Left parenthesis 5 plus 2 square root of 6 right parenthesis squared = a plus b square root of 6 then the value of a and b are

Ganezh [65]

Answer:

The values of $a$ and $b$ are $33$ and $\frac{20\sqrt{3}}{3}$ , respectively.

Step-by-step explanation:

The statement is equivalent to the following mathematic expression:

$\left(5 + 2\sqrt{2})^{2} = a + b\cdot \sqrt{6}$ (1)

By definition of the perfect square trinomial:

$25 + 20\cdot \sqrt{2} + 8 = a + b\cdot \sqrt{6}$

$33 + 20\sqrt{2} = a + b\cdot \sqrt{6}$

And by direct comparison we have the following system:

$a = 33$ (2)

$b\cdot \sqrt{6} = 20\sqrt{2}$ (3)

By (3), we solve for $b$ :

$b = \frac{20}{\sqrt{3}}$

$b = \frac{20\sqrt{3}}{3}$

The values of $a$ and $b$ are $33$ and $\frac{20\sqrt{3}}{3}$ , respectively.

Surveyors wished to know the distance across a lake between A and B. They measured the distance from B to C as 100 m and the ang

Answer:

Step-by-step explanation:

Check the attachment for the diagram.

You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;

tan 35° = opposite/adjacent

tan 35° = AB/BC

tan 35° = AB/100

AB = 100tan35°

AB = 100 * 0.7002

AB = 70.02m

Hence the distance across a lake between A and B is approximately 70m

Alexis put $2000 in a savings account. After 4 years, she had $2543 in the account. What rate of interest did she earn? Use the

natta225 [31]

Alrighty

P=2000
A=2543
t=4

$A=Pe^{rt}$
$2543=2000e^{4r}$
solve

$2543=2000e^{4r}$

divide both sides by 2000

$\frac{2543}{2000}=e^{4r}$

take ln of both sides

$ln(\frac{2543}{2000})=ln(e^{4r})$

$ln(\frac{2543}{2000})=(4r)ln(e)$

$ln(\frac{2543}{2000})=(4r)(1)$

$ln(\frac{2543}{2000})=4r$

divide both sides by 4

$\frac{ln(\frac{2543}{2000})}{4}=r$

use your calculator

0.060049=r
convert to percent
that is about 6%

the interest rate is 6%
