It’s really simple you can just type the equation into the calculator but it’s basically 8^3 which is 8 x 8 x 8 which is 512 and divide that by 2 which is 256 and add 9 which is 265.

Step-by-step explanation:

$9 + \frac{ {8}^{3} }{2} \\ 9 + \frac{8 \times 8 \times 8}{2} \\ 9 + \frac{512}{2} \\ 9 + 256 \\ 265$

a person invest in 9000 in a bank. the bank pays 5% interest compounded semi annually. to the nearest tenth of a year, how long

QveST [7]

Answer:

10.1 years.

Step-by-step explanation:

It is given that,

Principal = 9000

Rate of interest = 5%

No. of times interest compounded = 2 times in an year

Amount after certain time = 14800

The formula for amount:

$A=P(1+\frac{r}{n})^{nt}$

where, P is principal, r is rate of interest, n is no. of times interest compounded in an year and t is time in years.

Substitute the given values in the above formula.

$14800=9000(1+\frac{0.05}{2})^{2t}$

$\frac{14800}{9000}=(1+0.025)^{2t}$

$1.644=(1.025)^{2t}$

Taking log both sides.

$\log(1.644)=\log(1.025)^{2t}$

$\log(1.644)=2t\log(1.025)$ $[\because \log a^b=b\log a]$

$\frac{\log(1.644)}{2\log(1.025)}=t$

$t=10.066$

$t=10.1$

Therefore, the required time is 10.1 years.

Use Pythagorean Theorem to solve for x.<br><br> HELP ME PLZZZZ!!!! ASAP

4vir4ik [10]

Answer: $2\sqrt{22}$

Step-by-step explanation:

Pythagorean theorem: $a^{2} +b^{2} = c^{2}$ , where a and b are the legs and c is the hypotenuse.

We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.

$9^{2} +b^{2} = 13^{2}$
