1. Calculate the simple interest over an amount of N$ 2500 that is invested for 3 years and 6 months at a rate of 7% pa.

Umnica [9.8K]

Answer:

N$ 612.5

Step by step explaination:

Given,

Principal or'P'=N$2500

Time or'n'=3 years & 6 months or 3.5 years

Rate of profit or 'r'=7% or 7/100

Profit or 'I'=?

_____________________________________

We know,

I=P*n*r

I=2500*3.5*7/100

I=612.5

So,simple interest is N$ 612.5.

If y= 2x-3 were chnged to y=2x+5 how would the graph of the new function compare with the original

ivanzaharov [21]

The new function moved up by 8 units from the original.

The only difference in the functions is the y-intercept. The slope remained the same ( $2$ ), but the y-intercept went up by 8, meaning the function moved up 8 units.

See the attached image for a graph of both functions. The new function is the solid blue line.

Answer:

$\displaystyle y=-\frac{1}{2}x+\frac{11}{2}$

Step-by-step explanation:

<u>Equation of the Line</u>

A line of slope m and y-intercept b can be expressed by the equation:

$y=mx+b$

The given line has the equation:

$8x-4y=-24$

Let's express it in the correct form:

$-4y=-24-8x$

Dividing by -4

$y=2x+6$

The slope of this line is m1=2. To find the slope m2 of a line perpendicular to this one, we use the following equation:

$m_1.m_2=-1$

Solving for m2:

$\displaystyle m_2=-\frac{1}{m_1}$

$\displaystyle m_2=-\frac{1}{2}$

The required equation has the form:

$\displaystyle y=-\frac{1}{2}x+b$

To find b, we use the point (3,4) through which the line passes:

$\displaystyle 4=-\frac{1}{2}(3)+b$

$\displaystyle b=4+\frac{3}{2}=\frac{11}{2}$

Thus the equation of the line is:

$\boxed{\displaystyle y=-\frac{1}{2}x+\frac{11}{2}}$
