Answer:

$11,500 was invested at 13%.

$17,500 was invested at 4%

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P

In this question:

Loans totaling 29,000.

P was invested at 13%

29000 - P was invested at 4%.

First investment:

Principal P.

Interest 13% = 0.13.

One year, so t = 1.

So

E_{1} = P*0.13*1

E_{1} = 0.13P

Second investment:

Principal 29000 - P.

Interest 4% = 0.04.

One year, so t = 1.

So

E_{2} = (29000-P)*0.04

The total interest earned for both loans was $2,195.00.

This means that E_{1} + E_{2} = 2195

So

E_{2} = 2195 - E_{1}

So we solve the following system:

E_{1} = 0.13P

E_{2} = (29000-P)*0.04

2195 - E_{1} = (29000-P)*0.04

2195 - 0.13P = 1160 - 0.04P

0.09P = 2195 - 1160

P = \frac{2195 - 1160}{0.09}

P = 11500

$11,500 was invested at 13%.

29000 - 11500 = 17500

$17,500 was invested at 4%

Q 16. The energy is 308.7 J.

Q 17. The energy is 896000 J.

Step-by-step explanation:

Q 16. Given,

Mass (m) of the carriage and baby =  1.5 kg

Height (h) = 21 m

To find the energy.

We will find the potential energy as it rests at the top.

Formula

Potential energy = mgh where g be the gravitational force of the earth = 9.8m/s²

So,

Energy = 1.5×9.8×21 J

= 308.7 J.

Hence,

The energy is 308.7 J.

Q 17. Given,

Mass (m) = 1120 kg

Speed (v) = 40 m/s

To find out the energy.

We will find out the kinetic energy as the car is in motion.

Formula

Kinetic energy = \frac{1}{2}mv²

So,

Energy = \frac{1}{2}×1120×40² J

= 896000 J

Hence,

The energy is 896000 J.
