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.

A 90-kg astronaut biologist searches for microbial life on Mars where the gravitational acceleration is g = 3.71 m/s2. What is t

Yuki888 [10]

M = 90 kg,
On Mars: g = 3.71 m/s²
Weight = m · g = 90 kg · 3.71 m/s² = 333.9 N
1 N = 0.2248 lbf
333.9 · 0.2248 = 75.06072 lbf ≈ 75 lbf

4 times a number plus 16 is more than 28.

umka21 [38]

4*4= 16 + 16= 32 :) You could do 4 * 4 that equals 16 then add 16 to that to get over 28.

What is the image point of (4, -6) after a translation right 5 units and<br> up 4 units?

Ivan

Answer:

Coordinate point of the image is (9, -2)

Step-by-step explanation:

In the coordinate point (4, -6);

=> x-value = 4

=> y-value = -6

We know that the translation of;

=> 5 units right would add 5 to the x-value

<em>(x) + 5</em> = (4) + 5
9 <= This is the x-value of the image being created by the translation.

=> 4 units up would add 4 to the y-value

<em>(y) + 4</em> = (-6) + 4
-2 <= This is the y-value of the image being created by the translation.

Therefore the answer; (x, y) => (9, -2)

Hope this helps!
