Answer:

Step-by-step explanation:

1. Y varies jointly as R and T

Y = k*R*T

Y = kRT

Where,

k = constant of proportionality

2. B is directly proportional to the square of A and inversely proportional to the cube of C.

B = k(A²) / C³

B = kA²/C³

Where,

k = constant of proportionality

Answer:

Alright so the answer is B but I'll explain why because im nice ig.

Step-by-step explanation:

So lets do some calcumalations.

We'll use 1 as n and should get an output of 3 to check these formulas. Since 1 is the first term and 3 is the first term value makes sense alright.

So 9^1-1 is 0 and any number to the 0 power is 1 so that wont work.

3(4)^1-1 = 3(1); that's the answer

4^1-1 = 1, + 3 = 4 so that wont work either

I hope this helps ya have a great afternoon

You buy butter For $3 a pound one portion of onions compote requires 2.0ounces of butter how much does the a butter for one port

Digiron [165]

Answer:

$0.38

Step-by-step explanation:

First we need to convert pounds to ounces

1 pound = 16 ounces

Thus 16 ounces cost $3

If a portion requires two ounces of butter, we must find out the cost of these 2 ounces, knowing that 16 ounces cost $ 3

ounces cost

16 -- $3

2 -- x

To find the cost x:

$x=\frac{3*2}{16}=$0.375$

rounding to the nearest cent: $0.38

The arrow hits the top of a 3 meters tall wigwam at 0.054 seconds

<h3>How to determine the time to reach 3 meters?</h3>

The complete question is added as an attachment

The function is given as:

$h(t) = -9.8t^2 + 28t + 1.5$

Set the height to 3

$-9.8t^2 + 28t + 1.5 = 3$

Subtract 3 from both sides

$-9.8t^2 + 28t - 1.5 = 0$

Apply the following quadratic formula

$t = \frac{-b \pm \sqrt{b^2- 4ac}}{2a}$

So, we have:

$t = \frac{-28 \pm \sqrt{28^2- 4*-9.8*-1.5}}{2*-9.8}$

This gives

$t = \frac{-28 \pm \sqrt{725.2}}{-19.6}$

This gives

$t = \frac{-28 \pm 26.93}{-19.6}$

Expand

$t = \frac{-28 + 26.93}{-19.6}$ and $t = \frac{-28 - 26.93}{-19.6}$

This gives

t = 0.054 and t = 2.80

0.054 is less than 2.80

This means that the arrow hits the top of a 3 meter tall wigwam at 0.054 seconds
