<u>Answer:</u>
36° and 54°
<u>Step-by-step explanation:</u>
We are given that one of the small angles of a right angled triangle is 18 less than twice the measure of the other small angle.
We are to find the measure of both angles.
Assuming to be the other small angle, 8 less than twice the measure of the other small angle =
.
Summing all three angles up ti get:
x = 36°
So other angle will be 54°.
It takes 8.35 hours for the size of the sample to double
Step-by-step explanation:
The form of the continuous exponential growth model is
, where
- A is the new value
- P is the initial value
- r is the rate of growth or decay in decimal
- t is the time
∵ The growth rate is 8.3%
∴ r = 8.3 ÷ 100 = 0.083
∵ The size of the sample will doubled in t hours
∴ A = 2 P
Use the formula of the contentious exponential growth above
∵
- Divide both sides by P
∴
- Insert ㏑ in both sides
∴
- Remember because ㏑(e) = 1
∴
- Divide both sides by 0.083
∴
∴ t = 8.35 hours to the nearest hundredth
It takes 8.35 hours for the size of the sample to double
