The simplified form of the function will be (√10 - √10 + √15 - √21 ).

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The expression will be calculated as:-

(√2 + √3 ) ( √5 - √7 ) = √2 (√5 + √7 ) + √3 ( √5 - √7 )

= √2√5 + √2√7 + √3√5 - √3√7

= √10 + √14 + √15 - √21

Therefore simplified form of the function will be (√10 - √10 + √15 - √21 ).

A confided aquifer has a piezometric height of 30 feet before being pumped. The well is then pumped at 250 gallons/day for a ver

Karo-lina-s [1.5K]

Answer:

$d_2=-8.32ft$

Step-by-step explanation:

From the question we are told that:

Height of first draw down $h=30$

Pump Discharge $Q=250gallons/day$

Well 1 depth $d_1=10ft$

Transmissivity $\=T 10.0 ft2/day$

Radius $r=0.5$

Well 2 depth $d_2=50ft$

Generally the Thiem's equation for Discharge is mathematically given by

$Q=\frac{2\piT(h_2-h_1)}{ln(\frac{r_2}{r_1})}$

$250=\frac{2*\pi 10 (10-d_2)}{ln(\frac{50}{0.5})}$

$1151.293=2*\pi 10 (10-d_2)$

$d_2=-8.32ft$

A circle has a radius of length r. If you mark off the an arc on the circle of length 3r, what is the measurement of the angle t

prisoha [69]

Answer:

is 171.8 degrees

Step-by-step explanation:

Length of arc subtended by any angle $\alpha$ with a radius r is given by $\alpha *r$ .

For example

to calculate length of circumference

angle subtended by whole circle is 2 $\pi$

Therefore length of circumference is $2\pi *r$

Similarly we can see that for semicircle angle at center is $\pi$

hence length of arc is $\pi r$

____________________________________________

Given in the problem length of arc = 3r

radius= r

let the value of angle be $\alpha$

Plug in the value of length of arc in formula to calculate length of arc we have

3r = $\alpha* r$

$\alpha$ = 3r/r = 3

This value of angle subtended is in radian, we need to convert radian into degrees.

_____________________________________

We know that $\pi$ is equivalent to 180 degrees.

Also value of $\pi$ is 3.14

hence 3.14 radian= 180 degrees

=>3.14/3.14 = 180/3.14 ----degrees dividing both side with 3.14

=> 1 radian = 57.325 degrees

=> 1*3 radian = 57.325 * 3 degrees( multiplying both side with 3 as we need to find value of 3 radian into degrees

=> 3 radian = 171.8 degrees.

the measurement of the angle that subtended by the arc is 171.8 degrees or in radian 3 radian
