 -3sint)j

Answer:

Following are the solution to this question:

Step-by-step explanation:

Please find the complete question in the attached file.

In the given equation, when the point t=0

So,

$\to r(0) = (3 \cos 0)i + (0^4 - 6 \sin 0)j + (2e^{3\times 0})k)$

$= (3 \times 1)i + (0 - 0)j + (2e^{0})k)\\\\ = 3i + 0j + (2 \times 1)k)\\\\ = 3i + 0j + 2k \\$

The value of the coordinates are $3, 0, 2$ . so, the equation of the line is:

$\to \frac{(x-3)}{3 \cos \ t} = \frac{(y-0)}{(t^{4}-6 \sin \ t)} = \frac{(z-2)}{2e^{3t}}=k$

an arc welder provides 250 amps of current when operating with a voltage of 40 volts. what is the power required by this welder

FinnZ [79.3K]

The power(P) of the circuits is the product of the voltage (V) in volts and current(I) in amperes.
P = IV

Substituting the known values to the equation,
P = (250 amps) x (40 volts) = 10,000 Watts

Thus, the answer is 10,000 Watts.

Wittaler [7]

Answer:

1) 15-4x

2) 3x+2

Step-by-step explanation:

1) product of x and 4 is 4x then subtract that from 15

2) use x as your age in this situation so your age times 3 is 3x and since he's 2 years older than that u add 2 more
