Time taken for the amount deposited to grow to $5000 will be found as follows:
A=P(1+r/100*n)^nt
where:
A=amount
P=principle
r=rate
n=number of terms
t=time
thus plugging in our values we have:
5000=3587.39=(1+4.2/200)^2t
solving for t we have:
1.393771=1.021^2t
2t=ln1.393771/ln1.021
2t=16.111
t=8.055685 years~8 years
Answer:
- 2⁻⁶
Step-by-step explanation:
To simplify this we have to know the following rules.
(i) (xᵃ)ᵇ = xᵃᵇ
(ii) 1/xᵃ = x⁻ᵃ
Given: 
= 
=
=
[using (i)]
=
[using (ii)]
Hence, the simplified form would be: 
Answer:
Step-by-step explanation:
<u>Area of the larger circle:</u>
<u>The shaded area:</u>
- π(2r)² - πr² = 75
- 3πr² = 75
- πr² = 25
<u>Area of the larger circle:</u>
Answer:
B= 21° C= 29°
Step-by-step explanation:
Use sin rule.
1st one.
sin44°/33 = sinB/17
sinB= 17sin44/33
B= sin^-1 ( ans)
B= 20,97 =21°
2nd one.
sin92°/35 = sinC/17
sinC = 17sin92°/35
C= sin^-1 (ans)
C= 29,04° = 29°
