$600 invested at 5% compounded daily after a period of 3 years.
alisha [4.7K]

Answer:

$697.09

Step-by-step explanation:

The computation of the investment after 3 years is shown below:

As we know that

Amount = Present value × (1 + rate)^number of years

= $600 × (1 + 0.05 ÷ 365)^365× 3

= $697.09

Hence, the investment after 3 years is $697.09

We simply used the above formula to determine the investment

(ii) A peacock is sitting on the tree and observes its prey on
Paraphin [41]

Answer:

74.8 m

Step-by-step explanation:

We are given that

\theta=22^{\circ}

Speed of peacock,v=10 km/h

Time,t=1 min 12 sec=60+12=72 s=\frac{72}{3600}=0.02 h

1 hour=3600 s

Distance=vt=10\times 0.02=0.2 km=0.2\times 1000=200 m

Using 1 km=1000 m

We know that

sin\theta=\frac{Perpendicular\;side}{hypotenuse}

Using the formula

sin22=\frac{h}{200}

h=200sin22=200\times 0.374=74.8 m

Hence, the peacock was at height  of 74.8 m on the tree.

A college uses the formula T(c)=4000+95c to determine the quarterly tuition, T, to charge students taking c credits.
Trava [24]

Answer:

a) y-intercept is 4000

b)T(18)=5710

Step-by-step explanation:

a) This is the equation of a line with slope 95 and y-intercept 4000.

The y-intercept represents the basic amount the student has to pay even if not taking any unit: $4000

b) T(18) represents the total amount to be paid by a student who is taking 18 units: T(18) = 4000 + 95*18 = 4000 + 1710 = 5710

So a total tuition of $5710
