X+1+2/x add the two radical expressions

Mathematics
1 answer:
goldfiish [28.3K]3 years ago
8 0

Answer:

\frac{  \sqrt{ {x}^{2}  + x}  + 2}{ \sqrt{x} }

Step-by-step explanation:

If you are talking about radical expressions, then the two equations should be something like

\sqrt{x + 1}  +  \frac{2}{ \sqrt{x} }

Assuming this is the intended expression, then:

\frac{ \sqrt{x \times } \sqrt{x + 1}  + 2}{ \sqrt{x} }

We then simplify by collecting LCM to obtain:

\frac{  \sqrt{ {x}^{2}  + x}  + 2}{ \sqrt{x} }

A radio transmission tower is feet tall. How long should a guy wire be if it is to be attached feet from the top and is tomake a
Bond [772]

Answer:

<em> Length of guy wire is 590.6 ft</em>

Step-by-step explanation:

The complete question is

A radio transmission tower is  210  feet tall. How long should a guy wire be if it is to be attached 8 feet from the top and is to make an angle of  20°  with the ground. Give your answer to the nearest tenth of a foot.

height of tower = 210 ft

8 ft fro the top leaves 210 - 8 = 202 ft to the ground

This is an angle of elevation problem

the opposite is 202 ft

hypotenuse = ?

angle is  20°  

using sin ∅ = opp/hyp

sin  20°  = 202/hyp

0.342 = 202/hyp

hyp = 202/0.342 = <em>590.6 ft   this is the length of the guy wire</em>

ites A &amp; Bare 5 inches apart on a map. Cities &amp; Dare 4 inches apart. If C&amp;D are 900 miles apart how many miles apart
lisabon 2012 [21]

Answer:

<u>Cities A and B are 1,125 miles apart</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Distance between A and B in the map = 5 inches

Distance between C and D in the map = 4 inches

Actual distance between C and D = 900 miles

2. How many miles apart are cities A and B?

We will solve the question, using Direct Rule of Three, as follows:

Distance in the map      Actual distance

A - B      5 inches                    x

C - D      4 inches                900 miles

***************************************************

4x = 900 * 5

4x = 4,500

x = 4,500/4

x = 1,125 miles

<u>Cities A and B are 1,125 miles apart</u>
