AB and CD are straight lines. Find AOD.

Anon25 [30]

Answer:

106°

Step-by-step explanation:

AOD = COB (because of vertical angles)

COB = COF + FOB

COF = 90

FOB = 16

COB = 90 + 16 = 106

AOD = 106

Hope this helps :)

Have a nice day!

How long will it take for the money to triple? Compounded continuously.

bezimeni [28]

If e^(rt) is 3, then taking logarithms tells you

... rt = ln(3)

So, the time to triple the amount is

... t = ln(3)/0.0275 ≈ 39.95 . . . . years

5. What property of equality is used to transform the equation from the first step to the second step?

Novay_Z [31]

Answer: The multiplication property of equality is used to transform the equation from the first step to the second step.

Explanation:

The multiplication property states that if any number is multiplied both side of a equation the equation doesn't change.

If x = y and we multiply both side by m, then xm = ym is equivalent to x = y.

The given expression is,

$\frac{x}{5}=2$

Use multiplication property of equality, multiply 5 both sides,

$x=2\times5$

$x=10$

Therefore, the multiplication property of equality is used to transform the equation from the first step to the second step.
