Answer:

Step-by-step explanation:

The transformation from the parent function (red line) to the blue line is a translation 2 units to the left and 3 units down, and a reflection over the x-axis.

The blue line does not seem to be stretched or compressed.

The hours of daylight,y, in Utica in days, x, from January 1, 2013 can be modeled by the equation y=3.06sin(0.017x-1.40) + 12.23

defon

The month of January has 31 days, so from January 1st to February 14th, there are 31 + 14 or 45 days, namely x = 45.

y = 3.06 * sin[ 0.017(45) - 1.40 ] + 12.23.

make sure your calculator is in Degree mode.

-7x - 12 = - 7х + 3(-4 - x)

dsp73

Answer:

$x=0$

Step-by-step explanation:

$-7x - 12 = - 7x + 3(-4 - x)$

Open up the parentheses

$-7x - 12 = - 7x -12-3x$

-7x cancels out on both sides

$-12 =-12-3x$

-12 cancels out on both sides

$0=-3x\\x=0$

I hope this helps!

The power P of a jet of water is jointly proportional to the cross sectional area A and to the cube ofthe velocity V. (a) Write

anastassius [24]

Answer:

a) $P=kAV^3$

b) 54

Step-by-step explanation:

a)

If one quantity, A, is jointly proportional to other 2 quantities (B & C), we can write proportionality equation as:

$A=k*B*C$

Where

k is the proportionality constant

Now, for this problem, P is jointly proportional to A and CUBE OF V, so we can write:

$P=kAV^3$

b)

Now velocity, V, is triples, which means it becomes 3V

Also, cross sectional area, A, is doubled, which means it becomes 2A

Let's put these into formula and see the difference:

$P=kAV^3\\P=k(2A)(3V)^3\\P=k(2A)(27V^3)\\P=(2*27)kAV^3\\P=54kAV^3$

So, power is multiplied by a factor of 54. Power becomes 54 times if Area is doubled and velocity is tripled ( as seen ).
