Answer: 180 = 30 + (x + 60)

Step-by-step explanation: Supplementary means that the angles add together to 180 degrees. This equations shows that angle A (30 degrees) plus angle B (x + 60) equal 180. If you solve the equation you will find that angle B is equal to 150 degrees, and that x = 90.

(b) If A(t) is the amount of the investment at time t for the case of continuous compounding, write a differential equation sati

Fantom [35]

Answer:

$A'(t) = rA(t)$

Step-by-step explanation:

Given

$A(t) \to$ Amount

Required

The differential equation

The equation for the amount is:

$A(t) = A_0 * e^{rt}$

Where:

$A_0 \to$ initial amount

$r \to$ rate

$t \to$ time

Differentiate $A(t) = A_0 * e^{rt}$

$A'(t) = A_0 * r * e^{rt}$

So, we have:

$A'(t) = rA_0 * e^{rt}$

From the question, we have: $A(t) = A_0 * e^{rt}$

So, the equation becomes

$A'(t) = rA(t)$

What equation is equivalent to 9x - 3 = 729? 9x - 3 = 981 9x - 3 = 93 3x - 3 = 36 32x - 3 = 36

lilavasa [31]

Answer:

Option 2nd is correct

$9^x-3 =9^3$

Step-by-step explanation:

Given the equation:

$9^x-3 = 729$

We can write 729 as

$729 = 9 \cdot 9 \cdot 9 = 9^3$

then;

$9^x-3 =9^3$

Therefore, the equation which is equivalent to $9^x-3 = 729$ is, $9^x-3 =9^3$
