At time tequals0, water begins to drip out of a pipe into an empty bucket. After 14 minutes, there are 7 inches of water in th

Vaselesa [24]

Answer:

$w=0.5t$

Step-by-step explanation:

Given:

'w' represents inches of water left after 't' minutes of time.

The dripping out of water is a linear function.

At time 't' equal to 0, the bucket was empty.

After 14 minutes, there are 7 inches of water in the bucket.

A linear function model is of the form: $w=mt+b$

$Where, m\to\textrm{dripping rate of water}\\b\to\textrm{water level at t=0}$

Now, at $t=0,w=0(\textrm{As bucket was empty})$

At $t=14,w=7$

Therefore, plugging these values in the above linear model and solving the system of linear equations. This gives,

$0=m(0)+b\\0=0+b\\b=0\\\\7=14m+0\\m=\frac{7}{14}=0.5\ in/min$

Therefore, the values of 'm' and 'b' are 0.5 and 0 respectively.

Thus, the linear model is given as:

$w=0.5t$

(WILL GIVE BRAINLIEST)Find the polynomial function with real coefficients that has zeros 1, 1 , 2+ i sqrt 3

neonofarm [45]

Answer:

$x^3-x^2(4+i\sqrt{3} )+x(5+i2\sqrt{3} )-(2+i\sqrt{3} )=0$

Step-by-step explanation:

We have given that this polynomial has the given zeroes of 1, 1, and $2+i\sqrt{3}$ , we can express the polynomial in a factored form where each zero has the form x-a (where a is our zero):

polynomial= $(x-1) (x-1) (2+i\sqrt{3})$

= $(x^2+1-2x) (2+i\sqrt{3})$

= $x^3-x^2(4+i\sqrt{3} )+x(5+i2\sqrt{3} )-(2+i\sqrt{3} )=0$

A boat goes 24 miles at a constant speed in 4 hours against a river current.

Ne4ueva [31]

Answer:

8 miles per hour.

Step-by-step explanation:

24miles in 4 hours = 24/4=6 miles per hour.

24 miles in 3 hours = 24/3=8 miles per hour. The boat going with the current of the river is traveling at 8 miles per hour.
