To find 5, Beau found 22 = 4 and 32 = 9. He said that since 5 is between 4 and 9, 5 is between 2 and 3. Beau thinks a good estim

Complete question

To find \sqrt{5} , Beau found 2^2 = 4 and 3^2 = 9 . He said that since 5 is between 4 and 9, \sqrt{5}, is between 2 and 3. Beau thinks a good estimate for \sqrt{5} , is \frac{2 + 3}{2} =  2.5 Is his estimate high or low? How do you know?

Answer:

The estimation is high because 5 is very close to 4 so \sqrt{5} will also be very close to \sqrt{4} which is lower than the estimate

In order to get a good estimate

The first step is to choose a number between 2 and 3 let say 2.8 , 2,85 , 2.9 and the square them

i.e

2.1^2 =  4.41

     2.2^2 =  4.84

      2.3^2 =  5.29

From here we can see that \sqrt{5}  lies between 2.2 and 2.3 but is closer to  2.2

So a good estimate for \sqrt{5} is 2.2

Two sides of a triangle measure 8 ft and 12 ft, respectively. The included angle is 65˚. Approximately how long is the third sid
Virty [35]

Answer:

Approximately 11 feet.

Step-by-step explanation:

Let the length of the third side of the triangle be represented by x. Applying Cosine rule, we have:

c^{2} = a^{2} + b^{2} - 2abCos C

⇒ x^{2} = 8^{2} + 12^{2} - 2(8 x 12) Cos65^{o}

       = 64 + 144 - 192 x 0.42262

       = 208 - 81.143

       = 126.857

x = \sqrt{126.857}

  = 11.2631

x ≅ 11

The length of the third side of the triangle is approximately 11 feet.

gina has 250 in her saving account she puts in 4% of her monthly paycheck of 3,100 each month rodger has 350 in his savings acco
Sidana [21]

<u>Answer:</u>

3 months

<u>Explanation: </u>

Amount saved in Gina’s saving account= 250

Amount Gina puts  in her account each month= 4% of 3100

=\frac{4}{100} \times 3100

= 4 × 31

= 124

Hence total amount  added in each month =124

Therefore money credited x months

= 250 + 124 x

Amount saved in Rodger’s account = 350

Amount Rodger puts in his account each month = 3% of 2900

=\frac{3}{100} \times 290

=87

Hence total amount added in each month = 87

Therefore money credited x months

=350 + 87 x

Now to calculate the nearest month when Gina have more in her account than Rodger does

=Amount of money credited in x months in Gina’s account ≥  Amount of money credited in x months in Rodger’s account

=250+124 x ≥ 350+87 x

=37 x≥100

= x≥2.78

=3
