By comparing the perimeters, we can deduce the scaling factor:

$k = \dfrac{34}{20} = 1.7$

The areas scale with the square of the scaling factor, so the new area is

$19.6 \cdot 1.7^2 = 56.644$

If 2x - 5y – 7 = 0 is perpendicular to the line ax - y - 3 = 0 what is the value of a ?

faltersainse [42]

Answer:

D) a = - 5/2

Step-by-step explanation:

2x -5y - 7 = 0

5y = 2x - 7

y = 2/5 x - 7

the slope of this line is therefore 2/5 (factor of x).

the perpendicular slope is then (exchange y and x and flip the sign) -5/2, which is then a and the factor of x.

Answer:

Investment amount after 9 years = 14715.12$

Explanation:

It is given to use continuous change function, $A(t) = Pe^{rt}$

Here P = Principal = 10500$

r = Rate of increase = 0.0375

t = Number of years = 9

$A(t) = Pe^{rt}\\ \\ A(t) = 10500*e^{0.0375*9}=14715.12$

So, investment amount after 9 years = 14715.12$
