I need to know what this answer is<br><br><br>3. Write the expression 175 using radicals. ​
Rus_ich [418]

Answer:

5√7

Step-by-step explanation:

What we want to do is first just put the 175 in a sqrt like this:

√175

Next we do prime factorisation to try and simplify further.

         175

      /          \

   25            7

  /     \

5         5

We can figure out that this out √5^2 times 7

we can cancel the sqrt and the squared and simplify to 5√7

So there is your answer, 5√7.

If you have any questions feel free to ask. Also for the prime factorisation the formatting may be off, sorry for the inconvenience and have a good day!

Value of the Line integral of xe^y dx over arc of x=e^y from pt (1,0) to (e,1). Please don't bother if you don't know how to do
irina [24]
Parametize C of the line integral as
({e}^{t} ,t)
from 0<=t<1 then
dx = {e}^{t} dt
which means by substituting x with e^t and y with and dx with e^t dt we get
integral \: from \: 0 \: to \: 1( {e}^{t} \times {e}^{t} \times {e}^{t} \: dt )
by adding exponents
integrl \: from \: 1 \: to \: 0 \: of \: ( {e}^{3t}dt )
\frac{ {e}^{3} - 1}{3} - \frac{ {e}^{0} - 1 }{3}

A central angle theta in a circle of radius 7 m is subtended by an arc of length 8 m. Find the measure of theta in degrees. (Rou
gogolik [260]

Answer: In degrees , The measure of \theta=65.5^{\circ}

In radians , the measure of  \theta =\dfrac{8}{7}\text{ radians}.

Step-by-step explanation:

We know that the formula for length of arc is given by :-

l=\theta r

, where \theta = Central angle subtended by arc.

r= radius of the circle.

As per given , we have

Radius of circle : r=7 m

Length of arc : l=  8 m

Substitute these values in the above formula , we get

8=\theta (7)\\\\\Rightarrow\ \theta =\dfrac{8}{7}\text{ radians}

Hence, the measure of \theta =\dfrac{8}{7}\text{ radians}.

To convert it into degrees we multiply it with \dfrac{180^{\circ}}{\pi}

The measure of \theta =\dfrac{8}{7}\times\dfrac{180^{\circ}}{\pi}

=(\dfrac{8\times180}{7\times3.14})^{\circ}=65.5141037307^{\circ}

\approx65.5^{\circ}

Hence, the measure of \theta=65.5^{\circ}
